Introduction to Computer Architecture Adding New Instructions The basic single-cycle MIPS

Introduction to Computer Architecture Adding New Instructions The basic single-cycle MIPS implementation can only implement a few instructions. New instructions can be added to an existing ISA, often by reusing existing hardware. For the following instructions, answer the following questions to explain how to add them to the single-cycle architecture. You may wish to draw your modifications on the ISA diagram as well. Which existing blocks (if any) can be used for this instruction? How will the existing blocks be used to support this instruction? What new or modified hardware (if any) do we need for this instruction? What new signals (if any) do we need from the control unit to support this instruction
