E-mu Systems was a software synthesizer , audio interface , MIDI interface, and MIDI keyboard manufacturer. Founded in 1971 as a synthesizer maker, E-mu was a pioneer in samplers , sample-based drum machines and low-cost digital sampling music workstations .
79-588: After its acquisition in 1993, E-mu Systems was a wholly owned subsidiary of Creative Technology, Ltd . In 1998, E-mu was combined with Ensoniq , another synthesizer and sampler manufacturer previously acquired by Creative Technology. E-mu was last based in Scotts Valley, California , on the outskirts of Silicon Valley . E-mu Systems was founded in Santa Cruz, CA by Dave Rossum, a UCSC student and two of his friends from Caltech , Steve Gabriel and Jim Ketcham, with
158-469: A PCI card is used for audio input and output, the algorithms no longer run on dedicated hardware but in software on the PC. Proteus X , a software-based sample player, was released in 2005. During 2003-2007, E-mu designed and published a series of high-fidelity "Digital Audio Systems" (computer sound cards), intended for professional, semi-professional and computer audio enthusiast use. They were released under
237-443: A serial , lane-based architecture. PCI's heyday in the desktop computer market was approximately 1995 to 2005. PCI and PCI-X have become obsolete for most purposes and has largely disappeared from many other modern motherboards since 2013; however they are still common on some modern desktops as of 2020 for the purposes of backward compatibility and the relative low cost to produce. Another common modern application of parallel PCI
316-465: A "DSP", hoping to associate the product with a digital signal processor (the DSP could encode/decode ADPCM in real time, but otherwise had no other DSP-like qualities). Monaural Sound Blaster cards were introduced in 1989, and Sound Blaster Pro stereo cards followed in 1992. The 16-bit Sound Blaster AWE32 added Wavetable MIDI, and AWE64 offered 32 and 64 voices. Sound Blaster achieved competitive control of
395-555: A "stem cell-like" processor which would give a 100-fold increase in supercomputing power over current technology, as well as advances in consumer 3D graphics. At CES 2009, it was revealed to be the ZMS-05 processor from ZiiLABS , a subsidiary formed from the combining of 3DLabs and Creative's Personal Digital Entertainment division. In November 2012, the firm announced it has entered into an agreement with Intel Corporation for Intel to license technology and patents from ZiiLABS Inc. Ltd,
474-454: A 100-pin stacking connector, while Type III uses a 124-pin edge connector, i.e. the connector for Types I and II differs from that for Type III, where the connector is on the edge of a card, like with a SO-DIMM . The additional 24 pins provide the extra signals required to route I/O back through the system connector (audio, AC-Link , LAN , phone-line interface). Type II cards have RJ11 and RJ45 mounted connectors. These cards must be located at
553-647: A PC add-on card. Sim established Creative Labs, Inc. in the United States' Silicon Valley and convinced software developers to support the sound card, renamed Game Blaster and marketed by RadioShack 's Tandy division. The success of this audio interface led to the development of the standalone Sound Blaster sound card , introduced at the 1989 COMDEX show just as the multimedia PC market, fueled by Intel's 386 CPU and Microsoft Windows 3.0, took off. The success of Sound Blaster helped grow Creative's revenue from US$ 5.4 million in 1989 to US$ 658 million in 1994. In 1993,
632-404: A brutal market share decline caused by intense competition from Media Vision at the high end and Aztech at the low end. Sorkin, in particular, dramatically strengthened the company's brand position through crisp licensing and an aggressive defense of Creative's intellectual property positions while working to shorten product development cycles. At the same time, Esber and the original founders of
711-495: A computer is first turned on, all PCI devices respond only to their configuration space accesses. The computer's BIOS scans for devices and assigns Memory and I/O address ranges to them. If an address is not claimed by any device, the transaction initiator's address phase will time out causing the initiator to abort the operation. In case of reads, it is customary to supply all-ones for the read data value (0xFFFFFFFF) in this case. PCI devices therefore generally attempt to avoid using
790-524: A counterclaim stating the firm was intentionally interfering with its business prospects, had defamed them, commercially disparaged, engaged in unfair competition with intent to slow down Aureals sales, and acted fraudulently. The suit had come only days after Aureal gained a fair market with the AU8820 Vortex1. In August 1998, the Sound Blaster Live! was the firm's first sound card developed for
869-420: A device signals its need for service by performing a memory write, rather than by asserting a dedicated line. This alleviates the problem of scarcity of interrupt lines. Even if interrupt vectors are still shared, it does not suffer the sharing problems of level-triggered interrupts. It also resolves the routing problem, because the memory write is not unpredictably modified between device and host. Finally, because

