Study on Hardware Compression System Architecture for RBC Algorithm

VL SI architecture based on the RBC algorithm is developed. The architecture is fastwith low hardware complexity,which can compute huge amount of data at very high speed for real- time compression application and match the requirement of VL SI architecture,regularity,modularity,locality.Based on the architecture,special chip for real- time image compression is designed and manufactured with Field Programmable Gate Array.The peak processing speed of the ASIC can reach2 88Mbit/s and their power consumption is lower than1W.
