Sorry, Jon. Looking back I see you were talking about how fast one could drive GPIO pins.

You've mentioned floating-point performance in the past.

In my philosophy, Horatio, this is a perfectly acceptable requirement and I look forward to products from you and Peter. I accept as well that they may have to be tailored to specific ARM-based systems for the reasons just mentioned.
