An island-based network flow processor (IB-NFP) integrated circuit includes islands organized in rows. A configurable mesh control bus extends through the islands. The configurable mesh control bus is configurable to have a unidirectional tree structure such that configuration information passes into the integrated circuit, through a root island, through the branches of the tree structure, and to each of the other islands. The functional circuits of the islands, as well as a configurable mesh data bus of the integrated circuit, are all configured with configuration information supplied via the tree structure. In one example, the configurable control mesh bus portion of each island includes a statically configured switch and multiple half links that radiate from the switch. The static configuration is determined by hardwired tie off connections associated with the island.
