ARM announced an embedded version of its ARMv8 architecture that will add virtualization and lightweight Linux support to the next of generation Cortex-R processors. The ARMv8-R architecture is 32-bit, but borrows features from the 64-bit ARMv8-A such as hardware-based virtualization and a more advanced MPU, enabling safety-critical embedded applications like automotive computers to run RTOSes, bare metal code, and Linux and Android on a single processor.
