ABSTRACT:
An apparatus and method for transferring units of information between clock domains. A respective set of N units of information is loaded from an output circuit in a first clock domain into a storage circuit in a second clock domain during each cycle of the first clock domain. Each set of N units is selected by the output circuit to include (1) units of information that have previously loaded into the storage circuit and that will not be output from the storage output from the storage circuit prior to the storage circuit being loaded with a subsequent set of N units of information, and (2) a complement number of units of information that have not previously been loaded into the storage circuit.
