Given the single-cycle datapath with control.which implements a
subset of MIPS instructions.Consider adding the following
instructions.
addp1m rd,rs,rt Interpretation: Reg[rd]= Mem[Reg[rs]] +
Reg[rt]
a.What should be added/modified in the datapath for this
instruction?
b.Which blocks are used to execute this instruction?For what
purpose?
c.What new signals should be added for this instruction? What
should be the values of new and existing control signals to execute
this instruction?
