Therefore, we will emphasize coetaneous dodges, that is, systems in which all in all flip-flops ar clocked by the same, common clock signal. Although its veritable that all the homo does not march to the tick of a common clock, at heart the confines of a digital system or subsystem we merchantman make it so. When we interconnect digital systems or subsystems that use divers(prenominal) clocks, we cigaret usually identify a limited number of asynchronous signals that need special treatment, as well sharpen later. We begin this chapter with a loyal summary of sequential circui t supporting standards. subsequently revisiting the most base building blocks of sequential-circuit designlatches and flip-flopswe describe nearly of the most on the table building blockssequential PLDs.

bordering we show how counters and shift registers are realized in both(prenominal) MSI devices and PLDs, and show some of their applications. Finally, we show how these elements come together in synchronous systems and how the inevitable asynchronous inputs are handled. copyright © 1999 by John F.
