许多 DSP 应用涉及高采样率,因此需要尽可能使用静态调度程序。然而,静态调度的构造通常仅限于适合同步数据流模型的应用程序。在本文中,我们将循环静态数据流作为模型来描述具有周期性变化行为的应用程序。我们给出了循环静态数据流图的静态调度存在的必要和充分条件,并展示了如何构造这样的调度。视频编码器的示例用于说明循环静态数据流对于现实 DSP 系统的重要性。
The high sample-rates involved in many DSP-applications, require the use of static schedulers wherever possible. The construction of static schedules however is classically limited to applications that fit in the synchronous data flow model. In this paper we present cyclo-static data flow as a model to describe applications with a cyclically changing behaviour. We give both a necessary and sufficient condition for the existence of a static schedule for a cyclo-static data flow graph and show how such a schedule can be constructed. The example of a video encoder is used to illustrate the importance of cyclo-static data flow for real-life DSP-systems.
