95% -- I'll take that! Your point about extra resources, though, is quite valid, Brian. Any embedded instrument will consume FPGA resources; there is truly no free lunch.
I will say that we rarely see this issue in practice, as we tend to "fill-in-the-gaps" of left over LUTs rather than causing a re-partioning of the design. Still, it is an important point.
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.
