Row substitution when missing in group-linked cachefully-connected cacheA fully-connected cache consists of a group (e=c/b) that contains all the high-speed slowdown.Basic structure:1. Group selection in the fully-connected cacheThere's only one group, so it's simple.2. Line matching and word selection in fully-connecte
