A study of CodePack
Avishay Orpaz, Shlomo Weiss · 2002
CodePack is a code compression system used by IBM in its PowerPC family of embedded processors. CodePack combines high compression capability along with fast and simple decoding hardware. IBM did not release much information about the design of the system and the influence of various design parameters on its performance. In our work we will present the system and its design parameters and investigate how each affects its performance on the compression rate and decoder complexity. We also present a novel efficient algorithm to optimize the class structure of the system.
