| 20110267103 | METHOD AND APPARATUS FOR SAVING POWER IN AN INTEGRATED CIRCUIT - Some embodiments provide an integrated circuit (‘IC’) that includes at least first and second circuits operating at a first voltage. The IC includes, between the first and second circuits, a direct connection comprising a third circuit for transmitting a signal from the first circuit to the second circuit at a second voltage that is lower than the first voltage. At least one of the first and second circuits is a configurable circuit for configurably performing operations. | 11-03-2011 |
| 20110089970 | CONFIGURATION CONTEXT SWITCHER - 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. | 04-21-2011 |
