Design And Realization Of CPU Nucleus And Virtual Platform Based On FPGA

The research topic is consigned to us by YuShun electronics technology limited company from Southeast University.The highly development of science and technology brings about the naissance and fast development of computer. In modern society, the application areas of the computer almost come down to all fields of human society, which makes the research and development of the computer never be interrupted. For this reason, on the basis of existing inner structure of the computer, an experiment platform for computer learning is developed via the software and hardware design of three big modules of the system. This platform offer a intuitionistic way to learn the inner construction of the computer for users and the users design their own computer model in terms of the users' demands. It has excellent practicability.This dissertation gives a design scheme and simulation as well as realization course of computer module in detail by adopting FPGA technique. The system design in the dissertation includes three big modules as following:1. The centre processing module of computer: it adopts the FPGA chip of Altera Company and its integrate software MAXPLUSII to design the CPU nucleus with full function;2. The memory and data transmission module: on the one hand it sets up the gateway with the CPU nucleus according to designed logic, and on the other hand, it encapsulates RAM and ROM modules and sets up the gateway with the epigynous PC.3. The virtual platform module: it designs a model machine platform by using VB software technique according to the CPU structure and realizes the software database's Real-time data scan transmission and display with hardware PFGA chip .All the circuit designs are downloaded to the FPGA chip to be testified, and they successfully connect the display software of the computer, and good test results are obtained.
