The paper presents a design method for embedded control systems based on the mixed architecture that consists of both time-triggered processing and event-triggered processing. We divide a design process into functional design and behavioral design. We also apply aspect-oriented programming to realize the separated design. In the functional design, we(More)
The paper presents a distributed computing environment for embedded control systems with time-triggered and event-triggered distributed processing. We have already presented a time-triggered distributed object model and a time-triggered distributed computing environment for embedded control systems. However, there are many embedded control systems with(More)
—The paper presents a model transformation environment to transform a Simulink model to a UML model. The embedded control software development process consists of the control logic design phase and the software design phase. MATLAB/Simulink is widely used to build a controller model in the control logic design phase. On the other hand, UML is widely used in(More)
The paper presents a time-triggered distributed object computing environment for embedded control systems such as automotive control systems. The time-triggered architecture is suitable for hard real-time systems. We present a time-triggered distributed object model as an extension to the time-triggered object model that consists of objects periodically(More)
The paper presents a distributed real-time operating system (DRTOS) for hard real-time embedded systems such as automotive control systems. A real-time control application program is usually designed as a set of tasks that cooperate with each other through the mechanism of a real-time operating system. In a distributed embedded control system,(More)
