摘　　要：HPI是德州仪器公司新一代，高性能DSP上配置的与主机进行通信的片内外设。介绍了TMS320C5402的HPI口在DSPs中的应用，并给出了具体的硬件连接和部分程序代码。该方案以简单的电路设计实现了5～DSPs系统稳定高速的数据传输。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.
