Abstract
Various methods and apparatus are described for communicating transactions between one or more initiator IP cores and one or more target IP cores coupled to an interconnect. A centralized Memory Management logic Unit (MMU) is located in the interconnect for virtualization and sharing of integrated circuit resources including target cores between the one or more initiator IP cores. A master translation look aside buffer (TLB) stores virtualization and sharing information in the entries of the master TLB. A set of two or more translation look aside buffers (TLBs) locally store virtualization and sharing information replicated from the master TLB. Logic in the MMU or other software updates the virtualization and sharing information replicated from the master TLB in the entries of one or more of the set of local TLBs.
