"Our computer is also asynchronous, meaning that there is no global clock controlling the computer. Rather, the data is accompanied by a clock signal as it flows around the computer, which means we only need to focus on local but not global timings of the computer."
I'm not sure that it qualifies as clockless but according to https://en.wikipedia.org/wiki/Asynchronous_circuit#Asynchron... it does.
BTW, congratulations to the authors of all of this. It's a huge achievement.
