1 .Using the access time information given in the Figure , calculate average memory accesstime AMATa . With only LI cache*AMAT = tcache1 + MRcache 1 ( TMM )b . With only LI and LZ cacheAMAT = tcache 1 + MR cache 1 [ * cache2 + MR cache2 ( tMM ) ]C . With all three LI , LZ , and L 3 cache levelsAMAT = tcache1 + MR cache 1{ tcache2 + MRcache2 [ t caches + MR cache3 ( tMM ) ] ]Assume miss rate for L 1 is 10% , for L 2 is 1% and for L3 is 0. 1 % .
