Motherboard problems of AMD chipset

Edit the development history of AMD desktop platform in this section.

Since its establishment, AMD has continuously developed new products and gradually formed a unique corporate culture. Many employees have made great achievements in their careers. The following will briefly introduce the development process of AMD in the past 30 years, from which we can foresee the bright future of the company.

AMD has a long history and outstanding achievements. This tradition has become a cohesive force that closely unites AMD's global employees. AMD was founded in 1969. At that time, the company was very small, and even its headquarters was located in the home of a founder. But since then, AMD has been developing continuously, and now it has become a multinational company with an annual income of $2.4 billion. The following will introduce the important events that determine the development direction of AMD and the main forces that push AMD forward, and review the major events of AMD in chronological order.

1969-74- looking for opportunities

May 6th is a very important day for Jerry Sanders. In the months before that, he and seven other partners had been trying to create a new company. Jerry resigned as the global marketing director of Fairchild Semiconductor last year. At the moment, he is leading a team to work hard. The goal of this team is very clear-to build a successful semiconductor company by providing increasingly sophisticated building blocks for manufacturers of electronic products such as computers, communication equipment and meters.

Although at the beginning of the company, all employees could only work in the living room of JohnCarey, one of the founders, they soon moved to Santa Clara, California, and rented two rooms behind a carpet shop as office locations. By September of that year, AMD had raised the necessary funds to start production and moved to 90 1 Thompson Place in Sunnyvale, California, which was AMD's first permanent office.

In the early days, AMD's main business was to redesign products for other companies, improve their speed and efficiency, and provide these products to the market as "second suppliers". AMD's slogan at that time was "better parameter performance". In order to strengthen the sales advantage of products, the company provides unprecedented quality assurance in the industry-all products are produced and tested according to strict MIL-STD-883 standards, and the relevant guarantees are applicable to all customers without any additional fees.

By the fifth anniversary of its establishment, AMD had 65,438+0,500 employees and produced more than 200 different products, many of which were developed by AMD itself, with annual sales of nearly $26.5 million.

1980- 1983- Pursuing Excellence

In the early 1980s, two famous signs represented the situation of AMD. The first is the so-called "asparagus era", which represents the company's determination to increase the number of patented products it provides to the market. It takes a long time to develop a patented product like this high-profit crop, but it will eventually bring satisfactory returns to the initial investment. The second sign is a huge wave. AMD regards it as the core symbol of "following the trend" recruitment activities, and represents the irresistible force in the field of integrated circuits with this wave.

We are truly unstoppable. AMD's investment in R&D has always been ahead of other manufacturers in the industry. By the end of 198 1 fiscal year, the company's sales more than doubled compared with 1979 fiscal year. During this period, AMD expanded its factory and production base, and focused on building new production facilities in Texas. AMD established a new production base in San Antonio and expanded its factory in Austin. AMD has quickly become an important competitor in the global semiconductor market.

AMD celebrated its15th anniversary with the best annual sales performance in the company's history. A few months after AMD celebrated its anniversary, employees received a record profit dividend check and celebrated Christmas with Chicago from Los Angeles and Joe King carrasco and Krone from Texas.

But by 1986, the wave of change began to sweep the whole industry. Japanese semiconductor manufacturers have gradually occupied a dominant position in the memory market, which has always been the main pillar of AMD business. At the same time, the severe economic recession has hit the whole computer market, limiting people's demand for various chips. AMD and other companies in the semiconductor industry are committed to finding new means of competition in an increasingly difficult market environment.

By 1989, Jerry Sanders began to consider reform: restructuring the whole company in order to win a competitive advantage in the new market. AMD began to strengthen its sub-micron manufacturing capability by establishing sub-micron R&D centers.

AMD's development in this period is mainly achieved by providing more and more competitive products, continuously developing manufacturing and processing technologies that are crucial for mass production, and strengthening cooperation with strategic partners. During this period, the cooperation with infrastructure, software, technology and OEM partners is very important, which enables AMD to lead the whole industry to develop into innovative platforms and products and re-introduce market competition.

1995, AMD and NexGen met for the first time and discussed a common dream: to create a series of microprocessors that can re-introduce market competition. These talks prompted AMD to acquire NexGen in 1996 and successfully launch AMD-K6 processor. AMD-K6 processor not only achieved these high-starting goals, but also served as a bridge to help AMD launch its next-generation AMD Athlon processor series. This marks the real success of the company.

