Whew. A lot has happened since my last update on our CPU project, and I have been really busy. Unfortunately, a lot of stuff is still in the pipeline, so I still cannot write about these, but I do have a new development. Bitwise Logic Operations In addition to arithmetic, the ALU also needs to perform basic logic operations. These are housed in the Comparator, inside the ALU. These include AND, OR, XOR, and NOT. They are implemented by running each corresponding bit of the tw
