From these charts, we can conclude that float complex FFT shows the similar or better performance boost between the AArch64 mode and the AArch32 mode. But for int32/16 complex FFT, the performance boost in the AArch32 mode is usually better than in the AArch64 mode (but this doesn’t...
比如音视频应用中,对于视频处理,多采用OpenGL ES来利用显卡的并行计算能力来提高图像和视频的速度,而在音频方面则可以充分利用SIMD来提升信号处理(例如FFT/IFFT)的速度,从而增强用户体验。 目前市场上的Android和iOS设备多采用ARM架构的芯片,而在ARM Cortex-A和Cortex-R系列处理器的IP设计中引入了Arm Neon技术,Arm Ne...

计算结果跟用 python 里 fft 小数点后 5-6 位差不多，其他的还没仔细测试，感觉还挺强悍的。

We also have a handful of carefully prepared sample code snippets in thesamples/directory that outline how Ne10 can be used to accomplish a number of common tasks. These include example programs to perform theFFT,FIR, andmatrix multiplyoperations. ...

If you want to make an FFT less than 256 points, maybe you can run the program perfectly, depends on the platform you are implementing. But if you have a problem, you may not have enought "heap" memory. To avoid this problem it is necessart to change the properties of the linker scr...
