  4. What is RapidIO? • Packet-based memory-mapped switched interconnect architecture for in-system communications • Also supports device-level messaging • Also supports cc-NUMA (Globally Shared Memory) • LVDS Parallel interface for processors • SerDes Serial interface for DSP, Serial Backplane applications • High reliability • Open Standard

  5. MEM MEM MEM MEMy DSP DSP DSP DSP DSP DSP DSP DSP DSP Common Networking Topology Serial RapidIO Data Path Fabric RapidIO Fabric Control Plane Host Card DSP Line Card RapidIO Fabric Host uP Traffic Aggregation RapidIO ASIC Data NPU Host uP Host uP Host uP Ethernet Physical Layer Interface Control Ethernet / IP ATM / SONET Infiniband / Fibrechannel TDM Voice Traffic

  6. Supported Application Classes • Processor Local Bus • Processor Clustering • Coherent and Non-Coherent • DSP Farm • Serial Backplane These applications are supported by the current specs

  7. Protocol Enhancements • Virtual Channels • Packet/Cell Encapsulation • Flow Control • Multicast • Relaxed Acknowledgement Rules Possible enhancements to RapidIO that are currently under consideration These enhancements are designed to make RapidIO more suitable as a data-plane technology for embedded systems

  8. Supporting Technologies/Standards • System Bringup APIs • Software APIs for booting and configuring systems • HIP Platform Specification • Hardware interoperability evaluation board • Error Management Specification • Hardware and Software specs for the handling of errors detected by RapidIO in a system

  9. Mechanical Standards • Mezzanine Card • Work going on the extend PMC card standard to support RapidIO • RapidIO on cPCI 2.x • Taskgroup working to produce standard for mapping of Serial RapidIO in CompactPCI 2.x chassis
