ABSTRACT:
A network on chip (‘NOC’) comprising integrated processor (‘IP’) blocks, routers, memory communications controllers, and network interface controller, each IP block coupled to a router through a memory communications controller and a network interface controller, the NOC also including a port on a router of the network through which is received an invalidate command, the invalidate command including an identification of a cache line, the invalidate command representing an instruction to invalidate the cache line, the router configured to send the invalidate command to an IP block served by the router; the router further configured to send the invalidate command horizontally and vertically to neighboring routers if the port is a vertical port; and the router further configured to send the invalidate command only horizontally to neighboring routers if the port is a horizontal port.
