MetaH Evaluation and Support Site MetaH is a language and toolset for developing reliable, real-time multiprocessor avionics system architectures.
Use the MetaH language to describe the interfaces and selected properties of software and hardware components (source modules, processor, devices) and then combine them into an overall integrated system.
Use MetaH tools for analyzing real-time schedulability, reliability, and partition integrity. MetaH also automates the system integration process, orchestrating the complies and links needed to combine the software pieces for loading onto the specified hardware configuration.
With MetaH, modeling and implementation are performed in an integrated and structured way, ensuring correctness of the application's interfaces, timing, and fault responses.
- integration of components from multiple sources
- semanitics for timing, reconfiguration, partitioning and software/hardware interfacing
- formal modeling and analysis
- targeting to a variety of avionics real-time execution environments
- tailoring of system executive for each application

Creating Evolvable, Embedded, Time?Critical Systems with UML and MetaH This tutorial will look at how to create embedded, time?critical systems that can evolve as requirements or technology change, using the Unified Modeling language (UML) and MetaH, an architectural design language, with a supporting toolset, for specifying, analyzing, and integrating computer control systems. MetaH (http://www.htc.honeywell.com/metah/) was designed by Honeywell for the specification of real-time, fault-tolerant, securely partitioned, dynamically reconfigurable multi-processor system architectures. We will look at the integration of MetaH and UML, the Object Management Group?s standard language for object?oriented software development.
Since MetaH was developed to meet the requirements of aircraft and missile avionics and flight control, it can be valuable in other embedded, time-critical applications where a highly integrated, rapidly evolvable approach is needed, such as robotics. Developers use MetaH to specify the code modules that form the application, the execution behavior of the application, the target hardware and software environment, and the allocation of the application to the hardware. The specification is then analyzed to determine whether the system is schedulable, reliable, and safe. The MetaH tools can generate the integrated code for the application components, an executive, and ?architectural glue?, all customized for the target hardware environment.
The Society of Automotive Engineers (SAE) is developing a standard Avionics Architecture Language using MetaH as a base. We will show an integration of UML and MetaH that will be proposed to SAE as the standard.
