Asynchronous Digital Design by Fulcrum

Fulcrum Microsystems developed a clockless semiconductor design methodology. Which allows them to design processors that run much faster than clocked chips and with lower power.

Back in 1994, near the end of the digital design course I took in university, the professor introduced the class to asynchronous design. Our professor showed us some tricks for solving simple problem with asynchronous logic, but told us that the technique wasn’t feasible for large scale design at the time, because it was terribly complicated with race conditions. It seems Fulcrum has solved the problem, and even designed some rather complex chips with it.

They raised $20 million on Monday.
