Abstract


As in performance, cost, power consumption and other advantages , FPGA-based signal processing module has been widely used in various signal processing fields. FPGA especially suitable for multiply and accumulate (MAC) and other repetitive DSP tasks . This article describes the application of FPGA in the superiority of digital filter design . Inherent flexibility of the FPGA also allows designers to keeping pace with new changes in standards and can provide a viable way to meet the ever- changing standards requirements. This paper mainly discusses FPGA-based digital signal processing implementation. First elaborated the theoretical basis of digital signal processing , focusing on the principle of the FIR digital signal filtering . This article discusses the FIR digital filter structure and algorithm analysis, discussed and compared in several different algorithms on FPGA . In modern digital signal processing , the sampling rate is getting higher and higher after the data , which is digital signal processing also put forward higher requirements. To meet this requirement , one way is to increase the rate of the digital signal processing ; Another method is to slow down the sampled data is processed . Multirate signal processing techniques to slow down the implementation process provides a theoretical basis . This paper discusses the multi-rate signal processing fundamentals , presents a heterogeneous structure improvements , but also on the FPGA multi- rate signal processing applications to do a certain depth theoretical study . Finally, based on the foregoing discussion , the paper focuses on the distributed algorithm in FIR filter application . In order to verify distributed algorithms in FPGA advantages of digital signal processing , paper -based Quartus II9.1 platform , focusing on design and implement a distributed architecture based on parallel FIR filter , and verified .
