Abstract

By meas of Distributed Algorithm(DA), hardware design of FIR digital filter was discussed. Based on theory of data accu -mulation algorithm, FPGA hardware realization of parallel DA, series DA, and series -parallel DA were studied. By use of speed,resource and series-parallel DA,16-step constants coefficients high speed FIR filter was designed,and the filter was simulated under the eonditions of QuartusII5.0.Simulation results showed that the design method has valididity,real time effectiveness and fea- sibility.
