[24 pts] 2- For the pseudo-CPU shown below (adapted from Figure 3.9 in the textbook), explain whether or not each of the following microoperations can be performed in a single clock cycle. Assume AC and MDR each contain 16 bits, PC and MAR each contain 12 bits, and IR is 4 bits. You may assume that the AC register is wired as shown in the diagram below. (a) MAR AC, MDR + MAR (b) IR - MDR, MAR MDR (c) MAR - MDR, MDR + M(MAR) (d) MDR + AC + 1 (e) AC + MDR, PC+ PC + 1 (f) PC + PC + 2 ALU AC ALU Internal Data Bus Result Select MDR IR PC MAR MUX Internal AC To/from memory and I/O devices CU control signals Enable Extemal control signals Internal Data Bus [24 pts] 2- For the pseudo-CPU shown below (adapted from Figure 3.9 in the textbook), explain whether or not each of the following microoperations can be performed in a single clock cycle.
