摘要 在普及计算领域中 ,终端设备所能够使用的资源是动态变化的 ,要求终端具有自适应处理能力 ,能够根据资源的变化作出相应的响应 .文中以嵌入式操作系统为基础 ,提出了终端自适应处理的体系结构 ,详细分析了采用控制理论的自适应算法 ,并对系统的平衡性、稳定性和灵敏性进行了分析 .文中以多任务系统为例 ,对系统的自适应性进行了实验说明 . In pervasive computing,the terminal's available resources will change dynamically and unpredictably.The terminal should be adaptive to changes in the supply of resources and respond to these changes.The paper proposes the adaptive architecture based on an embedded operating system,describes the adaptive algorithm using control theory,and analyzes the equilibrium,stability and agility of system.The paper demonstrates the adaptivity of the system according to a multi-task system.
