Repeat 4.34.2 for your extended datapath from 4.34.4.

Exercise 4.34.2

Describe the requirements of forwarding and hazard detection units for your datapath from 4.34.1.

What needs to be done to support undefined instruction exceptions in your datapath from 4.34.1? Note that the undefined instruction exception should be triggered whenever the processor encounters any other kind of instruction.

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.

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.

Exercise 4.34.4

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.
