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 ...

Asynchronous, or clockless, logic–an alternative to standard digital circuits that avoids many of their problems–is beginning to look attractive for embedded designs in consumer electronics and mobile ...

Typical IC clocking schemes are under stress in complex chip/chiplet designs, where multiple compute elements may not be operating at the same frequency consistently. Some cores may be powered down to ...

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 ...

At a logical level, synchronous designs are very simple and the clock just happens. But the clocking network is possibly the most complex in a chip, and it’s fraught with the most problems at the ...

Understand how double-pumped, quad-pumped, and source-synchronous devices work, and you can capture the right data at the right time. High-speed digital buses continuously evolve. Not only are they ...

Lack of coordination between asynchronous resets and synchronous logic clocks leads to intermittent failures on power up. In this series of articles, we discuss the requirements and challenges of ...
