PrismTech Announces General Availability of First COTS SCA 4.0 Compliant Middleware Solution for Software Defined Radios

Allows SDR developers to leverage the benefits of SCA 4.0 middleware within their current SCA implementations while minimizing migration path to fully supporting the standard in future projects

Boston, MA, USA – June 05, 2013 – PrismTech™, a global leader in standards-based, performance-critical middleware, today announced the General Availability (GA) of Spectra™ ORB v2.0 the first compliant implementation of the SCA 4.0 Full and Lightweight CORBA® Profiles.

SCA 4.0 is a major revision of the Software Defined Radio (SDR) Software Communications Architecture standard.  SCA 4.0 is more scalable, lightweight, and flexible than the current SCA 2.2.2 specification and is compatible with radio sizes ranging from small, single channel radios to prime-power, multi-channel sets.

The SCA 4.0 specification includes transfer mechanisms to provide standardized client / server operations.  SCA 4.0 Appendix E identifies the approved set of platform specific transport and technology mappings, transformations, and model representations used to achieve conformance with the SCA Platform Independent model (PIM) as defined in the main specification. SCA 4.0 Appendix E.1 defines the first set of compliant platform specific technologies that can be used by SDR developers.  These are specified in the form of three new CORBA profiles, specifically:

  • Full Profile which is targeted for applications hosted on GPPs
  • Lightweight Profile which is targeted towards environments with limited computing support such as a DSP
  • Ultra-Lightweight Profile which is intended for processing elements with even more limited computing support such as an FPGA

PrismTech’s Spectra Common Data Bus (CDB) is a fully integrated and optimized SDR middleware stack.  It is the first standards based, high performance, low footprint, fully interoperable, COTS SCA middleware solution that can be deployed across multiple processor types, including GPP, DSP and FPGA environments.  Spectra CDB includes the Spectra ORB C++ Edition (for GPP) and C ORB Edition (for GPP and DSP); and the Spectra IP Core ORB (ICO) for FPGA and ASIC implementations.

With the new GA release of the Spectra ORB, fully compliant support is now provided for the SCA 4.0 Full and Lightweight Profiles.  Spectra ICO already supports the SCA 4.0 Ultra-Lightweight Profile.

“PrismTech has already established a strong reputation in the market for supporting the SCA standard within our Spectra product suite,” said Andrew Foster, Spectra CDB Product Manager, PrismTech.  “SCA 4.0 is a major update to the standard and we are pleased that we are the first middleware vendor to be supporting it in our products.”