The successful listing of 1999 AMD Athlon processor indicates that AMD has finally achieved its goal: to design and produce an industry-leading, self-developed processor compatible with Microsoft Windows. AMD introduced an industry-leading processor for the first time, which can use chipsets and motherboards optimized for AMD processors. AMD Athlon processor will continue to create many new records for the company and the whole industry, including the first processor with a historical frequency of 1GHz( 1000MHz), which makes it one of the most famous processor products in the history of industry development. AMD Athlon processors and systems based on AMD Athlon processors have won more than 100 prestigious awards from many independent publications and organizations around the world.

While launching this innovative product series, the company also has sufficient production capacity to meet the growing market demand for its products. 1995, Fab 25 in Austin, Texas was successfully built. Before Fab 25 was built, AMD was fully prepared to build its next large-scale production base in Dresden, Germany. The strategic cooperation with Motorola enables AMD to develop future-oriented processor technology based on copper interconnection, thus making AMD the first company to develop a processor compatible with Microsoft Windows by using copper interconnection technology. This jointly developed processing technology will help AMD to stably produce a large number of AMD Athlon processors in Fab 30.

In order to find new means of competition, AMD put forward the concept of "sphere of influence". For reforming AMD, these ranges refer to microprocessors, network and communication chips, programmable logic devices and high-performance memories compatible with IBM computers. In addition, the company's lasting vitality also comes from its success in the development of sub-micron processing technology. This technology will meet the production needs of the company in the next century.

On the occasion of its 25th anniversary, AMD has used all its advantages to achieve these goals. At present, AMD ranks first or second in all markets it participates in, including Microsoft Windows? Compatible market. The company has successfully overcome the legal obstacles in this respect and can produce self-developed and widely used Am386 and Am486 microprocessors. AMD has become an important supplier of flash memory, EPROM, network, telecommunications and programmable logic chips, and is committed to establishing another mass production base specializing in sub-micron equipment. In the past three years, the company has achieved record sales and operating income.

Although AMD's image is very different from that of 25 years ago, it is still a tenacious and firm competitor as always, and can overcome any challenge through the unremitting efforts of employees.

AMD continues to maintain its leading position in the field of flash memory technology by providing industry standards for dual-operation flash memory devices. Flash memory has become an important part of many technologies, which promoted the technological prosperity at that time. Mobile phones and the Internet have increased the market demand for flash memory, and its application is becoming more and more common. AMD's extensive product line of flash memory devices can meet the memory requirements of mobile phones, car navigation systems, Internet devices, cable TV set-top boxes, cable modems and many other applications.

Through various flash memory and microprocessor products that can provide customers with obvious competitive advantages, stable production of a large number of products, industry-leading global production bases, and future-oriented and competitive products and manufacturing plans, AMD can successfully enter the new century after successfully surviving the prosperity period.

AMD (ATI) A Brief History of AMD (ATI) Graphics Processing Field1On August 20th, 985, ATI Company was established. He and two other Hong Kong immigrants, Benny Lau and Lee Lau, co-founded Array Technology Industry, also known as ATI Company.

1986, ATI got the first order and was booked with 7000 chips every week. At the end of that year, ATI earned 10 million dollars.

At the end of 1980s and the beginning of 1990s, ATI's turnover almost reached $ 1 billion, ranking among the top 50 high-tech companies in Canada.

199 1 year, ATI company introduced the first graphics accelerator card-mach 8. This graphics accelerator card has on-board and independent versions, which can display graphics independently of CPU.

1992 ATI introduced Mach32A, which is an improved version of Mach8.

1993, ATI was listed on the Toronto Stock Exchange after its annual turnover exceeded 230 million Canadian dollars. Later, due to the stock market crash, ATI once faced a situation of life and death. After Mach64 was born, all ATI's troubles were solved with its success. ATI began to set up its own 3D department, which laid the foundation for later ATI.

1994, the first graphics card Mach64 was born, which can provide acceleration function for images. This graphics card is a milestone in the history of computer graphics development. Mach64 adopts Graphics Xpression and Graphics Pro Turbo technologies, which can support the color space conversion from YUV to RGB, and enable PC to gain the video acceleration capability of MPEG.

Mach64-VT version was born in 1995. Fully bear the burden of CPU decompression. Because the VT version of Mach64 provides the ability to filter the X-axis and Y-axis in the video, when the video image with the resolution of 320x240 is adjusted to 1024x768, there will be no mosaic caused by enlargement.

1996 65438+ 10, ATI launched the 3D Rage series. Start to provide decoding support for MPEG-2. Later, advanced technologies such as iDCT of Rage series display chips were introduced, which greatly reduced the burden on CPU when playing MPEG-2 video.

