The Challenge is about ApplicationThe existing flourishing application ecosystem Google Play : ~ 500,000+ Apple App Store : ~ 590,000+ Windows Phone App : ~ 100,000+

However, can it benefit SmartTV user directly? When you install an application from mobile/tablet application market

to your SmartTV, what do you expect to happen? Often happen: exception,and can’t run; display issue; layout

issue; user interactive issue; not full features workable Rarely happen: run and play well Even it runs and plays well, do you think it is a real application

you want to play on the TV screen?

Optimization in HTML5 Optimizing DOM constructs for HTML5 tags <canvas> 2D bitmap graphics NEON optimized- libpixman, SKIA

<svg> 2D vector graphics NEON optimized- libpixman,SKIA feFilters optimized using SMP and NEON

Example: SVG 1.1 defines filters now sped up by ParallelJobs Turbulance 60-80% ConvolveMatrix 20-30% Morphonlogy 20-25% Lighting 10-20% [NEONized version takes this to 3X] Gaussian Blur 15% [NEONized version takes this to 4X]

<video><audio> NEON optimized : TheorARM, WebM VP8 and ffmpeg

CSS Parsing Redesigned CSS parser giving 5% speedup+

Added new RGB color parsing giving 30% speedup

NEON in open source Google WebM – 11,000 lines NEON assembler! Bluez – official Linux Bluetooth protocol stack Pixman (part of cairo 2D graphics library) ffmpeg (libav) – libavcodec

LGPL media player used in many Linux distros and products Extensive NEON optimizations

x264 – Google Summer Of Code 2009 GPL H.264 encoder – e.g. for video conferencing

Android – NEON optimizations Skia library, S32A_D565_Opaque 5x faster using NEON Available in Google Skia tree from 03-Aug-2009

LLVM – code generation backend used by Android Renderscript Eigen2 – C++ vector math / linear algebra template library Theorarm – libtheora NEON version (optimized by Google) libjpeg / libjpeg-turbo – optimized JPEG decode libpng – optimized PNG decode FFTW – NEON enabled FFT library Liboil / liborc – runtime compiler for SIMD processing DirectFB – Neon enabled s/w fallback

Ne10 Introduction Ne10 is designed to provide a set of common, useful

functions which have been optimised for the ARM architecture and NEON provide consistent well tested behaviour and that can be easily incorporated into applications

C and JNI interfaces are provided (JNI Not publicly available yet)

The library is modular; therefore the functionality that is notrequired within an App can be discarded

30

Ne10 - Routines

Images and Video•Image processing•Color conversion•JPEG/JPEG2000•Video Coding•Ray-Tracing/Rendering

Communications& Signal Processing

•DSP•Audio Coding•Speech Coding

Data Processing•Data Compression•Cryptography•String Processing•Matrix/Vector Algebra•Data Integrity

Targeting three main categories of functions

31

Ne10Droid – The App in actionNe10Droid is a benchmarking Android App that uses Ne10Routines are written using VFP in C, VFP in Assembly and NEON.Example routines:arm_result_t normalize_vec2f(arm_vec2f_t * dst, arm_vec2f_t * src, unsigned int count);arm_result_t normalize_vec3f(arm_vec3f_t * dst, arm_vec3f_t * src, unsigned int count);arm_result_t normalize_vec4f(arm_vec4f_t * dst, arm_vec4f_t * src, unsigned int count);

32

Ne10 - Future plans

Dual licensing under both Apache 2.0 and MIT as to be compatible with GPLv2.

Ne10 will include DSP functions (Think Zephyr and OpenMAX)

working on using Ne10 to optimize Box2D and the popular game engine

We want your input on future functionality and participation!
