智能手机终端双操作系统间省电系统设计方案

随着移动通信终端性能的快速发展,智能手机的崛起导致便携式终端高性能和持久的矛盾愈演愈烈;同时,各层级低功耗技术的飞速发展也对终端省电系统设计提出更进一步的挑战。本文从嵌入式操作系统的角度,提出了一种基于智能手机终端双操作系统间的省电系统设计方案,并通过智能手机基带子系统和应用子系统操作状态设计及双系统间状态切换流程予以说明。

Power Saving System Between Double OS Based on Smartphone

With the rapid development of mobile communication terminal performance, smartphone rise led to the portable terminal＇s high performance and long lasting contradiction intensified. At the same time, all levels of low power consumption technology＇s development of terminal urge power saving system design face a further challenge. This paper proposes a power saving system design scheme between double OS（Operating System） ,which is a module in the embedded operating system, and explains this scheme through the design of sys- tem opterating state in BB（Base band） subsystem and AP（Application） subsystem, and sate switching process of double OS.
