An efficient algorithm-based concurrent error detection for FFT networks

摘要

In this brief contribution a new algorithm-based concurrent error detection scheme employing the checksum approach is proposed for FFT networks. Our design allows high error coverage with low false alarm rate by applying the linear weight factors to the checksums. Due to the simplicity, the hardware overhead is relatively small and errors can be quickly detected. The design is also shown to be easily expanded for multidimensional FFT networks.
