mbed OS 5 version of sample program indicating the usage of CMSIS-DSP which supports NEON

Overview

This sample program shows the example for usage of CMSIS-DSP supporting NEON.
Concretely, in this program, mbed-dsp-neon is used instead of mbed-dsp and FIR filter based on SciPy FIR Filter is carried out.
Input signal and referenced output are implemented in data.cpp.

With respect to the default configuration of serial communication (e.g. baud rate), please refer to the link below: https://developer.mbed.org/teams/Renesas/wiki/GR-PEACH-Getting-Started#install-the-usb-serial-communication

Note that only ARM Compiler 5 is available at present for building this program.

mbed OS 5版NEON対応CMSIS-DSPサンプルプログラム

概要

本プログラムはNEON対応CMSIS-DSPの使用例を示すサンプルプログラムです。
具体的には、mbed-dspライブラリの代わりにmbed-dsp-neonを用いてSciPy FIR Filterで示すFIRフィルタ処理を行います。
data.cppには入力信号データと基準出力データが記載されています。

デフォルトのシリアル通信（ボーレート等）設定に関しては以下のリンクを参照してください。
https://developer.mbed.org/teams/Renesas/wiki/GR-PEACH-Getting-Started#install-the-usb-serial-communication

なお、現時点で本プログラムをビルド可能なコンパイルはARMコンパイラ 5 のみですのでご注意ください。
