REDHAWK Manual - 2.2.0

REDHAWK is a software framework designed to support the design, development, deployment, management, upgrade, and recycling of real-time distributed applications as well as the systems that run them.

To support the design and development of software applications, REDHAWK provides tools that allow development and testing of software modules, or “components”. In addition, REDHAWK provides tools to facilitate composure of components into “waveforms” that can be seamlessly deployed as “applications” on a single host computer or a network-enabled system of computers.

Deployment, management, and upgrade of real-time distributed applications is supported by providing a runtime environment.

The runtime environment can:

Finally, REDHAWK supports the recycling of applications by establishing strong boundaries between processing stages and providing an integration path for existing libraries into the REDHAWK infrastructure.

Benefits of Using REDHAWK

REDHAWK provides the following benefits when used in a computing system:

What Systems May Benefit from Using REDHAWK?

A hardware/software system may benefit from the use of REDHAWK if it:

Relationship to the SCA

REDHAWK adopts a significant number of concepts from the SCA (specifically, version 2.2.2). As a result, the SCA specification is a very useful piece of supplemental reading to the REDHAWK documentation.

Overview of this Document

REDHAWK is infrastructure that enables for the distribution of processing elements over an arbitrary number of computers connected to a network. These processing elements can be associated with different types of hardware (i.e.: data acquisition) to ingest/egress data, or to leverage some specialized coprocessors. The REDHAWK framework provides tooling for the creation, deployment, and management of these processing elements and hardware interaction elements.

The basic processing element in REDHAWK is a component, which is described in detail in Components and Component Structure. A component is a single linux process. Components interact with each other through connections, which are described in Connections. An application, described in Waveforms, is a logical association of interconnected components.

Hardware interaction elements are called devices. Devices are described in Working with Devices. Devices can be logically associated together in nodes, which are described in Nodes. A specialized device called GPP is used to model the processing availability of a single computer. Each node contains no more than one GPP, and is generally mapped to a single computer. By deploying components through different GPP devices, an application can be automatically distributed over multiple computers. The distributed processing aspects of REDHAWK are discussed in Distributed Computing and RF Devices.

Components can either be deployed through a distributed environment called a domain, as seen in The Runtime Environment, or standalone through a Sandbox.

REDHAWK contains code generators and visualization tools. Descriptions of this tooling are available throughout this document.
