Question

While executing the add instruction the ALUOp controll signal is:

a)None of the other answers
b)00
c)10

Answer 1

The ALUOp control signal is a binary encoding used to determine the operation to be performed by the Arithmetic Logic Unit (ALU) in a computer system. The correct answer is None of the other answers.

Step-by-step explanation:

The ALUOp control signal is a binary encoding used to determine the operation to be performed by the Arithmetic Logic Unit (ALU) in a computer system. In this case, the choices given are a) None of the other answers, b) 00, or c) 10. To determine which signal corresponds to the add instruction, we can analyze the binary encoding.

Let's consider the three options:

1. a) None of the other answers: This option suggests that there is another valid signal for the add instruction, but it is not provided in the given choices.
2. b) 00: In many computer systems, the ALUOp control signal is a 2-bit binary encoding. In this case, 00 could be assigned to the add instruction.
3. c) 10: Similarly, 10 could be assigned to the add instruction in some computer systems.

Since both b) 00 and c) 10 could be valid encodings for the add instruction, the correct answer to this question is None of the other answers.
