92-657: A TV encoder. Under Windows, the driver supports DirectX 10.0, Shader Model 4.0 and OpenGL 1.5. Under Linux, OpenGL 2.1 is supported. Integrated graphics found on B43, Q43 and Q45 chipsets . The GMA X4500 and the GMA X4500HD for desktop platforms were launched in June 2008. The GMA X4500 is used in G43 chipset and the GMA X4500HD is used in the G45 chipset . The GMA X4500 is also used in

138-401: A compile- link - debug workflow; integrating it with other tools is not always easy. For instance, GCC uses a step called fold that is key to the overall compile process, which has the side effect of translating the code tree into a form that looks unlike the original source code. If an error is found during or after the fold step, it can be difficult to translate that back into one location in

184-684: A mixed compile time and program performance benchmark. However, by 2019, Clang is significantly slower at compiling the Linux Kernel than GCC while remaining slightly faster at compiling LLVM. While Clang has historically been faster than GCC at compiling, the output quality has lagged behind. As of 2014, performance of Clang-compiled programs lagged behind performance of the GCC-compiled program, sometimes by large factors (up to 5.5x), replicating earlier reports of slower performance. Both compilers have evolved to increase their performance since then, with

230-558: A new compiler front end which supports C, Objective-C and C++. In July 2007, the project received the approval for becoming open-source. Clang works in tandem with LLVM. The combination of Clang and LLVM provides most of the toolchain for replacing the GCC stack . One of Clang's main goals is to provide a library-based architecture, so that the compiler could interoperate with other tools that interact with source code, such as integrated development environments (IDE). In contrast, GCC works in

276-771: A while MacBook and MacBook Pro notebooks instead shipped with a far more powerful NVIDIA GeForce 9400M, and the 15" and 17" MacBook Pro notebooks shipped with an additional GeForce 9600GT supporting hybrid power to switch between GPUs. The NVIDIA GeForce 9400M chipset implemented in Apple MacBooks did not support composite or S-video output. FreeBSD 8.0 supports the following Intel graphic chipsets: i810, i810-DC100, i810e, i815, i830M, 845G, 852GM, 855GM, 865G, 915G, 915GM, 945G, 945GM, 965G, 965Q, 946GZ, 965GM,945GME, G33, Q33, Q35, G35, GM45, G45, Q45, G43 and G41 chipsets. In practice, chipsets through 4500MHD are supported with DRM and 3D using FreeBSD 9. Work to integrate GEM and KMS

322-515: Is a compiler front end for the programming languages C , C++ , Objective-C , Objective-C++ , and the software frameworks OpenMP , OpenCL , RenderScript , CUDA , SYCL , and HIP . It acts as a drop-in replacement for the GNU Compiler Collection (GCC), supporting most of its compiling flags and unofficial language extensions. It includes a static analyzer , and several code analysis tools. Clang operates in tandem with

368-510: Is a low priority for GCC developers. As such, GCC does not integrate smoothly into Apple's integrated development environment (IDE). Finally, GCC's license agreement, the GNU General Public License (GPL) version 3 , requires developers who distribute extensions or modified versions of GCC to make their source code available, but LLVM's permissive software license doesn't require this. For these reasons, Apple developed Clang,

414-663: Is a very close relative of the GMA900/950, completely different from the GMA X3000 series. Supports up to 384 MB video memory (Using the Windows XP driver), DirectX 9.0c, Shader Model 2.0, OpenGL 1.4 with Microsoft Windows and OpenGL 2.1 with Linux. The 946GZ, Q963 and Q965 chipsets use the GMA 3000 graphics core. The GMA 3000 3D core is very different from the X3000, despite their similar names. It

460-442: Is based more directly on the previous generation GMA 900 and GMA 950 graphics, and belonging to the same "i915" family with them. It has pixel shaders which only support Shader Model 2.0b features, and the vertex shaders are still software-emulated. In addition, hardware video acceleration such as hardware-based iDCT computation, ProcAmp (video stream independent color correction ), and VC-1 decoding are not implemented in hardware. Of

506-576: Is the same graphic system as the GMA 500, but clocked at double the speed. (From 200 MHz to 400 MHz). This integrated graphics system was released in Intel Atom (Cedar Trail, 32 nm) and based on PowerVR SGX545 . Unlike the original PowerVR solution, this model is clocked at 400 MHz instead of 200 MHz. It is specifically found in the Intel Atom N2600 processor and Atom D2500 models. It supports DirectX version 9.0c. Similar to

552-609: Is under active development. Development versions of Flang were in progress as of October 2023 and could be downloaded from the LLVM Project. Clang is compatible with GCC. Its command-line interface shares many of GCC's flags and options. Clang implements many GNU language extensions and compiler intrinsics , some of which are purely for compatibility. For example, even though Clang implements atomic intrinsics which correspond exactly with C11 atomics , it also implements GCC's __sync_* intrinsics for compatibility with GCC and

