Clockless Computing: The State Of The Art
Michael Stutz writes: "This article in Technology Review is a good overview of the state of clockless computing, and profiles the people today who are making it happen." The article explains in simple terms some of the things that clockless chips are supposed to offer (advantages in raw performance, power consumption and security) and what characteristics make these advantages possible.
That is NOT the reason they have not moved.
Designing something as complicated as a CPU without clocks is a daunting challenge. Keeping
everything in sync, removing race conditions,
keeping order of execution the same. There's a
lot of challenges in a clockless design.
