在英特尔® 架构的设备上优化 Android* 应用

在英特尔® 架构的设备上优化 Android*应用

概要介绍:

多年来英特尔®一直致力于帮助第三方软件商在 Windows 平台做性能和功耗的优化.软件优化后在性能和功耗上得到了大幅的改善。随着 Android*成为一个更大的市场平台,软件商都相应推出了自己在 Android 上的软件。然而,这些软件仍然有着比较大的优化空间.软件尤其是多媒体应用软件在性能和功耗方面提升空间非常大.事实上,同一款软件在同一 Intel 硬件平台上在 Window 上的性能甚至会远远好过在 Android*上的性能.这篇白皮书介绍了开发优化 Android 应用程序的一些工具和方法以及媒体应用程序的优化实例。这篇白皮书旨在面向  ISVs,  OEMs,  和其他技术相关人士。

  • Android Apps For The Intel Platform Learning Series: The Low-Power Design of Android Application

     

    Due to strict constraints on the system’s overall power consumption, low-power design, commonly known as power saving, is an important element of applications for mobile devices; in many cases it is a rigid requirement or the basis for survival. This chapter is organized as follows: first an overview of and introduction to low-power design, then a discussion of the Android power-control mechanisms, and finally a discussion of how to achieve the goal of low-power application design.

    Mobills Labs otimiza seu aplicativo para plataforma Intel® Atom

    Com mais de 700 mil downloads, o Mobills é um aplicativo para controle financeiro brasileiro muito reconhecido no Google Play. O aplicativo foi desenvolvido pela startup Mobills Labs e hoje está disponível para Android, iOS e Web. O aplicativo vem recebendo várias melhorias, principalmente para tablets Android com processadores da Intel®, onde são utilizados códigos nativos em C e C++ para otimizar e melhorar a performance nesses dispositivos.

    2 in 1 Tablet Mode Game Performance with Intel® Dynamic Platform and Thermal Framework (Intel® DPTF)

    We live in a world where mobility is king. Our on-the-go lifestyle demands small efficient devices, from smartphones to tablets and 2 in 1s. This is how we work and, quite often, play. Power efficiency is of paramount importance in the mobile world. Intel is focused on fast, powerful, and power-efficient technologies for mobile devices. However, this push for power-efficient processors can have unintended effects on game performance. One such feature that may impact game performance is the Intel® Dynamic Platform and Thermal Framework (Intel® DPTF).

  • What exactly is a P-state? (Pt. 1)

     

     

    A P-state is a voltage and frequency operating point

     

     

     

     

    What is a P-state?


    When someone refers to a P-state, generally only the frequency is talked about. For example, on my Intel® Core™ processor, P0 is 2.3 GHz, and P1 is 980 MHz. In truth, a P-state is both a frequency and voltage operating point. Both are scaled as the P-state increases. 

     

     

     

     

     

    Intel® System Studio - Multicore Programming with Intel® Cilk™ Plus

    Intel System Studio not only provides a variety of signal processing primitives via Intel® Integrated Performance Primitives (Intel® IPP), and Intel® Math Kernel Library (Intel® MKL), but also allows developing high-performance low-latency custom code (Intel C++ Compiler with Intel Cilk Plus). Since Intel Cilk Plus is built into the compiler, it can be used where it demands an efficient threading runtime in order to extract parallelism. Therefore it's possible to effectively introduce multicore parallelism even without introducing it into each of the important algorithms e.g., by employing a parallel pattern called pipeline. For custom code (e.g., code that's not reused via a library), one can rely (in addition to auto-vectorization) on an extended Array Notation incl. elemental functions (kernels) to explicitly vectorize at a higher level compared to ISA-specific intrinsic functions.

    How to use the Intel® Energy Profiler in Intel® System Studio 2015 on a Microsoft Windows* OS Target

    Introduction

    Intel® System Studio 2015 now contains an energy and power profiler called Intel® Energy Profiler. Using the Intel Energy Profiler allows you to collect sleep state, frequency and temperature data, and to find the software that is causing unwanted power use. This article provides an overview of the Intel Energy Profiler on a Windows* OS target.
