Error Characteristics of Approximate Adders

APPROXIMATE ADDERS:

--->Approximate adders have been considered as a potential alternative for error-tolerant applications to trade off some accuracy for gains in other circuit-based metrics, such as power, area and delay.

--->Earlier approximate adder designs have shown substantial advantages in improving many of these operational features.

--->Error features such as the error rate and the mean error distance are obtained using this framework without developing functional models of the approximate adders.

--->Approximate computing is a technique to reduce the power,area and delay.

--->Approximate adders are used to reduce the number of Transistors.

--->Approximate adders used in IMAGE PROCESSING APPLICATION.
