Abstract
Provided herein are systems and methods for performing dynamic adaption and correction for internal delays in devices connected to a common time-multiplexed bus. The methods allow devices to operate reliably at a higher bus frequency by correcting for inherent and unknown delays within the components and in the system by measuring the actual delays using multiple readings with the bus. Intrinsic noise and jitter are used to increase the precision of the measurements, thereby essentially using these uncertainties as self-dithering for increased measurement resolution. During adaption, delays may be adjusted in multiple step sizes to speed adaption time.
