FPGA is used to acquire the data parallelly for comparing the data of the same column in the median filtering window. Comparing results shared by adjacent filter window are saved temporarily to match the new round of median filtering by using FPGA internal resources. This method can reduce the comparing times from current 21 down to 13  and improve the algorithm efficiency nearly 40%.The experimental results prove that the optimized algorithm can filter a 1K1K gray-level image in about 20ms  which ensure the proposed algorithm can be applied in the real-time image median filtering system. 2010 IEEE.   A multi-channel, area-efficient, audio sampling rate interpolator (EI CONFERENCE) 会议论文  OAI收割 2009 8th IEEE International Conference on ASIC, ASICON 2009, October 20, 2009 - October 23, 2009, Changsha, China 作者:  Wang D. 收藏  |  浏览/下载：39/0  |  提交时间：2013/03/25 The area and power consumption of sampled rate converter are governed largely by associated digital interpolationfilters. This paper presents a novel multi-channel  area-efficient audio sampling rate interpolator  whose conversion ratio is 1:2 and 1:4. Several architectural and implementation features reduces the complexity of the filter and allow its realization in a die area of 0.032mm2 in 0.18 m technology  meanwhile timing multiplexer scheme reduces clock frequency to minimum. Experiments show proposed methods could not only saved hardware resources but also reduce power consumption  so it is very suitable for consumer electronics. 2009 IEEE.
