Multiprocessor Expansion of DM642 Video Port
Wei Jiang, Jianling Hu · Jisuanji gongcheng · 2006
During image processing,a single DSP sometimes couldn’t meet the need of real-time,thus it is needed to use multiple DSPs to cooperation.According to the features of image signal and the principle of DM642 video port,the paper provides an available video port expansion based on multiprocessor.In the design,FPGA is used as preprocessing of digital video signal and realizes the flow-distribution of video data.In the mean time,FPGA provides the seamless connection with DM642 video port.The design greatly improves the DSP system’s throughput and concurrent processing abilities.It effectively solves the bottleneck during high-bandwidth application using DSP.
