Method and system for transmitting address commands in a multiprocessor system

摘要

A method and system for transmitting address commands in a multiprocessor system comprising multiple nodes interconnected by an address bus. A request for arbitration of an address bus is transmitted from a controller within a node of multiple nodes to an arbitration switch, which controls transmission across the address bus. The address command is transmitted from the controller to the arbitration switch, in response to receiving a grant of arbitration of the address bus. The address command is then broadcast from the arbitration switch to a controller within each node of multiple nodes, in response to receiving the address command at the arbitration switch. The address command is broadcast from the controller within each node, in response to receiving the broadcast address command at the controller within each node, such that all address command transmissions on the address bus are transmitted to each processor within a multiprocessor system.