1997 released 3D Rage Pro in April. With the filling rate of 45 million pixels and the material compression function of VQ,1.2000 triangles, 8MBSGRAM or 16 MBW RAM can be generated at high speed per second, which brought great pressure to the voodoo, the king of 3D graphics chips at that time.

1997, Tseng Labs, a very powerful company in the 2D era, was acquired by ATI, and 40 experienced graphic engineers joined ATI's development team.

1Feb. 998, Rage Pro was renamed Rage Pro Turbo, and the driver was updated accordingly, and the performance was improved by nearly 40%.

1998, rage 128 GL released. Rage 128 GL is the first hardware in Quake 3 to support OpenGL extension set.

1999 In April, ATI released Rage128 Pro, the final product of RAGE series. Anisotropic filtering, optimized polygon setting engine and higher clock frequency make Rage 128 Pro the official designated graphics card of 1999 QuakeCon, and the higher-end RAGE Fury Pro adds Rage Theater to improve the video performance of the graphics card.

1999, ATI managed two Rage 128 Pro chips with AFR technology, * * * participated in 3D operation, that is, the graphics card RAGE Fury MAXX had two display chips, Leona. Fury MAXX became the ancestor of single-card dual-core, and also had a certain impact on the future dual-card or multi-card parallel technology.

1999, ATI went public on NASDAQ and began to calculate its value in US dollars.

In April 2000, the 6th generation graphics chip Radeon256 of ATI was born. It supports DDR-T&, bandwidth-saving HyperZ technology, complete T&L hardware support, Dot3, environment mapping and bump mapping, and uses a unique hardware architecture of two pipelines and three material mapping units (TMU) in a single pipeline. Due to the special architecture, the third drawing unit did not have any program to support it until Radeon256 was removed. Radeon256' s rendering pipeline is so powerful that it can even perform programmable shading calculation.

In 200 1 year, ATI introduced a new generation of chip R200. R200 fully supports Microsoft DX8. 1 and SM 1.4, and uses RIP map to filter anisotropy. The new HyperZII technology saves bandwidth, and the advanced video immersion II technology and dual-head display provide high-quality video services. TRUFORM technology smoothes the corners of the triangle, making the picture smoother, better in quality and more accurate in full-screen anti-aliasing beautification.

In February, 2002, ATI acquired ArtX Company during the transition from R200 to R300, and sold its designed "Flipper" to Nintendo as the display chip of its game machine "GameCube". Although it cost 400 million yuan, this merger can be said to be the most cost-effective transaction of ATI. The greatest help to ATI is to bring a skilled, mature and stable technical team to help ATI complete the design of R300 and pave the way for the glory of R300.

In August 2002, the most legendary R300 core in the history of ATI graphics chips came out. ATI made a big bet on the future, betting all his money on Microsoft DX9. R300 uses new technology to double the number of transistors, but the frequency is very high. The most special hardware architecture is that the ratio of pixel rendering pipeline to TMU is 1: 1, and eight rendering pipelines form an advanced hardware architecture of 8x 1. R300 Advanced Interleaved Memory Controller brings a bus width of 256 bits and provides a memory bandwidth of nearly 20g/s. Each of the four advanced fixed-point coloring units can perform vector and scalar operations at the same time. Advanced SSAA and MSAA antialiasing modes are introduced, with the highest anisotropic filtering performance of 16X, fully supporting DX9 hardware specification, ultra-long instruction set and ultra-long constant register, fully supporting 24-bit floating-point precision specified by MRT and DX9, and so on. R300 became the most advanced and powerful display chip at that time. Compared with the rival flagship GF4ti4600 at that time, the performance of R300 exceeded 15~20%, while the advantages of AA and AF were expanded to 40%~ 100%. NVIDIA was caught off guard, and the quickly launched NV30 still adopted a conservative 4x2 architecture because it misjudged the timing of the DX9 game boom. Although it introduced quite a few new functions, it didn't have a chance to play at all, and it was losing ground in front of R300 and DX9 games. I just saved a little face in OpenGL games in the past.

In February, 2003, ATI introduced the overclocked version R300, named R350 and R360, which still succeeded in the market.

In May 2004, ATI R420 (R400) was released. ATI's new generation display chip R420 is very similar to R300 in architecture. Dual R300 pixel rendering resources, 16 pixel rendering pipeline, 16 raster processor, increase PS instruction length, strengthen F-Buffer management, and support PCI-E 16X. One of the biggest features is the normal map compression technology named 3Dc, which uses RGB or RGBA format to compress the normal map to 4: 1 without losing a lot of picture information. ATI insists that it is not time to update to SM3.0, so R420 only supports SM2.0+ technical specifications. While CF crossfire imitates NVIDIA's dual-card parallel SLI technology. Under the initial immature drive, the performance of dual-card parallel in the game is not much improved.

