The Motorola 68020 is a 32-bit microprocessor from Motorola , released in 1984. A lower-cost version was also made available, known as the 68EC020 . In keeping with naming practices common to Motorola designs, the 68020 is usually referred to as the "020", pronounced "oh-two-oh" or "oh-twenty".
62-645: The 020 was in the market for a relatively short time. The Motorola 68030 was announced in September 1986 and began deliveries in the summer of 1987. Priced about the same as the 020 of the time, the 030 was significantly faster and quickly replaced in 020 in almost every use. At the time the Motorola 68000 was designed, Motorola's design and fabrication services were outdated. Although even small companies like MOS Technology and Zilog had moved on to silicon gate depletion mode NMOS logic on ever-larger wafers , Motorola
124-433: A burst mode for the caches, where four longwords can be loaded into the cache in a single operation. The MMU was mostly compatible with the external 68851 that would be used with the 68020, but being internal allowed it to access memory one cycle faster than a 68020/68851 combo. The 68030 did not include a built-in floating-point unit (FPU), and was generally used with the 68881 and the faster 68882 . The addition of
186-480: A much higher total pin count. By the early 1980s, similar limitations on all modern CPU designs led to the introduction of the pin grid array that replaced the DIP. For the new project, Motorola selected a 169-pin layout, giving them plenty of room to work with. The design ultimately used only 114 of them. A great debate broke out about how to refer to the underlying design of the new chip in marketing materials. Technically,
248-401: A multiprocessing system (which were removed in the 68060), some support for high-level languages which did not get used much (and was removed from future 680x0 processors), bigger multiply (32×32→64 bits) and divide (64÷32→32 bits quotient and 32 bits remainder) instructions, and bit field manipulations. The new addressing modes add scaled indexing and another level of indirection to many of
310-440: A multiprocessor system, coprocessors could not be shared between CPUs. To avoid problems with returns from coprocessor, bus error, and address error exceptions, it was generally necessary in a multiprocessor system for all CPUs to be the same model, and for all FPUs to be the same model as well. The new instructions include some minor improvements and extensions to the supervisor state, several instructions for software management of
372-401: A new fab, MOS-8, using 5-inch wafers and the latest HMOS process licensed from Intel . This line was capable of building all of the new techniques, but the 68000 went ahead with the older design as they were sure it would work. Moving to new design techniques would wait until the design was in the market. The conversion to the new design techniques took place during the Motorola 68010 effort,
434-485: A new watch band to commemorate the event. Meanwhile, Walker instituted a new policy at MOS-8 to improve the plant itself. He normally called meetings at 6:30 AM. If things were not going well, he would move that up to 5:30, and even 4:30. This provided a strong incentive to get the plant running. The production problems were soon ironed out, and volume deliveries began late that year. By this point, their workstation customers had already developed complete systems ready to use
496-686: A proper three-stage pipeline. Though the 68010 had a "loop mode", which sped loops through what was effectively a tiny instruction cache, it held only two short instructions and was thus little used. The 68020 replaced this with a proper instruction cache of 256 bytes, the first 68k series processor to feature true on-chip cache memory. The previous 68000 and 68010 processors could only access word (16-bit) and long word (32-bit) data in memory if it were word-aligned (located at an even address). The 68020 has no alignment restrictions on data access. Naturally, unaligned accesses are slower than aligned accesses because they required an extra memory access. The 68020 has
558-468: A relatively minor upgrade to the original design that added basic virtual memory support for the emerging Unix workstation market. As this effort was ongoing, Motorola was canvassing their customers for their desires for future developments in the line. These all pointed to a fully 32-bit implementation. Those using the 68k in Unix systems also stated they would purchase a floating point unit for every one of
620-459: A small 256-byte direct-mapped instruction cache, arranged as 64 four-byte entries. Although small, it still made a significant difference in the performance of many applications. The resulting decrease in bus traffic was particularly important in systems relying heavily on DMA . The 68020 has a coprocessor interface supporting up to eight coprocessors. The main CPU recognizes "F-line" instructions (with
682-445: A way of amortizing the high overhead. They often reuse advanced manufacturing processes, expensive safety certifications, specialized embedded software, computer-aided design software, electronic designs and mechanical subsystems. Research from 2000 has shown that firms with a persistent R&D strategy outperform those with an irregular or no R&D investment program. Research and development are very difficult to manage, since

