ABSTRACT:
In general, this disclosure describes techniques of storing data in and retrieving data from a cache of a computing device. More specifically, techniques are described for utilizing a “perfect hash” function to implement an associative cache within a computing device. That is, the associative cache implements a fully associative map between a predetermined set of addresses and data values, employing only a single tag fetch comparison.
