The present invention is based on bus (PCI bus and ISA bus), multi-platform (PC platform and embedded platform), multi-module (interface chip module and IO module) architecture, and it is mainly composed of bus bridge circuit, interface core circuit and peripheral circuit The area consists of three parts, the bus bridge circuit includes PCI to ISA interface, bridge chip, memory, power drive; the interface core circuit includes FPGA chip and 8253, 8255, 8252, 8279, 8259 interface chip; peripheral circuit includes LED and dial code Switch module, digital tube module, speaker module, stepper motor, DC motor, keyboard module, AD / DA module, clock module. The three components of the experimental platform are connected through the bus respectively. In addition to completing 16-bit or 32-bit microcomputer principles and interface technology course experiments, the present invention can also carry out interface chip logic design and function expansion experiments, and can be used for other course experiments, course design, professional training, graduation design and electronic competition.
