Member Data Documentation
◆ counter
| SatCounter32 gem5::compression::FrequentValues::VFTEntry::counter |
The ideal counter width (in bits) is determined by the maximum number of times a given value appears in the cache (log2(cache_size / chunkSizeBits)).
If smaller counters are used their values should be rescaled when saturated.
Definition at line 129 of file frequent_values.hh.
Referenced by invalidate(), and gem5::compression::FrequentValues::sampleValues().
◆ value
| uint64_t gem5::compression::FrequentValues::VFTEntry::value |
The value is stored as a 64 bit entry to accomodate for the uncompressed value.
All real values must be 32 bits.
