Abstract
A computer system is disclosed having a requesting bus agent that issues a communication transaction over a bus and an addressed bus agent that defers the communication transaction to avoid high bus latency. The addressed bus agent later issues a deferred reply transaction over the bus to complete the communication transaction. Special snoop ownership and cache state transition rules maintain cache coherency and processor consistency during deferred communication transactions.
