Function one: Reduce components

As we all know, on February 14, 1946, the computer ENIAC was born at the University of Pennsylvania, named ENIAC (ENIAC). The components at that time had a total of 18,800 vacuum tubes, 50 feet long and 30 feet wide, covering an area of 1,500 square feet, and weighing an even more exaggerated 30 tons. At that time, there was no integrated circuit at all, all were circuits composed of components one by one, and they were vacuum tubes. Later, the continuous progress of science and technology, the study of semiconductor components, thereby reducing the volume and weight of components, and then the study of integrated circuits, of course, is a small-scale integrated circuit, less content components, but compared with scattered components to say, there is still a great technological improvement. With the continuous improvement of technology and the continuous development of science and technology, the development of medium scale integrated circuit, large-scale integrated circuit, very large scale integrated circuit, etc., thus greatly reducing the number of scattered components.

Role two: Engage in high performance

Just like the computer mentioned above, it was running at 5,000 seconds. But there are tens or hundreds of times as many applications in computers today. The changing components are integrated together, which also reduces the interference of external signals, and the circuit design has also been greatly improved. This increases the speed of operation. This performance changes.

Function three: convenient application

In the circuit, in fact, there is a single function, just like in real life, advertising design will do advertising, programming will write programs. The same is true in the circuit, a function will correspond to a circuit, then a function can be concentrated into an integrated circuit, then in the future application, what function can be applied to the corresponding integrated circuit, which greatly facilitates the application. But now it's not just a function that's concentrated in an integrated block, it's a function that's concentrated in an integrated circuit.
