Consider two 8-bit registers A holding OX5D and B holding O×AF. Both patterns are treated as signed numbers. If the CPU performs A - B, would there be overflow, underflow, or neither? Justify. (See lecture slides for examples) Step 1: Compute A - B Step 2: The resulting pattern represents a number. Step 3: A O and B 0. The expected result of A - B is Step 4: has happened.
