What are the CPU architectures?

CPU architecture refers to the new technology manufacturing adopted by CPU manufacturers, and generally new technologies are better than the old ones!

The CPU is the center of the problem, and the frequency of the CPU directly affects the speed of the computer to deal with the problem.

The quality of the base also determines the quality of the house.

To put it simply, it is the foundation of the CPU, which is related to the quality of the CPU, just like building a house, needless to say!!

CPU is a very large-scale integrated circuit, which is the computing core and control unit of a computer.

a) CPU architecture.

The CPU architecture is determined by the type and specifications of the CPU mounting socket. At present, commonly used CPUs can be divided into two architectures: Socket X and Slot X according to their installation socket specifications.

Taking Intel processors as an example, there are three types of CPUs in the Socket architecture: Socket 370, Socket 423, and Socket 478, which correspond to Intel PIII Celeron processors, P4 Socket 423 processors, and P4 Socket 478 processors, respectively. CPUs with slot X architecture can be divided into slot 1 and slot 2, which are installed using slot slots of the corresponding specifications. Slot 1 is the architecture adopted by earlier Intel PII, PII, and Celeron processors, and Slot 2 is a larger socket designed to install a CPU in the P and P sequences that is dedicated to workgroup servers.

To put it simply, the architecture of the CPU is similar to the layout of a factory, and a good layout can improve efficiency, just like an AMD dual-core processor based on the K8 architecture, with a clock speed and performance that is not as good as that of an Intel Core architecture dual-core processor.

In layman's terms, it is like what the overall structure of a building looks like...

CPU architecture is a specification set by CPU vendors for CPU products belonging to the same series, and the main purpose is to distinguish different types of CPUs.

**The processing unit (CPU) is mainly composed of three parts: combinator, controller and register, literally the combinator plays the role of operation, the controller is responsible for issuing the information required for each instruction of the CPU, and the register is to save some temporary files of the operation or instructions, which can ensure higher speed.

CPU architecture and encapsulation:

to Intel processors.

For example, there are three types of CPUs in the socket architecture: Socket 370, Socket 423, and Socket 478, corresponding to Intel PIII Celeron processors, P4 Socket 423 processors, and P4 Socket 478 processors, respectively. s

The CPU of the Lot X architecture can be divided into two types: slot 1 and slot 2, which are installed using the slot slots of the corresponding specifications.

Slot 1 is the architecture of the early Intel PII, PII, and Celeron processors, and Slot 2 is a larger socket designed to install CPUs in the P and P sequences that are dedicated to workgroup servers.

2) CPU packaging method The so-called packaging refers to the installation of the shell of the semiconductor integrated circuit chip, which is connected to the pins of the package shell with wires through the contacts on the chip, and these pins pass through the printed circuit board.

slots on to connect with other devices. It plays the role of mounting, fixing, sealing, protecting the chip and enhancing the electrical and thermal performance.

The CPU is packaged in the form of a single socket socket (PCA) and the CPU is packaged in the form of a single-sided socket (SEC) in the form of a single socket socket.

Processor architecture: A specification set by CPU vendors for CPU products that belong to the same series.

For example, Xiao Ming and Xiao Hong are CPU2 cores, there is a question that is 1 plus 1 plus 1, and one structure is that Xiao Ming makes 1 plus 1 equals 2, and hands it to Xiao Hong, and Xiao Hong makes 2 plus 1 equals 3. Another framework, Xiao Ming and Xiao Hong, study 1 plus 1 plus 1 together. There are also frameworks for Xiao Ming to do 1 plus 1 plus 1 by himself, and when he wants to calculate 2 times 3 times 4, change to Xiao Hong, who learns better, to do it, or do it together.

There are many frameworks, and the above is just a metaphor.

1. CPU architecture is the packaging form of CPU. One is socket and the other is slot.

2. The slot architecture has been defeated and eliminated, such as Intel's called Slot 1, AMD's called Slot architecture is currently the most common, such as Intel's socket370, socket478, socket T (also known as LGA775), AMD's socket462, socket754, socket939, socket940, etc.

