Answer:
The ALU's function code should indicate the "or" function for beq/bne instructions. These instructions are used for branching in assembly language programming, where the control flow is diverted to a different section of the program based on a specific condition. The "or" function is used to check if either of the operands is non-zero, which helps in determining whether the branch should be taken or not. The ALU receives the function code as input and performs the corresponding operation on the operands, based on the instruction being executed.
