Network on chip with partitions

A network on chip (‘NOC’), the NOC comprising:

• integrated processor (‘IP’) blocks, routers, memory communications controllers, and network interface controller, each IP block adapted for data communications to a router through a memory communications controller and a network interface controller, each memory communications controller controlling communication between an IP block and memory, and each network interface controller controlling inter-IP block communications through routers;
• the network organized into network partitions, each network partition including at least one IP block, each network partition assigned exclusive access to a separate physical memory address space, wherein the network organized into network partitions further comprises a partition of routers that are adjacent to one another within the network partition and routers on a boundary of the network partition, wherein the partition of routers that are adjacent to one another within the network partition are configured to exclude from entering the network partition messages originating outside the network partition that are addressed to network locations inside the network partition;
• and
• one or more applications executing on one or more of the network partitions.

A computer program product for data processing with a network on chip (‘NOC’), the NOC comprising integrated processor (‘IP’) blocks, routers, memory communications controllers, and network interface controller, each IP block adapted for data communications to a router through a memory communications controller and a network interface controller, each memory communications controller controlling communication between an IP block and memory, and each network interface controller controlling inter-IP block communications through routers, the computer program product disposed in a computer readable non-transmission medium, wherein the computer readable non-transmission medium is not a signal, the computer program product comprising computer program instructions capable of:

• organizing the network into network partitions, each network partition including at least one IP block, each network partition having its own physical memory address space, wherein organizing the network into network partitions further comprises configuring a partition of routers that are adjacent to one another within the network partition with routers on a boundary of the network partition to exclude from entering the network partition messages originating outside the network partition that are addressed to network locations inside the network partition;
• and
• executing one or more applications on one or more of the network partitions.
