Question 1 (50 points): 4-way Set Assoc on the processor we have. We know it has 128KB L1 cache. It can also be kept in a 64-byte cache record side by side. a) Find how many sets there are. 128KB is just the space occupied by the adjacent data, excluding tags and other bits. b) If we have 36 bit addresses (meaning max 64 GB memory), how many bits are kept for Tag? c) If a very large integer array is read, each of which is 4 bytes, what is the maximum hit rate for this array? Note: Each line has 64 bytes next to each other, use this in the calculation
