DEVICE, SYSTEM AND METHOD FOR COMMUNICATION WITH HETEROGENOUS PHYSICAL LAYERS

摘要

A device to process data packets for communication across PHY layers which are of different respective communication protocols. In an embodiment, the device includes a first protocol stack and a second protocol stack which are each for a PCIe™ communication protocol. The first protocol stack and a second protocol stack may interface, respectively, with a first physical (PHY) layer and a second PHY layer of the device. The first protocol stack and the second protocol stack may exchange packets to facilitate communications via both the first PHY layer and the second PHY layer. In another embodiment, the first PHY layer is for communication according to the PCIe™ communication protocol and the second PHY layer is for communication according to another, comparatively low power communication protocol.