It incorporates Dolby Atmos surround processing, and also features Creative's EAX 15.2 Dimensional Audio to extract, enhance and upscale sound from legacy material. The audio and video engine of the X-Fi Sonic Carrier are powered by 7 processors with a total of 14 cores. It supports both local and streaming video content at up to 4K 60 fps, as well as 15.2 channels of high resolution audio playback. It also comes with 3 distinct wireless technologies that allow multi-room Wi-Fi, Bluetooth, and
1027-537: A payment of approximately $ 470,000. In 2007, Creative voluntarily delisted itself from NASDAQ , where it had the symbol of CREAF. Its stocks are now solely on the Singapore Exchange (SGX-ST). In early 2008, Creative Labs' technical support centre, located in Stillwater, Oklahoma, US laid off several technical support staff, furthering ongoing concerns surrounding Creative's financial situation. Later that year,
1106-493: A protocol so that the interrupt-request (IRQ) lines can be shared. The PCI bus includes four interrupt lines, INTA# through INTD#, all of which are available to each device. Up to eight PCI devices share the same IRQ line (INTINA# through INTINH#) in APIC -enabled x86 systems. Interrupt lines are not wired in parallel as are the other PCI bus lines. The positions of the interrupt lines rotate between slots, so what appears to one device as

ZiiLABS (still wholly owned by Creative) continues to retain all ownership of its StemCell media processor technologies and patents, and will continue to supply and support its ZMS series of chips to its customers. From 2014 to 2017, Creative's revenue from audio products have contracted at an average of 15% annually, due to increased competition in
1264-488: A write must affect only the enabled bytes in the target PCI device. They are of little importance for memory reads, but I/O reads might have side effects. The PCI standard explicitly allows a data phase with no bytes enabled, which must behave as a no-op. PCI has three address spaces: memory, I/O address, and configuration. Memory addresses are 32 bits (optionally 64 bits) in size, support caching and can be burst transactions. I/O addresses are for compatibility with
1343-508: A zero-latency speaker-to-speaker link to up to 4 subwoofer units. Peripheral Component Interconnect Peripheral Component Interconnect ( PCI ) is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any given processor 's native bus. Devices connected to
1422-622: Is a Singaporean multinational electronics company mainly dealing with audio technologies and products such as speakers, headphones, sound cards and other digital media . Founded by Sim Wong Hoo , Creative was highly influential in the advancement of PC audio in the 1990s following the introduction of its Sound Blaster card and technologies; the company continues to develop Sound Blaster products including embedding them within partnered mainboard manufacturers and laptops. The company also has overseas offices in Shanghai , Tokyo , Dublin and
1501-562: Is in industrial PCs , where many specialized expansion cards, used here, never transitioned to PCI Express, just as with some ISA cards. Many kinds of devices formerly available on PCI expansion cards are now commonly integrated onto motherboards or available in USB and PCI Express versions. Work on PCI began at the Intel Architecture Labs (IAL, also Architecture Development Lab) c. 1990 . A team of primarily IAL engineers defined
1580-475: Is installed into a PCI-X bus capable of 133 MHz, the entire bus backplane will be limited to 66 MHz. To get around this limitation, many motherboards have two or more PCI/PCI-X buses, with one bus intended for use with high-speed PCI-X peripherals, and the other bus intended for general-purpose peripherals. Many 64-bit PCI-X cards are designed to work in 32-bit mode if inserted in shorter 32-bit connectors, with some loss of performance. An example of this
1659-496: Is meant to know this, and set the "interrupt line" field in each device's configuration space indicating which IRQ it is connected to. PCI interrupt lines are level-triggered . This was chosen over edge-triggering to gain an advantage when servicing a shared interrupt line, and for robustness: edge-triggered interrupts are easy to miss. Later revisions of the PCI specification add support for message-signaled interrupts . In this system,

