Repeat 4.34.3 for your extended datapath from 4.34.4.

Exercise 4.34.3

What needs to be done to support undeined instruction exceptions in your datapath from 4.34.1? Note that the undeined instruction exception should be triggered whenever the processor encounters any other kind of instruction. The remaining two problems in this exercise also refer to this MIPS instruction:

Exercise 4.34.4

Describe how to extend your datapath from 4.34.1 so it can also support this instruction. Your extended datapath should be designed to only support instances of these two instructions.

Exercise 4.34.1

Describe a pipelined datapath needed to support only this  instruction. Your datapath should be designed with the assumption that the only  instructions that will ever be executed are instances of this instruction.
