How to Design a 16 Bit Full Adder in VHDL for Serial Addition
In this article, we will learn how to design a 16 bit full adder in VHDL for serial addition. A serial adder is a circuit that can perform binary addition of two numbers by processing one bit at a time. A full adder is a circuit that can add two bits and a carry bit and produce a sum bit and a carry out bit.
To design a 16 bit full adder in VHDL, we will use the following components:
A parallel input serial output (PISO) shift register that can convert a 16 bit parallel input into a serial output.
A D flip flop that can store one bit of data.
A full adder that can add two bits and a carry bit.
The schematic of the 16 bit full adder for serial addition is shown below:
