Automatic Implementation of Real-Time Object-Oriented Models and Schedulability Issues
نویسندگان
چکیده
The object-oriented design methods and their CASE tools are widely used in practice by many real-time software developers. However, object-oriented CASE tools require an additional step of identifying tasks from a given design model. Task identiication is usually performed in an ad-hoc manner using hints provided by human designers. In this paper, we present our ongoing research into schedulability-aware, automatic synthesis of multi-threaded implementation of a real-time object-oriented design. We present several feasible implementation strategies and architectures. We propose our approach to automatic implementation and address schedulability issues involved in our approach.

Schedulability Analysis for Automated Implementations of Real-Time Object-Oriented Models
The increasing complexity of real-time software has led to a recent trend in the use of high-level modeling languages for development of real-time software. One representative example is the modeling language ROOM (real-time object-oriented modeling), which provides features such as object-orientation, state machine description of behaviors, formal semantics for executability of models, and pos...
متن کاملDesigning for schedulability: integrating schedulability analysis with object-oriented design
There is a growing interest in using the object paradigm for developing real-time software. We believe that an approach that integrates the advancements in both object modeling and design methods, and real-time scheduling theory is the key to successful use of object technology for real-time software. Surprisingly many past approaches to integrate the two either restrict the object models, or d...
متن کاملExtending UML-RT for Control System Modeling
There is a growing interest in adopting object technologies for the development of real-time control systems. Several commercial tools, currently available, provide object-oriented modeling and design support for real-time control systems. While these products provide many useful facilities, such as visualization tools and automatic code generation, they are all weak in addressing the central c...
متن کاملScalable Real-Time System Design using Preemption Thresholds
The maturity of schedulabilty analysis techniques for fixed-priority preemptive scheduling has enabled the consideration of timing issues at design time using a specification of the tasking architecture and estimates of execution times for tasks. While successful, this approach has limitations since the preemptive multi-tasking model does not scale well for a large number of tasks, and the fixe...
متن کاملساختار دهی آنی داده‌‌های مکانی ورودی GIS با تأکید بر عارضه راه
An important issue in implementation of a GIS system is preparation of data to be entered in GIS. To produce spatial data for GIS using photogrammetric techniques, conventional method is to apply photogrammetric and GIS systems individually (off-line procedure). This approach is costly, time consuming and somehow unreliable due to the fact that 3D photogrammetric model is not available at the ...
