Write pipeline and method of data transfer that sequentially accumulate a plurality of data granules for transfer in association with a single address

摘要

A data processing system may include an interconnect and first and second components coupled to the interconnect for data transfer therebetween. The first component contains a write pipeline that includes an address register and a queue including storage locations for a plurality of data granules. In response to receipt of a plurality of data granules that are each associated with a single address specified by the address register, the queue loads the plurality of data granules into sequential storage locations in order of receipt. Upon the queue being filled with a predetermined number of data granules, the queue outputs, to the second component via the interconnect, the predetermined number of data granules at least two at a time according to the order of receipt. Thus, data transfer efficiency is enhanced while maintaining the relative ordering of the data granules.
