摘要
利用CPLD芯片实现单片机与ISA总线接口之间的高速并行通信 ,给出系统的总体设计方法及程序框图。采用这种通信方式 ,在 1 2MHz晶振的MCS5 1单片机控制的数据采集系统中 ,可以满足与PC1 0 4ISA总线接口实时通信的要求 ,通信速率达 2 0 0kbit/s。在开发工具MAX +plusⅡ下 ,完成了整个设计的输入、编译和仿真 ,达到了预期效果。本设计方案能够推广应用到计算机的高速并行通信中。
The solution of high speed communication between MCU and ISA bus is designed based on Altera CPLD. The system block and program code are also given in this paper. The communication can be created between MCS51 I/O systems in this way. They are finished in development tool MAX+plusII. This design can be widely used in the high speed communication between computer systems.
