摘　　要：针对数字信号处理实时性高的需求,提出了一种新型高速FIR滤波器实现方法。该方法采用了多速率信号处理技术、分布式算法和流水线技术,使多速率DAFIR滤波器计算量大大减少,处理速度得到极大提高。在QuartusⅡ平台上对DAFIR滤波器进行了仿真,仿真结果进一步验证了该方法的有效性。A new method for implementing multi-rate DA FIR filter is presented to meet high speed real-time signal processing. After multi- rate signal processing,distributed arithmetic and pipeline technologies are applied in multi-rate DA FIR, the quantity of computing is decreased heavily,and the speed of processing is increased. A simulation on Quartus Ⅱ indicates that multi-rate DA FIR can meet the need of real-time.
