Abstract

A system-level prototyping method has been developed for modeling the dynamics of concurrent real-time systems. This approach is based on higher-level statecharts, which embody object-based extensions to basic statecharts. To exemplify this method, a global communication mechanism is prototyped for a real-time multicomputer system that executes a single logical multitasking program. Since this prototype is intended to verify real-time concurrency logic, calibrate performance, and ensure safety, it includes a global virtual time base as a statechart subgraph. The prototyping process consists of capturing the system-level communication architecture in a higher-level statechart, and then translating it to an Ada multitasking program. A characteristic software architecture implicit in higher-level statecharts, known as a mutual agents architecture, appears to be suitable for an automated prototyping environment.<>

用于架构动态原型的高级状态图

提出了一种系统级原型方法，用于并发实时系统的动力学建模。这种方法基于高级状态图，它包含了对基本状态图的基于对象的扩展。为了举例说明这种方法，为执行单个逻辑多任务程序的实时多计算机系统设计了一个全局通信机制原型。由于此原型旨在验证实时并发逻辑、校准性能并确保安全性，因此它包含一个全局虚拟时基作为状态图子图。原型设计过程包括在高级状态图中捕获系统级通信体系结构，然后将其转换为Ada多任务程序。隐含在高级状态图中的特征软件体系结构，称为相互代理体系结构，似乎适合于自动化原型环境。
