    摘要: A reconfigurable integrated circuit (“IC”) that has several reconfigurable circuits, each having several configurations for several configuration cycles. The reconfigurable circuits include several time-extending reconfigurable circuits. During the operation of the IC, each particular time-extending reconfigurable circuit maintains at least one of its configurations over at least two contiguous cycles, in order to allow a signal to propagate through a signal path, which contains the particular time-extending circuit, within a desired amount of time.

    摘要: Some embodiments provide a reconfigurable integrated circuit (“IC”). This IC has several reconfigurable circuits, each having several configurations for several configuration cycles. The reconfigurable circuits include several time-extending reconfigurable circuits. During the operation of the IC, each particular time-extending reconfigurable circuit maintains at least one of its configurations over at least two contiguous cycles, in order to allow a signal to propagate through a signal path, which contains the particular time-extending circuit, within a desired amount of time. Some embodiments provide a method of designing a reconfigurable IC that has several reconfigurable circuits, each having several configurations and operating in several reconfiguration cycles. The method identifies a signal path through the IC that does not meet a timing constraint. The signal path includes several circuits, one of which is a particular reconfigurable circuit. The method then maintains a configuration of the particular reconfigurable circuit constant over at least two contiguous reconfiguration cycles in order to reduce signal delay through the signal path and thereby satisfy the timing constraint.

    摘要: Some embodiments provide an integrated circuit (IC) that has a first interface rate for exchanging signals in at least one direction with a circuit outside of the IC. The IC has multiple reconfigurable circuits. Each of the reconfigurable circuits is for reconfiguring at a second rate. The second rate is faster than the first interface rate. Each of the reconfigurable circuits reconfigures when configuration data that specifies an operation of the particular reconfigurable circuit changes from a first configuration data set that is stored in the IC to a second configuration data set that is also stored in the IC.

    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.
