Programmable interface controller suitable for spanning clock domains

摘要

A programmable interface controller for transmitting data to an output device that is suitable in both fully synchronous systems and in systems that span clock domains. The illustrative embodiments comprise: receiving a plurality of field identifiers and an indication of an order by which each of the plurality of field identifiers is to be uniquely associated with each field in a sequence of fields; receiving a stream of data that comprises the sequence of fields and an indication of the boundary between successive fields in the sequence of fields; and processing each field in the stream of data in accordance with the field identifier uniquely associated with that field.
