SAFERTOS in Multicore Medical Devices
SAFERTOS enables dual and multicore/processor medical device designers to create seamless, mixed safety criticality designs quickly and efficiently. Due to its small size and its safety critical credentials, SAFERTOS is ideally suited for use on the primary core. This allows the system to boot and configure itself securely before enabling other cores that could run non-critical applications such as Linux to implement web servers and WiFi connections.
In a multicore environment, SAFERTOS is typically used on cores implementing safety critical functionality, or on cores providing monitoring/verification of the primary function. Due to its high safety classification, SAFERTOS can safely be used on both primary and monitoring cores, removing the need to use differential software.
