QUESTION $5$

When instruction or $$9,$$$10,$$$9$ is executed on a multi$-$cycle MIPS CPU, select all the correct answers from below:

At the $2$ nd cycle, the content of $$10$ is written into register B $.$

At the $2$ nd cycle, ALU is performing or operation.

If the content of register B is flipped by a fault during cycle $4,$ this would not affect the correctness of this instruction.

If we observe Branch$=1$ in hardware during some cycle of this instruction's execution, then something must be wrong.

At the $4$th cycle, WD$3$ of RF will receive the data from ALUOut register.
