Abstract

- We have made a performance and energy exploration of a previously proposed dictionary code compression mechanism where frequently executed individual instructions and/or sequences are replaced in memory with short code words. Our simulated design shows a dramatically reduced instruction memory access frequency leading to a performance improvement for small instruction cache sizes and to significantly reduced energy consumption in the instruction fetch path. We have evaluated the performance and energy implications of three architectural parameters: branch prediction accuracy, instruction cache size and organization. To asses the complexity of the design we have implemented the critical stages in VHDL.
