A processor is a feature that interprets and executes instructions. Each processor has a unique set of operations such as ADD, STORE, or LOAD, which is the instruction set of the processor. Computer system designers are accustomed to refer to computers as machines, so the instruction system is sometimes called the machine instruction system, and the binary language in which they are written is called machine language. Note: Do not use the processor's instruction system with advanced BASIC or PASCAL. The instructions in the programming language are confusing—the instructions consist of opcodes and operands, the opcodes indicate the operational functions to be completed, and the operands represent the objects of the operation.
For example, if an instruction is to perform a two-digit addition operation, it must know: 1. What are the two numbers? 2. Where are these two numbers? When these two numbers are stored in the computer's memory, there should be an address indicating their location, so if the operand represents data in the computer's memory, the operand is called the address.
The job of the processor is to find the instructions and operands from memory and perform each operation. After completing these tasks, the memory is notified to send the next instruction. The processor repeats this step-by-step operation over and over again at an alarming rate. A timer called a clock accurately issues a timing electrical signal that provides a regular pulse for processor operation. The term measuring computer speed is taken from the field of electrical engineering, called megahertz (MHz), and megahertz means millions of cycles per second.
For example, a normal clock ticks every second, while in an 8MHz processor, the computer's clock ticks 8 million times. The processor consists of two functional components (control components and arithmetic logic components) and a set of special workspaces called registers. A control component is a functional component that is responsible for supervising the operation of the entire computer system. In some respects it is similar to a smart phone switch because it links the various functional components of the computer system and controls each component to complete its operation according to the needs of the currently executing program. The control unit fetches instructions from memory and determines their type or decodes them, and then decomposes each instruction into a series of simple, small steps or actions. In this way, the entire computer system can be controlled to operate step by step.
An Arithmetic Component (ALU) is a functional component that provides logic and computing power to a computer. The control component sends the data to the arithmetic logic component, which then performs the arithmetic or logical operations required to execute the instruction. Arithmetic operations include addition, subtraction, multiplication, and division. The logical operation completes the comparison and selects an operation based on the result, for example, comparing whether the two numbers are equal, and if they are equal, continuing processing; if not, stopping processing.
A register is a memory location inside the processor. The registers in the control unit are used to keep track of the overall status of the running program. It stores information such as the current instruction, the address of the next instruction to be executed, and the operand of the current instruction. In the arithmetic logic component, the register stores data items to be added, subtracted, multiplied, divided, and compared, while other registers store the results of arithmetic and logic operations. An important factor affecting processor speed and performance is the size of the registers. The term size (also known as word length) describes the size of the operand register, but it can also be used to describe the size of the channel into and out of the processor less strictly. Today, general-purpose computers typically have a word length of 8 to 64 bits. If the processor's operand register is 16 bits, then the processor is said to be a 16-bit processor.
The instruction code digital computer is a general purpose digital system. A general purpose digital computer can perform various micro-operations and can also specify which specific sequence of operations it must perform. The user of the system can control the processing through a program, which is a set of instructions that specify operations, opcodes, and execution processing sequences. Data processing tasks can be easily changed by writing new programs for different instructions or by entering different data for the same instructions. The computer's instructions are binary code that specifies the sequence of computer micro-ops. The instruction code is stored in the memory along with the data. The controller reads each instruction from memory and stores it in a control register, which then interprets the binary code of the fetch instruction and completes the instruction by issuing a series of control operations. Each general purpose computer has its own proprietary command system. The ability to store and execute instructions (the concept of a stored program) is the most important feature of a general purpose computer. The “working frequency” is also called “main frequency”. The higher the frequency, the faster the execution speed of the instruction, the shorter the execution time of the instruction, and the higher the processing power and efficiency of the information. What I want to say to beginners here is that the operating frequency of the processor does not completely determine its working performance. The design method, operating environment, etc. are all important factors for performance. The central processing unit, or simply the processor, is abbreviated as CPU, which is Central Processing Unit, which is one of the main devices of electronic computer (Hong Kong translation - electronic calculator). Its function is mainly to interpret computer instructions and process data in computer software. . The CPU provides basic digital computing features for electronic computer design. CPUs, storage devices, and input/output devices are the three core components of modern microcomputers. A CPU fabricated from an integrated circuit is often referred to as a microprocessor.
