基于硬件逻辑的微处理器通用开发系统的设计

A Design for Universal Research System of Microcontroller Based on CPLD

提出通过硬件逻辑芯片和加载不同的硬件逻辑配置软件,实现控制不同种类微处理器的相关功能管脚能够灵活映射连接到同一外围接口应用电路上。从而达到在不改变开发系统其他任何硬件结构的情况下实现微处理器型号的快速更换,解决了现存的对于不同微处理器需要设计不同开发实验系统的问题。

This Paper proposes a method which can map correlative function pins of different type microcontroller to same periphery interface applied circuit flexibly, by CPLD or FPGA and loading different configuration files. It can realize change different types of microprocessor quickly in the circumstances of no changing any hardware of the research system. It can solve the existent problem of different microprocessor needs corresponding research system.
