Mode switch handling for the ProCom component model

Component-Based Software Engineering has been deemed a suitable technique for the development of complex embedded systems, as component reuse makes it easier to manage software complexity. Another way of reducing software complexity is by partitioning system behavior into different operational modes. Such a multi-mode system can change its behavior by switching between modes. For a multi-mode system built by components, a challenge is its mode switch handling. In this paper, a novel approach is presented to integrate our mechanism for handling mode switch (the Mode Switch Logic), in ProCom, which is a component model designed for the development of real-time embedded systems. The outcome is a slightly extended version of ProCom which not only supports the development of multi-mode applications, but also is able to handle mode switch.
