given this series of address references given as word addresses: 5, 6, 14, 19, 24, 16, 67, 51, 22, 14, 6, 25, 7, 30, 9, and 14. assume a direct map cache with 16 one-word blocks that is initially empty, a. label each reference in the list as hit or miss? b. show the final contents of the cache? c. show the hits and misses and final cache contents for a fully associative cache with four-word blocks and a total size of 16 words using the series of references given. assume lru replacement.

Answer :

Using the R mod w operation, where k is the number of blocks and n is the total number of blocks, every block number is kept in the cache.

M in the location references signify Mus and H indicate Hit-

last satisfied of the store is 48, 2, 3, 4,21,6 11, 13.

for the reference steuings 0, 1, 16, and 32, there is a miss for all references in cache C1. There is a hit for "1," but there is a miss for all other references in cache C2.

Because O is referred to for the first time in words when C2 is used to cache 02. 0,1,2,3 are brought in. As a result, the miss rate of C1 for the reference string above is 1009, or 4/4 = 1. miss rate of C2 is 3/4, or 75%. C1 used 84 -32 memory bus clock cycles, while C2 used 11 +3 memory clock cycles, or 33.
