UNIFIED SYSTEMS AND METHODS FOR INTERCHIP AND INTRACHIP NODE COMMUNICATION

摘要

Unified systems and methods for interchip and intrachip node communication are disclosed. In one aspect, a single unified low-speed bus is provided that connects each of the chips within a computing device. The chips couple to the bus through a physical layer interface and associated gateway. The gateway includes memory that stores a status table summarizing statuses for every node in the interface fabric. As nodes experience state changes, the nodes provide updates to associated local gateways. The local gateways then message, using a scout message, remote gateways with information relating to the state changes. When a first node is preparing a signal to a second node, the first node checks the status table at the associated local gateway to determine a current status for the second node. Based on the status of the second node, the first node may send the message or take other appropriate action.

主权项

1. A method for populating a status table for network nodes within a computing device, the method comprising:
activating a first integrated circuit (IC) coupled to a bus; registering first nodes associated with the first IC with a first gateway; populating a first status table at the first gateway with information about the first nodes associated with the first IC; and permitting intrachip communication between the first nodes associated with the first IC based on availability as indicated in the first status table.
