Breadboard 8-Bit CPU

Divider Design

In prep for final design, I built a divider as a warmup for similar circuits.

Serial Loading 8-Bit Adder & Subtractor

This is the final design of a practice circuit to get familiar with the circuit design. The first green LED is the bit being loaded in to either register. The red LED shows which register is selected. The blue LED Indicates subtract mode. The yellow LEDs are the registers, the left is register A and the right is B. The output is the bottom green LEDs and is the result of A+B or A-B (mod 255) depending on the mode.
