Abstract

See full text

An apparatus and method are disclosed in which unrelated completion operations intended for a single destination (requestor) are coalesced to improve achievable data bandwidth. During transmission, the completion operations are collected and compressed into a single packet and transmitted along the link. At a receiving end of the link, the single packet is decompressed and the previously unrelated packets are returned to their initial state before receipt by the requestor. The method can be implemented in the root complex, end points, and/or switches, in the case of a PCIe implementation, but can also be applied to other protocols besides PCIe.
