A simple ALU is designed to perform 4 distinct operations: Addition, Subtraction, Logical AND, and Logical OR. Assuming a standard encoding scheme for operation selection, how many control lines are minimally required to select one of these four operations for the ALU?
Correct Answer:
To select one out of 'N' distinct operations, a minimum of 'log₂N' control lines are required. In this case, N = 4 (Addition, Subtraction, Logical AND, Logical OR). Number of control lines = log₂(4) = 2. Therefore, 2 control lines are minimally required to select one of the four operations.
