The instructions

ADD R₁, A, B
ADD R₂, C, D
MUL X, R₁, R₂

evaluate the expression $X = (A + B)(C + D)$ in which of the following?


Solution

A 3-address instruction has the form:


Result = Operand1 op Operand2


Example:


ADD R₁, A, B → R₁ = A + B

ADD R₂, C, D → R₂ = C + D

MUL X, R₁, R₂ → X = R₁ × R₂


Each instruction uses three addresses (two operands and one result).
