嵌入式分布实时系统自适应资源管理架构

Architecture of Self-adaptive Resource Management for Distributed Real-time and Embedded System

分析了开放嵌入式分布实时(Distributed Real-time and Embedded,DRE)系统的自适应资源管理需求,针对传统静态资源管理方法的不足,提出了一种面向开放DRE系统的自适应资源管理架构;该架构采用动态任务管理、实时资源分配和自适应控制三种关键技术,能够更加适用于开放、动态的环境,有效应对资源约束和资源状态、应用程序QoS的变化;提高系统性能和稳定性;屏蔽底层硬件资源的异构性,为上层应用提供统一的服务接口。

This paper analyzes the requirements of self-adaptive resource management for open distributed real-time and embedded（DRE） system,and presents an architecture of self-adaptive resource management for open DRE system aiming at the deficiency of traditional static resource management methods.This architecture is more applicable to open and dynamic environment since it adopts dynamic task management,real-time resource allocation and self-adaptive control technologies.It can handle resource constraints and fluctuations in system resource state and QoS of applications;improve system performance and stability;and shield heterogeneity of low-level hardware resources and provide unified service interfaces for up-level applications.
