摘要：Systems of and methods for processing data for communication between asender and a receiver are described. In one embodiment, the phase of a first clock is usedto select between first and second portions of data from the sender. The selected data isthen synchronized, for communication to the receiver, to a second clock having afrequency which is an integer multiple of that of the first clock, wherein the integermultiple is two or more. The first and second portions of the data may be provided tothe same output pins in this embodiment for communication to the receiver. In a secondembodiment, first and second portions of data from the sender are clocked in using firstand second edges, respectively, of a first clock. The first and second edges have a first
polarity if a first pre-determined mode is in effect, and have a second polarity if a secondpre-determined mode is in effect. Data derived from the clocked in data is thensynchronized, for communication to the receiver, to a second clock. In a third
embodiment, data from the sender is clocked in using a first clock. The clocked in data isthen transformed responsive to a pre-determined mode selected from a plurality ofpossible modes. The transformed data is then synchronized, for communication to thereceiver, to a second clock. In a fourth embodiment, a first clock is provided which isdelayed relative to a second clock by a pre-determined amount. Data is then clocked outfor communication to a receiver using the second clock, and clocked in for communicationback to the sender using a third clock derived from the second clock. Data derived fromthe clocked in data is then synchronized to the first clock.
