1. Consider a machine with a direct mapped cache that has 8-sets and has a block size of 4-bytes. Memory addresses are 13-bits and each memory access from a processor requests a byte from the cache. The contents of the cache are as follows, with all numbers in hexadecimal, Cache Line Set IndexTag Valid Byte 0Byte Byte 2 Byte 3 30 78 0 09 38 1 6E 0 06 0 C71 71 91 46 0 72 92 3F D4 IF DA C5 D3 9A OB 12 5C B3 59 (a) (2 points) Calculate the size of the cache in bytes. (b) (3 points) Indicate the number of bits used to determine o the block offset e set index: * tag
