| Abstract: | Communication and signal processing systems experience the soft error which make threat to modern electronics circuits. This makes protection against soft errors requirement for many communication and signal processing application. One of the basic building blocks used in many communication applications are FFT. To detect and correct the soft errors occurring in FFT blocks due to environmental changes, Error correction codes (ECC), parity sum of square (SOS), and parity - error correction codes (SOS-ECC) methods are adopted. Redundant module performs error correction using hamming codes. Parity SOS compares the magnitude of input square and output square and produce the result 0 as indication of no error. If there any error present, it produce the result as 1. Parity SOS-ECC combines the operation of ECC and parity SOS. This detect and correct the soft errors present in the parallel FFT’S blocks. The simulation were carried out using Xilinx ISE. The combined parity SOS-ECC produce the best results in terms of implementation complexity and recover the errors that are out of the tolerance range. The fault coverage for the parity SOS scheme and the parity SOS-ECC scheme is 99.9 % when the tolerance level for SOS checks. |
