What is electrical insulation tape officially for?
I've seen it used when cables start to fray and expose the internal wiring.

Why are relatively simpler devices such as microcontrollers so much slower than CPUs?
Also power (and therefore heat) increase more than linearly with frequency.

High performance CISC processors tend to issue way more instructions that simple embedded processors. They are doing a lot more work in parallel, so they are both more complex and faster.

I'm not worried about latency at the moment, just functionality. What do you mean by "self-routing?" (Sorry for the stupid question)
