基于CPLD的单片机接口电路设计

MCU Interface Design Based on CPLD

介绍了一个用Xilinx公司XC9500系列可编程逻辑器件设计的单片机接口、显示电路。简单叙述了利用Vrilog-HDL硬件描述语言和Xilinx ISE5.x设计工具软件,完成单片机接口、显示电路的设计过程,并给出了原程序代码和使用ISE WehPACK对显示电路仿真的波形和接口电路综合结果,以及有关技术资料所在网站的网址。

This paper introduces an interface and display circuit of MCU using the programmable logic device of Xilinx Company's XC9500 series. The designing procedure is also described by using Verilog-HDL hardware description language with Xilinx ISE 5.2 designing tools. The simulation waves and synthetic result of source program are shown, and the web addresses about the CPLD/FPGA technique are given.
