# I have posted this question several times, but one of your experts solved the wrong number with an irrelevant answer. It's too much pathetic for me. Did I purchase it for it? You can take 8-10hrs to solve this problem, and if you don't have enough knowledge to solve this answer, please skip it.

Hi Experts! Would you please try to solve this as soon as possible with 100 % Accuracy? If possible, please do it.

You have to follow some instructions which I mentioned below. If you don't follow my instructions, please skip my questions.

You have to answer only #2.. I repeated, don't do other numbers.

Instructions are given,

• You need to show detailed calculations, as required.
• You need to provide clear diagrams, as required. All diagrams should be clearly drawn

2. 13 20 (5x4) A computer system contains a main memory of 32KB. It also has a 256Bytes cache divided into two-lines/set with 4Bytes per line. Assume that the cache is initially empty. The processor fetches words from locations in order: 1032, 1033, 136, 137, 138, 904, 905, 264, 265, 138, 1034, 906 in that order. Assume an LRU is used as replacement algorithm. Calculate the Hit ratio. Show the state of cache at the end. How many blocks are replaced? Estimate the improvement resulting from the use of the cache, if the cache is 10 times faster than RAM. Just comment relative Hit Ratio and execution time if 4-way set associative cache is used instead
