Altreonic is proud to announce the release of the version 1.1 of VirtuosoNext™, its high level yet very performant design and programming solution for trustworthy systems development. VirtuosoNext is derived from the formally developed network-centric and distributed OpenComRTOS who’s functionality is inherited. 

VirtuosoNext adds the capability to apply fine-grain time and space partitioning when the hardware supports it. VirtuosoNext provides safety measures to trap runtime errors without the system coming to a halt. The approach separates the code in a trusted zone (managed by the VirtuosoNext kernel) and an untrusted zone (executing application tasks). Contrary to traditional hypervisor approaches, the code size and performance penalty is minimal safeguarding the real-time response of a traditionally unprotected RTOS as standard priority based preemptive scheduling is maintained.

VirtuosoNext (protected mode) was initially disclosed in April 2015 This new release has also restructured the code resulting in even lower code sizes. On the ARM-M3, the VirtuosoNext kernel measures between 8 to 11.5 Kbytes. On the ARM A9, the kernel measures between 15 to 22 Kbytes.

Supported processors are ARM M3/M4/R4/R5 and the A7/A9/A15 processor family. The user has the option to enable the protection on specified processing nodes in his distributed or manycore target system. VirtuosoNext 1.1 will hence on make the previous and stable OpenComRTOS v.1.6 superseded as its functionality is integrated. The new services and improvements added with VirtuosoNext v.1.1 can be consulted in the attached files.
