Consider the characteristics of a memory system given below. Cache size 512 bytes Main memory size- 4096 bytes Cache line/block size- 64 bytes Replacement policy least recently used Write policy write-back Assume the cache is initially "empty" meaning that no cache blocks are considered valid at the start of the program. Assume a program to be executed on this system generates the following sequence of main memory byte addresses: 0 (Read), 512 (Write), 130 (Write), 800 (Write), 60 (Reac 1024 (Write). What is the best possible hit rate for this sequence of addresses? (5 points)
