What's the use of single-chip computer C language?

Single chip microcomputer refers to a complete computer system integrated on one chip. Although most of its functions are integrated on a small chip, it has most of the components needed by a complete computer: CPU, memory, internal and external bus systems, and most of them will have external memory at present. At the same time, peripheral devices such as communication interface, timer and real-time clock are integrated. Nowadays, the most powerful single-chip microcomputer system can even integrate sound, image, network and complex input and output systems on one chip. Single chip microcomputer is also called microcontroller because it was first used in the field of industrial control. Single-chip microcomputer is developed from a special processor with only CPU in the chip. The earliest design concept was to integrate a large number of peripheral devices and CPU into one chip, making the computer system smaller and easier to integrate into complex and strict control equipment. Intel's Z80 is the first processor designed according to this idea. Since then, the development of single chip microcomputer and special processor has gone their separate ways. Single-chip microcomputer is more suitable for embedded system than special processor, so it has been used the most. In fact, single-chip microcomputer is the largest number of computers in the world. Almost every electronic and mechanical product used in modern human life will be integrated with a single microcomputer. Cell phones, telephones, calculators, household appliances, electronic toys, palmtop computers and mice are all equipped with 1-2 single-chip computers. And there will be many single-chip computers working in personal computers. Cars are generally equipped with more than 40 single-chip computers, and there may even be hundreds of single-chip computers working at the same time in complex industrial control systems! The number of single-chip computers not only far exceeds the sum of PC and other calculations, but also exceeds the number of human beings. At present, single-chip microcomputer has penetrated into every field of our lives, and it is almost difficult to find out which field has no trace of single-chip microcomputer. Missile navigation device, control of various instruments on the plane, computer network communication and data transmission, real-time control and data processing of industrial automation process, various intelligent IC cards widely used, safety guarantee system of luxury cars for civilian use, control of video recorders, video cameras and automatic washing machines, as well as program-controlled toys and electronic pets. , are inseparable from the single chip microcomputer. Not to mention robots, intelligent instruments and medical devices in the field of automatic control. Therefore, the research, development and application of single chip microcomputer will bring up a group of scientists and engineers in computer application and intelligent control.
