US Patent 12111783 Flexible on-die fabric interface

An interface for coupling an agent to a fabric supports a set of coherent interconnect protocols and includes a global channel to communicate control signals to support the interface, a request channel to communicate messages associated with requests to other agents on the fabric, a response channel to communicate responses to other agents on the fabric, and a data channel to couple to communicate messages associated with data transfers to other agents on the fabric, where the data transfers include payload data.
