Real-Time without Clocks?
For the last 20 years digital design has been based on the use of a central
clock, but it hasn't always been so, and it may not always be so in the
future. Where ultimate power-efficiency, performance or electromagnetic
compatibility are required, the clock may be the wrong answer. Recent work
within the OMI and elsewhere has pointed the way to a future where VLSI
devices can more readily be designed without clocks, and the advantages of
so-doing are becoming increasingly apparent.