#1732869172508744-442: Is a 32-bit microprocessor in the Motorola 68000 family . It was released in 1987. The 68030 was the successor to the Motorola 68020 , and was followed by the Motorola 68040 . In keeping with general Motorola naming, this CPU is often referred to as the 030 (pronounced oh-three-oh or oh-thirty ). The 68030 is essentially a 68020 with a memory management unit (MMU) and instruction and data caches of 256 bytes each. It added
806-622: Is a lower cost version of the Motorola 68020. The main difference is that the 68EC020 only has a 24-bit address bus, rather than the 32-bit address bus of the full 68020, and thus is only able to address 16 MB of memory. The Amiga 1200 computer and the Amiga CD32 game console use the cost-reduced 68EC020; the Namco System 22 , Taito F3 and Konami GX arcade boards also used this processor. The Atari Jaguar II prototype featured this to replace
868-653: Is appealing to bidders because they could gain technologies from acquisition targets. Therefore, firms may gain R&D profit that co-moves with takeover waves, causing risks to the company which engages in R&D activity. Global R&D management is the discipline of designing and leading R&D processes globally, across cultural and lingual settings, and the transfer of knowledge across international corporate networks. Former President Barack Obama requested $ 147.696 billion for research and development in FY 2012, 21% of which
930-508: Is asynchronous, so it is possible to run the coprocessors at a different clock rate than the CPU. Multiprocessing support is implemented externally by the use of an RMC pin to indicate an indivisible read-modify-write cycle in progress. All other processors have to hold off memory accesses until the cycle is complete. Software support for multiprocessing includes the TAS , CAS and CAS2 instructions. In
992-476: Is followed by textiles (19%), digital (18%), and aerospace (15%). Other sectors allocate less than 10% of their total investment to R&D. While 17% of the world’s top R&D investors are based in the European Union, they accounted for only 1% of acquisitions involving EU-based companies between 2013 and 2023. In 2015, research and development constituted an average 2.2% of the global GDP according to
1054-627: Is lower than the EU average of 18%. In 2022, 67% of enterprises in the same region deployed at least one sophisticated digital technology, and 69% EU firms did the same. As of 2023, European enterprises account for 18% of the world's top 2 500 R&D corporations, but just 10% of new entrants, compared to 45% in the United States and 32% in China. As of 2024, the electronics sector leads in R&D investment, with 28% of its total investment dedicated to it. This
1116-404: Is necessary as well due to the fierce competition and the evolving preferences of consumers. Without an R&D program, a firm must rely on strategic alliances , acquisitions , and networks to tap into the innovations of others. A system driven by marketing is one that puts the customer needs first, and produces goods that are known to sell. Market research is carried out, which establishes

R&D is crucial for acquiring larger shares of the market through new products. R&D&I represents R&D with innovation. New product design and development is often a crucial factor in the survival of a company. In a global industrial landscape that is changing fast, firms must continually revise their design and range of products. This
1240-596: Is remarkable, and usually gains a reputation for being a high technology company such as engineering company Ericsson 24.9%, or biotech company Allergan , which tops the spending table with 43.4% investment. Such companies are often seen as credit risks because their spending ratios are so unusual. Generally such firms prosper only in markets whose customers have extreme high technology needs, like certain prescription drugs or special chemicals, scientific instruments , and safety-critical systems in medicine, aeronautics or military weapons . The extreme needs justify
1302-446: Is the set of innovative activities undertaken by corporations or governments in developing new services or products. R&D constitutes the first stage of development of a potential new service or the production process. Although R&D activities may differ across businesses, the primary goal of an R&D department is to develop new products and services. R&D differs from the vast majority of corporate activities in that it

The 68020 has 32-bit internal and external data and address buses, compared to the early 680x0 models with 16-bit data and 24-bit address buses. The 68020's ALU is also natively 32-bit, so can perform 32-bit operations in one clock cycle, whereas
1612-611: The Office of Chief Scientist In the 1980s to 1992, the Chief scientist of Israel significantly expanded R&D subsidies in the Israeli industrial sector. Israel invested in the creation of clusters of startups in the high-tech sector as well as venture capital investments. In 1993, Israel initiated the Yozma program , which led to the doubling of value of Israel's 10 new venture capital funds in 3 years. In

More recently , the 68030 core has also been adapted by Freescale into a microcontroller for embedded applications. LeCroy has used the 68EC030 in certain models of their 9300 Series digital oscilloscopes including “C” suffix models and high performance 9300 Series models, along with

