利用CPLD/FPGA技术加强单片机教学开发系统的研究

Research of Using CPLD/FPGA to Enhancethe MCU Teaching and Developing System

利用 CPL D内部强大的互连技术及在线可编程特性 ,实现单片机系统 I/ O的重新分配和外围硬件电路的设计。使单片机实验教学系统不仅能完成单片机软件设计与仿真 ;而且能实现单片机硬件电路的设计与仿真 ,将软件、硬件设计与仿真融为一体 。

This paper introduces how to implement the MCU I/O reconfiguration and peripheral circuit design based on CPLD/FPGA programming, and how to integrates the simulation of MCUs hardware and software. A mew developing system has been realized according to above idea, which can meet the demands of teaching MCU.
