摘要
介绍了DSP(Digital signal processor)芯片TMS 320VC 5402的HPI(Host port interface)主机接口原理,以一个简单的通信程序作为例子,详细说明通过HPI口实现5402芯片内部的16 kB双端口RAM与AT 89 C 51单片机的通信过程.采用C语言与汇编语言混合编程的方式,实现了双端口通信.
Principle of the host port interface of TMS320VC5402 was introduced and 16 kB dual port RAM of TMS320VC5402 communicated with AT89 C51 single chip computer by HPI was discussed in detail taking a simple communicating procedure as an example. The dual port communication was realized successfully by means of C language and compile language combining programming.
