• [+]C Edition DSP

  PrismTech has achieved a major breakthrough by porting OpenFusion e*ORB SDR C Edition to a number of DSP platforms. The port has been made possible because of OpenFusion e*ORB C Edition’s unique modular micro-kernel architecture combined with the realization of other advanced design goals such as reduced code and data segment.

  OpenFusion e*ORB SDR C Edition for DSP is the first product that is small and fast enough to bring CORBA to the DSP world. Digital Signal Processing is a key technology fuelling innovative, high growth applications for many of today’s fast growing markets such as digital wireless, broadband access, digital audio, high-resolution imaging and digital motor control. DSP is unique because it processes data in real time making it perfect for applications that cannot tolerate any delays.

  The DSP remained until recently the last frontier for CORBA. However, modern applications demand extensive functionality combined with great flexibility in ever smaller devices and it is this that has driven the porting of CORBA to DSPs. Running CORBA on a DSP achieves flexibility and simplifies integration by exposing the services offered by the DSP far more widely than is possible with any other technology.

  Benefits of CORBA on a DSP

  Any application where a DSP is integrated with external systems of any kind will benefit from the simplified integration and enhanced flexibility provided by CORBA. The benefits of flexibility are very apparent in low-power hand-held devices such as mobile phones. Other applications that can benefit include:

  • Automobile Applications, including navigation systems
  • Avionics
  • Digital Radio
  • Industrial Controllers
  • IP Phones, IP Video Phones
  • Multi function printers
  • Smart Biometric Solutions
  • Software Defined Radio
  • Streaming Media Products, including personal video recorders, personal audio recorders
  • Surveillance Systems
  • VoIP, providing standards-based integration of host and DSP
  • All types of wireless applications

  Overall the cost of developing systems is reduced when CORBA is adopted. Without CORBA, a-priori design decisions are made that lock designers into costly design, implementation and test cycles as they struggle to rebalance task distribution to reduce power consumption. In a CORBA based system task allocation decisions can be made on the fly making it much easier and quicker to determine the optimum task allocation.

  Unrivalled Flexibility In many of today's signal processing systems, functionality is partitioned between the power-hungry General Purpose Processor (GPP) (frequently an ARM core) and the low power consuming DSP - the allocation of functionality is made at design time and cannot easily be changed later at runtime.

  However, when a DSP exposes its services through CORBA, it enables other devices, wherever they may be located, to call in and leverage that functionality. CORBA provides in essence a location transparency.

  This has a major impact on the design of systems - it is no longer necessary to statically locate tasks in either the DSP or the GPP, the tasks can be swapped from the GPP to the DSP and vice versa according to run time considerations. This enables designers to optimize systems in ways that are not possible with current technology. It also allows designers to consider the GPP and DSP as a single, homogenized platform and means that they can create multiple, flexible, configurable products on the same hardware platform. The result of this is shorter time to market for new product developments. In addition runtime re-configurability offers tremendous performance and power consumption advantages.

  Increased flexibility means smaller, cooler-running devices can be created. DSPs generally consume less power than GPPs and rebalancing the allocation of tasks between the GPP and DSP can result in an overall reduction in power consumption. Reduced power consumption means smaller batteries or extended battery life.

  The OpenFusion e*ORB SDR Advantage

  Even modern DSPs are extremely resource constrained devices and ORBs from other vendors are simply too large in terms of their resource requirements to fit effectively on a DSP. Only OpenFusion e*ORB SDR, with its configurable modular architecture has a footprint small enough to fit on a DSP.

• [+]Lightweight Naming

  Low Footprint, High Performance

  The OpenFusion e*ORB SDR Lightweight Naming Service provides a low footprint, high performance standards based object location facility for use in DRE (Distributed Real-time Embedded) systems. With a pure ANSI C language core and support for both C++ and C Language mappings, the product implementation is POSIX compatible ensuring easy portability to any target platform.

  The OpenFusion e*ORB SDR Lightweight Naming Service is a member of PrismTech’s growing family of Distributed and Wireless Software Infrastructure products. This fully OMG (Object Management Group) and SCA (Software Communications Architecture) compliant implementation provides the low footprint, high performance and open architecture required for use in real-time and embedded SDR environments.

  A distributed “white pages” object location facility targeted initially at the Software Radio domain but providing much wider applications in all areas of real-time embedded systems.

  This implementation is based on a highly optimized subset of the OMG Naming Service and provides a standards based mechanism by which a client can locate an object reference using a logical name associated with an object. The OpenFusion e*ORB SDR Lightweight Naming Service is a directory service for distributed objects.

  When to use the Lightweight Naming Service

  System resources, at the most basic level in object-based systems, are identified by an object reference, which will not bear any relationship to the type of the resource (e.g. a Domain Manager). The Naming Service allows useful, understandable names to be associated with resources, holding these in an easily navigable structure of related names and naming contexts. An application can therefore use the Naming Service to find a particular resource by a simple name, rather than via a complex object reference.

