Abstract�� Aim at the characteristics of embedded image matching, TMS320C6X family processo rs were used for parallel neural computing units, and a multi-processo r system structure based on TMS320C6X HPI(host parasite interface) interlinkin g for neural network image matching was presented. In this parallel computing sy stem, one host computer and three DSP neural units are contained, the master com puter is directly linked with each neural computing unit by HPI, memory of each neural unit can be directly accessed by the master computer through their HPI, t he real time image datum and the inter-results datum of each neural unit can be immediately directed transmit to each other between neural unit and the master c omputer. As a result, the real time performance of image matching is effectively improved according to theoretical analysis.
Keywords�� image matching   artificial neural network   multi-processor   HPI(host port inte rface)
