What is the role of the CPU of the computer and what is the role of the CPU of the computer?

The core of a computer is the CPU, the role of the CPU in the computer is equivalent to the brain of the whole computer, while carrying out all the data calculations, but also to manage and coordinate all the equipment, if the performance of the CPU is not enough, not only the speed of data calculation will slow down, but also affect the coordination between the system, and then affect the performance of the whole system. Therefore, with a powerful CPU, we can make our computer have higher performance. When buying a computer, it is important to choose a powerful CPU.

Performance is a comprehensive embodiment of various evaluation indicators of a product. As far as the CPU is concerned, performance is a comprehensive embodiment of its various technical indicators such as main frequency, frequency doubling, external frequency and bus technical indicators, which refers to the number of instruction sets executed per unit time. If it's just fast speed, but the overall coordination is not good, it's not a good CPU either.

In most cases, when we buy a CPU, we always pay attention to what the main frequency of the CPU is, and think that the higher the frequency of the CPU, the better the CPU performance. In fact, the main frequency does not determine the performance of the entire CPU. The main frequency of the CPU represents the internal current ** frequency of a CPU in actual operation, if the two CPUs are exactly the same design, then the higher the main frequency, the better the computing performance, this theory is correct; However, CPU products with different designs do not have to comply with this rule, such as:

AMD Athlon vs. Intel Pentium 4 In real-world testing, the performance of AMD Athlon CPUs is significantly higher than Intel Pentium 4 performance by 30%. This fully proves that there is no direct relationship between the clock speed and the performance. It also shows that AMD's CPUs can achieve high performance at the right clock thanks to their design advantages.

AMD has long been committed to producing high-performance CPUs that maximize investment protection that can bring maximum value to consumers, and its unique excellent design and strong performance have been loved by consumers.

The CPU is the brain of the computer, and all actions (reading, displaying, storage, etc.) need to be coordinated and commanded by the CPU.

The heart of the computer, responsible for processing and computing.

**Processor.

All instructions need to go through the CPU.

The CPU is the basic thing inside the computer. How good or bad it is has a direct impact on the performance of your computer.

It works the same way as your large and small brains.

It should be about the same as the human heart, buy a computer book and read it.

Hello, according to your description, simply put, the computer CPU is similar to the human brain, responsible for the overall deployment work, the general name of the CPU is **processor. , which is the combinator and controller of the computer.

The internal structure of the CPU can be roughly divided into several main parts, such as the control unit, the computing unit, the storage unit and the clock.

1. Processing instructions: This refers to the order of execution of instructions in the control program. There is a strict order between the instructions in the program, and the computer system can only be guaranteed by executing them in strict accordance with the order specified in the program.

Correctness of work.

2. Perform operations: The function of an instruction is often realized by a series of operations performed by the components in the computer. According to the function of the instruction, the CPU should generate the corresponding operation control signal and send it to the corresponding components, and then control these components to act according to the requirements of the instruction.

3. Control time: the implementation of time timing for various operations. In the process of executing an instruction, what to do at what time should be strictly controlled, so that the computer can work in an orderly manner.

4. Processing data: that is, performing arithmetic and logical operations on data.

or other processing. Its function is mainly to interpret computer instructions and process data in computer software, and to execute instructions. All operations of the computer are controlled by the CPU, and the performance indicators of the CPU directly determine the performance indicators of the microcomputer system.

The role of the CPU in a computer is one of the main devices of an electronic computer. Its function is mainly to interpret computer instructions and process data in computer software. The so-called programmability of a computer mainly refers to the programming of the CPU.

The CPU is the core component of the computer, but it is the computing core and control core of a computer.

Under the action of crystal oscillator, it constantly converts the program pointer to mobilize other parts of the computer to work together, fully proving that it is the brain of the computer.

Responsible for the most important computing tasks of the whole computer.

In computer architecture, CPU is the core hardware unit that controls and allocates all hardware resources (such as memory, input and output units) of a computer and performs general-purpose operations. It is the computing and control core of the computer. All the software layer operations of a computer system are ultimately mapped to the operations of the CPU through the instruction set, and the function is mainly to interpret computer instructions and process data in computer software.

