RapidIO.org releases revision 3.1 of the RapidIO Specification Stack

RapidIO Specification Updated with new High Availability and Fault Tolerant Extensions

Austin, Texas, 13 October 2014 – RapidIO.org announced today the release of the RapidIO 3.1 Specification bringing additional High Availability and Fault Tolerant extensions to the current RapidIO specification to address critical system performance needs of Military and Aerospace applications.

In June of 2012, the Next Generation Space Interconnect Standard (NGSIS) community selected RapidIO as the basis for the digital data transport and enhanced features to be defined for space applications.  Working together, the NGSIS community and RapidIO.org formed a “Part S” Task Group within the RapidIO.org Technical Working Group to develop a unique set of features for use in space applications.  The RapidIO 3.1 Specification release is a culmination of the “Part S” Task Group which included contributions from the following  RapidIO.org member companies: BAE Systems, Freescale, Honeywell, IDT, Mobiveil, Texas Instruments, Seakr Engineering, US Air Force Research Lab and Xilinx.

Key feature enhancements included in the RapidIO 3.1 Specification release include:

    • Structurally Asymmetric links
    • Degradation of 4x/2x/1x port to 2x operation on lanes 2 and 3
    • Require all of RapidIO Part 8 Error Management Extensionslogo
    • Multicast Extensions for dev8 and dev16 devices
    • Time to Live functionality in switches
    • Multicast Event Control Symbol Time Synchronization
    • Support for software assisted error recovery
    • Performance Diagnostics

The NGSIS standards are developed to provide sufficient flexibility to enable users to implement a variety of system configurations, while meeting goals for interoperability and robustness for space.

The presentation below provides an overview of the RapidIO 3.1 Specification release and the NGSIS initiative.
