Hello, Patrick, DictionaryCompressor<T>::CompData contains the patterns (in general, any compressor's "CompData" structure contains the compressed data, not the original data - there are some exceptions). The patterns, due to the deterministic nature of cache compressors, must always be able to successfully recreate the original cache line through a call to the compressor's decompress(const CompressionData* comp_data, uint64_t* data). We do not actively use the decompression step on regular simulation because it would be extremely costly, but it should be fairly straightforward to generate the original cache line from the compressed data. You can find out how you'd call the decompress function by doing an approach similar to what is done in Compressor::Base::compress(const uint64_t* data, Cycles& comp_lat, Cycles& decomp_lat), in src/mem/cache/compressors/base.cc. Regards, Daniel