598-677: The BIOS . Different modes are supported: The default setting in most BIOS is PAVP Lite. Within Intel HD Graphics , the successor of Intel GMA, a similar technology called Intel Insider exists. Mac OS X 10.4 Tiger supports the GMA 950, since it was used in previous revisions of the MacBook , Mac mini , and 17-inch iMac . It had been used in all Intel-based Mac minis until the Mac mini released on March 3, 2009). Mac OS X 10.5 Leopard contains drivers for

644-739: The C++ Standard Library (libstdc++). Clang also maintains application binary interface (ABI) compatibility with GCC-generated object code . In practice, Clang is a drop-in replacement for GCC. Clang's developers aim to reduce memory footprint and increase compiling speed compared to other compilers, such as GCC. In October 2007, they report that Clang compiled the Carbon libraries more than twice as fast as GCC, while using about one-sixth GCC's memory and disk space. By 2011, Clang seemed to retain this advantage in compiler performance. As of mid-2014, Clang still consistently compiles faster than GCC in

690-597: The G41 chipset , which was released in September 2008. The difference between the GMA X4500 and the GMA X4500HD is that the GMA X4500HD is capable of "full 1080p high-definition video playback, including Blu-ray disc movies" . Only GMA X4500HD, X4500MHD and X4700MHD has AVC HD decoding support. Like the X3500, X4500 supports DirectX 10 and Shader Model 4.0 features. Intel designed

736-558: The LLVM compiler back end and has been a subproject of LLVM 2.6 and later. As with LLVM, it is free and open-source software under the Apache 2.0 software license . Its contributors include Apple , Microsoft , Google , ARM , Sony , Intel , and AMD . Clang 17, the latest major version of Clang as of October 2023, has full support for all published C++ standards up to C++17 , implements most features of C++20 , and has initial support for

782-801: The PowerVR SGX and used it in the GMA 500 IGP for use with their Atom platform. With the introduction of the Platform Controller Hub , the Graphics Media Accelerator series ceased, and the CPU-based Intel HD and Iris Graphics series was created. The GMA 900 was the first graphics core produced under Intel's Graphics Media Accelerator product name, and was incorporated in the Intel 910G, 915G, and 915Gx chipsets . The 3D architecture of

828-533: The 64-bit GMA X3100 drivers later, and thus affected Macs were forced back to the 32-bit kernel despite being 64-bit clean in terms of hardware and firmware. No 64-bit drivers were offered in OS X Lion. Subsequently, OS X Mountain Lion dropped 32-bit kernel booting. The combination of these two changes in graphics driver code resulted in many Mac revisions being unable to upgrade to Mountain Lion, as their GPUs cannot be replaced. For

874-509: The Atom Z24xx ( Medfield ) platform as a series of ultra-low power processors for smartphones. While Intel indicates that this chip contains an Intel Graphics Media Accelerator, they do not specify a GPU model number. This GPU is known to be a PowerVR SGX540 . A revised version of the previous Intel SCH (System Controller Hub) for the Atom Z6xx series CPU codenamed Lincroft . Essentially, this

920-606: The Atom processor Z5xx series features a GMA 500 graphic system. Rather than being developed in-house, this core is a PowerVR SGX 535 core licensed from Imagination Technologies. Intel describes this as "a flexible, programmable architecture that supports shader-based technology, 2D, 3D and advanced 3D graphics, high-definition video decode, and image processing. Features include screen tiling, internal true color processing, zero overhead anti-aliasing, programmable shader 3D accelerator, and 32-bit floating-point operations." Intel launched

966-473: The GMA 3000-equipped chipsets, only the Q965 retains dual independent display support. The core speed is rated at 400 MHz with 1.6 Gpixel/s fill rate in datasheets, but was listed as 667 MHz core in the white paper. The memory controller can now address a maximum of 256 MB of system memory, and the integrated serial DVO ports have increased top speed to 270 Mpixel/s. The GMA X3000 for desktop

1012-485: The GMA 3600, but this version is clocked at 640 MHz. It is found in Atom N2800, Atom D2550, Atom D2500, Atom D2600 and Atom D2700 models. It supports DirectX version 9.0c. Protected Audio Video Path (PAVP) restricts the data path within a computer during video playback (e.g., Blu-ray discs). It is supported by newer chipsets (e.g. Intel G45 ) and operating systems (since Windows Vista ). PAVP can be configured in

