This one is worth a quick read. Doesn't provide specific answers (the best software system depends on your application) but the discussion on using multi-core to save power vs a smaller single core processor was interesting to me. Maybe there will be a good market for small, multi-core MCUs if there are enough power saving modes included.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
