| Abstract: | 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.... |
