hello ,
can you share c-code examples how to use neon ARMv8 intrinsics ?
mostly , I'm not sure , what results to expect.

Hello,
I am developing embedded software on Zynq MPSOC Cortex-A53 (Armv7/Armv8) for image processing, and I need some help for developing a specific algorithm.
The algorithm involves many calculations of FFT and matrix using. As highest priority, we…
Ne10 FFT 介绍
最近,我们更新了Ne10库里面的FFT算法。不管是ARMv7还是ARMv8平台,我们都利用NEON技术充分优化了FFT算法。现在Ne10库里的FFT算法,比大部分现有的FFT实现都要更快一些,比如FFTW,OpenMax DL。本文着重介绍Ne10库里的FFT的最新变化。
下面图表描述了Ne10的32位浮点复数FFT,FFTW和OpenMax DL FFT的性能测试结果。测试平台是ARM Cortex A9。X轴代表FFT的输入长度,Y轴代表了FFT算法运行时间…