#17330851187231738-485: Is required to implement a timer, called the Latency Timer, that limits the time that device can hold the PCI bus. The timer starts when the device gains bus ownership, and counts down at the rate of the PCI clock. When the counter reaches zero, the device is required to release the bus. If no other devices are waiting for bus ownership, it may simply grab the bus again and transfer more data. Devices are required to follow

On January 4, 2023, Sim died at age 67, with president of Creative Labs Business Unit Song Siow Hui appointed as interim CEO. Creative's Sound Blaster sound card
1896-617: Is the Adaptec 29160 64-bit SCSI interface card. However, some 64-bit PCI-X cards do not work in standard 32-bit PCI slots. Installing a 64-bit PCI-X card in a 32-bit slot will leave the 64-bit portion of the card edge connector not connected and overhanging. This requires that there be no motherboard components positioned so as to mechanically obstruct the overhanging portion of the card edge connector. PCI brackets heights: PCI Card lengths (Standard Bracket & 3.3 V): PCI Card lengths (Low Profile Bracket & 3.3 V): Mini PCI
1975-512: Is the same one designed by E-MU and used in Creative's Sound Blaster Audigy2 cards (and hence capable of 24-bit 192 kHz PCM sound), official press releases for the E-MU sound cards have emphasized Creative's lack of input on the design, and the in-house development of the cards and drivers — that is, they wanted to distinguish their "own" series from Creative's signature Sound Blasters. Notably,
2054-578: The Linn LM-1 . Recognizing the trend of digital samplers , they realized that E-mu had the technology to bring a lower-priced sampler to market. The Emulator debuted in 1981 at a list price of $ 7,900, significantly less than the $ 30,000 Fairlight. Following the Emulator, E-mu released the first programmable drum machine with samples built-in priced below $ 1,000, the E-mu Drumulator. The Drumulator's success

Aureal at this time were making fliers comparing their new AU8830 chips to the now shipping Sound Blaster Live! . The specifications within these fliers comparing the AU8830 to the Sound Blaster Live! EMU10K1 chip sparked another flurry of lawsuits against Aureal, this time claiming Aureal had falsely advertised
2212-632: The PCI Configuration Space , which uses a fixed addressing scheme, allows software to determine the amount of memory and I/O address space needed by each device. Each device can request up to six areas of memory space or input/output (I/O) port space via its configuration space registers. In a typical system, the firmware (or operating system ) queries all PCI buses at startup time (via PCI Configuration Space ) to find out what devices are present and what system resources (memory space, I/O space, interrupt lines, etc.) each needs. It then allocates
2291-636: The Silicon Valley . Creative Technology has been listed on the Singapore Exchange (SGX) since 1994. Creative Technology was founded in 1981 by childhood friends and Ngee Ann Polytechnic schoolmates Sim Wong Hoo and Ng Kai Wa. Originally a computer repair shop in Pearl's Centre in Chinatown , the company eventually developed an add-on memory board for the Apple II computer. Later, Creative spent $ 500,000 developing
2370-519: The Sound Blaster Live! 's capabilities. In December 1999, after numerous lawsuits, Aureal won a favourable ruling but went bankrupt as a result of legal costs and their investors pulling out. Their assets were acquired by Creative through the bankruptcy court in September 2000 for US$ 32 million. The firm had in effect removed their only major direct competitor in the 3D gaming audio market, excluding their later acquisition of Sensaura . In April 1999,

When C/MS struggled to acquire market share, Sim traveled from Singapore to Silicon Valley and negotiated a deal with RadioShack 's Tandy division to market the product as the Game Blaster. While the Game Blaster did not overcome AdLib's sound card market dominance, Creative used

