Question

Give an illustration of how the MUL and one-operand IMUL instructions prevent overflow from occurring.

Expert Solution
Step 1

One, two, or three operands can be input into IMUL. It enables operations on bytes, words, and words. Only signed numbers can be used with IMUL.

When the low half of the output, which is read as a signed integer of the appropriate size, does not equal the outcome of multiplying the two input values mathematically, IMUL sets the overflow flag.
