"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%.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
