Creating a safer, greener, more secure future.

Arm and WITTENSTEIN high integrity systems Work Together for the Advancement of Safety Critical Embedded Systems

WITTENSTEIN high integrity systems (WHIS) and Arm continue to collaborate on the advancement of functional safety for embedded systems. Arm have invited WHIS to be part of Its Functional Safety Partnership Program with their safety critical RTOS, SAFERTOS®. SAFERTOS and Arm form a winning combination for functional safety applications.

WITTENSTEIN high integrity systems (WHIS) and Arm have a long history of working together, with many millions of SAFERTOS implementations on Arm cores. Arm have invited WHIS to join the Arm Functional Safety Partnership Program, a carefully curated portfolio of industry leading companies with a proven track record in functional safety development. This partnership means that WHIS and Arm will continue to work closely together, delivering highly optimised software packages for safety critical environments.

WHIS have been specialising in safety since 2006, and have a long history of supporting Arm based environments, including the Arm Cortex-M, Cortex-R, and Cortex-A families, as well as offering integration for Arm Trust Zone. A wide variety of SAFERTOS® demos on Arm architectures are available for download from the WHIS download centre.

SAFERTOS is a pre-emptive safety critical RTOS that delivers unprecedented levels of determinism and robustness to embedded systems, whilst using minimal resources. It’s used internationally across a range of safety critical applications and is renowned for its high quality. A key advantage of SAFERTOS is the upgrade path from FreeRTOS to SAFERTOS. Engineers can prototype using FreeRTOS, and convert to SSAFERTOS at the start of formal development.

SAFERTOS is the perfect choice for Functional Safety projects as it is available pre-certified by TÜV SÜD to ISO 26262 ASIL D and IEC 61508 SIL 3. WHIS have a 100% success rate certifying SAFERTOS and are currently working with some of the biggest companies in the world on their safety critical projects.

“SAFERTOS has been performing in Arm environments since its creation, providing an ‘out of the box’ product that requires no retesting on the target hardware.” Says Andrew Longhurst, Managing Director of WHIS. “Using SAFERTOS in your Arm environment is a winning combination if your next project is for a safety critical application.”

SAFERTOS and the WHIS profile can be found in Arm’s Functional Safety Partner Program
