面向智能手机的嵌入式实时操作系统

A Smart Phone-oriented Embedded Real-time Operating System

文章介绍了一种由中兴通讯自主设计的智能手机操作系统———SPOS。该系统基于单内核体系结构,其多任务实时内核提供对主流手机硬件平台和资源的支持,具有高效的动态电源管理、基于优先级的抢占式调度、快速启动、丰富的驱动程序以及良好的稳定性与操作性。为了更好地支持上层通信协议和应用软件的开发,该系统还提供了无线通信接口和应用程序框架。

This paper presents an embedded real-time hand phone operating system named SPOS （Smart Phone Operating System）, developed by ZTE Corporation. This system is based on a single kernel architecture supporting real-time multitask. It has remarkable advantages： supporting all the mainstream hand phone hardware platforms, highly efficient dynamic power management, priority-based preemptive scheduling, fast startup, diversified drivers, and excellent system stability and operation ability. For the development of upper layer communication protocols and application software, this system also provides wireless communication interfaces and application program framework.
