The Implementation of Digital Filter based on Stochastic Computation
Jianhao Hu · China Integrated Circuit · 2010
A lowpower digital filter based on stochastic computation is proposed,in which the traditional digital filter algorithm is improved to be mapped to the probability field.The serial and part parallel structures are proposed based on the probability digital filter algorithm.The signal to noise ratio(SNR) is also analyzed.The filter based on stochastic computation has simple hardware structure,and more error tolerant.The proposed stochastic filter can be applied in the lowSNR and lowhardware cost field.
