Abstract

Raising the level of abstraction in system design promises to enable faster exploration of the design space at early stages. While scheduling decision for embedded software has great impact on system performance, it's much desired that the designer can select the right scheduling algorithm at high abstraction levels so as to save him from the error-prone and time consuming task of tuning code delays or task priority assignments at the final stage of system design. In this paper we tackle this problem by introducing a RTOS model and an approach to refine any unscheduled transaction level model (TLM) to a TLM with RTOS scheduling support. The refinement process provides a useful tool to the system designer to quickly evaluate different dynamic scheduling algorithms and make the optimal choice at an early stage of system design.

事务级模型中的RTOS调度

提高系统设计中的抽象层次，可以在早期阶段更快地探索设计空间。嵌入式软件的调度决策对系统性能有很大的影响，设计者希望能够在较高的抽象层次上选择合适的调度算法，从而避免在系统设计的最后阶段进行易出错且耗时的代码延迟调优或任务优先级分配等任务。在本文中，我们通过引入RTOS模型和一种方法来解决这个问题，该方法将任何未调度的事务级模型(TLM)改进为具有RTOS调度支持的TLM。该优化过程为系统设计者快速评估不同的动态调度算法并在系统设计的早期阶段做出最优选择提供了一个有用的工具。
