摘要
Real-time embedded software today is commonly built using programming abstractions with little or no temporal semantics. This paper addresses this problem by presenting a programming model called programming temporally integrated distributed embedded systems (PTIDES) that serves as a coordination language for model-based design of distributed real-time embedded systems. Specifically, the paper describes the principles of PTIDES, which leverages network time synchronization to provide a determinate distributed real-time semantics. We show how PTIDES can function as a coordination language, orchestrating components that may be designed and specified using different formalisms. We show the use of this environment in the design of interesting and practical cyber-physical systems, such as a power plant control system.
