RapidIO.org Recent News

RapidIO.org Technical Working Group – Chaired by Barry Wood, IDT

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

RapidIO.org Marketing Working Group – Chaired by Ravi Thummarukudy, Mobiveil

The RapidIO.org 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.
