verilog or vhdl code for low power error tolerant adder

Abstract: Problem statement: In modern VLSI technology, the occurrence of all kinds of errors has become inevitable. By adopting an emerging concept in VLSI design and test, Error Tolerance (ET), a novel Error-Tolerant Adder (ETA) is proposed. The ETA is able to ease the strict restriction on accuracy and at the same time achieve tremendous improvements in both the power consumption and speed performance. When compared to its conventional counterparts, the proposed ETA is able to attain improvement in the Power-Delay Product (PDP). Conclusion/Recommendations: One important potential application of the proposed ETA is in digital signal processing systems that can tolerate certain amount of errors. Delay and power are compared for various adders like RCA and CLA. It is found that ETA has high speed and less power compared to its counterparts.
