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： A system and method for reducing power consumption in a reconfigurable integrated circuit. Some embodiments provide placement and routing programs that reduce the number of bits to be reconfigured. Some embodiments provide placement and routing programs that increase the number of groups of circuits that do not need reconfiguration at some times. Some embodiments include circuits that selectively block reconfiguration.

摘要： Some embodiments provide a method that outputs from a configurable IC a first set of data bits from a trace buffer. Each bit of the first set of data bits is simultaneously generated in the configurable circuits and, in some embodiments, multiple data bits of the first set of data bits do not reach the trace buffer simultaneously. The method also determines a set of relative delays for the first set of data bits and arranges the first set of data bits into a second set of data bits by compensating for the relative delays.

摘要： A novel method for designing an integrated circuit ("IC") by rescaling an original set of circuits in a design of the IC is disclosed. The original set of circuits to be rescaled includes sequential nodes, combinational nodes, and interconnects. Each sequential node is associated with a phase of a clock. The method generates a rescaled set of circuits that includes multiple replica sets of the circuits. Each replica set of circuits includes sequential nodes, combinational nodes, and interconnects that are identical to nodes and interconnects in the original set of circuits. Each sequential node is associated with a phase of a clock that is at a fraction of the phase of its corresponding sequential element in the original set. The method connects nodes in each replica set of circuits to a logically equivalent node in another replica set. The method replaces the original set of circuits with the rescaled set of circuits.
