3.2.2 Asynchronous Techniques: GALS
The increasing demands of mobile devices create several problems for system design and
integration. Challenges like the integration of complex systems, timing closure including
clock generation and control, system noise characteristic, and power consumption for
mobile applications, in particular wireless devices.
Most digital systems designed today operate synchronously. One signifi cant challenge is
the generation of the clock tree. The clock tree in complex digital systems includes clock
gating supporting circuitry, clock dividers ...