The first Macintosh with the 020 was the Macintosh II released in March 1987, two years after the 020 had become widely available, with low-volume initial shipments starting two months later. Only eighteen months later,
1860-425: The 020 and the new floating point unit, the Motorola 68881 . Systems were in the market only five or six months after the 020 had been announced. Design of the 020's follow-on began almost immediately. As part of their ongoing work with Hitachi, Motorola's fabrication system was finally catching up with the competition, as was their internal design workflow. This gave them considerably more room to work with, allowing
1922-454: The 020 was moving from the long-established NMOS logic design to a CMOS layout, which requires two transistors per gate. Common knowledge of the era suggested that CMOS cost four times as much as NMOS, and there was a significant amount of the market that believed "CMOS equals bad." The design was completed in the summer of 1983 and announced in June 1984. This "super chip" was significant news at

Kodak used it in the Ektaplus 7016PS, and Dataproducts used it in the LZR 1260. In 2014, Rochester Electronics re-established manufacturing capability for the 68020 microprocessor and it is still available today. Motorola 68030 The Motorola 68030 (" sixty-eight-oh-thirty ")
2046-530: The 68000 took a minimum of two clock cycles due to its 16-bit ALU. Newer packaging methods allowed the '020 to feature more external pins without the large size that the earlier dual in-line package method required. The 68EC020 lowered cost through a 24-bit address bus. The 68020 was produced at speeds ranging from 12 MHz to 33 MHz. The 68020 has a 32-bit arithmetic logic unit (ALU), 32-bit external data and address buses. It adds extra instructions and additional addressing modes. The 68020 (and 68030) has

It is used in the flight control and radar systems of the Eurofighter Typhoon combat aircraft. The Nortel Networks DMS-100 telephone central office switch also used the 68020 as the first microprocessor of the SuperNode computing core. The 68EC020
2170-556: The FPU was a major design note of the subsequent 68040. The 68030 lacks some of the 68020's instructions, but it increases performance by ≈5% while reducing power draw by ≈25%. The 68030 features 273,000 transistors. A lower-cost version was also released, the Motorola 68EC030, lacking the on-chip MMU. It was commonly available in both 132-pin QFP and 128-pin PGA packages.

The 68EC030 is a low cost version of the 68030, the difference between the two being that the 68EC030 omits the on-chip memory management unit (MMU) and is thus essentially an upgraded 68020. The 68EC030 was used as the CPU for the low-cost model of the Amiga 4000 , and on a number of CPU accelerator cards for
2294-603: The QFP package limited that variant to 33 MHz; the PGA 68030s included 40 MHz and 50 MHz versions. There was also a small supply of QFP packaged EC variants. The 68030 can be used with the 68020 bus, in which case its performance is similar to 68020 that it was derived from. However, the 68030 provides an additional synchronous bus interface which, if used, accelerates memory accesses up to 33% compared to an equally clocked 68020. The finer manufacturing process allowed Motorola to scale
2356-540: The addition of larger processor caches , a built-in memory management unit (MMU) and other features. The Motorola 68030 was announced in September 1986, with deliveries to begin the next summer. Due to the changes in the production lines, the new 030 would have a lower launch price than the 020. There were significant differences between the 68000 and 020, especially the 32-bit memory interface. This required computer designs using it to be considerably different from earlier models. In contrast, there were few changes between

In the United States, a typical ratio of research and development for an industrial company is about 3.5% of revenues; this measure is called " R&D intensity ". A high technology company, such as a computer manufacturer, might spend 7% or a pharmaceutical companies such as Merck & Co. 14.1% or Novartis 15.1%. Anything over 15%
2480-553: The context of commerce , "research and development" normally refers to future-oriented, longer-term activities in science or technology , using similar techniques to scientific research but directed toward desired outcomes and with broad forecasts of commercial yield. Statistics on organizations devoted to "R&D" may express the state of an industry , the degree of competition or the lure of progress . Some common measures include: budgets , numbers of patents or on rates of peer-reviewed publications . Bank ratios are one of
2542-411: The defining feature of research is that the researchers do not know in advance exactly how to accomplish the desired result. As a result, "higher R&D spending does not guarantee more creativity, higher profit or a greater market share".

