Real-Time Multi-Tasking in Software Synthesis for Information Processing Systems

摘要

Software synthesis is a new approach which focuses on the support of embedded systems without the use of operating-systems. Compared to traditional design practices, a better utilization of the available time and hardware resources can be achieved, because the static information provided by the system specification is fully exploited and an application specific solution is automatically generated., On-going research on a software synthesis approach for real-time information processing systems is presented which starts from a concurrent process system specification and tries to automate the mapping of this description to a single processor. An internal representation model which is well suited for the support of concurrency and timing constraints is proposed, together with flexible execution models for multi-tasking with real-time constraints. The method is illustrated on a personal terminal receiver demodulator for mobile satellite communication.
