Assume a fully associative cache with 4 lines. Assume that the initial state of the tags are Joe, Kim, Sue, and Meg respectively as shown below. Applying the LRU policy, complete the table below for the following tag address sequence: Joe -> Dan -> Sue You can complete the table by replacing labels noted from A through P. Note that the TAG will be the names and COUNT will be numbers. The first column "Joe" is completed for you as a reference. INITIAL TAG Joe Kim Sue Meg A= COUNT 0 1 2 3 Joe TAG Joe Kim Sue Meg B= COUNT 3 0 1 2 Dan TAG A с E G |= COUNT B D F H Sue TAG I K M O J= COUNT J L N P
