在英特尔® 架构的设备上优化 Android*应用
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。
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.
What you'll learn in this chapter are:
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.
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).
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.
The effect of reducing frequency

This article is essentially a collection of blogs I wrote on the same subject. The differences are simply a degree of formalism.
