The source can be register or memory location. When a signed byte (8-bit) is multiplied by AL a signed result will be put in AX. (AL) × (8-bit operand) → (AX)

Witryna20 wrz 2024 · The imul instruction has two basic formats: two-operand (first two syntax listings above) and three-operand (last two syntax listings above). The two-operand form multiplies its two operands together and stores the result in the first operand. The result (i.e. first) operand must be a register.
