摘要

通过增加FFT构建块的基数，我们可以减少执行短期谱分析所需的算术运算的总数。对于一些等于或略小于12次方的分析点，使用基数12构建块可以减少功耗，通常在2到5之间。

A radix-12 FFT building block

By increasing the radix of an FFT building block, we can reduce the total number of arithmetic operations required to perform short-term spectral analyses. For a number of analysis points equal to or slightly less than a power of 12, use of the radix-12 building block reduces power consumption by a factor that lies typically between 2 and 5.<>
