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.
