FPGA在数字滤波器设计中的应用

The Application of FPGA to Design of FIR Digital Filtes

介绍了 FIR数字滤波器的硬件实现技术 ,结合 Altera公司的 FLEX1 0 K系列芯片提出了实现 FIR数字滤波器的硬件电路的方案 ,设计出一种 8阶 FIR数字滤波器 ,并且推广到 1 6阶及 3 2阶 ,以及实现滤波器的 AHDL语言。基于FPGA的电路系统设计及其仿真结果表明此系统合理。

Hardware implemention technique of FIR filters is analyzed. Combining with the configuired Altera Corporation's FLEX10K series chip, the scheme of FIR filter hardware circuit is advanced and 8-tap FIR filter is designed, including AHDL to fulfill FIR filter and generalizing 16-tap and32-tap FIR filters. The circuit system design based on FPGA and its experimental results show that the system with FPGA is more reasonable and reliable and fulfill design requirement.
