71 Reducing the memory bandwidth requirement for a multi-standard video codec by lossless compression of video using a combination of 2D-DPCM and Variable Length Coding

摘要

Memory bandwidth is a critical issue tor a high performance and high resolution video codec. We propose a lossless compression solution to reduce memory bandwidth requirement for a multi-standard video codec. The solution is a combination of 2D-DPCM, Variable Length Coding and 4-way set-associative cache. Experimental results show that the proposed solution can reduce the memory bandwidth requirement with 71% for reference data.
