A video frequency bit-parallel CMOS FIR median hybrid filter

Abstract

Abs t r ac t Fast pipelined implementat ion of t h e F E Median Hybr id filter has been designed on CM09. The Blter structure combines linear averaging subBltto a median opera t ion in a way that leads to a very efeeieet implementation. The fi l ter removes noise while preserving sharp edges in t h e signals. The integrated circuit c a n operate up to SOME. clock r a t e s and it is capable of 5ltving real time video aignals including future HDTV applications. The window size is adjustable from S to 257 samples.
