Abstract

The present invention presents an efficient way to implement global ordering between a system interconnect and internal core interfaces in a MCMP system. In particular, snooping transactions on the system interconnect, processor requests, and processor request completions may trigger corresponding snooping transactions and request completions to the cores. The order in which the transactions are observed on the system interconnect may impose the order in which the transaction triggered to the core are generated. Since this ordering is between multiple interfaces this is referred to as global ordering.
