As technology helps us more and more, we need to be able to trust it to operate safely and securely, whether in a medical device, a vacuum cleaner, an industrial robot, or a car. Functional safety (FuSa) is a specialized engineering discipline that focuses on keeping system failures from causing unsafe behaviors through active detection and either correction or mitigation.
The international standard ISO 26262: Road Vehicles is an adaptation of the FuSa standard IEC 61508 for automotive markets and provides a set of guidelines for FuSa engineers to manage safety at all levels through the development of a vehicle.
This standard is the basis for FuSa-certified Cadence® Tensilica® Processor IP products. Applications outside of the automotive market may rely on industry- or application-specific standards similarly derived from IEC 61508 for specific environments and use cases.
Certified Processor Packages and FuSa XOS configurations are currently available for the following Tensilica products:
Xtensa Processors for Functional Safety Applications with Full ASIL-D Compliance
Cadence® Tensilica® Xtensa® Processors with FlexLock are now certified for full Automotive Safety Integrity Level D (ASIL-D) compliance, with both ASIL-D systematic and ASIL-D random fault protection for use in Functional Safety (FuSa) applications.
