Sample Program for CMSIS-DSP of Supporting NEON

What is this ?

This is a sample program of FIR filter for using CMSIS-DSP of supporting NEON.
This program is the sample program of the FIR filter based on SciPy FIR Filter, and it has replaced the mbed-dsp library to mbed-dsp-neon library.
Input signal and reference output are described in data.cpp.

The default setting of serial communication (baud rate etc.) in mbed is shown the following link.
Please refer to the link and change the settings of your PC terminal software.
The default value of baud rate in mbed is 9600, and this application uses baud rate 9600.

Supporting compiler is only ARMCC.


NEON対応CMSIS-DSPサンプルプログラム

概要

このプログラムは、SciPy FIR Filterに基づいたFIRフィルタのサンプルプログラムであり、mbed-dspライブラリをmbed-dsp-neonライブラリに置き換えています。
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。

mbedのシリアル通信(ボーレート等)のデフォルト設定は以下のリンクに示しています。
リンクを参考に、お使いのPCターミナルソフトの設定を変更して下さい。
mbedでのボーレートのデフォルト値は9600で、このサンプルではボーレート9600を使います。
