Abstract

With compressed bit streams, more configuration information can be stored using the same memory. The access delay is also reduced, because less bits need to be transferred through the memory interface. To measure the efficiency of bit stream compression, compression ratio (CR) is widely used as a metric. it is a major challenge to develop an efficient compression technique that can significantly reduce the bit stream size without sacrificing the decompression performance. Our approach combines the advantages of previous compression techniques with good compression ratio and those with fast decompression. This paper makes three important contributions. First, it performs smart placement of compressed bit streams to enable fast decompression of variable-length coding. Next, it selects bitmask-based compression parameters suitable for bit stream compression. Finally, it efficiently combines run length encoding and bitmask-based compression to obtain better compression and faster decompression.
