Asynchronous (Clockless) CPU
Race conditions: now in hardware at the gate level!<p>A few questions<p>1. Could you call current SOCs asynchronous since they not only clock different blocks at different rates, but internally within a block subsections run at various rates?<p>2. Does variable clock rate deliver many of the benefits of async without the complexity? In other words how much more blood is there to squeeze from the async stone in the current world?<p>I doubt we'll see a competitive async chip anytime soon, but as CPUs continue to evolve perhaps we'll see the functional blocks broken up into smaller and smaller clock domains until it becomes difficult to tell the difference?
