CONFIGURABLE IC WITH PACKET SWITCH CONFIGURATION NETWORK

Some embodiments of the invention provide configurable integrated circuit (IC) that includes several configurable circuits that are conceptually in tiles. The IC also includes a first data network for passing data between the configurable circuits. The IC further includes a second packet-switch network for receiving packets of data from the outside of the configurable IC and switchably routing each packet to at least one destination tile. In some embodiments, the second packet-switch network supplies data from the tiles that the configurable circuits output in response to data packets received from outside of the configurable IC. Also, in some embodiments, a particular packet that is for a particular resource in a particular tile includes a fist address that identifies the particular configurable tile from the plurality of configurable tiles, and then a second address that identifies the particular resource within the particular configurable tile.
