[M480] M4 DSP Statistics Functions

[chhsieh3]

• 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.
