System for data transfer across asynchronous interface

摘要

A system for use in transferring data packets across different clock domains using an input data register for receiving a block of data packets with the input data register and a plurality of interface registers located in the first clock domain for transferring a block of data packets from the input register to a second clock domain in response to a request signal with the system prioritizing the transfer of multiple data packets within the block of data packets by length in order to transfer the longer word packets first and the shorter word packets last with the shortest word packets within the block bundled together and simultaneously transferring across an asynchronous interface.
