This article is about what a microprocessor is in a microcomputer. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The development of the microcomputer is characterized by the development of the microprocessor, because the microprocessor is the core of all the activities of the computer, and the microprocessor can complete the operations such as fetching and executing instructions, and exchanging information with external memory and logic components, which is the operation control part of the microcomputer.

The development of microcomputers is characterized by the development of microprocessors.

Microprocessor is the core of all computer activities, so the development of microcomputer is characterized by the development of microprocessor.

A central processing unit consisting of one or a few large-scale integrated circuits. These circuits perform the functions of the control unit and the arithmetic logic unit.

The microprocessor can complete the operations such as fetching instructions, executing instructions, and exchanging information with external memory and logic components, so it is the operation control part of the microcomputer. It can form a microcomputer with memory and peripheral circuit chips.

Compared with the traditional CPU, the microprocessor has the advantages of small size, light weight and easy modularization. The basic components of the microprocessor are: register stack, arithmetic unit, timing control circuit, and data and address bus.

Since the invention of transistor in 1947, semiconductor technology has experienced several generations, such as silicon transistor, integrated circuit, very large-scale integrated circuit, very large-scale integrated circuit and so on. Semiconductor technology has an extensive impact on the whole society, so it is called "the seed of industry". Central processing unit (CPU) refers to the components in the computer that process data and control the processing process. With the rapid development of large-scale integrated circuit technology, the chip integration density is getting higher and higher. CPU can be integrated on a semiconductor chip. This kind of large-scale integrated circuit device with CPU function is called "microprocessor". It should be noted that the microprocessor itself is not equal to the microcomputer, but only the central processing unit of the microcomputer.

Microprocessors have been everywhere, whether video recorders, intelligent washing machines, mobile phones and other household appliances, or car engine control, as well as CNC machine tools, missile precision guidance and so on have to be embedded in all kinds of microprocessors. Microprocessor is not only the core component of microcomputer, but also the key component of all kinds of digital intelligent devices. International ultra-high-speed supercomputers, mainframe computers and other high-end computing systems are also built with a large number of general-purpose high-performance microprocessors.
