Abstract
A system, method and product for providing data compression and decompression. A method is disclosed that includes: utilizing a CPU to perform a matching-bytes search, byte-oriented search result coding, and content analysis on a set of raw data to generate a set of initially compressed data; forwarding the set of initially compressed data from the CPU to a hardware accelerator; utilizing the hardware accelerator to perform search result re-coding, table construction, and encoding to generate a set of further compressed data; and forwarding the set of further compressed data back to the CPU.
