Part A: Single Cvcle Processor

Figure A: Single Cycle Processor Datapath

Run the given Lab$2.$asm file on MARS simulator. Using the Tools$->$MIPS X Ray, you would be able to see the datapaths of the instructions. Based on the above figure, what will be the values of the followings when the following instructions are executed:

Hint:

Identify the instruction during the specified cycle.

Identify the datapath of the identified instruction, then determine the values of the labels for that datapath.

The datapath follows the instruction class datapath, i$.$e$.,\frac{R}{\text{I}}\frac{?}{?}\frac{J}{l}oa\frac{d}{?}$ store.

If the datapath does not cross through the label, mark it as $\text{'}x\text{'}.$
