endmoduleTask $4-5$: Add the AND, ZERO, SUB, and STORE ACC Instructions

In this task you get to demonstrate your understanding of your microprocessor by adding

instructions to your instruction set. Add the AND, ZERO, SUB, and STORE ACC instructions to

your microprocessor circuit.

$$ The AND instruction should perform a bitwise AND operation of the value in the

accumulator with an operand from the RAM and store the result in the accumulator.

$$ The ZERO instruction should store the hex digit $0$ in the accumulator by subtracting the

accumulator from itself and storing the result back in the accumulator.

Version $1\mathrm{.}1$ Fall $202422$

$$ The SUB instruction gets the next value in the RAM and subtracts it from the

accumulator by forming its two's complement, adding the result to the value already in

the accumulator, and then storing this result back into the accumulator.

$$ The STORE ACC instruction should write the contents of the ACC into a location in RAM

specified by the instruction$$s operand
