摘要

分层调度是一种支持在同一计算平台上集成独立开发的应用程序的有效方法。特别是,最近提出并分析了M-BROE框架,通过预留服务器实现的虚拟多处理器抽象,在共享资源存在的情况下,有效地支持多处理器平台上基于组件的开发。但是,没有解决将应用程序划分到虚拟处理器和定义保留参数的问题。本文通过提出一种设计方法来填补这一空白,该方法将应用程序划分为虚拟处理器,执行组件接口的合成,并将虚拟处理器分配给物理处理器。实验结果也给出了评估所提出的方法。

Partitioning and Interface Synthesis in Hierarchical Multiprocessor Real-Time Systems
Hierarchical scheduling is an effective approach developed to support the integration of independently developed applications on the same computing platform. In particular, the M-BROE framework has been recently proposed and analyzed to efficiently support component-based development on multiprocessor platforms through the virtual multiprocessor abstraction implemented by reservation servers, in the presence of shared resources. However, the problems of partitioning applications to virtual processors and defining reservation parameters were not addressed. This paper fills this gap by proposing a design methodology as an optimization problem for partitioning applications to virtual processors, performing a synthesis of the component interface and allocating virtual processors to physical processors. Experimental results are also presented to evaluate the proposed methodology.
