Problem 6.6(p. 490) Fundamental parameters Parameter Description Number of sets E Number of lines per set B=2b Block size(bytes m=log2(M) Number of physical (main memory)address bits Derived quantities Parameter Description M=2 Maximum number of unique memory addresses Number of set index bits b=log2(B) Number of block offset bits =m-(8+b) Number of tag bits C=BXEX S Cache size(bytes)not including overhead such as the valid and tag bitsProblem 6.6 (p.490) • The table gives the parameters for a number of different caches. For each cache, determine the number of cache sets(S), tag bits(t), set index bits(s), and block offset bits(b). Cache m C B E S t s b 1. 32 1024 4 1 2. 32 1024 8 4 3. 32 1024 32 32
