Abstract
A hybrid mechanism whereby hardware acceleration is combined with software such that the compression rate achieved is significantly increased while maintaining the original compression ratio (e.g., using full DHT and not SHT or an approximation). The compression acceleration mechanism is applicable to a hardware accelerator tightly coupled with the general purpose processor. The compression task is divided and parallelized between hardware and software wherein each compression task is split into two acceleration requests: a first request that performs SHT encoding using hardware acceleration and provides post-LZ frequency statistics; and a second request that performs SHT decoding and DHT encoding using the DHT generated in software.
