White Paper: Options for Ensuring Data Traffic Priorities and Responsiveness in an Embedded Virtualized Device

Migrate Existing Embedded Designs with Intel® VT
Embedded virtualization paired with multi-core CPUs is paving the way for the consolidation of multiple dissimilar workloads within a single embedded device. Products such as those found in industrial automation, medical imaging, and networking or telecom applications are enjoying the benefits of increased compute capacity and decreased power consumption offered by multi-core CPUs.
A challenge that results from this consolidation is that products hosting multiple dissimilar workloads require new ways to accumulate content when connected to devices of dissimilar priorities. For example, the stream of information coming from an HMI terminal ought to be treated with different priority or latency than the stream of data that comes from remote position sensors.
No longer can a single OS provide all necessary functionality; multi-OS and OS separation are needed to build these products efficiently, and specific focus on the devices, and the priorities of the data generated by the devices contained within the equipment, is needed in order to maintain the required responsiveness of the product.
The data destined to a real-time operating system needs to be directed and prioritized with strict adherence to latencies and real-time requirements while data destined to general purpose guests have comparatively relaxed processing requirements.
