There's nothing "big-LITTLE" about a couple identical CPUs and a trip of graphics cores. Big-LITTLE is about a smaller CPU (maybe Cortex-A7) to offload a larger CPU (-A15). While big-LITTLE would be a good approach, I'm not sure I've seen any indication that was done in this chip. Separate on-chip graphics cores are standard design practice.
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.
