Computer Organization, Extra Credit 4

Due Friday, 12/5 (late 6am 12/6)

Assume there is another condition code V that tests for signed overflow. It will be set after each ALU operation.

If the operation is not F0=F1=1, then the V bit is cleared.
If the operation is F0=F1=1, then the V will be set if there is signed overflow.

Write the Mic-2 instructions that will implement IFICMP_GTS offset. It will pop the top two values from the stack and jump if the second value is greater than the first value when treated as signed numbers. If the V is set, it means that the current value of the N bit is wrong.