1058-615: The GMA X3100, which were used in a recent revision of the MacBook range. Late-release versions of Mac OS X 10.4 also supported the GMA 900 due to its use in Apple's Developer Transition Kit (2005) , which was used in the PowerPC-to-Intel transition . However, special modifications to the kext file must be made to enable Core Image and Quartz Extreme. Although the new MacBook line no longer uses

1104-457: The GMA X3500 is very similar to the GMA X3000, with both graphics cores running at 667  MHz . The major difference between them is that the GMA X3500 supports Shader Model 4.0 and DirectX 10 , whereas the earlier X3000 supports Shader Model 3.0 and DirectX 9 . The X3500 also adds hardware-assistance for playback of VC-1 video. The GMA X3100 is the mobile version of the GMA X3500 used in

1150-548: The GMA X4500 to be 200% faster than the GMA 3100 ( G33 chipset ) in 3DMark06 performance and 70% faster than the GMA X3500 ( G35 chipset ). The GMA 4500MHD for laptops was launched on July 16, 2008. Featurewise, the 4500MHD is identical to its desktop cousin, the X4500HD. The GMA 4500MHD is used in GM45 chipsets, cantiga The GMA X4700MHD for laptops was launched in October 2008. It is

1196-496: The GMA ;900 was a significant upgrade from the previous Extreme 3D graphics processors. It is a 4 pixel per clock cycle design supporting DirectX 9 pixel shader model 2.0. It operates at a clock rate ranging from 160 to 333 MHz, depending on the particular chipset. At 333 MHz, it has a peak pixel fill-rate of 1332 megapixels per second. However, the architecture still lacks support for hardware transform and lighting and

1242-571: The Intel GL960/GM965 chipsets and also in the GS965 chipset. The X3100 supports hardware transform and lighting, up to eight programmable shader units, and up to 384 MB video memory. Its display cores can run up to 333 MHz on GM965 and 320 MHz on GL960. Its render cores can run up to 500 MHz on GM965 and 400 MHz on GL960. The X3100 display unit includes a 300 MHz RAMDAC, two 25–112 MHz LVDS transmitters, 2 DVO encoders, and

1288-593: The X3100, Mac OS X 10.5 shipped with drivers supporting it that require no modifications to the kext file. Mac OS X 10.6 (Snow Leopard), which includes a new 64-bit kernel in addition to the 32-bit one, does not include 64-bit X3100 drivers. This means that although the MacBooks with the X3100 have 64-bit capable processors and EFI, Mac OS X must load the 32-bit kernel to support the 32-bit X3100 drivers. November 9's 10.6.2 update ships with 64-bit X3100 drivers. Apple removed

1334-423: The advantages of the new GMA architecture come from the ability to flexibly switch as needed between executing graphics-related tasks or video-related tasks. While GMA performance has been widely criticized in the past as being too slow for computer games , sometimes being derogatorily nicknamed Intel 'GMD' (Graphics Media Decelerator) and being essentially referred to as the world's first "graphics decelerator" since

1380-484: The compiler's output. Modular design of the compiler can offer source code indexing, syntax checking, and other features normally associated with rapid application development systems. The parse tree is also more suitable for supporting automated code refactoring , as it directly represents the original source code. Clang compiles only C-like languages, such as C, C++, Objective-C, and Objective-C++. In many cases, Clang can replace GCC as needed, with no other effects on

1426-555: The confusion, it is listed as 667 MHz in Intel G965 white paper, but listed as 400 MHz in Intel G965 datasheet. There are various rules that define the IGP's processing capabilities. Memory controller can now address maximum 384 MB memory according to white paper, but only 256 MB in datasheet. GMA X3500 is an upgrade of the GMA X3000 and used in the desktop G35 . The shaders support shader model 4.0 features. Architecturally,

1472-481: The earlier Intel Extreme Graphics , and the Intel740 line, the latter of which was a discrete unit in the form of AGP and PCI cards with technology that evolved from companies Real3D and Lockheed Martin . Later, Intel integrated the i740 core into the Intel 810 northbridge . The original architecture of GMA systems supported only a few functions in hardware, and relied on the host CPU to handle at least some of

1518-553: The gap narrowing: libclang provides a C interface, providing a relatively small API. Exposed functionality includes: parsing source code into an AST , loading ASTs, traversing the AST, associating source locations with elements within the AST. This table presents only significant steps and releases in Clang history. Intel GMA This series targets the market of low-cost graphics solutions. The products in this series are integrated onto

1564-435: The graphics pipeline, further decreasing performance. However, with the introduction of Intel's 4th generation of GMA architecture ( GMA X3000 ) in 2006, many of the functions are now built into the hardware, providing an increase in performance. The 4th generation of GMA combines fixed function capabilities with a threaded array of programmable executions units, providing advantages to both graphics and video performance. Many of

