Hardware Virtualization In Microcontrollers

Look at any sufficiently advanced CNC machine or robot, and you’ll notice something peculiar. On one hand, you have a computer running a true operating system for higher-level processing, be it vision or speech recognition, or just connecting to the Internet. On the other hand, you have another computer responsible only for semi-real-time tasks, like moving motors, servos, and reading sensors and switches. You won’t be doing the heavy-lifting tasks with a microcontroller, and the Raspberry Pi is proof enough that real-time functions aren’t meant for a chip running Linux. There are many builds that would be best served with two processors, but that may be changing soon.

Microchip recently announced an addition to the PIC32 family of microcontrollers that will support hardware virtualization. This addition comes thanks to the MIPS M5150 Warrior-M processor, the first microcontroller to support hardware visualization.
