[M480] M4 DSP Fast Math Function

[chhsieh3]

• Application: This sample code uses the M4 DSP to calculate sine and cosine.
• 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 Fast math functions, including

1. Sine (input value in radians)
2. Cosine (input value in radians)
3. Sine and Cosine (input value in degrees)

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.
