An architecture for victim cache
Srinivasan Subha · 2016
Victim caches enable the direct mapped and fully associative modules during cache operation. This paper proposes model to reduce power consumption in victim caches with improved performance. The model introduces the setnumber variable per fully associative cache block indicating the set to which the block belongs in the direct mapped cache module of victim cache. An address is checked for the setnumber match in fully associative cache before address matching. The number of block comparisons in fully associative cache is reduced. Power saving of 69% with performance improvement of 5% is observed for simulations on SPEC2K benchmarks.
