چکیده :

Approximate arithmetic modules are attractive solution to save power consumption in error resilience applications. Full-adder (FA) as the core-computing module contributes major part of arithmetic modules in digital systems. However, designing the FA module to be applied in both approximate and exact modes would become a major goal in low-power integrated circuits design. In this paper, we present a new configurable FA with runtime configurability between exact and approximate modes at the transistor level. The configurability of the proposed FA achieves using embedded switches in the internal nodes of the circuit. Our circuit provides an output accuracy of 6 in approximate mode. We implemented our adder using GPDK 45-nm technology node and evaluated it by Cadence virtuoso. Our proposed adder consumes 23% lesser power compared to the Mirror Adder when operating in approximate mode.
