"The first two versions of PCIe used 8b/10b encoding, and thus had lower processing overhead."
"Version 4.0 will use the same 128b/130b encoding..."
I was under the impression that going to 128b/130b was a rather significant reduction in overhead compared to 8b/10b or is this referring to the scrambling/descrambling that is applied to the data? After all the 2 bits in an 8b/10b encoding is 20% while 128b/130b is 1.5%.
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.
