It will be quite an interesting battle between x86 and ARM. I could certainly see Intel eventually getting down to the tablet and smart phone levels of power consumption and cost - or at least close - but I can't see them going below that.
The cut off point between "microcontroller-based embedded systems and sensor nodes" and an IOT device will be up for a debate that will influence this market quite a bit. For example, if a device consists of a small 32-bit ARM and a WiFi module, with a total bill of material cost of $15.00, is it too small to be considered IOT.
What if that device is connected to your garage door so you can check status and open and close it remotely? I'd call that an IOT device even though it would quite likely be possible with 8 or 16 bit MCUs.
if x86 only focus only server and high margin, it is going to be another IBM.
Leaving $5-$10 chips on the table is the most dangerous things for x86.
MIPS and PowerPC will not penetrate unless management drastically come up with some real value...
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.