For CPUs, the main indicators that affect its performance are the main frequency, the number of bits of the CPU, and the cache instruction set of the CPU. The so-called CPU frequency refers to the clock frequency, which directly determines the performance of the CPU, so in order to improve the performance of the CPU, it is a good way to increase the frequency of the CPU. The number of bits of the CPU refers to the number of bits of floating-point number that the processor can calculate at one time, and in general, the higher the number of bits of the CPU, the faster the CPU will be able to perform calculations.

**Processor function: the core hardware unit that controls the provisioning and executes general-purpose operations; It is the computing and control core of the computer.

**The processor is referred to as CPU, which is the computing core and control core of a computer launched in 1971, and is the final execution unit of information processing and program operation. The CPU contains arithmetic logic components, register components, and control components, and has functions such as processing instructions, performing operations, controlling time, and processing data. Since its inception, it has made great progress in logical structure, operational efficiency and functional extension.

The CPU is the processor, including the combinator and the controller, which is responsible for the running of the program.

It's like the human brain. The CPU is the processor. Operation. The heart of the computer.

The processing center, which is approximately equivalent to the human brain, does not contain memory functions.

What is CPU? CPU is an abbreviation, the full name is Central Processing Unit, ** processor, is the computer responsible for processing data and computing components. Every action you do needs to go through its calculations before it can show you the results.

The CPU is in English "Central."

processing

The abbreviation of "unit", the CPU is generally composed of a logical operation unit, a control unit and a storage unit. In the logical operation and control unit includes some registers, these registers are used for the temporary storage of data in the process of processing data in the CPU, in fact, when we buy the CPU, we do not need to know its structure, as long as we know its performance.

The main performance indicators of the CPU are:

The main frequency is the clock frequency of the CPU (CPU

clockspeed)。This is what we are most concerned about, what we mean by etc., generally speaking, the higher the frequency, the faster the speed of the CPU, and the higher the whole machine.

The clock frequency is the external clock frequency of the CPU, which is provided by the computer motherboard, which used to be generally 66MHz, and there are also motherboards that support 75 each 83MHz, and the latest chipset BX of Intel uses a clock frequency of 100MHz. In addition, some non-Intel chipsets such as MVP3 and MVP4 of VIA have also begun to support 100MHz external frequency. Elite BX motherboards can even support a 133MHz external frequency, which is a top choice for overclockers.

Internal cache (l1

Cache): The cache enclosed inside the CPU chip, used to temporarily store part of the instructions and data during CPU operation, the access speed is consistent with the CPU frequency, the capacity unit of L1 cache is generally the larger the cache, the less the CPU works and the L2 cache with slower access speed and the memory The fewer times the data is exchanged, and the computing speed of the computer can be improved.

External cache (l2

Cache): Cache outside the CPU, Pentium

The Pro processor's L2 and CPU run at the same frequency, but the cost is expensive, so Pentium

The II runs at half the CPU frequency and has a capacity of 512K. In order to reduce costs, Inter has produced a CPU without L2 called Celeron, which also has good performance and is ideal for overclocking.

MMX technology is an abbreviation for "Multi-Extended Instruction Set". MMX was launched by Intel in 1996 for the enhancement of the Pentium

New technologies adopted by CPUs for audio-visual, graphics, and communication applications. Add 57 MMX instructions to the CPU, in addition to adding MMX instructions to the instruction set, the L1 cache in the CPU chip is increased from the original 16KB to 32KB (16K command + 16K data), so MMX

Compared with ordinary CPUs, the ability of the CPU to process more than 10 more than ordinary CPUs when running programs containing MMX instructions is about 60%. At present, CPUs basically have MMX technology, except for P55C and Pentium

CPUs also have K6 and K6

3D, MII, etc.

Manufacturing process: The manufacturing process of CPU is micron now, the latest PII can reach micron, and in the future CPU manufacturing process can reach micron.

CPU manufacturer.

The CPU acts like the human brain.
