| الملخص: | <p dir="ltr">Effective self-repairing can be achieved if the fault along with its exact location can be determined. In this paper, a self-repairing hybrid adder is proposed with fault localization. It uses the advantages of ripple carry adder and carry-select adder to reduce the delay and area overhead. The proposed adder reduces the transistor count by 115% to 76.76% as compared to the existing self-checking carry-select adders. Moreover, the proposed design can detect and localize multiple faults. The fault-recovery is achieved by using the hot-standby approach in which the faulty module is replaced by a functioning module at run-time. In case of 3 consecutive faults, the probability of fault recovery has been found to be 96.1% for a 64-bit adder with 8 blocks, where each block has 9 full adders.</p><h2>Other Information</h2><p dir="ltr">Published in: IEEE Access<br>License: <a href="https://creativecommons.org/licenses/by/4.0/legalcode" target="_blank">https://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1109/access.2020.3016427" target="_blank">https://dx.doi.org/10.1109/access.2020.3016427</a></p> |
