Design and Implementation of Algorithmic Based Fault Tolerant using Hamming Codes

ABSTRACT In modern electronic circuits pose a reliability threat, a many applications are necessary to use protection against soft errors, there is no exceptions in the field of communications and signal processing systems. In new trend interesting option is to use Algorithmic Based Fault Tolerant techniques (ABFT) that try to develop the algorithmic properties to detect and correct the errors. The ABFT technique is well suited for communications and signal processing applications. One example is Fast Fourier Transforms that are a input building block in many systems. Several protection schemes are proposed. Among this, probably the use of the Parseval or sum of squares check is most broadly known. In modern communication systems are impressively use several blocks that blocks are operated in parallel. This type of techniques are first applied to protect the FFTs. Subsequently two enhanced protection schemes that merge the use of error correction codes and Parseval checks are proposed. The proposed technique to reduce the implementation cost of protection.
