FPGA Design of FIR Digital Filter Based on Distributed Arithmetic
Zhipeng Jiang · Dianzi qijian · 2012
Distribute Arithmetic(DA)is an important method for realization of FIR based on FPGA.Requirement of Chip resources is very high and the running speed reduses with basic DA utilization and increase of data width.So parallel-DA is used to divide the original LUT into some small LUTs and send bit groups of all data to LUT simultaneously.Simulation results show FIR works well with reduction of hardware resourses consumption and operating speed is significantly improved.
