Object-oriented component and framework architecture for signal processing
View Patent ↗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.
1. A method for reducing the equipment payload for signal intelligence equipment in a signal intelligence bay comprising the step of:
providing a signal intelligence system as the signal intelligence equipment payload in a signal intelligence bay, the signal intelligence system using a runtime reconfigurable software receiver including multiple software components which, when programmed, function as a signal intelligence system having a receiver interface, a signal energy detection system, a system for signal recognition, a direction finding system or a countermeasure system such that the reconfigurable software receiver is capable of providing a predetermined signal intelligence function,
each software component run on a multi-distributed processor system having a number of distributed interconnected processors each connected to a processor manager that displays and controls components, maintains status and interacts with a framework manger, the framework manager controlling the interconnected processors to effectuate the predetermined signal intelligence function, each software component with the associated processor executing the software of the component as instantiated by the processor manager, the software components inheriting characteristics from component base classes to ensure interface compatibility,
the framework manager having an installed a plan corresponding to the predetermined signal intelligence function and operating on an intercepted signal,
the framework manager instructing each processor manager to access from a list of software components the software components necessary to carry out the plan and to initialize the system at runtime based on the properties of the accessed software components such that the software receiver is configurable at runtime in accordance with the predetermined signal intelligence system function, whereby the signal intelligence system plan is implemented to configure the signal intelligence system at runtime to carry out the signal intelligence function defined by the plan, such that multiple signal intelligence functions can be provided by a software-reconfigurable receiver without having to provide separate signal intelligence modules, one for each signal intelligence function.
2. The method of claim 1 , wherein the signal processed by said signal intelligence system includes streaming data.
3. The method of claim 1 , and further including a data fabric for data communications between a processor and a software component. signal intelligence system includes streaming data.
4. The method of claim 3 , wherein the data fabric includes one of a switched interconnect or a network.
5. The method of claim 3 , wherein the data fabric includes a database.
6. The method of claim 1 wherein the basic operational capability of the software component is inherited from a component base class, whereby the software component can take advantage of previously developed software in the component base class.
7. The method of claim 1 , wherein the plan includes a list of the components, what processor the components are located on, and how the components and processor are interconnected.
8. The method of claim 7 , wherein the plan includes initial parameter values.
9. The method of claim 1 , and further including providing a data fabric having a platform-independent layered structure for connecting components and processors in a platform-independent manner.
10. The method of claim 1 , wherein components communicate with other components only through framework-provided services.
