This 2-bit adder was a lot of work to build. It uses a total of thirty-six 555 timers and it does have the option of adding or subtracting numbers. It’s a rather unorthodox use of the part, depending ...

As simple as the concept of adding two numbers appears at first glance, doing it in the 1970s in Intel’s 8087 FPU with its 69-bit adder was still a tall order. This is namely the core feature that ...

We worked our way up to logic gate implementations for half adders and full adders, as illustrated below. In closing, I asked you to start thinking about how we could use these functions to add two ...

In divide & conquer approach the 16 bit number is divided into individual 8 bits. If we continue to divide we reach the leaf level of the problem. In the leaf level of the D&C Tree is a 1 bit adder, ...

The paper presents a novel architecture of approximate adder and a novel generic error analysis method. The proposed architecture judiciously make use of time axis ...
