Computer Architecture: Memory and Cache, if your answer is not sure, please indicate NOT SURE Thanks

(Q1) If we have a direct-mapped cache with 32 blocks, where will the 16-bit memory address: 1101 1001 1000 1111 be stored in cache?

(a) In the block with address: 00111

(b) In the block with address: 00011

(c) In the block with address: 01111

(d) In the block with address: 11011

(Q2) A set-associative cache consists of 64 blocks, divided into four-block sets. How many valid bits we need per each block to validate the information stored inside? That is, how many valid bits does a block need to validate its contents?

(a) 2

(b) 8

(c) 1

(d) 4

Solution

In the block with address: 01111

Option c is correct choice.

8 valid bits does a block need to validate its contents

Option b is correct choice.
