1. A device comprising:

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

    wherein the first streaming function unit is dynamically configurable to perform any one of a first plurality of functions;

    wherein the first plurality of functions includes a first function;

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

    wherein the second streaming function unit is dynamically configurable to perform any one of a second plurality of functions;

    wherein the second plurality of functions includes a second function;

    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 perform the following in response to a request to perform an operation that involves the first function and the second function;

    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 performing the operation;

    send one or more first signals to the first streaming functional unit to dynamically configure the first streaming functional unit to perform the first function;

    send one or more second signals to the second streaming functional unit to dynamically configure the second streaming functional unit to perform the second function; and

    send signals to the first multiplexer and the second multiplexer 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 performing the operation.
