What is the overall speedup? 2. [6 points] Assume a 2way set associative write-back cache with many cache entries that starts empty. Following is a sequence of five memory operations: Write Mem[0x140]; Write Mem[0x184]; Read Mem[0x142]; Write Mem[0x14C]; Write Mem[0x170]. With C-16KB and b-32W. and 32b address line. a) What is the hit rate when using no-write allocate cache? b) What is the size of the tag array? c) How to improve hit rate without increasing cache size?
