WITTENSTEIN high integrity systems

WITTENSTEIN high integrity systems (WHIS) is part of The WITTENSTEIN Group.

The WITTENSTEIN Group was established in 1948 and has grown into a stable and mature global technology company with a focus on high end mechatronics systems. In 2014 the WITTENSTEIN Innovation Factory was officially opened, an 18,000 square meter investment in future growth housing mechatronic projects from concept to finished product.

With a presence in more than 40 countries, more than 2600 employees worldwide, and a turnover in 2017/18 of over 438 Million USD, WITTENSTEIN continues to flourish in highly demanding markets.

Originally part of the aerospace group, WHIS is the Group’s centre of excellence for high integrity and safety critical embedded systems design. WHIS is first and foremost a Safety Engineering Company. This is a key differentiation in the RTOS market as WHIS have direct experience developing safety critical applications, such as, flight control systems, implanted active medical devices, and sub sea oil and gas platforms. Consequently, WHIS engineers have a profound knowledge of safety critical development, and high integrity development life cycles are well and truly institutionalised within company working practices. Today our primary focus is the development and supply of mission and safety critical RTOS.

The SAFERTOS Story

Since 2007 the primary focus has been the development and supply of mission and safety critical RTOS and middleware components. WHIS engineers took the FreeRTOS functional model, exposed it to a full HAZOP, identified all areas of weakness within the functional model and API, mitigated all areas of weakness, and took the resulting requirements set through an IEC 61508 SIL 3 development life cycle, the highest possible for a software only component.

In doing so we created SAFERTOS®: the renowned safety certified RTOS that delivers superior performance and safety critical dependability whilst consuming minimal resources. The success of these endeavours can be judged by the fact SAFERTOS was independently certified on the first iteration by TÜV SÜD back in 2007.

SAFERTOS has continuously evolved since its initial creation and the list of supported processors and toolsets is constantly expanding. SAFERTOS includes, among other features:

  • Task Isolation and Separation;
  • Ultra-Low Power Mode;
  • OSEK API Wrapper;
  • A range of Safety Plugins.

Our Relationship with FreeRTOS

WHIS leverage RTOS technology from FreeRTOS.org®, the market leading embedded real time operating system downloaded every 120 seconds on average in 2017.

Richard Barry created FreeRTOS while an employee at WHIS. WHIS engineers worked closely with Richard, providing a safety critical upgrade to FreeRTOS, SAFERTOS, and the flexible commercial licensing, training, and support that FreeRTOS users needed.

Strategic Business Alliance with AWS

In 2017 Amazon Web Services (AWS) announced stewardship of FreeRTOS, introducing Amazon FreeRTOS, part of the AWS Edge to Cloud IoT offering. This enables greater investment in the FreeRTOS Kernel to the benefit of developers and manufacturers bringing new edge devices to market.

Now that FreeRTOS is stewarded by AWS, nothing has changed. WHIS engineers continue to be experts in the use of FreeRTOS, providing tailored service solutions and WHIS continue to be the market leaders when it comes to professional FreeRTOS services.
