Design a simple processor which does load, move, addition and subtraction operations. If one more operation is to be added, for example, $$swap$,$ what modifications to be done in the function register? $3.$ Draw the ASM and data path circuit for a bit counting circuit. $4.$ Design a multiplier which multiplies two n$-$bit unsigned numbers. $5.$ Draw the decoder circuit for function register of a simple processor which has four registers and performs four operations
