Abstract
In accordance with various aspects of the invention, a recall transaction is issued if a tag filter entry needs to be freed up for an incoming transaction. Directory entries chosen for a recall transaction are pushed into a fully associative structure called victim buffer. If this structure gets full, then an entry is selected from entries inside the victim buffer for the recall.
Claims1
A system with cache coherence, the system comprising a victim buffer that includes:
- a push interface for output to address victim buffer directory entry storage structure;
- and
- a compress interface to compress around pointers if entry gets removed from the victim buffer due to at least one of a victim buffer hit and an update request.
Dependencies are inferred from the claim text.
