Abstract:
ARM devices are proliferating the mobile and embedded market segments, and with the introduction of Virtualization Extensions (ARMv7-A), and the latest 64-bit architecture changes (ARMv8), ARM is expected to expand further in the networking and server markets. At the same time, Mixed-Criticality use cases for In-vehicle (IVI) and In-flight (IFI) infotainment are of increased interest, where a feature rich Operating System (OS) is required for multimedia applications, while at the same time legacy real time operating systems are still needed for time critical applications. In this paper, we propose and test a Dual-OS environment for Mixed-Criticality systems using ARM devices, by exploiting latest architecture changes and software advancements. The technologies tested and covered in this paper, which enable a Dual-OS environment, include the TrustZone Security Extensions, ARMv7/v8 Virtualization Extensions, as well as the ARM Trusted Firmware (ATF) software infrastructure. Feasibility tests and latency/performance metrics were acquired on ARMv7/v8 platforms including Versatile Express and the Juno development boards.
