Suppose you want to add a new instruction to MARIE ISA, the instruction is swap between the data in memory at address x and that in the AC. Assume you have a temporary register connected to the bus at bus address = 5 a. (2 Points) Write the instruction format for this instruction, give it an appropriate opcode value, choose an address value you want. b. (4 Points) Write all the microoperations necessary to decode and execute this instruction, you must write the control signals needed for each microinstruction. c. (3 Points) Draw the timing diagram needed for the control unit to execute this instruction.
