The Design of FIR Filter Base on Improved DA Algorithm and its FPGA Implementation ABSTRACT: When the DA (distributed arithmetic) algorithm is directly applied in FPGA (field programmable gate array) to realize FIR (finite impulse response) filter, it is difficult to achieve the best configuration in the coefficient of FIRfilter, the storage resource and the computing speed. According to this problem, the paper provides the detailed analysis and discussion in the algorithm, the memory size and the look-up table speed. Also, the corresponding optimization and improvement measures are discussed and the concrete hardware realization of the circuit is presented. The design based on Altera EP2C5T144C8 chips is synthesized under the integrated environment ofQUARTUSII7.1. The results of simulation and test show that this method greatly reduces the FPGA hardware resource and the high speed filtering is achieved. The design has a big breakthrough compared to the traditional FPGA realization. Did you like this research project? To get this research project Guidelines, Training and Code...