2528-409: The "Made for iPod" program. On 22 March 2005, The Inquirer reported that Creative Labs had agreed to settle in a class action lawsuit about the way its Audigy and Extigy soundcards were marketed. The firm offered customers who purchased the cards up to a $ 62.50 reduction on the cost of their next purchase of its products, while the lawyers involved in filing the dispute against Creative received

E-mu also made unsuccessful attempts at breaking into the digital multitrack recorder with the Darwin hard-disk recording system. In 1998, E-mu was combined with Ensoniq , another synthesizer and sampler manufacturer previously acquired by Creative Technology. In 2001 E-mu's sound modules were repackaged in
2844-635: The Cubic CT, an IBM-compatible PC adapted for the Chinese language and featuring multimedia features like enhanced color graphics and a built-in audio board capable of producing speech and melodies. With lack of demand for multilingual computers and few multimedia software applications available, the Cubic was a commercial failure. Shifting focus from language to music, Creative developed the Creative Music System,
2923-510: The INTA# line is INTB# to the next and INTC# to the one after that. Single-function devices usually use their INTA# for interrupt signaling, so the device load is spread fairly evenly across the four available interrupt lines. This alleviates a common problem with sharing interrupts. The mapping of PCI interrupt lines onto system interrupt lines, through the PCI host bridge, is implementation-dependent. Platform-specific firmware or operating system code
3002-560: The Intel x86 architecture 's I/O port address space. Although the PCI bus specification allows burst transactions in any address space, most devices only support it for memory addresses and not I/O. Finally, PCI configuration space provides access to 256 bytes of special configuration registers per PCI device. Each PCI slot gets its own configuration space address range. The registers are used to configure devices memory and I/O address ranges they should respond to from transaction initiators. When

The exceptions are: Notes: Most 32-bit PCI cards will function properly in 64-bit PCI-X slots, but the bus clock rate will be limited to the clock frequency of the slowest card, an inherent limitation of PCI's shared bus topology. For example, when a PCI 2.3, 66-MHz peripheral
3160-720: The PC audio market by 1992, the same year that its main competitor, Ad Lib, Inc., went bankrupt. In the mid-1990s, following the launch of the Sound Blaster 16 and related products, Creative Technologies' audio revenue grew from US$ 40 million to nearly US$ 1 billion annually. The sixth generation of Sound Blaster sound cards introduced SBX Pro Studio, a feature that restores the highs and lows of compressed audio files, enhancing detail and clarity. SBX Pro Studio also offers user settings for controlling bass and virtual surround. The Creative X-Fi Sonic Carrier, launched in January 2016, consists of

3318-408: The PCI bus. Any number of bus masters can reside on the PCI bus, as well as requests for the bus. One pair of request and grant signals is dedicated to each bus master. Typical PCI cards have either one or two key notches, depending on their signaling voltage. Cards requiring 3.3 volts have a notch 56.21 mm from the card backplate; those requiring 5 volts have a notch 104.41 mm from
3397-616: The Proteus XR, an orchestral version, and a world music version. In 1987, E-mu's SP-1200 drum sampler offered an "all-in-one" box for sequencing not only drum sounds, but looping samples, and it quickly became the instrument of choice for hip hop producers. In 1993, E-mu was acquired by Creative Technology (the Singaporean parent company of Creative Labs) and began working on PC sound card synthesis. Creative Wave Blaster II and Sound Blaster AWE32 used EMU8000 effect processor. Throughout
3476-409: The abilities of PCI. The preferred interface for video cards then became Accelerated Graphics Port (AGP), a superset of PCI, before giving way to PCI Express. The first version of PCI found in retail desktop computers was a 32-bit bus using a 33 MHz bus clock and 5 V signaling, although the PCI 1.0 standard provided for a 64-bit variant as well. These have one locating notch in

With the exception of the unique dual address cycle, the least significant bit of the command code indicates whether the following data phases are a read (data sent from target to initiator) or a write (data sent from an initiator to target). PCI targets must examine

