Abstract
A code compression method and apparatus for system-level power optimization that lessens the requirements imposed on main memory size. The apparatus utilizes a post-cache architecture that has a decompression engine that decompresses compressed object code instructions using dictionary look-up tables, branching instruction controllers and mathematical derivations based on bit toggling. The decompression engine extracts the compressed instructions from memory or the instruction/data cache using a bus compression technique to save power as the compressed instructions/data traverses the bus.
