一种支持可重构混成系统的操作系统设计与实现

可重构硬件和指令集处理器构成的混成系统兼有运算速度高和编程灵活的优点,是近年来学术界研究的热点.已有的面向该类系统的操作系统由于受到传统抽象模型的制约,不能充分发挥可重构硬件的优势.文中在分析该类系统对操作系统的需求和已有运行模型缺陷的基础上,提出了一种基于服务体/执行流模型的操作系统SEF-OSHRS.它具有统一的系统对象抽象和通信接口,并可支持控制流的直接转换,因而能充分发挥混成系统的优势.文中详细介绍了该操作系统的基本抽象、系统结构和运行方式,并通过实验结果说明了该系统的可用性和高效性.

An Operating System for Hybrid Reconfigurable Systems: Design and Implementation

Hybrid systems that are composed of reconfigurable hardware and instruction set processors can achieve high performance as well as flexible programmability simultaneously.However the existing operating systems(OS)cannot fully utilize the reconfigurable computing resources in such systems.By exploiting a novel OS construction model SEFM(Servant & Execution-Flow Model),this paper presents an OS named SEF-OSHRS,which has a uniform system object Abstraction model and inter-servant communication interface.SEF-OS...
