Apple has a history of silently changing chips/process in small quantities without telling anyone. AFAIR, they changed the soc inside one of the ipad generations a few years ago when going from 32-28nm. There was a while that the current ipad at the time came with one of two different socs, and there was no way to tell, except the newer soc had a longer battery life and the ipad ran cooler.
It would therefore not surprise me if some existing apple products out there are already shipping with a new soc.
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.
