Most approaches to the ramiication problem are based on the principle of minimization of change. It turns out, however, that this principle can not be applied uniformly, and many modern approaches use a clas-siication of the uents whereby change is only minimized in some of the uents. The present article reviews these approaches and their underlying motivations. It also presents a uniied formal...

Various implementations are known for the efficient implementation of adders. As opposed to traditional optimization techniques a statistical approach using early termination detection is used in this article to obtain efficient implementations for large operands. The completion detection logic is described and the efficiency of the approach is shown and analyzed analytically and through comput...

Adders are some of the most critical data path circuits requiring considerable design effort in order to squeeze out as much performance gain as possible. Various adder structures can be used to execute addition such as serial and parallel structures and most of researches have done research on the design of high-speed, low-area, or lowpower adders. Adders like ripple carry adder, carry select ...

The FFT is commonly used essential tool in digital signal processing applications .The adders used in Conventional Fast Fourier transform(FFT) are no longer appropriate for the reason that of its degraded rapidity concert. There are many dissimilar kinds of fast adders such as Carry Select Adder, Carry Save Adder and Carry Look Ahead Adder have been used for Fast Fourier Transform. However, the...
