Detailed Description

Definition of the Frequent Pattern Compression with limited Dictionary support (FPC-D) cache compressor, as described in "Opportunistic Compression for Direct-Mapped DRAM Caches", by Alameldeen et al.

It is a pattern compressor that can only have 2 dictionary entries, and as such the pattern encodings are specialized to inform to which entry it refers. These entries are replaced in a FIFO manner.
