Forwarding Logic Design

question 13

Essay

Forwarding logic design. For this problem you are to design a forwarding unit for a 5- stage pipeline processor. The forwarding unit returns the value to be forwarded to the current instruction. There are three places that the values for register RS and register RT can come from: decode stage (register file), memory stage, and write-back stage. The write-back and memory stage information consists of: _INDEX- explaining which inflight register index is to be written _VALUE- the value that is to be written _ENABLE- whether or not the instruction in the stage is writing.
The decode stage simply states the register index (for RS and RT) and the corresponding register value from the register file.
Generally three values could exist, one of which the forwarding unit should choose for each of the RS and RT register value requests. The memory stage has value MEM, the write-back stage has value WB, and the register file has value RS-REG or RT-REG.
Using the table below which contains information about all of the instruction stages, indicate which value should be forwarded to the current instruction: MEM, WB, RS-REG, or RT-REG. Each line represents a Forwarding unit evaluation; there is no connection between evaluation lines in the table. You do not need to worry about hazard detection, only value bypassing.

Explain the concepts of selection bias, nonresponse error, and nonsampling error.

Understand the importance and challenges of obtaining a representative sample.

Discuss the impacts of sampling and nonsampling errors on research findings.

Illustrate the process and criteria for choosing an appropriate sampling method for specific research needs.
