Abstract: A method and an apparatus for retiming in a network of multiple context processing elements are provided. A programmable delay element is configured to programmably delay signals between a number of multiple context processing elements of an array without requiring a multiple context processing element to implement the delay. The output of a first multiple context processing element is coupled to a first multiplexer and to the input of a number of serially connected delay registers. The output of each of the serially connected delay registers is coupled to the input of a second multiplexer. The output of the second multiplexer is coupled to the input of the first multiplexer, and the output of the first multiplexer is coupled to a second multiple context processing element. The first and second multiplexers are provided with at least one set of data representative of at least one configuration memory context of a multiple context processing element.

Abstract: A method and an apparatus for position independent reconfiguration in a network of multiple context processing elements are provided. Wach multiple context processing element in a networked array of multiple context processing elements has an assigned physical identification. Virtual identifications may also be assigned to a number of the multiple context processing elements. Data is transmitted to at least one of the multiple context processing elements of the array, the data comprising control data, configuration data, an address mask, and a destination identification. The transmitted address mask is applied to either the physical or virtual identification and to a destination identification. The masked physical or virtual identification is compared to the masked destination identification.

Abstract: A method and apparatus for providing local control of processing elements in a network of multiple context processing element are provided. A multiple context processing element is configured to store a number of configuration memory contexts. This multiple context processing element maintains data of a current configuration. State information is received from at least one other multiple context processing element. At least one configuration control signal is generated in response to the state information and the data of a current configuration. One of multiple configuration memory contexts is selected in response to the configuration control signal, the selected configuration memory context controlling the multiple context processing element. Each multiple context processing element in the networked array of multiple context processing elements has an assigned physical and virtual identification.
