Abstract
A method and system for compressing and decompressing data is disclosed. A compression command may initiate the prefetching of first data, which may be stored in a first buffer. Multiple words of the first data may be read from the first buffer and used to generate a plurality of compressed packets, each of which includes a command specifying a type of packet. The compressed packets may be combined into a group and multiple groups may be combined and stored in a second buffer. A decompression command may initiate the prefetching of second data, which is stored in the first buffer. A portion of the second data may be read from the first buffer and used to generate a group of compressed packets. Multiple output words may be generated dependent upon the group of compressed packets.
