LS-DSP中串行分布式数字滤波器的功耗优化设计

A Low-Power Design of an SDA Digital Filter for LS-DSP

采用一种优化阶符的二进制数据表示方法,达到了减小LS-DSP内串行分布式计算滤波器的动态功耗的目的.实验结果表明,该方法可有效减小LS-DSP内串行分布式计算滤波器10%的动态功耗.

In order to reduce the power dissipation of a serial disbributed arithmetic（SDA） digital filter,a new data coding technique,called optimized radix-notation binary coding method, is put forward to express the sampled data. Experiment results show that the optimized radix notation binary coding method can reduce the power dissipation of SDA digital filter by about 10%.
