Public Attributes
uint64_t	value
	The value is stored as a 64 bit entry to accomodate for the uncompressed value.

SatCounter32	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)).

inline

Definition at line 132 of file frequent_values.hh.

void gem5::compression::FrequentValues::VFTEntry::invalidate ( )

inlineoverridevirtual

Invalidate the block.

Its contents are no longer valid.

Reimplemented from gem5::CacheEntry.

Definition at line 138 of file frequent_values.hh.

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 130 of file frequent_values.hh.

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.
