this is a computer achritecture question. taught by the book computer organization and architecture designing for perfomance eighth edition. thank you

1. Design a direct mapping and 4 way set associative mapping structure with 128KB cache and 128 MB memory size. Write the address limits of main memory, line numbers of cache, set numbers and number of bits. Explain the structure and write the advantages, drawback of the method. (40 points) 2. Explain one 1 error correction process and solve the following problem. Assume that the 8-bit input word is written to memory as 01010011, with data bit D1 in the rightmost position. A soft erroz occurs and D4 changes its state. Find the syndrome word and explain the process correcting D4. (20 points) 3. Using the following reference string apply Optimai Page, Least Recently Used fand FIFO algorithms to the sequence for a memory with 4 frames. Write the number of page faults for each. (20 Points) 1,4, 8, 5, 2, 7,0,4,3,4,1, 8, 2, 5, 6, 9, 5, 4, 0, 7, 3, 4, 8, 1 4. Explain RAID and types of RAID (20 Points)
