Implementation of FIR Filter Based on Distributed Algorithm
Qingming Huang · Dianzi qijian · 2011
To further reduce the scale of the ROM in implementing the DA(Distributed Algorithm),this paper firstly gave an introduction about how using DA(Distributed Algorism)to implement FIR digital filter and make a comprehentive synthesis of several methods directed to reduce ROM in implementing FIR filter.Meanwhile,we put forward a comprehensive method that combines the offset binary code with decomposing ROM to implement a digital FIR with 25 taps only using half of resource compared with the traditional method.The simulation result indicated that offset binary code was used to combine with decomposing ROM can reduce ROM resource at most in implementing FIR.
