Hi, I need to design a state machine for a simple CPU. The cpu has a word size of 4 bits, 4 registers, and 2 register ports (A and B) which go to a ‘181 ALU. Our data-input device consists of two DIP switches, which go to the data-in port of the register file. The sole memory employed in this device is featured within the register file. The register file will be comprised of simple ‘273 chips. The selected instructions are addition, transitivity, and subtraction.

Thanks.
