Sample text

The Boot ROM provides the power-on logic and initialization for the hardware. Once the Boot ROM has been loaded, an operating system is loaded. This provides the core Startup 25 set of services and functions to load and manage the core SCA software components for the system. Once the operating system is loaded, the system is ready to start loading components of the Core Framework. The first entity that needs to be loaded is the CORBA Name Service. The Name Service provides a ‘well known’ location for applications to look up available services and applications.

5 The SCA reduces the development of Non-Recurring Engineering (NRE) for system development Standardizing on a common software infrastructure reduces the effort required for future systems because a common set of control routines and implementations are developed. This can have a positive impact on the development cost and schedule. The key is to develop a standard infrastructure that is applied across a variety of systems that supports the SCA capabilities. This last item is central to how an organization approaches the development and use of the SCA.

All waveforms and common services execute in this aspect. • User – This aspect is the view through which the user interacts with the radio set. There are two basic modes of interaction within this aspect. g. g. setting the gain parameter for a specific waveform instance. The SCA can be viewed as one realization of the Software Infrastructure aspect with some parts within the Applications and Services aspect. It defines a logical infrastructure for management and abstraction of physical hardware components, a standard set of abstractions for software components that form the digital processing portion of a waveform implementation, general services available for use by the system, and a set of common interfaces for managing, deploying, and configuring waveform applications within the system.
