  • Author: Tholin
  • Description: Multiplies two 4-bit numbers presented on the input pins and outputs an 8-bit result.
  • GitHub repository
  • Clock: 6000 Hz

How it works

The multiplier is implemented using purely combinatorial logic. One 6-bit adder and two 8-bit adders as well as a heap of AND gates are the only used components.

How to test

Input any two numbers on the input ports, and check if the 8-bit result is correct.

External hardware

DIP switches for the inputs, and LEDs on the outputs, to be able to read the binary result.
