| Abstract: | 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. |
