This article describes emerging trends in synchronizing digital ICs and shows how process scaling, rapid increases in clock frequencies, and demand for lower power dissipation will affect the choice ...

Synchronous interfaces involve a single clock domain and are relatively easy to design. However, at times, it is advantageous and necessary to have an asynchronous interface between peripherals for ...

The synchronous vs. asynchronous design debate erupts every now and then, usually when a vocal minority swears by asynchronous design, often claiming that asynchronous design delivers higher ...

Power-supply design becomes complicated when you’re faced with multiple conflicting specifications. One example is the design of a double-data-rate (DDR) memory supply for an automotive environment.

In an era when power has become a fundamental design constraint, questions persist about whether asynchronous logic has a role to play. It is a design style said to have significant benefits and yet ...

As system-on-chip (SoC) designs grow larger, designers must grapple with serious global timing problems, the effect of wire loading and timing delays and the performance hit associated with supporting ...

Combining the advantages of permanent magnet and induction motors, new synchronous reluctance motors (SynRM) offer potentially breakthrough technology for variable speed drive (VSD) and motor packages ...

Power supplies that use diodes to rectify an ac voltage to obtain a dc voltage must deal with inherent inefficiencies. A standard diode or ultra-fast diode can have a 1-V forward voltage or higher at ...

A lack of suitable design tools and the dominance of a design culture favouring synchronous design are the factors limiting the broader use of asynchronous, or clockless, technology in chips.
