Towards Frame-based Source Code Generation for Heterogeneous Real-time Environments

This work focusses on the source code generation of task and communication patterns for different real-time operating systems. On the basis of reusable frames, an initial approach for implementing distributed applications will be presented. Thereby, distributed real-time systems can be mapped to the operating system framework Hyper Real-time Operating System (HyROS). In this respect, it is of great importance to cleanly separate functional from non-functional properties. Mapping different systems to HyROS can be achieved by using HyFrameLang, a language for frame operations and HyAppLang, an embedded domain specific language. Programming examples for HyFrameLang and HyAppLang are presented for task patterns of PXROS-HR and OSEK/VDX, representative real-time operating systems. Moreover, a short introduction on framing communication aspects is given.
