The automotive industry, including tier one suppliers and TCU vendors, increasingly looks toward the use of hypervisors. Hypervisors allow several system domains to run in different virtual machines (VMs) on a single processor through rigorous partitioning. Apart from cost savings, this provides a sound basis for safety and security. It also simplifies reuse of existing software components, saving time, cost and mitigating risk. The different parts of the system can be managed independently, allowing optimizations in terms of system response time and power consumption.
The processor that powers the reference platform, the NXP i.MX 8X is based on the Arm Cortex-A53 core, which additionally provides secure domain partitioning. i.MX 8X offers specific hardware partitioning with mechanisms to enforce isolation between the applications. This capability significantly simplifies the hypervisor development. Advanced hardware virtualization enables rapid deployment of multiple full-chip, domain-protected operating systems.
