摘　　要：为解决TMS320C6000系列DSPs的异步串行通信能力,提出一种新的解决方案,即利用多通道缓冲串行接口(McBSPs)与专用串行异步收发器来扩展异步串行接口.其硬件电路及软件编程简单、方便,可节省程序代码空间和CPU运行时间,是一种使用广泛的串行总线接口标准.通过对应用系统的配置,可支持多种速率和多种方式的SPI,可以方便地用于各种不同的SPI设备.In order to solve the capacity for TMS320C6000's UART communication,a new scheme was presented for expanding UART interface by using multi channel buffered serial ports and dedicated chip of asynchronous communications transceiver . And its hardware circuit and software programming are simple and convenient, so it can economize program code space and CPU running time.It is a sort of standard of serial bus interface used widely. Through configuration of the application system, it can support serial peripheral interface (SPI), which comprises various kinds of speeds and modes, and can be used for all kinds of SPI equipment conveniently.
