摘要： Some embodiments provide a configurable IC that includes a configurable routing fabric with storage elements (1710, 1720). In some embodiments, the routing fabric provides a communication pathway that routes signals to and from source and destination components. The routing fabric of some embodiments provides the ability to selectively store the signals passing through the routing fabric within the storage elements (1710, 1720) of the routing fabric In this manner, a source or destination component continually performs operations (e g, computational or routing) irrespective of whether a previous signal from or to such a component is stored within the routing fabric. The source and destination components include configurable logic circuits, configurable interconnect circuits, and various other circuits that receive or distribute signals throughout the configurable IC.

摘要： An integrated circuit ('IC') that includes a configurable routing fabric with controllable storage elements is described. The routing fabric provides a communication pathway that routes signals to and from source and destination components. The routing fabric may provide the ability to selectively store the signals passing through the routing fabric within the storage elements of the routing fabric. In this manner, a source or destination component may continually perform operations (e.g., computational or routing) irrespective of whether a previous signal from or to such a component is stored within the routing fabric. The source and destination components include configurable logic circuits, configurable interconnect circuits, and various other circuits that receive or distribute signals throughout the IC.

摘要： 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 first 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.

摘要： Some embodiments provide an IC with configuration context switchers. The IC includes several configurable circuits, each of which configurably performs one of several operations at any given time, based on the configuration data set that it receives at that time. The IC includes several storage circuits for storing several configuration data sets for each of the configurable circuits. The IC also includes a context switching interconnect circuit for switchably connecting the configurable circuit to different sets of storage circuits to receive different sets of configuration data sets. The context switcher includes one or more stages for re-timing the data coming from the configuration storage elements. The stages can include interconnect circuitry or storage circuitry. Some embodiments build one of the stages in the configuration data storage elements. Some embodiments encode the configuration data bits and hence utilize a decoder in the context switcher to decode the encoded configuration data.
