Avoid multi-core bandwidth bottleneck AMD Super Transmission design breakthrough

AMD (Advanced Micro Devices's English abbreviation, ultra-Granville Semiconductor annotation: Advanced for advanced, Micro for the small meaning of the English literal translation for the Advanced micro-semiconductors, but AMD for its own Chinese name is the ultra-Wei Semiconductor, so also known as micro-semiconductors Used here is the official statement) was founded in 1969, headquartered in California State Sunnyvale. AMD specializes in the design and manufacture of innovative microprocessors, Flash and Low-power processor solutions for the computer, communications and consumer electronics industries. AMD is committed to providing standards-based, customer-centric solutions for technology users-from businesses, government agencies to individual consumers. Its share in the CPU market is second only to Intel.

AMD has a global presence in the United States, China, Germany, Japan, Malaysia, Singapore and Thailand with manufacturing plants, and has sales offices in major cities around the world with over 16,000 employees. AMD sold 5 billion dollars in 2004. More than 70% of AMD's revenue comes from the international market and is a real multinational. The company is listed on the New York Stock Exchange, code-named AMD.

AMD's embedded solutions are targeted for Internet-connected devices other than PCs, with targeted products including tablets, car navigation and entertainment systems, home and small office networking products, and communications equipment. The AMD geode™ Solution Series includes not only embedded processors based on x86, but also a variety of system solutions. AMD's range of alchemy™ solutions include Low-power, high-performance mips™ processors, wireless technology, development boards, and reference design kits. With the introduction of these new solutions, AMD products will be more diversified, helping to establish AMD in the next generation of product market leadership position.

In order to ensure that the company's products continue to maintain its competitive edge, AMD has been committed to invest in the development of future generations of advanced technology. AMD is now developing high-performance technologies that can be applied over the next 5-10 years. At present, AMD is located in the United States Sunnyvale (Sunnyvale) and Germany Dresden (Dresden) Advanced technology Research and Development Center, respectively, responsible for a number of research and development projects. In addition, AMD is working with IBM to develop a new generation of technology.

ASUS Computer recently announced the launch of its first dual core Opteron processor with AMD server TW510-E2, and Taiwan's other server manufacturers Acer also earlier in Europe, the same dual-core Opteron processor Altos G5350 Vertical New machine, Therefore, with the Taiwan industry to join, and there are HP, IBM, Sun is quite the premise, resulting in AMD dual core server lineup momentum gradually Yang.

AMD's server and workstation product manager Brent Kirby first of all Intel processor architecture weaknesses-too dependent on the FSB (Front-side bus)-cannon, "their traditional FSB architecture is now the biggest function is to hinder its progress." We have yet to see any progress in this regard, and the old-style architecture of this front-end bus has been in use for more than 20 years. "Kirby refers to the fact that, as the number of processor cores increases, the problem of competing for resources and bottlenecks will only become more and more serious because more threads are making requests for both the output port and the memory."

It is reported that AMD's dual core processor, the two core embedded integrated into a silicon die, not like Intel mining " Dual Core Single Package "design method, it can avoid the problem of transmission bottleneck between different cores, plus its low power consumption, and in the main engine board PWM power module or radiator, and other parts, no need to replace or redesign, so the system manufacturers or even users, can shape a small inducement; therefore, under the Opteron, also will amd in the global x86 server market occupancy rate, from this year Q 1 of the 7.4% escorts to Q2 's 11.2%, the first to surpass the 10% mark.

The concept of "dual-core", which has recently become hot, mainly refers to dual-core technology based on X86 open architecture. In this regard, the leading manufacturers are mainly AMD and Intel two. Among them, the two ideas are different. AMD has been designing from the outset to take into account the support of multiple cores. All components are directly connected to the CPU, eliminating system architecture challenges and bottlenecks. The two processor cores are directly connected to the same kernel, and the core is communicated with the chip speed, further reducing the latency between the processors. Intel uses multiple cores to share the front-end bus. Experts believe that AMD's architecture for more easy to achieve dual-core and multi-core, Intel's architecture will encounter multiple kernel contention bus resource bottlenecks.
