Abstract:
1. An apparatus to provide data based in part on a justification command, the apparatus comprising: processor logic to selectively provide a justification command and data from an input signal; a clock source to provide a first clock signal, wherein the clock source selectively modifies a phase of the first clock signal in response to the justification command; and an elastic store device to selectively transfer the data based in part on the first clock signal, wherein the clock source comprises first, second, and third clock sources to respectively provide the first, a second, and a third clock signals; a transform device to modify the phase of the clock signal in response to the justification command, to update a phase account to account for a phase impact of the justification command, and to update the phase account according to an amount of clock signal phase shift adjustment; and a phase comparator to modify the phase of the second clock signal based on a phase comparison of the first and third clock signals, wherein the processor logic is to selectively provide the justification command in response to a relative value of the phase comparison and a threshold value, wherein the clock source is to selectively maintain a ratio of the first clock signal to the third clock signal as approximately one in response to the justification command.
