That's a very good question. Asynchronous design is really cool, but has never gone anywhere that I know of.

"One interesting experiment was using a hair
dryer to heat up the chip. As the temperature
rose, one could see the oscillation period stretch
on the oscilloscope, and then shrink again as the
dryer was removed"
- throwaway81523 5y agoIn the old days there were some substantial asynchronous computers including the original (KA) PDP-10. I think the method is not used much these days. The GA144 is not really asynchronous. Each core is clocked by its own little ring oscillator, if I understand it right
- buescher 5y agoI didn't know that about the KA PDP-10 nor had I looked that deeply into the GA144. Thanks.
