| 摘 要： | 提出了一种取代数字信号处理器的基于μnsp微控制器设计滑动平均滤波器的方法.该设计在进行信号滑动平均运算时仅需10n 6个时钟周期,极大地提高了执行速度,同时也能充分发挥微控制器的控制功能.通过实现5点滑动平均滤波器,证实了这种设计可以在比数字信号处理器系统成本更低的硬件环境中实现信号实时处理.这种设计不仅可以快速完成滤波算法而且能够简化系统设计,降低成本.

| Abstract: | A new design based on μnsp microcontroller unit(MCU) replacing the digital signal processor (DSP) to realize the moving-average filter was proposed. Using this method only costs 10n+6 clock periods in complex moving-average signal computation enhancing the execute speed highly and making full use of the control ability of MCU. The 5-point moving-average filter was realized which proved that this design could do realtime signal processing in low costs hardware environment compared to DSP system. This approach was capable of completing the filter algorithm rapidly, simplifying the system design and reducing the entire costs. |
