| Abstract: | HPI is an 8/16-bit parallel port used to interaface a host processor or device to the Texas In-struments(TI) tms320C54x digital signal processor(DSP). A method has been provided to realize the communication between two TMS320C5402 DSPs through its own 8-bit HPI, including hardware interface and accompanying software routine. The system of two DSPs could communicate with high and steady speed by the desing. |
