An instruction in address (021)16 in the Simple machine has a mode bit I = 0, an operation code of the AND instruction, and an address part equal to (083)16. The memory word at address (083)16 contains the operand (B8F2)16 and the content of the AC is (A937)16. Go over the fetch and execute cycles and determine the content of the following registers at the end of the execute cycle: PC, MAR, MBR, AC, and OPR. Repeat the problem six more times starting with the operation code of another memory reference instruction with the initial values as defined earlier.
