RTA-OS

RTA-OS builds on the experience gained with the RTA-OSEK real-time operating system, which has been established in the automotive industry for many years. RTA-OS supports the use of single and multicore microcontrollers and combines the full set of AUTOSAR functions with minimal runtime overhead. By virtue of its ISO 26262 certification for ASIL-D, RTA-OS can also be used for developing functions with strict safety requirements.

RTA-OS can be combined with RTA-RTE (AUTOSAR Runtime Environment generator) and RTA-BSW (AUTOSAR Basic Software) to create an AUTOSAR-compliant runtime platform. The operating system can also be used in a non-AUTOSAR environment equally well.

Work can begin even if the target hardware is not available, as RTA-OS is delivered with a Windows PC port to allow application software development in virtual environments on the PC.

Benefits

• Best-in-class processor and memory overheads
• ISO 26262 (ASIL-D)-certified operating system
• Automatically generates an optimized data structure for exact configuration adapted to the specific application
• Supports wide range of single and multicore microcontrollers
• Includes a virtual development environment on MS Windows
• Patented single-stack implementation, which typically reduces application stack space requirements by between 50% and 80%
• Supports all AUTOSAR configuration levels for controlling time response behavior and memory protection
• Features an simple-to-use intuitive graphical user interface
• Offers easy migration from OSEK OS using the OIL2XML conversion tool
• The code generated for the AUTOSAR operating system is smaller and faster compared to that used for RTA-OSEK despite the additional functionality
• Implements common standards

Supported standards

• AUTOSAR R 4.3, R4.2, R4.1, R4.0 and R3.x, including OS functions for multicore processors and memory protection
• OSEK*/VDX OS-compliant classes
• MISRA-C:2004
