摘　　要：本文提出了一种基于CPLD的双向并行通信接口,这种接口设计简单明了,可以解决两主机之间传输速率不一致问题,实现了可靠实时的数据传输。文中以实现MC51单片机与ISA总线接口的双向并行通信为例,具体阐述了这种双向通信接口的设计原理。A bi-directional communication interface between two hosts based on CP LD is presented in this paper. The interface is simple and efficient, and can so lve the problem of data rate mismatch between two hosts for stable data transmis sion. The design principle is discussed in detail through an example that realiz es bi-directional communication between MCU and the ISA bus.
