uint16x4_t vadd_u16 (uint16x4_t, uint16x4_t) Form of expected instruction(s): vadd.i16 d0, d0, d0 Dont forget to include the arm_neon.h file.~ Example instruction: VADD.I8 D0, D1, D2 this is doing a neon add and the type of numbers your adding is 8bit Ints D1:[ 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 ] + D2:[ 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 ] = D0:[ 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 ] */ NEON arithmetic instructions typically distinguish between these data types in order to apply the same operation to all lanes. For example, vadd.f32 considers a 64-bit register as 2x 32-bit floats, whereas vadd.i8 considers it as 8x 8-bit signed integers. For a more substantive description, please see the official ARM documentation. NEON is an advanced SIMD unit from ARM that resides on almost all modern smart phones ( iPhone 3GS, Galaxy S, Nexus One or later) NEON is capable of computing demanding operations such like colorspace conversions, image processing and so on within a few miliseconds. In other words, NEON can deal with large amount of data - especially packed ones - In this tutorial, the focus will be on ARM 32-bit, and the examples are compiled on an ARMv6.

Introduction . ARM [3-9, 12-13] is the most dominant 32-bit embedded processor which is deployed in various embedded systems such as smartphones, tablets, vehicles, wearable devices, and IoT (Internet of Things) devices.

The article will also inform users which documents can be consulted if more detailed information is needed. NEON overview
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 algorithms such as video encode/decode, 2D/3D graphics, gaming & audio. Some ARM NEON example code that may help beginner.

extensions found in x86 processors. ARM has also defined a standard set of NEON vector types to be used with these intrinsics. For example, the arguments and return value of the vqadd_s16 intrinsic have a type of int16x4_t. These intrinsics and types are declared in the

I don't see anything like this in NEON though, so you may be out of luck. Often though you want to take a different approach, since branches are usually not desirable in optimised code. Ideally you will want to use the result of a SIMD comparison as a mask for subsequent operations (e.g. select different values based on mask using bitwise operations). All NEON instructions start with a v (for vector) and are easily distinguished from ARM's thereby.
