Abstract:
1. A data requestor for obtaining requested data from a synchronous data source, the data requestor transmitting for reception by the data source an original clock signal and an original control signal, which is representative of a data request, the data source receiving a delayed version of the original clock signal resulting from a delay in a clock signal path between the data requestor and the data source and a delayed version of the original control signal resulting from a delay in a control signal path between the data requestor and the data source, the data requestor comprising: a skewed clock signal generator adapted to generate a skewed clock signal that is substantially equivalent to the delayed version of the original clock signal, wherein the skewed clock signal generator includes means for transmitting the original clock signal for reception by the input sampling module over a signal path having a delay that is substantially equivalent to the delay of the clock signal path; a skewed control signal generator adapted to generate a skewed control signal that is substantially equivalent to the delayed version of the original control signal; and an input sampling module receiving the skewed clock signal and the skewed control signal and being adapted to sample, using the skewed clock signal and the skewed control signal, a data signal to obtain the requested data, wherein the data signal is representative of the requested data and is provided by the data source based at least in part on the delayed versions of the original clock signal and the original control signal.
