Design and Implementation of a High Speed Data Channel Link Port Between DSPs on Different Board

A high speed data channel Link port between DSPs (TMS320C641X)on different board is proposed and implemented. By adopting the LVDS(low voltage differential signaling) protocol the transport speed of Link port arrive at 2.4Gbit/s. Using the Link port, TMS320C641X have strong transport capability and is used to constitute multi-DSP system of one dimension or multi-dimension network easily. The topologic of multi-system can be changed online to meet the variability of the parallel algorithm of image processing.
