Qualcomm's use of, and motivations for, using LLVM, to me are the most interesting aspects of the article.
It would seem, in general, that letting the front end, in broad use environments, be useful in dictating the hardware resources, architecture and even the instructions available.
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.
