OpenComRTOS release v.1.4 - with Safe Virtual Machine for C.

Altreonic is new releasing v.1.4 of its breakthrough formally developed network-centric OpenComRTOS suite. While the visual development environment was enhanced to make multi-processor developments even easier, v. 1.4 now has the Safe Virtual Machine (SVM) for C fully integrated and the RTOS itself has now fully distributed support for priority inheritance for easier resource management. The latter is a pre-condition for lower power consumption and better predictable real-time behaviour at the application level.

Product Overview

Altreonic offers two main product lines in conjunction with services. A short overview:

1. "VirtuosoNextTM" is composed of following integrated development tools:

"VirtuosoNextTMis a next generation RTOS that is API compatible with OpenComRTOS, who's kernel is integrated. It provides fine-grain Time and Space Partitioning. The result is the protection that is offered by classical Time and Space Partitioning schemes but with the responsiveness and small code size of a dedicated RTOS. The user has the option to enable or disable protection on specific nodes (if the hardware supports it). 

"VirtuosoNextTM" is a network-centric RTOS, developed using formal methods. It supports from small microcontrollers to widely distributed networks of processing nodes, including nodes that run legacy OS like Windows or Linux. VirtuosoNextTM is the first network-centric RTOS that support heterogeneous systems in a transparent way.

Thanks to its formal development, it has unique properties like small code size, scalability, safety, portability even allowing developers to create their own services. It comes with the Visual Designer development environment allowing a graphical definition of the application and powerful tracing tools to profile the events in the system. While customers can do their own ports, ARM (Mx/Rx/Ax), Texas Instruments C6678, MicroBlaze, Leon3, PowerPC, XMOS, NXP CoolFlux DSP and MLX16 are available for specific boards. A typical code size is between 5 to 22 KiBytes. Altreonic offers porting and customisation services.

The "RTOS Qualification Package" is an optional component to the Open Technology License. Delivered as a GoedelWorks project, it gives detailed documentation and evidence for Qualification/Certification purposes with full test coverage and detailed traceability from top level Requirements till source code.

"Visual Designer" is a Visual programming and development environment for developing and simulating real-time embedded applications. It allows to define in a visual way the target's topology (from single processor to heterogeneous networks) as well as the application diagram. Template code is generated so that the developer only has to provide the algorithmic code. Applications can be simulated first on a Windows or Linux platform and then run on the target just by recompilation. It also has some powerful debugging tools:

  • "Event Tracer". It allows to analyse the scheduling and interprocessor communication in a graphical way.
  • "System Inspector": it allows to read out the status of any processing node at task level.

VirtuosoNextTM also offers dynamic code loading and execution, independently of the target processor. This capability is offered thanks to our SVM, short for "Safe Virtual Machine for C": very small (around 3 KiBytes), it allows to load and execute binary compiled C code tasks that has full access to the underlying RTOS services.
