  1. Consider a cache of 4 lines of 16 bytes each. Main memory is divided into blocks of 16 bytes each. That is, block 0 has bytes with addresses 0 through 15, and so on. Now consider a program that accesses memory in the following sequence of addresses:
    1. Once: 63 through 70.
    2. Loop two times: 15 through 32; 80 through 95.

Suppose the cache is organized as two-​way set associative, with two sets of two lines each. Even-​numbered blocks are assigned to set 0 and odd-​numbered blocks are assigned to set 1. Compute the hit ratio for the two-​way set-​associative cache using the least recently used replacement scheme.

CASE Wyatt Earp - The Buffalo Hunter F. Robert Jacobs, Indiana University The legend of Wyatt Earp lives on largely based on his exploits as a gunfighter and Marshall of the frontier West in the 1880s. The classic tales of the shootout at the O.K. Corral in Tombstone or his sawed-off shotgun duel with Curly Bill are possibly the most celebrated gunfights of frontier history and cannot fail to stir the reader's imagination. Wyatt lived to be over 80 years...
