How Computers Subtract Without Subtracting: Two's Complement (The CPU You can Build, Ep. 4)
Can you build a computer CPU from scratch? YES! In this series, we are building a Logisim simulation of an 8-bit CPU using logic gates. If this series gets enough interest, then I will also plan on building a physical version of this CPU out of real transistors in the near future.
In this episode, we explain two's complement notation, which will allow us to easily modify our simple adder circuit from the last video to be able to handle binary subtraction.
