TMS320C6000系列DSP与PC机串行通信

Serial Communication Between TMS320C6000 DSP and Personal Computer

TMS320C6000系列DSP只提供同步串行接口,并不支持通用异步串行收发器标准,故其与微机及其它设备进行串行通信时,必须在DSP上扩展异步串行接口。以美国TI公司TMS320C6711 DSP为例,实现了几种与PC机串行通信的软硬件方案,并对各种方法的优点和缺点进行了比较。

TMS320C6000 digital signal processors only supply synchronous serial ports,and don＇t interface directly to a universal asynchronous receiver/transmitter （UART）. In order to communicate with personal computer and other devices,we must expand DSP into an asynchronous port. Take TMS320C6711 of Texas Instruments company for instance, several methods to realize serial communication between digital signal processor and personal computer, including both the hardware and software, are described in the paper. The advantages and disadvantages of each method are also discussed and compared.
