简介: Interface chip is a chip with an interface circuit that has the following functions: (1) Set the data storage and buffer logic to adapt to the speed difference between CPU and peripherals. The interface is usually composed of some registers or RAM chips. If the chips are large enough, batch data transmission can be realized.(2) Conversion of information format, such as serial and parallel conversion;(3) can coordinate the CPU and peripherals in the type of information and level differences, such
