摘要
为实现高速双向并行I/O总线通信,以双机架构设计通信控制接口,基于互锁中断控制机制,采用主动请求方式进行双向的命令和数据传输。介绍和分析了有关的设计方案、硬件构成和软件流程。实际运行结果表明,具有硬件电路简单可靠、控制方便灵活、通信数据不易丢失的优点。
With dual MCU structure on interlock interrupt mechanism, the main design including hardware solution and software scheme of the parallel I/O communication controller are proposed and discussed in detail. The actual run results indicated that it has advantages of reliability and efficiency for credible communication