3. CPU includes operation logic components, register trap components and control components, etc., English Logic Components; The arithmetic logic component can perform fixed-point or floating-point arithmetic operations, shift operations, and logical operations, as well as address operations and transformations.

Analysis: Explanation 1:

The form factor of the CPU. One is socket and the other is slot.

The slot architecture has been eliminated, and the representatives such as Intel's are called slot 1 and AMD's are called slot A.

Socket architecture is currently our most common, such as Intel's Socket 370, Socket 478, Socket T (also known as LGA775), AMD Socket 462, Socket754, Socket939, Socket940, etc.

Explanation 2: The internal structure of the CPU, including transistor circuit design, manufacturing process, instruction set, computing pipeline, bus operation...

For example, P is designed with the P6 bus architecture, which has the advantage of short pipeline and high execution efficiency, but the disadvantage is that the front-end bus is synchronized with the external frequency, and the bus bandwidth cannot meet the high-throughput data.

The advantage of this architecture is that it can use QDR technology to use 4 times the transmission rate to achieve high bandwidth and achieve high throughput requirements of data. The disadvantage is that although the ultra-long computing pipeline can increase the main frequency of the CPU, the ultra-long pipeline leads to the serious inefficiency of the CPU's execution, so people often describe the CPU of P4 as high-frequency and low-energy, and the high frequency leads to a serious increase in the power consumption and heat of the CPU, therefore, Intel has developed the core architecture.

The core architecture can be said to be the fastest desktop processor at present, it is similar to the P6 architecture, but it has a completely different concept from the P6 architecture: first of all, its biggest advantage is to shorten the pipeline, so that the computing efficiency of the CPU is greatly improved, and secondly, it retains the Netburst bus transmission mode, the bus is still 4 times the operation of the external frequency, and then uses the advanced technology of sharing the L2 cache, the performance of the CPU has been improved to a very high level. The advantages of this architecture are high computing efficiency and low power consumption, and the disadvantage is that the current ** is expensive...

I'm not very clear about AMD's architecture, so I'm not going to make any comments for now. But one thing is certain: AMD's bus architecture is not inferior to Intel's, because AMD uses a memory controller integrated into the CPU and operates in HTT bus mode, which alone means that AMD's CPU also has absolutely excellent performance.

A detailed explanation of the typical architecture types of CPUs.

The CPU is the core component of a computer, and its performance directly affects the speed and processing power of the computer. Different CPU architecture types can also affect the performance of your computer to a great extent. So, what are the typical architecture types of CPUs?

1.Von Neumann Architecture.

The von Neumann architecture is one of the most commonly used types of CPU architectures. It is characterized by placing programs and data in the same memory, the programs are executed sequentially, and each instruction is decoded and executed by the controller. The advantage of this type of architecture is that it is easy to understand, easy to implement, and scale, but there is also a bottleneck, which is the limitation of memory bandwidth and speed.

2.Harvard architecture.

The Harvard architecture is similar to the von Neumann architecture, but it separates the program memory from the data memory, and the program and data can be read at the same time. This has the advantage of increasing the data transfer speed, but it also increases the complexity due to the fact that the controller needs to access both the program and the data memory.

3.Enhanced Harvard architecture.

The enhanced Harvard architecture is a type of architecture that is optimized on the basis of the Harvard architecture. It achieves higher data throughput by adding some cache internally to optimize the read speed of programs and data. Compared with the Harvard architecture, the enhanced Harvard architecture is more complex, but its performance is also better.

4.Superscalar architecture.

Superscalar architecture is one of the most common types of CPU architecture in modern computers. It has multiple instruction units and multiple execution units, which can decode multiple instructions and execute them in parallel at the same time, so as to achieve higher performance. Compared with the traditional von Neumann architecture, the superscalar architecture is more flexible and efficient, but also has a higher complexity.

In short, different CPU architecture types have their own advantages and disadvantages and applicable scenarios, and choosing the right CPU architecture is very important to improve the performance and operation efficiency of your computer.
