Patent ID: 8170062

Claim:
An apparatus comprising: a fabric configured on a first semiconductor die to communicate with at least one agent on the first semiconductor die according to an on-chip protocol; and a packetization logic layer configured on the first semiconductor die and coupled to the fabric to receive command information from the fabric on a command link and data information from the fabric on a data link and to combine the command information and the data information into a packet for transmission from the first semiconductor die to a second semiconductor die coupled thereto via an in-package packetized link in a multiplexed manner in which the command information and the data information are sent in different clock periods, wherein the packetization logic layer includes a credit request generator to generate a credit packet responsive to credit signals received from the fabric, and is to enable the transmission from the first semiconductor die to the second semiconductor die if the second semiconductor die has a sufficient number of credits to receive the packet.
