Application: The CMSIS-DSP library is a suite of common signal processing and mathematical functions that have been optimized for the NuMicro® M4 microcontroller. This document describes how to use the basic math functions from the Keil M4 DSP library to help users get DSP high performance advantages.
BSP Version: M480 Series BSP CMSIS v3.03.000
Hardware: NuMaker-ETM-M487 v1.1
Users use all the functions of the Keil M4 DSP library to implement basic math functions, such as vector dot product, vector multiply, vector addition.
There are two methods to implement vector operations in the example. One is using Keil M4 DSP library perform vector operations and the others is using C functions. Compare with C functions, DSP library has the faster execution speed.
