A computer uses a set-associative cache with 8-blocks per set.   How many bits will be used for the counter to apply the (LRU algorithm)? Explain your answer.             The following blocks are referenced by the CPU and to be fetched from the RAM to the cache sequentially: (i   j    k    L   L    j  m  j   n    L    m     j    m     L    k    S     j    P    i    O     k) Assume that the cache set is empty and all the above blocks can be inserted into the set. Use the LRU algorithm to fill in the following table that describes the status of the cache locations for each called block.
