Any sort of help on these questions would be greatly appreciated.

Given a byte-addressable memory with 256 bytes, suppose a memory dump yields the results below. The address of each memory cell is determined by its row and column.

For instance, memory address 0x97 is the 9th row, 7th column, and contains the hexadecimal value 43. Memory location 0xA3 contains the hexadecimal value 58. The system from which this memory dump was produced has cache with 4 sets with 1 line per set where each block consists of 8 bytes. Assume the following sequence of memory address reads take place:

3D, BE, 44, 81, 3F, 47, 95, BA, B9, 57

a) When a reference is made to memory location 97, what is the block of bytes that are retrieved?

b) Assuming a direct mapped cache:

a. Show the format for a main memory address. Specify field names and sizes.

b. What does the cache look like after the 10 memory accesses have taken place?

c. What was the hit rate for this cache for the 10 memory accesses? ?

c) Assuming a set associative cache with 2 lines per set:

a. Show the format for a main memory address. Specify field names and sizes.

b. What does the cache look like after the 10 memory accesses have taken place?

c. What was the hit rate for this cache for the 10 memory accesses?

d) Assuming a fully associative cache:

a. Show the format for a main memory address. Specify field names and sizes.

b. Assuming all cache blocks are initially empty, blocks are loaded into the first available empty cache location, and cache uses a first-in-first-out replacement policy, what does cache look like after the 10 memory accesses have taken place?

c. What is the hit rate for this cache for the 10 memory accesses?
