Wittenstein: SafeRTOS SIL3 Compliant RTOS available for Texas Instruments SIL3 Compliant MCU

The combination of High Integrity System's SafeRTOS kernel and TI's TMS570 ARM Cortex-R4F transportation and safety MCU affords designers a greater level of simplicity when creating and validating safety critical devices.

TI developed the TMS570 MCUs for use in safety related applications. Target applications include ABS, electronic power systems, battery management and radar driver assistance.

SafeRTOS is a small, robust real-time operating system designed for safety critical applications and is supplied with an independently validated certification pack to speed certification in IEC61508 and related standards in transportation, nuclear, industrial and medical applications.

TÜV SÜD first certified the operating system's mature design process in 2007. SafeRTOS offers a low risk approach and brings the benefits of off-the-shelf software to applications with safety implications or certification requirements. Exida has independently certified the TI TMS570 development process and safety concept.

The small, efficient kernel uses less than 10k flash and a few hundred bytes of RAM. It is supplied with design assurance packs tailored to meet IEC 61508 SIL3, FDA510(k) Class III and EN62304.

Combining soft and hardware that have both been developed to meet the certification needs of safety critical applications is a leap forward for the industry, said the head of marketing at High Integrity Systems, David Brook. The TI chip and HIS software have been developed specifically with the objective of being deterministic, verifiable and able to meet certification requirements.
