NEON介绍在移动平台上进行一些复杂算法的开发，一般需要用到指令集来进行加速。NEON 技术是 ARM Cortex™-A 系列处理器的 128 位 SIMD（单指令，多数据）架构扩展，专门针对大规模并行运算设计的，旨在为消费性多媒体应用程序提供灵活、强大的加速功能，从而显著改善用户体验。

On 32-bit ARM NEON, the following: -mfpu=neon -mfloat-abi=softfp|hard, depending if you are on a softfp/hardfp system. Most current distributions are using a hard floating-point ABI, so go for the latter, or just leave the default and just pass -mfpu=neon. On 64-bit ARM, SIMD is enabled by default, you don't have to do anything extra.

NEON Types in C: The last method is to write your own code that uses special NEON C types. To do this you need to include the NEON header file. See Below.

Each of the Q0-Q15 registers maps to a pair of D registers, as shown in the following figure. A software library for best-in-class machine learning performance on Arm The Arm Compute Library is a collection of low-level machine learning functions optimized for Cortex-A CPU and Mali GPU architectures. The library provides ML acceleration on Cortex-A CPU through Neon, or SVE and acceleration on Mali GPU through Open CL. Arm Neon is an advanced single instruction multiple data (SIMD) architecture extension for the Arm Cortex-A and Arm Cortex-R series of processors with capabilities that vastly improve use cases on mobile devices, such as multimedia encoding/decoding, user interface, 2D/3D graphics and gaming. compiler llvm openmp simd avx2 vectorization avx512 compiler-optimization arm-neon loop-optimization spmd outer-loops function-vectorizer Updated Nov 25, 2020 C++ The Advanced SIMD extension (aka NEON or “MPE” Media Processing Engine) is a combined 64- and 128-bit single instruction multiple data (SIMD) instruction set that provides standardized acceleration for media and signal processing applications for ARM Cortex A (ARMv7) processors and the goal of these instructions is similar to MMX, SSE and 3DNow! extensions for x86 processors. Some application developers may be not familiar with NEON assembly coding so Ne10 library was created to let developers get the most out of ARMv7/NEON without arduous assembly coding.

If this is not specified, no mfloat-abi specification is passed, and the compiler default is used.

SSE on ARM can be complicated, but there are a couple of libraries We could depend on,  There are several libraries and tools leveraging SIMD processors with different techniques. Ne10, 3-clause BSD, Math functions optimized for ARM, NEON. C/C++ programmers hence implementing SIMD enhances software library. However, the barriers to entry Programming for ARM NEON has been made  The best option for you seems like it would be to simply link the other libraries in your assembly project.

If you are developing for an ARM Cortex-A9 then NEON C Intrinsics should be good enough, but for Ne10 is a library of common, useful functions that have been heavily optimised for Arm-based CPUs equipped with NEON SIMD capabilities. It provides consistent, well-tested behaviour, allowing for painless integration into a wide variety of applications via static or dynamic linking.

If you just NEON optimize part of your loop instead of the entire loop, you get major penalties and so the NEON code is perhaps just 30% faster or perhaps even slower than regular C code. But a full NEON loop can often give you 300% - 2000% speedup! If you are developing for an ARM Cortex-A9 then NEON C Intrinsics should be good enough, but for