PCI was immediately put to use in servers, replacing Micro Channel architecture (MCA) and Extended Industry Standard Architecture (EISA) as the server expansion bus of choice. In mainstream PCs, PCI was slower to replace VLB , and did not gain significant market penetration until late 1994 in second-generation Pentium PCs. By 1996, VLB
3713-587: The audio space. At the Consumer Electronics Show (CES) in Las Vegas in January 2018, its Super X-Fi dongle won the Best of CES 2018 Award by AVS Forum. The product was launched after more than $ 100 million in investment and garnered positive analyst reports. This new technology renewed interest in the company and likely helped to raise its share price from S$ 1.25 to S$ 8.75 within a 2-week period. The company
3792-403: The backplate. This allows cards to be fitted only into slots with a voltage they support. "Universal cards" accepting either voltage have both key notches. The PCI connector is defined as having 62 contacts on each side of the edge connector , but two or four of them are replaced by key notches, so a card has 60 or 58 contacts on each side. Side A refers to the 'solder side' and side B refers to
3871-536: The card. Version 2.0 of the PCI standard introduced 3.3 V slots, physically distinguished by a flipped physical connector to prevent accidental insertion of 5 V cards. Universal cards, which can operate on either voltage, have two notches. Version 2.1 of the PCI standard introduced optional 66 MHz operation. A server-oriented variant of PCI, PCI Extended ( PCI-X ) operated at frequencies up to 133 MHz for PCI-X 1.0 and up to 533 MHz for PCI-X 2.0. An internal connector for laptop cards, called Mini PCI ,
3950-566: The cards and drivers entirely omit internal ' wavetable ' sample-based MIDI synthesis, Creative's proprietary EAX sound routines and basically anything commonly associated with the parent company. Although the cards were rushed into market and originally came bundled with fairly raw drivers (which have subsequently received periodical major improvements and even additions beyond the advertised specifications), they have generally met with rather favourable reviews. Creative Technology Creative Technology Ltd. , or Creative Labs Pte Ltd. ,
4029-416: The company faced a public-relations backlash when it demanded that a user named "Daniel_K" cease distributing modified versions of drivers for Windows Vista which restored functionality that had been available in drivers for Windows XP. The company deleted his account from its online forums but reinstated it a week later. In January 2009, the firm generated Internet buzz with a mysterious website promising

#17330851187234108-613: The company had differences of opinion on the strategy and positioning of the company. Esber exited in 1995, followed quickly by Buchanan and Pomerantz. Following Esber's departure, Sorkin was promoted to General Manager of Audio and Communication Products and later Executive Vice-president of Business Development and Corporate Investments, before leaving Creative in 1996 to run Elon Musk 's first startup and Internet pioneer Zip2 . By 1996, Creative's revenues had peaked at US$ 1.6 billion. With pioneering investments in VOIP and media streaming, Creative
4187-429: The data phases must be in the same direction. Either party may pause or halt the data phases at any point. (One common example is a low-performance PCI device that does not support burst transactions , and always halts a transaction after the first data phase.) Any PCI device may initiate a transaction. First, it must request permission from a PCI bus arbiter on the motherboard. The arbiter grants permission to one of
4266-541: The edge of the computer or docking station so that the RJ11 and RJ45 ports can be mounted for external access. Mini PCI is distinct from 144-pin Micro PCI. PCI bus traffic consists of a series of PCI bus transactions. Each transaction consists of an address phase followed by one or more data phases . The direction of the data phases may be from initiator to target (write transaction) or vice versa (read transaction), but all of

