Abstract
Techniques are disclosed for designing cache compression algorithms that control how data in caches are compressed. The techniques generate a custom 'byte select algorithm' by applying repeated transforms applied to an initial compression algorithm until a set of suitability criteria is met. The suitability criteria include that the 'cost' is below a threshold and that a metadata constraint is met. The “cost” is the number of blocks that can be compressed by an algorithm as compared with the “ideal” algorithm. The metadata constraint is the number of bits required for metadata.