June 5438+October 2005 10, ATI released R520. Just like R420, there are only 16 rendering pipelines. With polar thread scheduling processor, R520 can handle up to 5 12 threads at the same time, and the advanced thread management mechanism greatly improves the efficiency of each rendering pipeline. Eight vertex coloring units with SM3.0 are introduced to support dynamic flow control instructions, and R2VB is adopted to bypass the provisions of SM3.0 on VTF. The adoption of 256-bit ring bus increases the memory delay, but it is flexible in data scheduling. Support FP32 and HDR+AA；; ; Advanced Avivo technology makes the video quality of ATI products reach a new level. ATI thinks that future games will need more shaders, so the ratio of pixel shading unit to TMU should be larger. So R580 uses 48 3D+ 1D pixel coloring units, but uses the same 16TMU as R520. This peculiar 3: 1 architecture has been proved to be superior to the traditional 1: 1 architecture in new games with tight PS resources such as Need for Speed 10 and The Elder Scrolls 4. Fetch4, an advanced soft shadow filtering technology, makes R580 more efficient in dealing with shadows.

On July 24th, 2006, AMD officially announced the acquisition of ATI. 10 in cash and stock, with a total value of $5.4 billion. 1On October 25th, AMD announced that the acquisition of ATI has been completed, and ATI has become history as an independent brand. AMD has also become the first company in the history of PC development that can provide CPU, GPU and chipset at the same time, which is a milestone in the history of PC development.

In 2007, AMD released the R600 kernel. Inheriting ATI's tradition of attaching importance to video playback ability, all products of R600 series have built-in 5. 1 channel audio chips, which transmit audio and video signals through HDMI interface. Like G80, R600 is a hardware design that fully supports DX 10. There are 64 US***320SP, and the floating-point operation ability reaches 475GFLOPS, which greatly exceeds the level of G80 345GFLOPS. The 5 12 bit loopback bus provides a larger display bandwidth for the chip. Adopt a brand-new UVD video scheme, support hardware decoding of VC- 1 and AVC/H.264, and fully support HDMI audio and video output of Vista. Through DVI——HDMI interface, 5. 1 surround sound audio and HDTV video signals can be output at the same time.

In August 2008, AMD released the R700 kernel. SIMD array is expanded to 10 group, which is 2.5 times of the original RV670, and the number of stream processors is also increased from 320 to 800. Moreover, each group of SIMD is bound with its own cache and texture units, and the capacity of registers is also increased, and the texture units are correspondingly increased to 10 groups, reaching a total of 40. In addition, the full-screen anti-aliasing ability of RV770 is greatly enhanced. RV770 still maintains four groups of post-processing units, namely 16 ROPs (grating unit), but AMD redesigned the internal structure of grating unit to improve the anti-aliasing performance of weak AA. R00/670 includes 8 Z template samples in each post-processing unit, while RV770 increases to 16 samples, so its multiple sampling (MSAA) speed can be almost twice as fast as before. Of course, the anti-aliasing algorithm of RV770 will eventually be handled by Shader, and the 800 stream processors of RV770 can just come in handy, and the anti-aliasing performance will be greatly improved. RV770 can easily break through the floating-point operation ability of 1 flop by relying on the processing power of 800 stream processors. Becoming the first GPU core to successfully reach 1 flop is a landmark breakthrough in the history of graphics cards. And built-in second generation UVD video decoding engine. Compared with the first generation UVD technology, it has been improved in the following aspects. 1. better supports ultra-high bit rate video coding and playback. 2. Support 2 160P and higher resolution video coding. 3. Support multi-stream decoding, that is, multiple HD movies can be decoded at the same time, which is more powerful than the dual-stream decoding realized by NVIDIA on GTX280. 4. Continue to build high-definition audio module, and output 7. 1 channel AC3 and DTS encoded audio streams through HDMI interface. In terms of technology, AMD(ATI) is the first in the industry to adopt the GPU core with 55nm manufacturing technology, which can reduce the wafer cost and control the cost. At the same time, the thermal power consumption design of 55nm process is better than the previous graphics card, which can effectively reduce the calorific value and improve the overclocking ability. Finally, RV770 supports DirectX 10. 1. DX 10. 1 improves the access function of shader resources and reduces the performance loss in multi-sampling antialiasing. It can also improve the shadow filtering efficiency of the new game and further improve the light and shadow effect. In addition, DX 10. 1 also supports 32-bit floating-point filtering, which can improve rendering accuracy and HDR image quality.