In 1972, E-mu became a company, developing and patenting a digitally scanned polyphonic keyboard (1973), licensed for use by Oberheim Electronics in the 4-Voice and 8-Voice synthesizers and by Dave Smith in the Sequential Circuits Prophet-5 . E-mu, along with Solid State Micro Technology (SSM), also developed several synthesizer module IC chips , that were used by both E-mu and many other synthesizer companies. With
4661-489: The initiator transmits the high 32 address bits, plus the real command code. The transaction operates identically from that point on. To ensure compatibility with 32-bit PCI devices, it is forbidden to use a dual address cycle if not necessary, i.e. if the high-order address bits are all zero. While the PCI bus transfers 32 bits per data phase, the initiator transmits 4 active-low byte enable signals indicating which 8-bit bytes are to be considered significant. In particular,
4740-406: The kinds of functions a Mini PCI card can perform. Many Mini PCI devices were developed such as Wi-Fi , Fast Ethernet , Bluetooth , modems (often Winmodems ), sound cards , cryptographic accelerators , SCSI , IDE – ATA , SATA controllers and combination cards. Mini PCI cards can be used with regular PCI-equipped hardware, using Mini PCI-to-PCI converters . Mini PCI has been superseded by
4819-621: The message signaling is in-band , it resolves some synchronization problems that can occur with posted writes and out-of-band interrupt lines. PCI Express does not have physical interrupt lines at all. It uses message-signaled interrupts exclusively. These specifications represent the most common version of PCI used in normal PCs: The PCI specification also provides options for 3.3 V signaling, 64-bit bus width, and 66 MHz clocking, but these are not commonly encountered outside of PCI-X support on server motherboards. The PCI bus arbiter performs bus arbitration among multiple masters on

#17330851187234898-497: The much narrower PCI Express Mini Card Mini PCI cards have a 2 W maximum power consumption, which limits the functionality that can be implemented in this form factor. They also are required to support the CLKRUN# PCI signal used to start and stop the PCI clock for power management purposes. There are three card form factors : Type I, Type II, and Type III cards. The card connector used for each type include: Type I and II use

The card names are number-coded for the number of physical inputs and outputs: 0404, 1212m, 1616, 1616m, 1820 and 1820m, where 1616 is a CardBus version and the rest for PCI, while "m" denotes extra high-quality analogue outputs and inputs. The 1820m was touted as the series' flagship product until the 1616 and 1616M were released (A PCI version of
5056-433: The operating system. In addition, there are PCI Latency Timers that are a mechanism for PCI Bus-Mastering devices to share the PCI bus fairly. "Fair" in this case means that devices will not use such a large portion of the available PCI bus bandwidth that other devices are not able to get needed work done. Note, this does not apply to PCI Express. How this works is that each PCI device that can operate in bus-master mode
5135-552: The platform to create the first Sound Blaster , which retained CM/S hardware and added the Yamaha YM3812 chip found on the AdLib card, as well as adding a component for playing and recording digital samples. Creative aggressively marketed the "stereo" aspect of the Sound Blaster (only the C/MS chips were capable of stereo, not the complete product) to calling the sound producing micro-controller
5214-527: The requesting devices. The initiator begins the address phase by broadcasting a 32-bit address plus a 4-bit command code, then waits for a target to respond. All other devices examine this address and one of them responds a few cycles later. 64-bit addressing is done using a two-stage address phase. The initiator broadcasts the low 32 address bits, accompanied by a special "dual address cycle" command code. Devices that do not support 64-bit addressing can simply not respond to that command code. The next cycle,

