Abstract

Skewed caches have been proposed to reduce the miss ratio on a cache by indexing the cache lines of a two way set associative cache not with the index but with a hash function of the index and the tag. This paper proposes to use ECC codes as the hashing functions that allow also correcting the stored data. It is shown that ECC behave very well as hash functions and that ECC protection provides gains in terms of error coverage with respect to state of the art skewed cache approaches.