1610-475: The impact of individual pipeline stalls.) However, due to the scalar nature of the execution units, they can only process data on a single pixel component at a time. The GMA X3000 supports DirectX 9.0 with vertex and pixel Shader Model 3.0 features. The processor consists of different clock domains, meaning that the entire chip does not operate the same clock speed. This causes some difficulty when measuring peak throughput of its various functions. Further adding to

1656-524: The last product of Intel GMA . In a way, it belongs to the 4500MHD series, and it is used in the GM47 chipsets, Montevina . It features 80 shading units, 10 texture mapping units , and 1 ROPs. Compared to the 4500MHD, the frequency is increased to 640 MHz. Intel developed a new set of low power graphics architecture based on PowerVR . The available Linux drivers do not support much of this. The Intel SCH (System Controller Hub; codenamed Poulsbo ) for

1702-483: The low-performing S3 ViRGE , the latest GMA generation should ease many of those concerns for the casual gamer. Despite similarities, Intel's main series of GMA Integrated Graphics Processors (IGPs) is not based on the PowerVR technology Intel licensed from Imagination Technologies. Intel used the low-power PowerVR MBX designs in chipsets supporting their XScale platform, and since the sale of XScale in 2006 has licensed

They were commonly found on netbooks , low-priced laptops and desktop computers , as well as business computers which do not need high levels of graphics capability. In early 2007, about 90% of all PC motherboards sold had an integrated GPU . The GMA line of GPUs replaces

1794-519: The original source. Besides, vendors using the GCC stack within IDEs must use separate tools to index the code, to provide features like syntax highlighting and intelligent code completion . Clang retains more information during the compiling process than GCC, and preserves the overall form of the original code, making it easier to map errors back into the original source. Clang's error reports are more detailed, specific, and machine-readable, so IDEs can index

1840-521: The similar vertex shader technologies. Like previous Intel integrated graphics parts, the GMA 900 has hardware support for MPEG-2 motion compensation , color-space conversion and DirectDraw overlay. The processor uses different separate clock generators for display and render cores. The display unit includes a 400 MHz RAMDAC , two 25–200 Mpixel/s serial DVO ports, and two display controllers. In mobile chipsets, up to two 18-bit 25–112 MHz LVDS transmitters are included. The GMA 950

1932-510: The toolchain as a whole. It supports most of the commonly used GCC options. A Fortran project, Flang was in-progress in 2022. However, for other languages, such as Ada , LLVM remains dependent on GCC or another compiler front end. The Flang project by Nvidia and The Portland Group adds Fortran support. Flang is LLVM's Fortran frontend. It is often referred to as "LLVM Flang" to differentiate itself from "Classic Flang" – these are two separate and independent Fortran compilers. "LLVM Flang"

1978-575: The upcoming C++23 standard. Since v16.0.0, Clang compiles C++ using the GNU++17 dialect by default, which includes features from the C++17 standard and conforming GNU extensions. In 2005, Apple Inc. made extensive use of LLVM in several commercial products, including the iOS SDK and Xcode 3.1. An OpenGL code compiler for OS X that converts OpenGL calls into more fundamental calls for graphics processing units (GPU) that do not support certain features,

2024-593: Was "substantially redesigned" when compared to previous GMA iterations and it is used in the Intel G965 north bridge controller. The GMA X3000 was launched in July 2006. The GMA X3000's underlying 3D rendering hardware is organized as a unified shader processor consisting of 8 scalar execution units. Each pipeline can process video, vertex, or texture operations. A central scheduler dynamically dispatches threads to pipeline resources, to maximize rendering throughput (and decrease

2070-453: Was one of the first uses of LLVM. This enabled Apple to support OpenGL on computers using Intel GMA chipsets, increasing performance on those machines. The LLVM project originally intended to use GCC 's front end. The GCC source code, however, is large and somewhat cumbersome; as one long-time GCC developer put it referring to LLVM, "Trying to make the hippo dance is not really a lot of fun". Besides, Apple software uses Objective-C , which

2116-1057: Was the second graphics core produced under Intel's Graphics Media Accelerator product name, and was incorporated in the Intel 945G chipsets . The processor includes an up to 400 MHz 256-bit core, supporting up to 10.6 GB/s memory bandwidth with DDR2-667 system RAM, up to 224 MB max. video memory through DVMT scheme, 1.6 GPixels/s and 1.6 GTexels/s fill rate, a max. resolution of 2048x1536 for both analog and digital displays, 2 SDVO ports for flat-panels and/or TV-Out via ADD2 cards or media expansion cards. 3D-wise, GMA 950 supports up to four pixels per clock rendering, Microsoft DirectX 9.0 hardware acceleration & Vertex shader 3.0 and OpenGL 1.4 with ARB extensions on Windows.
