coding neon
This is the first part of a series of posts on how to write SIMD code for NEON using assembly language. The series will cover getting started with NEON, using it efficiently, and later, hints and tips for more experienced coders. ,When writing code for NEON, you may find that sometimes, the data in your registers are not quite in the correct format for your algorithm. We explore this in further detail here. ,,In this post, we will look at how to efficiently multiply four-by-four matrices together, an operation frequently used in the world of 3D graphics. ,Chinese Version 中文版：NEON编码 - 第4部分: 左右移位This article introduces the shifting operations provided by NEON, and shows how they can be used to convert image data between commonly used color depths. Previous articles in this series:Part 1: Loads and Store... ,In the first post on NEON about loads and stores we looked at transferring data between the NEON processing unit and memory. In this post, we deal with an often encountered problem: input data that is not a multiple of the length of the vectors you want t, EDIT: From your update, you may misunderstand what the NEON processor does. It is an SIMD (Single Instruction, Multiple Data) vector processor. That means that it is very good at performing an instruction (say "multiply by 4") to several pieces,Arm NEON technology is a SIMD (single instruction multiple data) architecture extension for the Arm Cortex-A series processors. It can accelerate multimedia and signal processing ... and finally, NEON assembly code. Detailed information on NEON programmin, 主流支持目标平台为ARM CPU的编译器基本都支持NEON指令。可以通过在代码中嵌入NEON汇编来使用NEON，但是更加常见的方式是通过类似C函数的NEON Instrinsic来编写NEON代码。就如同NEON hello world一样。NEON Instrinsic是编译器支持的一种buildin类型和函数的集合，基本涵盖NEON的所有指令， ...,Motivation. ○ SIMD critical for video performance. – It's cheap for CPUs to add wider ALUs. – It's cheap parallelism (no locking/synchronization). ○ Even if you won't write the asm, we need to design code that can be vectorized. – Need to unde
