The components formed by integrating the CPU on a chip are called microprocessors device.
Microprocessor is a central processing unit composed of one or a few large-scale integrated circuits. These circuits perform the functions of control components and arithmetic logic components.
The microprocessor can complete operations such as fetching instructions, executing instructions, and exchanging information with external memory and logic components. It is the computing control part of the microcomputer. It can be combined with memory and peripheral circuit chips to form a microcomputer.
Microprocessor (English: Microprocessor, abbreviation: µP or uP) is a programmable special integrated circuit. A processor in which all components are miniaturized into one or several integrated circuits. An integrated circuit that accepts encoded instructions at one or more of its terminals, executes the instructions, and outputs signals describing its status. These instructions can be entered, grouped or stored internally. Also known as the semiconductor central processing unit (CPU), it is a major component of the microcomputer. The components of a microprocessor are often mounted on a single chip or within the same component, but are sometimes distributed across a number of different chips. In a microcomputer with a fixed instruction set, the microprocessor consists of an arithmetic logic unit and a control logic unit. In a microcomputer with a microprogrammed instruction set, it contains additional control storage units [1]. When used to process general data, it is called a central processing unit. This is also the most well-known application (such as: AMD Ryzen CPU); dedicated to image data processing, called Graphics Processing Unit graphics processor (such as Nvidia GeForce 30X0 GPU); used for audio data processing, called Audio Processing Unit audio processing unit (such as Creative emu10k1 APU) and so on. From a physical perspective, it is a semiconductor integrated circuit chip that integrates a large number of micro-transistors and other electronic components.
It is called a microprocessor not only because it is smaller than the processor used in mini computers. The main difference is that the manufacturing processes of major chip factories have already entered the 1 micron scale stage. For processor chips produced at the micron scale, manufacturers will use the word "micro" in their product names to highlight their technology. As in many commercial advertisements nowadays, the word "nano" often appears.
Long before the advent of microprocessors, the central processing unit of electronic computers had gone through several important stages, from vacuum tubes to transistors and later to discrete TTL integrated circuits. Even before electronic computers, there were mechanical computers based on gears, axles, and levers. The famous Renaissance painter and scientist Leonardo da Vinci once made a similar design, but the backward manufacturing technology of that era simply did not have the ability to realize this design. The invention of the microprocessor allowed complex groups of circuits to be made into single electronic components.
Since the early 1970s, the improvement of microprocessor performance has basically followed the famous Moore's Law in the IT industry. This means that the computing power of CPUs has doubled every 18 months for more than 30 years. From supercomputers to notebook computers, microprocessors that continue to develop at a rapid pace have replaced many other forms of computing and become the source of computing power for all computer systems in various categories and fields.
