Components

A component is a modular building block that can be inserted into any number of signal processing applications to perform a specific and reusable function. A component is fully defined by its interfaces, properties, and functionality. Examples include a component that tunes, filters, and decimates a wideband signal and one that performs a FM demodulation. Some components inevitably need to be custom implementations, but a majority of signal processing functions can be reused and shared.

REDHAWK allows for developers to create components in either C++, Python, or Java. C++ is recommended for most computationally-intensive tasks, whereas Python or Java work well for handling metadata manipulation or command and control tasks.

Components can be interconnected together within a waveform to create a complete signal processing application or can be run independently in the REDHAWK Sandbox to perform trivial tasks on a local host. The figure below depicts the composition of components into a waveform.

REDHAWK Workflow

By using the REDHAWK Framework, basic processing elements may be encapsulated as components and reused by other REDHAWK compliant systems. Using the REDHAWK IDE and the included code generators, much of the code for control and input/output can be auto-generated. The figure below depicts the encapsulation of an arbitrary processing algorithm into an auto-generated REDHAWK component wrapper.