The PCI configuration space also contains a small amount of device type information, which helps an operating system choose device drivers for it, or at least to have a dialogue with a user about the system configuration. Devices may have an on-board read-only memory (ROM) containing executable code for x86 or PA-RISC processors, an Open Firmware driver, or an Option ROM . These are typically needed for devices used during system startup, before device drivers are loaded by
5372-469: The serial PCI Express in c. 2004 . Since then, motherboard manufacturers have included progressively fewer PCI slots in favor of the new standard. Many new motherboards do not provide PCI slots at all, as of late 2013. PCI provides separate memory and memory-mapped I/O port address spaces for the x86 processor family, 64 and 32 bits , respectively. Addresses in these address spaces are assigned by software. A third address space, called
5451-404: The time was in development of their own in house PCI audio cards but were finding little success adopting the PCI standard. In January 1998 in order to quickly facilitate a working PCI audio technology, the firm made the acquisition of Ensoniq for US$ 77 million. On 5 March 1998 the firm sued Aureal with patent infringement claims over a MIDI caching technology held by E-mu Systems . Aureal filed
5530-430: The year after Creative's initial public offering, in 1992, former Ashton-Tate CEO Ed Esber joined Creative Labs as CEO to assemble a management team to support the company's rapid growth. Esber brought in a team of US executives, including Rich Buchanan (graphics), Gail Pomerantz (marketing), and Rich Sorkin (sound products, and later communications, OEM and business development). This group played key roles in reversing
5609-450: Was added to PCI version 2.2 for use in laptops and some routers; it uses a 32-bit, 33 MHz bus with powered connections (3.3 V only; 5 V is limited to 100 mA) and support for bus mastering and DMA . The standard size for Mini PCI cards is approximately a quarter of their full-sized counterparts. There is no access to the card from outside the case, unlike desktop PCI cards with brackets carrying connectors. This limits
5688-463: Was all but extinct, and manufacturers had adopted PCI even for Intel 80486 (486) computers. EISA continued to be used alongside PCI through 2000. Apple Computer adopted PCI for professional Power Macintosh computers (replacing NuBus ) in mid-1995, and the consumer Performa product line (replacing LC Processor Direct Slot (PDS)) in mid-1996. Outside the server market, the 64-bit version of plain PCI remained rare in practice though, although it
5767-482: Was among the first dedicated audio processing cards to be made widely available to the general consumer. As the first to bundle what is now considered to be a part of a sound card system: digital audio, on-board music synthesizer, MIDI interface and a joystick port, Sound Blaster rose to become a de facto standard for sound cards in PCs for many years. Creative Technology have made their own file format Creative Voice which has
5846-507: Was awarded to the firm for the invention of user interface for portable media players. This opened the way for potential legal action against Apple's iPod and the other competing players. The firm took legal actions against Apple in May 2006. In August, 2006, Creative and Apple entered into a broad settlement, with Apple paying Creative $ 100 million for the licence to use the Zen patent. The firm then joined
5925-551: Was first implemented in IBM PC compatibles , where it displaced the combination of several slow Industry Standard Architecture (ISA) slots and one fast VESA Local Bus (VLB) slot as the bus configuration. It has subsequently been adopted for other computer types. Typical PCI cards used in PCs include: network cards , sound cards , modems , extra ports such as Universal Serial Bus ( USB ) or serial , TV tuner cards and hard disk drive host adapters . PCI video cards replaced ISA and VLB cards until rising bandwidth needs outgrew
6004-680: Was followed by the Emulator II and III , the SP-12 drum sampler, and the Emax series of samplers. In 1990, E-mu introduced the Proteus , a rackmount sound module , containing pre-recorded samples in ROM . At its introduction, the Proteus had a relatively large library of high-quality samples priced much lower than the competition. The success of the Proteus spurred the development of several additional versions, including
6083-638: Was introduced in version 2.2 of the PCI specification. The PCI bus was also adopted for an external laptop connector standard – the CardBus . The first PCI specification was developed by Intel , but subsequent development of the standard became the responsibility of the PCI Special Interest Group ( PCI-SIG ). PCI and PCI-X sometimes are referred to as either Parallel PCI or Conventional PCI to distinguish them technologically from their more recent successor PCI Express , which adopted
6162-524: Was used for example by all (post-iMac) G3 and G4 Power Macintosh computers . Later revisions of PCI added new features and performance improvements, including a 66 MHz 3.3 V standard and 133 MHz PCI-X , and the adaptation of PCI signaling to other form factors. Both PCI-X 1.0b and PCI-X 2.0 are backward compatible with some PCI standards. These revisions were used on server hardware but consumer PC hardware remained nearly all 32-bit, 33 MHz and 5 volt. The PCI-SIG introduced
6241-613: Was well-positioned to take advantage of the Internet era, but ventured into the CD-ROM market and was eventually forced to write off nearly US$ 100 million in inventory when the market collapsed due to a flood of cheaper alternatives. The firm had maintained a strong foothold in the ISA PC audio market until 14 July 1997 when Aureal Semiconductor entered the soundcard market with their very competitive PCI AU8820 Vortex 3D sound technology.
