实时系统和应用程序变得越来越复杂，并且通常包含多个通信任务。单个任务的管理很好理解，但具有不同时序特征的通信任务的交互却不太好理解。我们讨论了几种通过保留内存缓冲区（可能通过实时网络互连）的代表性任务间通信流，并提出了 RAD-Flows，这是一种用于管理这些交互的模型。我们提供的证明和仿真结果证明了RAD-Flows的正确性和有效性，使系统设计人员能够根据交互任务的特征确定所需的内存量，并保证整个系统的实时运行。
Real-time systems and applications are becoming increasingly complex and often comprise multiple communicating tasks. The management of the individual tasks is well-understood, but the interaction of communicating tasks with different timing characteristics is less well-understood. We discuss several representative inter-task communication flows via reserved memory buffers (possibly interconnected via a real-time network) and present RAD-Flows, a model for managing these interactions. We provide proofs and simulation results demonstrating the correctness and effectiveness of RAD-Flows, allowing system designers to determine the amount of memory required based upon the characteristics of the interacting tasks and to guarantee real-time operation of the system as a whole.
