1. A device comprising:

  • a first streaming functional unit, wherein the first streaming functional unit is specialized circuitry configured to perform a first particular function;

    a first multiplexer operatively coupled between the first streaming functional unit and a first plurality of potential input sources;

    wherein the first multiplexer is dynamically configurable to pass streaming input from a selected one of the first plurality of potential input sources to the first streaming functional unit;

    a second streaming functional unit, wherein the second streaming functional unit is specialized circuitry configured to perform a second particular function;

    a second multiplexer operatively coupled between the second streaming functional unit and a second plurality of potential input sources;

    wherein the second multiplexer is dynamically configurable to pass streaming input from a selected one of the second plurality of potential input sources to the second streaming functional unit;

    wherein output of the first streaming functional unit is one potential input source, of the second plurality of potential input sources;

    a scheduler configured to;

    receive data indicating an execution plan to be processed;

    determine how to configure the first multiplexer and second multiplexer to make use of the first streaming functional unit and the second streaming functional unit in processing the execution plan; and

    send signals to dynamically configure the first multiplexer and second multiplexer to make use of the first streaming functional unit and the second streaming functional unit in processing the execution plan.
