A network on chip (‘NOC’) that includes integrated processor (‘IP’) blocks, routers, memory communications controllers, and network interface controllers, with each IP block adapted to a router through a memory communications controller and a network interface controller, where each memory communications controller controlling communications between an IP block and memory, and each network interface controller controlling inter-IP block communications through routers, the NOC also including a computer software application segmented into stages, each stage comprising a flexibly configurable module of computer program instructions identified by a stage ID with each stage executing on a thread of execution on an IP block.
