Question

C) A set-associative cache consists of 64 lines, or slots, divided into four-line sets. Mainmemorycontains 4K blocks of 128 words each. Show the format of main memoryaddresses. (Subject: Computer Archetecture)

Expert Solution

Step 1

Main memory size

= 4K* 128 words

= 4K * 128 * 4B

= 2¹² * 2⁷ * 2²

= 2²¹ bytes

Or main memory bits is 21 bits

Step by step
