Easing automotive software migration: From discrete ECUs to Zonal Controllers in emerging EE architectures
....
One way to achieve FFI is by sandboxing each software component into virtual machines isolated by a separation kernel. Armv8-R supports this feature by means of real-time virtualization. Through using a hypervisor, or simpler separation kernel, on Armv8-R based processors, like Cortex-R52 and Cortex-R52+, it is possible to achieve FFI among multiple software workloads.
Therefore, Cortex-R52 and Cortex-R52+ processors offer an ideal platform for building zonal controllers that can be useful for deploying multiple software workloads, which are currently running on discrete ECUs, many of which are based on Arm Cortex-M processors. For more information on virtualization supported by Armv8-R, please refer to the Best Practices for Armv8-R Cortex-R52+ Software Consolidation.
