How it works
The project takes one 8-bit input. The 8-bit input is split to form two 4-bit inputs. The inputs are put into an array that uses a combination of AND gates and Full Adders to get the individual values of the product. The Full Adders are coded using a combination of AND, XOR, and OR gates. The 4-bit array multiplier used for this project is shown in Figure 1.

How to test
Give an 8-bit input and check if the output is the correct product of the first and last 4-bits of the input.
