Member Function Documentation

◆ invalidate()

void gem5::prefetch::IndirectMemory::IndirectPatternDetectorEntry::invalidate ( )
inlineoverridevirtual

Invalidate the block.

Its contents are no longer valid.

Reimplemented from gem5::TaggedEntry.

Member Data Documentation

◆ baseAddr

std::vector<std::vector<Addr> > gem5::prefetch::IndirectMemory::IndirectPatternDetectorEntry::baseAddr

Potential BaseAddr candidates for each recorded miss.

The number of candidates per miss is determined by the number of elements in the shiftValues array.

◆ idx2

int64_t gem5::prefetch::IndirectMemory::IndirectPatternDetectorEntry::idx2

◆ numMisses

int gem5::prefetch::IndirectMemory::IndirectPatternDetectorEntry::numMisses

Number of misses currently recorded.
