Abstract

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.

多态FIR滤波器与备份模式，使省电

提出了一种可在两种模式下工作的多态FIR滤波器。第一种模式被认为是标准模式，过滤器在其中执行正常操作。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(作为对由Vdd控制的多态门函数变化的响应)，滤波器的一些部分被断开。实验结果表明，在暂停一半水龙头的情况下，虽然功耗显著降低，但滤波器仍能达到合理的过滤质量。
