  • Method and system for resolution of transaction collisions to achieve global coherence in a distributed symmetric multiprocessor system
    Patent number: 6591348
    Abstract: A distributed system structure for a large-way, symmetric multiprocessor system using a bus-based cache-coherence protocol is provided. The distributed system structure contains an address switch, multiple memory subsystems, and multiple master devices, either processors, I/O agents, or coherent memory adapters, organized into a set of nodes supported by a node controller. The node controller receives commands from a master device, communicates with a master device as another master device or as a slave device, and queues commands received from a master device. The node controller has a deterministic delay between latching a snooped command broadcast by the address switch and presenting the command to the master devices on the node controller's master device buses.
