Abstract: A system includes a compression engine that stores the compression format information embedded in the compressed data. The compression format information can be included in a header that includes compression control surface (CCS) information. The system includes a shared memory to store compressed data for multiple hardware pipelines, where blocks of the compressed data have a common memory footprint and the compression header. The compression engine can compress data to store in the shared memory including generation of the header. The compression engine can decompress data read from the shared memory, including identification of the compression format from the header.

Abstract: A graphics processor includes multiple levels of memory units, including a memory device and a cache device located near a graphics component. The graphics processor includes distributed compression/decompression, including a module between the cache device and the memory device. The module can perform compression of write data when the write data is moved from the cache device to the memory device, and perform decompression of read data when the read data is moved from the memory device to the cache device. The graphics processor can include a second level of cache with another compression module between the first level of cache and the second level of cache.
