MRU2this technology requires an additional clock cycle for register operations to rename registers. 4. Dedicated register A dedicated memory is usually a set of status registers that cannot be changed by a program and is controlled by the CPU itself to indicate a certain state. (2) Controller The arithmetic unit can only perform calculations, while the controller is used to control the entire CPU's operation. 1. Instruction controller The instruction controller is a very important part of the controller, which needs to complete operations such as fetching and analyzing instructions, and then hand them over to the execution unit (ALU or FPU) to execute, while also forming the address of the next instruction. 2. Timing controller The function of a timing controller is to provide control signals in chronological order for each instruction. The timing controller includes a clock generator and frequency doubling definition Among them, the clock generator emits a very stable pulse signal from a quartz crystal oscillator, which is the main frequency of the CPU; And the frequency doubling definition unit It defines how many times the CPU main frequency is the memory frequency (bus frequency). 3. Bus controller The bus controller is mainly used to control the internal and external buses of the CPU, including address buses, data buses, control buses, and so on. 4. Interrupt controller The interrupt controller is used to control various interrupt requests and queue them one by one based on their priority level CPU processing. 1. The function of the CPU controller is to analyze instructions and issue corresponding control signals. The CPU includes operational logic components, register components, and control components. 2. The Central Processing Unit, also known as the CPU, is a computing and control core of a computer introduced in 1971. It is the ultimate execution unit for information processing and program execution. The CPU includes operational logic components, register components, and control components, and has functions such as processing instructions, executing operations, controlling time, and processing data. Since its inception, it has made significant progress in logical structure, operational efficiency, and functional extension. Register components, including general-purpose registers, specialized registers, and control registers. General purpose registers can also be divided into fixed point and floating point numbers, which are used to store register operands temporarily stored during instruction execution and intermediate (or final) operation results. Universal registers are an important component of the central processing unit, and most instructions need to access them. The width of a general-purpose register determines the width of the data path inside a computer, and the number of ports can often affect the parallelism of internal operations. The main functions of the CPU are sequence control, operation control, time control, and data processing. 1. Sequential control: This refers to the execution order of instructions in the control program. There is a strict order between the instructions in the program, and it is necessary to strictly follow the sequence specified in the program to ensure the correctness of computer operation. 2. Operational control: The function of an instruction is often achieved by a series of operations performed by components in a computer. The CPU needs to generate corresponding operation control signals based on the function of the instructions, send them to the corresponding components, and control these components to act according to the requirements of the instructions. 3. Time control: Time control is the implementation of timing for various operations. During the execution of an instruction, there should be strict control over what operations are performed at any time. Only in this way can computers work systematically and automatically. 4. Data processing: refers to performing arithmetic and logical operations on data, or performing other information processing. Extension materials: CPU (Central Processing Unit), also known as the central processing unit. Today, with the emergence and development of CPUs, due to the increasingly advanced manufacturing technology, their integration is becoming higher and higher, with the number of internal transistors reaching several million. Although the number of transistors has increased dozens of times since the initial development of CPU, the internal structure of CPU can still be divided into three parts: control unit, logic unit and storage unit. The performance of the CPU roughly reflects the performance of the microcomputer it is configured with, so the performance indicators of the CPU are very important. CPU performance mainly depends on its main frequency and work efficiency. 1. Processing Instructions Processing instructions in English refer to the order in which instructions are executed in a control program. There is a strict order between the instructions in the program, and it is necessary to strictly follow the sequence specified in the program to ensure the correctness of computer system operation. 2. Execute Action The function of an instruction is often achieved by a series of operations performed by components in a computer. The CPU needs to generate corresponding operation control signals based on the function of the instructions, send them to the corresponding components, and control these components to act according to the requirements of the instructions. 3. Control time Control time in English refers to the timing of various operations. During the execution of an instruction, there should be strict control over what operations are performed at any time. Only in this way can computers work in an orderly manner. 4. Processing data That is, performing arithmetic and logical operations on data, or performing other information processing. Its main function is to interpret computer instructions, process data in computer software, and execute instructions. Extension materials: The Role of CPU The internal structure of cpu can be divided into control unit, logical unit and storage unit. The working principle of a CPU is like the processing of products in a factory: the raw materials (instructions) entering the factory are dispatched and distributed by the material distribution department (control unit), and then sent to the production line (logical computing unit). After producing the finished product (processed data), it is stored in the warehouse (storage) and finally waiting to be sold on the market (for application use). As the core of the entire microcomputer system, CPU is often synonymous with various grades of microcomputers, such as 286, 386, 486 in the past, and now Pentium,