Two types of coprocessors were defined: floating point units ( MC68881 or MC68882 FPUs ) and the paged memory management unit ( MC68851 PMMU). Only one PMMU can be used with a CPU. In principle, multiple FPUs could be used with a CPU, but it was not commonly done. The coprocessor interface

The 68030 was used in many models of the Apple Macintosh II and Commodore Amiga series of personal computers , NeXT Cube , later Alpha Microsystems multiuser systems, and some descendants of the Atari ST line such as the Atari TT and the Atari Falcon . It was also used in Unix workstations such as
2728-445: The high risk of failure and consequently high gross margins from 60% to 90% of revenues. That is, gross profits will be as much as 90% of the sales cost, with manufacturing costing only 10% of the product price, because so many individual projects yield no exploitable product. Most industrial companies get 40% revenues only. On a technical level, high tech organizations explore ways to re-purpose and repackage advanced technologies as
2790-782: The invention. One way entrepreneurs can reduce these uncertainties is to buy the licence for a franchise, so that the know-how is already incorporated in the licence. In general, it has been found that there is a positive correlation between the research and development and firm productivity across all sectors, but that this positive correlation is much stronger in high-tech firms than in low-tech firms. In research done by Francesco Crespi and Cristiano Antonelli, high-tech firms were found to have "virtuous" Matthew effects while low-tech firms experienced "vicious" Matthew effects, meaning that high-tech firms were awarded subsidies on merit while low-tech firms most often were given subsidies based on name recognition, even if not put to good use. While

The high tech sector in Israel, known as Silicon Wadi , which earned Israel the nickname - Start-up Nation , was ranked the 4th leading startup ecosystem in the world by Startup genome with a value of $ 253billion in 2023. Europe is lagging behind in R&D investments from the past two decades. The target of 3% of gross domestic product (GDP)
2914-551: The late-90s used the 68020, including the LeCroy 9300 Series (higher end models including "C" suffix models used the more powerful 68EC030 ; the 9300 models with a 68020 processor can be upgraded to the 68EC030 with a change of the CPU board) and the earlier LeCroy 9400 series (all models excluding the 9400/9400A which used the 68000 ), along with certain Tektronix TDS Series models. The HP 54520, 54522, 54540 and 54542 also use
2976-485: The machines if one was available. The original 68000 had been designed as a hybrid 16/32-bit system largely because the maximum number of pins available on dual inline packages (DIPs) was 64, and even at that size, packaging of this size was highly problematic. By reducing the number of address pins to 24, and the data pins to only 16, there were enough free pins to implement all the other needed lines, like interrupts and power supplies. The 24-pin address bus meant that
3038-531: The memory could only be 16 MB in total, which was at this point becoming a limitation. The 16-bit data bus meant reading a 32-bit word from that memory required two bus cycles. A design that had 32 pins for both the address and data busses would access data twice as fast, making the machine that much faster even with no other changes. Moving to 32 bit addressing would also make the implementation of virtual memory easier, and allow for more than 16 MB of random access memory . But doing so would also demand
3100-409: The needs of consumers and the potential niche market of a new product. If the development is technology driven, R&D is directed toward developing products to meet the unmet needs. In general, research and development activities are conducted by specialized units or centers belonging to a company, or can be out-sourced to a contract research organization, universities , or state agencies.

With full 32-bit internal and external address buses, the address registers (A0 through A7) could utilize their full 32-bit width, and were capable of addressing the entire 4 GB address space. The larger effective widths of the address registers presented some problem for earlier software that was not considered " 32-bit clean ". Some programs used the high 8 bits (bits 24-31) of addresses to contain various flag bits, with

That is, for every wafer sent through the multi-step process, zero working chips would be produced. Gary Johnson concluded the problem was the floor manager of MOS-8, Tom Felesi, and decided to replace him with Bill Walker, who

Business R&D is risky for at least two reasons. The first source of risks comes from R&D nature, where R&D project could fail without residual values. The second source of risks comes from takeover risks, which means R&D

The launch price was quoted at $ 487 each, about the same as the 68000 when it was launched in 1980, but the 68000 was now available for about $ 15. However, it was understood that it would be some time before computers using the new chip would be available, as existing designs would have to be heavily modified to take advantage of its performance. The announcement led to Motorola's customers clamouring for supply. At this point, serious supply problems became evident. The design had been laid out to be built in

According to National Science Foundation in U.S., in 2015, R&D expenditures performed by federal government and local governments are 54 and 0.6 billions of dollars. The federal research and development budget for fiscal year 2020 was $ 156 billion, 41.4% of which was for the Department of Defense ( DOD ). DOD's total research, development, test, and evaluation budget
3720-519: Was meant to be reached by 2020, but the current amount is below this target. This also causes a digital divide among countries since only a few EU Member States have R&D spending. Research and innovation in Europe are financially supported by the programme Horizon 2020 , which is open to participation worldwide. A notable example is the European environmental research and innovation policy , based on
