Step 2. Once you have traced the execution of instructions on the original Simple Computer and understand how the
instructions are decoded to control the datapath, modify the Simple Computer to include the new instructions shown in
Table 1. It may be possible to implement some of the required instructions by modifying only the instruction decoding
logic in the CPU datapath. The optional instruction might require additional changes to the CPU datapath as well as the
instruction decoder. See requirement 1 above for which files you are permitted to modify. . .J For each of the instructions, you will have to choose an opcode to represent it. You must not use one of the opcodes that
are in the original instruction set. A careful choice of the opcodes will reduce the changes that you must make to the design. Your report should include a table ofthe opcodes for each instruction that you implement. Your report should also
include a brief explanation of the changes made to the design to implement your instructionsI along with any problems
that you faced that you were unable to solve.» .J For each ofthe instructions that you implement you should include annotated simulation results in your report showing
the correct behavior of the instruction. Your report should also include a table {similar to Table 4! that contains the information necessary to understand the simulation results for each instruction. This table is similar to Table 3-11 in the
text and should explain the operation of each of your instructions. You are permitted to include additional information in the table if that is necessary to understand your implementation, particularly if you implement the optional instruction. .1 .1 aTable 4: Values from the simulation results for each new instruction implemented.» _ Assembl 0 code Other fields of .
