Abstract: A reconfigurable distributed signal processing system uses an object-oriented component-framework architecture in which the system permits large-scale software reuse. This is accomplished by the use of a framework and a number of reusable, reconfigurable software components that are hardware independent. The components communicate over a data fabric using open published APIs over one or more data communications mechanisms. Interchangeable software components are used that perform the signal processing. Interchangeability is assured by each component meeting a required interface in which the component inherits the required interface elements from component base classes. This use of inheritance to assure interface compliance also reduces the programming work required for developing a component. Most importantly, the interchangeable components are reconfigurable into various systems at runtime, as defined by a Plan.
