ABSTRACT:
A two domain network linking a first and second data processing system enables efficient data transfers between modules in the first system and modules in the second system through linkage by bus exchange modules having message queues and snoop-write address queues in each domain. Each system also allocates bus access using a selectively adjusting bus access priority arbitration logic unit. The Snoop-Write address queues in each bus exchange module can temporarily hold a sequence of Write OP addresses snooped from one domain for invalidation in another domain without requiring the bus exchange module to dominate its access priority over other requesting modules.
