Abstract
Systems and methods compress and decompress 16 bit data. The 16 bit data may be signed or unsigned and represented in a fixed point or floating point format. A fixed block size of data is compressed into a fixed length format. Data compressed using a medium quality compression scheme may be efficiently decompressed in hardware. Data may be efficiently compressed and decompressed in hardware using a high quality compression scheme. The high quality compression scheme has a lower compression ratio compared with the medium quality compression scheme, but is near lossless in terms of quality.
