Design notes

• Clock cycles can be simulated by iterating over all CPU components and calling a cycle() function on each, which will execute whatever activities that component performs during a cycle. One complete iteration over all components corresponds to one clock cycle.

• Separate compiler will convert MIPS assembly instructions to hex instructions and the processor will take such a compiled file as input. The file will contain one hex instruction per line.
