(1) Consider a computer with byte addressable main memory of 216 bytes and block size of 8 bytes. Assume that a direct mapped cache consisting of 32 lines is used with this computer.

a. How is a 16-bit memory address divided into tag, line number, and byte number? [1.5 marks]

b. Into what line would bytes with each of the following addresses be stored? [2 marks]

i. 0001 0001 0001 0001

ii. 1100 0011 0011 0100

iii. 1101 0000 0001 1101

iv. 1010 1010 1010 1010

c. Suppose the byte with address 0001 1010 0001 1010 is stored in the cache. What are the addresses of the other bytes stored along with it? [1.5 marks]

d. How many total bytes of memory can be stored in the cache? [1 mark]

e. Why is the tag also stored in the cache? [2 marks]
