摘要

针对快速傅里叶变换(FFT)网络，提出了一种新的基于算法的容错方案。结果表明，该方案在理论上实现了100%的故障覆盖率。通过将舍入误差考虑在内，提供了对FFT网络故障覆盖率的精确度量。结果表明，该方案在保持J.Y. Jou和J.A. Abraham方案的低硬件开销和高吞吐量的同时，显著提高了故障覆盖率。

A novel concurrent error detection scheme for FFT networks

A novel algorithm-based fault tolerance scheme is proposed for fast Fourier transform (FFT) networks. It is shown that the proposed scheme achieves 100% fault coverage theoretically. An accurate measure of the fault coverage for FFT networks is provided by taking the roundoff error into account. It is shown that the proposed scheme maintains the low hardware overhead and high throughput of J.Y. Jou and J.A. Abraham's scheme and, at the same time, increases the fault coverage significantly.<>
