Application: This sample code uses the M4 DSP to calculate RMS and Standard Deviation.
BSP Version: M480 Series BSP CMSIS V3.04.000
Hardware: NuMaker-PFM-M487 Ver 3.0
This sample code uses the CMSIS DSP library to calculate statistics functions, including
Maximum
Minimum
Mean
Root mean square (RMS)
Standard deviation
Variance
User can use these functions to implement mathematical equations. The sample code compares the difference between using the DSP calculation time and calculates the efficiency improvement ratio.
