摘要：
In frequency-domain adaptive filtering (FDAF), the "crossover point" where the frequency domain becomes more efficient than the time domain is asymptotically 1.5 times as high for a DSP software realization as for a VLSI hardware realization. However, actual software realizations of FDAF may require as much as twice the computation predicted by theory, depending on the processor chosen.
