Abstract
A method and apparatus for real time compressing randomly accessed data includes extracting a block of randomly accessed data from a memory hierarchy. One or more individual portions of the randomly accessed data are independently compressed in real time to create a lossless compressed image surface. The compressed image surface includes data of independently compressed image blocks for reading and decompressing in a random order. The method further includes storing structured information relating to the dynamically compressed randomly accessed data.
