Abstract

See full text

Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with a shift register with a dynamic entry point, which may particularly useful for aligning skewed data. The dynamic entry shift register typically includes a series of storage elements, with multiplexers distributed between the storage elements. Each of the multiplexers is configured to select between: (a) the output signal of a previous storage element, and (b) the input signal. A control is configured to configure the multiplexers for a data signal applied as the input signal to induce an appropriate delay of the data signal as the output signal. The dynamic entry shift register can be scaled to accommodate a longer delay while still using only 2:1 multiplexers between stages in the dynamic entry shift register(s).
