How it works
This project uses a 4x4 Array Multiplier to multiplies two four-bit numbers together, using a series of full adders to result in an 8 bit product (figure 1). The multiplier works by systematically multiplying each bit of the first number with each bit of the second number. These partial products are then combined using a series of full adders to form the final result.

How to test
Input two 4-bit binary numbers and manually verify the output. For example: 1st num: 1001 2nd num: 1011 Output: 1100011 (binary), or 0x63 (hexadecimal) The format of the output can be adjusted in test.py, but the value they represent should be accurate to the product of the two 4-bit binary numbers.
