Hello
I am trying to understand how control signal, select source and destination. How they determine is it instruction or data, and how they do operation
I made handy diagram, I don't understand which control signal put the data to register R1 and R2.
Look at handy diagray
I am trying to make circuit, That should perform following function
Put immediate data to R1
Put immediate data to R2
Mov R1,R 2
MovR2,R 1
I understand if MOV R1,R2 than Enable R1 out, enable R2 and if MOV R2,R1 Enable R2 out, enable R1. I don't understand logic of signal when we put data to registers?
