Incrementing the program counter is done during instruction fetch so as to point to the next instruction address. This operation becomes dummy (unnecessary) in case the instruction fetched is a JUMP...

the next instruction address. This operation becomes dummy (unnecessary) in case

the instruction fetched is a JUMP (branch) instruction. To eliminate this, we can

suggest another approach. Instead of incrementing the program counter during the

fetch-phase (subcycle), it can be done during the execution-phase along with the last

microoperation, if only applicable. No computer seems to follow this approach. Identify

the flaws in our suggestions. (Hint: interrupts, cycle time )
