As part of the DECOS architecture, this paper presents a generic framework for gateways, which enable message exchanges across application subsystem boundaries in order to exploit redundancy and to coordinate the behavior of application subsystems. In the DECOS architecture, networks of different application subsystem can exhibit property mis matches, such as different protocols (e.g., CAN protocol...
Creating robust real-time embedded software is critical in combining the physical world with computing, such as in consumer electronics or robotics. One challenge is the complexity of dealing with time together with implementation details that often end up implicitly determining the temporal behavior of the program. In this paper we suggest deconstructing a program into two separate aspects, the functional...
Formal specification and verification are critical to the development of safe real-time and embedded systems, which have become increasingly complex. Real-time logic (RTL) has been used to describe the specification and safety assertion of real-time systems. However, the satisfiability problem for RTL, as well as other first-order logics, is undecidable. There exist already non-trivial fragments of...
In this paper, we address the problem of static scheduling and software synthesis for dataflow graphs with the symbolic model-checker NuSMV using a two-step process: first use model-checking to obtain a static schedule with the objective of minimizing the data buffer size, then synthesize efficient code from the static schedule with the objective of minimizing code size and performance overheads due...
