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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
