Configurable IC Having a Routing Fabric with Storage Elements

摘要

Some embodiments provide a configurable IC that includes a configurable routing fabric with storage elements. 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 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.

1. A method comprising:
storing a first signal along a particular path of a routing fabric that directly connects a first circuit of an integrated circuit (“IC”) to a second circuit of the IC; and while storing said first signal along the particular path, passing a second signal from the first circuit to the second circuit along the particular path.
