On the other side of the spectrum there is also a whole bunch of heavily specialised architectures on a mass market - microcontrollers, DSP (think Hexagon and alike).
OTOH, GPUs are interesting in a sense that they're not confined in any backward compatibility considerations, and therefore this is an area where most of the architectural innovation is going to happen.
- hga 12y agoGreat, DSPs are a very good additional example. Microcontrollers aren't, as I'm defining this, because of their simplicity and small die sizes targeted at huge natural volumes.
- sklogic 12y agoMid-range microcontrollers is actually where the Forth chips thrive, so I would not be so sure.
- hga 12y agoHeh, here I'm going to cheat and say "Forth is sufficiently magic that its success here is the exception that proves the rule!" I'm very impressed by it. Not my cup of tea, Lisp is, then again they have more than a little bit in common (or so I thought when someone explained Forth to me in the mid-80s).
