基于CPLD的UART设计

The design of UART on the basis of CPLD

介绍了运用CPLD,实现ISA总线的通用并行I/O端口与C8051的UART通信。本文对UART接口电路的内部结构和CPLD实现做了介绍,所设计的UART接口电路经过了实际的运用,达到了预定的功能。

It introduces that it is possible to use Universal Parallel I/O Port of ISA bus and UART of C8051 in communication on the use of CPLD. In this paper it gives a reference to make the intemal contexture of interface circuit and CPLD carry into effect, furthermore, the designed interface circuit achieve predicted function through use in practice.
