Heterogeneous multi-cores utilize the strength of different architectures for executing particular types of workload, and usually offer higher performance and energy efficiency. In this paper, we study a federated scheduling. Federated scheduling is a promising approach to schedule non-typed parallel real-time tasks, where each heavy task exclusively executes on a number of dedicated processors, while light tasks are treated as sequential sporadic tasks and share the remaining processors. We are the first considering federated scheduling for typed DAG tasks. In this paper, we first propose a method to show how to assign cores for heavy tasks. Second, we propose a response time analysis method for the light tasks. Experiments with randomly generated workload show that our proposed method are more precise than the only known global scheduling method of typed DAG tasks.

异构多核利用不同体系结构的优势来执行特定类型的工作负载，并且通常提供更高的性能和能效。在本文中，我们研究了联合调度。联合调度是一种有计划的方法，用于调度无类型的并行实时任务，其中每个繁重的任务专门在多个专用处理器上执行，而轻任务则被视为顺序的零星任务并共享其余的处理器。我们是第一个考虑类型DAG任务的联合调度的人。在本文中，我们首先提出一种方法来展示如何为繁重的任务分配核心。其次，我们提出了针对轻型任务的响应时间分析方法。
