Abstract
A Compute Express Link™ (CXL) over Ethernet (COE) station is provided to bridge a CXL fabric and an Ethernet network to allow for efficient native memory load/store access to remotely connected resources. The COE station supports CXL and Ethernet traffic through its CXL interface, scheduler/packers, decoders, VOQs and VIQs by adding COE tags to Ethernet frames. In CXL controller mode, the CXL controller drives the VOQs. In Ethernet mode, the COE module drives the VOQs, and interacts with the MAC sublayer and the PMA sublayer, which are responsible for encoding and decoding data signals for transmission through a serializer/deserializer.
