Description: In this paper, based on FPGA computer and interface experimental platform design issues, first of all, this article on the FPGA-based computer and interface experimental platform design issues, first described the core board design. On the basis of FPGA, the programmable counter/timer 8253 and the programmable parallel controller 8255 are taken as examples, and the 8255 and 8253 interface chips are introduced. The functions of 8255 and 8253 are designed in VHDL language. Finally, on the ModelSim SE development software To achieve the compiler, debugging,
