RTA-OSEK provides a production real-time operating system suitable for applications in all areas of automotive ECU design. It implements the AUTOSAR-OS V1.0 (SC-1) and OSEK/VDX OS V2.2.3 standard and is fully MISRA compliant. An extremely small and fast runtime kernel is supplied for more than 20 popular microcontrollers, together with the Planner and Builder tools that are used to configure and analyze the operating system.

Using the Planner tool, the real-time deadlines of the application can be modeled and the runtime behavior can be predicted in advance. The Builder tool can be used to generate optimized data structures and code for the application. The RTA-OSEK module libraries are supplied with configurable instrumentation for RTA-TRACE. This allows a powerful and efficient development procedure to be used for real-time applications.

The low overheads and advanced timing control features of RTA-OSEK mean that it is ideal for powertrain and chassis electronics applications. Designers of body electronics modules appreciate the extremely low memory footprint and stack optimization features. Extensive consistency checks, together with automatically generated design checklists and template files, mean that all ECU software developers can benefit from using RTA-OSEK.

Certified OSEK-OS Solution
Each port of RTA-OSEK is independently certified. MISRA C compliance is built in as standard. Deploy software with complete peace of mind.

Planner-Tool
Use the RTA-OSEK Planner tool to prove that an application will meet its performance constraints before writing any code!
Solve problems before they become expensive.

Explore Application Boundaries
Find out how much extra functionality can be added to a system or minimize the clock speed.
Manage future up grades without expensive rewrites.

Optimize Stack Usage
Automatically fit the best set of priorities to task in an application and minimize the RAM requirements.

Graphical OSEK Configuration Tool
Create OS objects, such as tasks, ISRs, resources, etc. using a simple GUI.

Detailed Implementation Checklists
Speed up the development process using the automatic checklists of application API usage.

Application Build Environment
Automatically generates header files for each task and ISR in the application. Build checks catch OS configuration errors quickly.
