| 摘 要： | 根据FIR滤波器的特性和分布式(DA)算法的特点,基于FPGA实现FIR滤波器的原理和方法,在拆分查找表的基础上,利用串并结合DA算法对数字滤波器的设计进行优化,设计更高阶次的滤波器并节省所占用的硬件资源.采用串并结合DA算法设计了16阶FIR低通滤波器,在Quartus Ⅱ 7.0下进行仿真,结果验证了该方法滤波效果好,能够有效地减少FPGA硬件资源的使用,提高FIR的运算速度.

| Abstract: | According to the characteristics of FIR filter and distributed algorithm(DA),the theory and method of FIR Filter was realized using DA based on FPGA.On the basis of table partitioning,the designation of FIR filters was optimized by serial-parallel arithmetic aiming at filters with higher order while saving the hardware it would use.16-order FIR filters was designed by serial and parallel DA and simulated in Quartus Ⅱ 7.0.Results showed that the FIR filters were with small resource usage and high speed compared with traditional methods. |
