提出了一种可以在两种模式下工作的多态 FIR 滤波器。第一模式被认为是滤波器执行正常操作的标准模式。在第二种模式下，滤波器在降低的电源电压（Vdd）下工作，一些滤波器系数被重新配置（响应于由Vdd控制的多态门函数的变化）并且滤波器的一些部分被断开。实验结果表明，虽然当一半抽头暂停时功耗可以显着降低，但滤波器仍然能够实现合理的滤波质量。
A polymorphic FIR filter is proposed which can operate in two modes. The first mode is considered as a standard mode in which the filter performs a normal operation. In the second mode, the filter operates with reduced power supply voltage (Vdd), some filter coefficients are reconfigured (as response to the change of the polymorphic gates function which is controlled by Vdd) and some parts of the filter are disconnected. Experimental results indicate that while power consumption can significantly be reduced when half of the taps is suspended the filter is still able to achieve a reasonable quality of filtering.
