| Abstract: | In order to improve the multi-processor communication speed in multi-processor control system of high-speed data acquisition based on DSP such as Electrical jacquard detector, the paper presents the design of hardware circuit of 5402 HPI and computer parallel ports communication, and software design as well. Based on the integrated enhanced 8-bit HPI on -chip peripheral of TMS320VC5402DSP, the new design can realize the high-speed communication without any additional handshake protocol. The scheme has been used in Electrical jacquard detector and has been found to have a good effect. |
