Question: Consider an instruction register that has 4 bit for instruction, 12 bits for Address1 and 12 bits for Address2. 1) What is the maximum number

Consider an instruction register that has 4 bit for instruction, 12 bits for Address1 and 12 bits for Address2. 1) What is the maximum number of distinct operation codes for this processor? 2) What is the maximum memory size on this machine? 3) How many bytes are required for each operation?

I solved the above. I'm stuck on the below. I think I'm overthinking it...or misunderstanding something.

*****If the size of the op code field in Exercise above were increased from 4 to 8 bits, what would now be the theoretical maximum size of the instruction set?
