#2Just forwarded this off to my EE colleagues.
I'm for approaches that may be superior overall.

#3There doesn't seem to be any sign of recent activity on the asynchronous research center site affiliated with the article. Is anyone aware of currently active academic or industrial research groups in this field?

#4Asynchronous logic is significantly more power efficient, so it may be one approach to "save Moore's Law" (for one generation perhaps). But it would probably require some company that really cares about power efficiency, doesn't care about industry best practices, and is willing to risk hundreds of millions in R&D.

#5This reminded me of one of Gustafson's reasoning for change in how numerical computations are done - currently used principles of hw architecture result in hw wasting lots of energy and time, mostly in the process where numbers get from RAM to CPU and back. It seems more people already realize this, which is good. I hope to see some general purpose hw inspired by these ideas of efficient computation.

#6A few months ago there was another discussion here of an older article of his on the same topic [1].
Archive.org has some of their old FLEET architecture papers and slide decks: [2]

#7Handshake Technology:

Warning: Slightly commercial in nature. But some good information about how it works starting on page 4. Worth reading from there.

#8In the networking world Fulcrum built some very low latency switch chips used in switch routers using asynchronous logic. The Alta switch chip was the last of that generation.

Intel acquired Fulcrum and has not had a new product. One can speculate that they were acquired in part for their experience and tool to design asynchronous pipelines.
In the DSP world Octasic makes DSPs that use asynchronous desisns:

People have been poking at it for over 30 years now.
I'm scratching it up to "it's the future, and always will be ..."

The Fulcrum/Intel FM10000 was released but it didn't get much love.
