Suppose that immediately following the two read operations of question 2, the program does read operations on the following memory addresses (e.g., with lb or lw instructions): 520, 320, 668, 344, 520 (again), and 1020. Assuming the cache was empty prior to the read operations of question 2, state which of these read operations will result in cache hits, assuming a 2-way set-associative cache with a total capacity of 4 eight-word blocks and LRU replacement in each set.

Question 2: Suppose that a program does read operations on the following memory addresses (e.g., with lb or lw instructions): 332, 996. Give the number of the memory block that each of these addresses belongs to, for each of the following memory block sizes. (a) block size of one word (4 bytes) (b) block size of eight words (32 bytes)
