摘要
利用FPGA的并行数据处理及在线可重构的特性,提出了一种基于FPGA的高速且系数在线可配的FIR数字滤波器实现方案。采用该方案设计的滤波器,可使用户在不影响系统正常工作的情况下,实现对滤波器系数实时重新配置的目的。通过实践测试表明:该方案设计的FIR数字滤波器,在数字超声探伤系统中得到有效、灵活的应用。
The characteristics of parallel processing data and online reconfiguration of FPGA is used, an implement of dynamic coefficient and high-speed FIR digital filter is proposed. In this way, the user can real-time reconfigure the filter without affecting the system under the condition of normal work. Test shows this design of FIR digital filter can work effec- tively in the digital ultrasonic flaw detection system.
