“It’s done in hardware so it’s cheap”. Yossi writes -
This is one of these things that look very obvious to me, to the point where it seems not worth discussing. However, I’ve heard the idea that “hardware magically makes things cheap” from several PhDs over the years. So apparently, if you aren’t into hardware, it’s not obvious at all.
So why doesn’t “hardware support” automatically translate to “low cost”/”efficiency”? The short answer is, hardware is an electric circuit and you can’t do magic with that, there are rules. So what are the rules? We know that hardware support does help at times. When does it, and when doesn’t it?
