Modified reduced adder graph algorithm for multiplierless FIR filters
Fei Xu, Chip-Hong Chang, Ching Chuen Jong · Electronics Letters · 2005
A modified reduced adder graph (MRAG) algorithm and its hybrid version are proposed for efficient digital filter implementation. Several improvements are made to exploit fully the efficient optimal part of the n-dimensional reduced adder graph (RAG-n) algorithm. Simulation results demonstrate that MRAG is capable of generating lower adder cost solutions.
