Method and apparatus for stabilized data transmission

摘要

Data can be accurately transmitted between two subsystems even if the clock skew between the two subsystems is larger than one clock cycle by the method of the invention. In one embodiment data is loaded into N state devices in the sending subsystem while the receiver recovers data from the sending state devices in rotation with an N input multiplexer. Another embodiment forwards a clock signal from the sending subsystem along with a data vector of N state signals for recovery by a pair of state devices capturing data on the rising and falling edges of the forwarded clock. A further embodiment achieves double bandwidth by forwarding two clock signals.
