摘要
目前大多数数字信号处理器(DSP)芯片上只提供2～3个同步串行接口,并不支持通用异步接口(UART)标准,其与微机及其它设备串行通信时,必须在DSP上扩展异步串行接口.针对DSP与PC机实时交换数据的通信接口标准不兼容的问题,以TMS320VC5402为例提出了一种串行通信设计方案,实现了DSP多通道缓冲串行口(McBSP)与PC机RS232接口的全双工通信.
At present, most of the DSP's provide only two or there synchronous ports and do not support UART. The UART, therefore, must be extended when DSP's communicate serially with PC and etc. Taking TMS320VC5402 as an example, a new design for serial communication is put forward in the light of the common problem of ports incompatibility in real time data exchanging between DSP and PC,and the full-duplex communication between McBSP and RS232 is realized.
