Abstract

In an MP-SoC environment, a customized run-time management should be incorporated on top of the basic OS services to globally optimize costs (e.g. energy consumption) across all active applications, according to constraints (e.g. performance, user requirements) and available platform resources. To that end, we have proposed a Pareto-based approach combining a design-time application mapping and platform exploration with a low-complexity run-time manager. This allows to alleviate the OS in its run-time decision making and to avoid conservative worst-case assumptions. In this paper, we focus on the characterization of the Pareto-based application specification, resulting from our design-time exploration. This specification is essential as input for our run-time manager. A representative video codec multimedia application, simulated on our MP-SoC platform simulator, is used as case study. For the resulting Pareto-based specification, both binary size and performance overhead is negligible

基于pareto的MP-SoC自定义运行时管理应用规范

在MP-SoC环境中，定制的运行时管理应该结合在基本的操作系统服务之上，以根据约束(例如性能、用户需求)和可用的平台资源，在所有活动应用程序中全局优化成本(例如能耗)。为此，我们提出了一种基于pareto的方法，将设计时应用程序映射和平台探索与低复杂性的运行时管理器相结合。这可以减轻操作系统在运行时的决策负担，并避免保守的最坏情况假设。在本文中，我们将重点关注基于pareto的应用程序规范的特征，这是我们在设计时探索的结果。作为运行时管理器的输入，该规范是必不可少的。本文以一个典型的视频编解码多媒体应用为例，在MP-SoC平台模拟器上进行了仿真。对于生成的基于pareto的规范，二进制大小和性能开销都可以忽略不计