  The Naming Service provides an open, standardized naming repository which means that applications can discover objects without needing to know their physical location or underlying reference.

  The OpenFusion e*ORB SDR Lightweight Naming Service has also been tailored to conform to the requirements of the SCA, which specifies that Soft-radio management components such as the CF Domain Manager can obtain object references to other framework resources by looking them up by name using the Naming Service.

  In telecoms, each underlying network element in a large-scale system will typically have a unique name related to the element type and physical location. By registering (binding) these names into the Naming Service, network management applications can then later query the Naming Service to get the appropriate reference to interrogate, for example, a faulty switch.

  The product has a unique and highly optimized architecture which allows it to be used in extremely resource constrained environments such as mobile hand-held devices.

  The OpenFusion Advantage

• [+]Lightweight Event

  Low Footprint, High Performance

  The OpenFusion e*ORB SDR Lightweight Event Service provides a low footprint, high performance standards based asynchronous communications facility for use in DRE (Distributed Real-time Embedded) systems. With a pure ANSI C language core and support for both C++ and C Language mappings, the product implementation is POSIX compatible ensuring easy portability to any target platform.

  The OpenFusion e*ORB SDR Lightweight Event Service is a member of PrismTech’s growing family of Distributed and Wireless Software Infrastructure products. This fully OMG (Object Management Group) and SCA (Software Communications Architecture) compliant implementation provides the low footprint, high performance and open architecture required for use in real-time and embedded SDR environments.

  This implementation is based on a highly optimized subset of the OMG Event Service and provides a powerful asynchronous communications mechanism for embedded systems.

  When to use the Lightweight Event Service

  The OMG’s Event Service enables data, referred to as events, to be sent and received as messages between distributed software objects in a decoupled fashion. Objects which send messages through an intermediary, such as the Event Service, are referred to as being decoupled. Objects which send messages directly between each other are referred to as being tightly coupled.

  Decoupling objects which send messages to each other provides a variety of advantages and benefits over tightly coupling the objects. Advantages can include greatly improved scalability, improvements to maintainability, greater flexibility, and others. In general terms, decoupling enables events to be transmitted more efficiently and flexibly than when events are sent directly between objects (tightly coupled).

  The OpenFusion e*ORB SDR Lightweight Event service provides support for generic events and a highly efficient Push style event transfer where event communication is initiated by the supplier of events ‘pushing’ then out to consumers.

  The OpenFusion e*ORB SDR Lightweight Event Service also includes a number of important QoS extensions to control the performance and behaviour of the service.

  The product has a unique and highly optimized architecture which allows it to be used in extremely resource constrained environments such as mobile hand-held devices.

  The OpenFusion Advantage

• [+]Lightweight Log

  Low Footprint, High Performance

  The OpenFusion e*ORB SDR Lightweight Log Service provides a low footprint, high performance standards based logging facility for use in DRE (Distributed Real-time Embedded) systems. With a pure ANSI C language core and support for both C++ and C Language mappings, the product implementation is POSIX compatible ensuring easy portability to any target platform.

  The OpenFusion e*ORB SDR Lightweight Log Service is a member of PrismTech’s growing family of Distributed and Wireless Software Infrastructure products. This fully OMG (Object Management Group) and SCA (Software Communications Architecture) compliant implementation provides the low footprint, high performance and open architecture required for use in real-time and embedded SDR environments.

  This implementation is based on a highly optimized subset of the OMG Telecom Log Service and provides a standard mechanism for storing records produced by applications residing in a distributed environment. These records are persisted in a memory only storage area owned and managed by the OpenFusion e*ORB SDR Lightweight Log Service.

  When to use the Lightweight Log Service

  Software developers use logging while building software systems to generate low-level traces and messages that contain detailed information about program execution. This information is typically used for debugging applications under development. However in order to facilitate ongoing system maintenance, logging of this kind of information will continue as the software is deployed in order to be able to analyze possible failures.

  The OpenFusion e*ORB SDR Lightweight Log Service provides two basic functions: firstly it provides a facility for components that produce log information to store the data, and secondly it provides a mechanism by which data can be disseminated to any interested parties.

  The OpenFusion e*ORB SDR Lightweight Log Service provides a central logging facility, enabling the asynchronous collection of informational messages from any component connected to the service and the controlled read access to this information.

  The OpenFusion e*ORB SDR Lightweight Log service has been tailored to conform to the requirements of the SCA, which specifies that Soft-radio components that are log-producers must be able to generate standardized records. A log producer is a SCA compliant core framework component (e.g. DomainManger, Application, ApplicationFactory, DeviceManager, Device) or an application’s CORBA® capable component (e.g., Resource, ResourceFactory) as specified in the SCA specification.

  The OpenFusion Advantage
