Design a single bus gate level implementation of a machine that implements the following instruction set. You are to use a hardwired control unit. The project is worth a total of 50 total points. 40 of these points will be based upon the correctness of the design and the remaining 10 points will be determined by (documented) optimizations that you make to the design. In order to achieve credit, you must document your optimizations, describe the trade offs of each optimization, and justify your selected optimizations. Optimizations achieved by pipelining will not count, that is the objective of Project 4.
