What is the cpu architecture? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Cpu architecture is a specification given by CPU manufacturers to CPU products belonging to the same series, and its main purpose is to distinguish important marks for different types of CPU. At present, CPU classification is mainly divided into two camps, one is the complex instruction set CPU headed by intel and AMD, and the other is the reduced instruction set CPU headed by IBM and ARM.

CPU architecture is a specification set by CPU manufacturers for CPU products belonging to the same series, and its main purpose is to distinguish important marks for different types of CPU. At present, the CPU classification in the market is mainly divided into two camps, one is the complex instruction set CPU headed by intel and AMD, and the other is the reduced instruction set CPU headed by IBM and ARM. The architectures of the products of two different brands of CPU are also different. For example, CPU of Intel and AMD is X86 architecture, while CPU of IBM company is PowerPC architecture, and ARM company is ARM architecture.

Overall architecture

Merom processors based on Core architecture do have strong performance. In many tests, the T7200 of the frequency 2GHz can beat the T2700 of the frequency 2.33GHz is the best proof. But you have also noticed that although the performance of Merom on mobile platform is strong, it does not bring you much surprise. Although it is better than Yonah, the range is not big, and in some test items, the T7200 with lower frequency also lost to T2700. Therefore, the advantage of core micro-architecture on mobile platform may not be as outstanding as that of desktop platform-an E6300 with the lowest frequency can also wipe out high-frequency Pentium D. The reason is that Yonah itself is better than NetBurst, and the Core micro-architecture itself is improved from the Yonah micro-architecture, and it is reasonable that the results will not form much contrast.

Core micro-architecture is a new generation of micro-architecture improved by Intel's Israeli design team based on Yonah micro-architecture. The most significant change lies in the strengthening of each key part. In order to improve the internal data exchange efficiency of the two cores, a shared secondary cache design is adopted, and the two cores share a secondary cache as high as 4MB. The kernel is designed with a short 14-level effective pipeline. Each core has built-in 32KB first-level instruction cache and 32KB first-level data cache, and data can be transferred directly between the two core first-level data buffers. Four instruction decoding units are built into each core, which supports microinstruction fusion and macro instruction fusion technology. Each clock cycle can decode up to five X86 instructions and has an improved branch prediction function. There are five execution unit subsystems built into each core, which has high execution efficiency. Add support for EM64T and SSE4 instruction sets. Because of the support for EM64T, it can have more memory addressing space, which makes up for the deficiency of Yonah. After the popularity of the new generation of memory-consuming Vista operating system, this advantage can make the core micro-architecture have a longer life cycle. And use Intel's latest five new technologies to improve performance and reduce power consumption, including: better power management; support for hardware virtualization technology and hardware anti-virus functions; built-in digital temperature sensor; provide power report and temperature report, etc. In particular, the adoption of these energy-saving technologies is of great significance to the mobile platform.

In addition, Core supports 64 bits.

Based on Core architecture processors in the face of different consumer groups, Core processors have a small division of labor, specifically for desktops using Conroe, notebooks using Merom, servers using WoodCrest, these three processors are all based on Core core architecture.

Intel processors, including Core series of desktop, mobile, and Xeon processors, and even embedded processors, will all enter the 32nm process one after another, gradually replacing the current 45nm process. As the CES approaches, Intel has revealed that it will release a number of Core i3 and i5 desktop and notebook processors on CES, including notebook Arrandale and desktop Clarkdale, with a 32nm process, emphasizing smaller size and power consumption. On December 23, 2009, Intel revealed that the embedded Xeon processor to be launched in the first quarter of 2010 will also adopt the new process. The 32nm process, which was put into production at the end of 2009, compared with the 45nm process at the end of 2008, uses the second generation high-k metal gate transistor and infiltrating Weiying technology (immersion lithography) to strengthen the internal control tube of the processor, which is also 30% smaller than the 45nm process size, simplifying system design. According to Intel's blueprint, in the first quarter of 2010, the embedded Xeon processor, codenamed Jasper Forest, will be launched for the embedded market, which provides 30 to 70 percent higher performance per watt than the older process processor and supports PCI 2.0 and Igamo virtualization capabilities. As for the enterprise server Xeon processor, with the introduction of the desktop processor Clarkdale in 2010, the entry-level Xeon 3000 processor, which is closely related to the high-end desktop market, will also enter a new 32nm process in 2009.

As for the Xeon 5000, which adopted the Nehalem-EP architecture in 2009, although it also uses the Nehalem architecture, it will introduce a new 32nm process and launch the Westmere-EP processor in the first half of 2010. The Xeon 7000 processor, which originally provided 6 cores, will also launch Nehalem-EX with up to 8 cores in the first half of 2010, and Westmere-EX, which will also enter the new process in the second half of 2010.

In addition to embedded systems, servers, laptops and desktops have entered the new process, only the low-power design of the Atom processor has not yet entered, still using 45 nm process.

Compared with Intel's new manufacturing process in 2010, AMD will start to enter the 32nm process in 2011, when it will adopt the new Bulldozer core architecture design, including Interlagos with energy levels 12 to 16 cores and Valencia with 6 to 8 cores with emphasis on energy efficiency.

The 8-core CPU now cannot correspond to the current motherboard, so it is impossible to publicize it with great fanfare. The cheapest 8-core CPU should be SONY PS3's CELL. The floating-point performance of 8 cores is more than N times that of Core double cores, but now 4 cores are not popular. AMD INTEL will not rush to mass-produce their 8-core CPU. It can be said that the current INTEL 4 cores only encapsulate two Core cores in one core. There is no direct communication between the two cores, but AMD has a true 4 core, but it is not selling well yet can not become the mainstream. To sum up, after 5 years, 4 cores can basically replace the current dual cores to become the mainstream, while 8 cores or even 16 cores CPU will become the high-end products at that time!

This is the end of the answer to the question about what is the cpu architecture. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
