The community continues to be very active with several new members joining the community and many key task groups working to augment the RapidIO specification stack. Spring 2015 Update


As the spring season takes hold, this is proving to be a busy 2015 here at  The community continues to be very active with several new members joining the community and many key task groups working to augment the RapidIO specification stack. Here is a look back at the significant related events and news from the Winter and Spring of 2015.

Chaired by Barry Wood of IDT, the Technical Working Group consist of several Task Groups working on various specification development efforts that will be integrated into the specification stack.  Participation in these Task Groups is open to all active members.

ARM 64-bit Coherent Scale Out Task Group – Chaired by Sam Fuller, Freescale

The ARM 64-bit Coherent Scale Out over RapidIO Task Group is responsible for developing a specification for multi SoC / core coherent scale out of ARM 64-bit cores with the following functionality:

      • coherent scale out of a few 10s to 100s cores & 10s of sockets
      • ARM AMBA® protocol mapping to RapidIO protocols
      • AMBA 4 AXI4/ACE mapping to RapidIO protocols
      • AMBA 5 CHI mapping to RapidIO protocols
      • Migration path from AXI4/ACE to CHI and future ARM protocols
      • support for NPU / GPU/ DSP / FPGA heterogeneous systems
      • HW hooks and definition to support RDMA, MPI, secure boot, authentication, SDN, Open Flow, Open Data Plane, etc
      • Other functionality as necessary to for performance critical computing – support Data Center, HPC and Networking Infrastructure system development and deployment
Software Task Group – Chaired by Barry Wood, IDT

The RapidIO Software Task Group is responsible for developing open source interface definitions and APIs using the “C” language under the Linux operating system for the following functionality:

      • Linux Kernel enhancements for RapidIO fabrics and endpoints
        • “Raw Driver” interfaces which support all endpoints
        • Fault tolerance / hot swap support
        • Customizable / optional enumeration / fabric discovery
      • Data Path Library for high performance data transfers between RapidIO endpoints
        • RDMA, Sockets, and Channelized Messaging
        • Reference implementation uses “Raw driver”
        • User Mode Driver for maximum performance
      • Fabric Management Library and Command Line Interpreter for RapidIO fabrics and endpoint management
        • Uses “Raw Driver” interfaces
        • Portable across endpoints and operating systems
        • Command Line Interpreter for basic configurability
Verification Task Group – Chaired by Terry Omar, Praesum

The RapidIO Verification Task Group is responsible for enhancing the System Verilog Universal Verification Methodology (UVM) RapidIO Bus Functional Model (BFM) in accordance with the following requirements:

      • Define features to be added to the BFM
        • RapidIO Specification 3.1 extensions including the NGSIS Space Profile
        • ARM 64-bit coherency support
      • Define new licensing model for BFM
      • Define interfaces to support customization / integration with AXI BFMs
      • Develop baseline verification environment for FPGA and SoC developments
100G+ PHY Task Group – Chaired by Chris Shelsky, Nexus Technology

The 100G+ PHY Task Group charter is to develop higher performance PHY specifications for the RapidIO protocol with the following requirements:

      • Determine and define 25G per lane or greater PHY leveraging industry standard specification(s)
      • Evaluate and confirm PHY definition will improve or maintain existing PHY characteristics
        • Improve power efficiency
        • Maintain asymmetric link operation
        • Maintain low latency characteristics
        • Maintain fault tolerant characteristics
        • Maintain reliability characteristics assuming a bit error rate of less than 10^-12
      • Specify a low latency PHY suitable for dual and quad-socket cache coherency applications
      • Outline and prioritize additions/improvements to the PHY feature set
      • Other additions and improvements to the PHY feature set as requested Marketing Working Group – Chaired by Ravi Thummarukudy, Mobiveil

The Marketing Working Group manages the promotion of RapidIO unified fabrics and related products. The group meets regularly to plan for participation in various industry conferences and exhibitions.
