Single-Cycle Processor Datapath (MIPS ASSEMBLY)

In this problem, you will modify the single-cycle datapath we built up to support the JAL instruction. The datapath that we will start with has been produced on the next page. Your job is to implement the necessary data and control signals to support the JAL instruction, which we define to have the following semantics.

JAL : R31 PC + 4

PC PC3128 || Immediate || 0^2

Add to the datapath on the next page the necessary data and control signals to implement the JAL instruction. Draw and label all components and wires very clearly (give control signals meaningful names; if selecting a subset of bits from many, specify exactly which bits are selected; and so on)
