Single-cycle Implementation of MIPS processor

1.The basic single-cycle MIPS processor in the above figure only implements some instructions. We want to add a new instruction (andi $t1, $t2, imm-value) to an existing ISA.

a.Which existing components (if any) can be used for the new instruction?

b.Which new components (if any) do we need for this instruction?

c.What new signals do we need (if any) from the control unit to support this instruction?
