Functional Safety related products
SAFERTOS is a pre-certified safety Real Time Operating System (RTOS) for embedded processors. It delivers superior performance and pre-certified dependability, while utilizing minimal resources.
WHIS’s extensive Safety Critical design experience has made certifying SAFERTOS integrated within a product an easy and hassle-free process.
Contained within the Design Assurance Pack is the all-important Safety Manual. The Safety Manual explains exactly how to install and integrate SAFERTOS into your development environment. Following the concise instructions will also generate the evidence that is required by your auditors to confirm that the process has been followed correctly. This removes the need to retest SAFERTOS on your target hardware, and provides a solid dependable platform for your development.
In many safety critical applications, the Real-Time Operating System is the most critical component. The RTOS not only schedules the functionality of the software, it also schedules the operation of Safety Monitors and Safety Functions. The RTOS is frequently used to isolate safety critical code, ensuring it can operate without interference from other tasks. A failure in the RTOS will most likely compromise the Safety Case of the complete system.
SAFERTOS has been designed specifically for the safety sector, and the deterministic priority-based scheduling is the primary safety requirement. Every effort has been made to ensure that deterministic behavior is maintained. To ensure this SAFERTOS has been independently certified many times on numerous platforms, to IEC61508-3 SIL3 and ISO 26262 ASIL D, the highest possible SIL level for a software only component.
