| RapidIO Specification 1.3 Part 1: I/O System Logical Layer |
Defines a rich variety of transaction types, such as DMA-style read and writes, that allow efficient I/O systems to be built. ANSI INCITS 413-2007 ISO/IEC 18372-2004 version 1 | 06/2005 | |
| RapidIO Specification 1.3 Part 2: Message Passing Logical Layer |
Defines the message passing or software-based coherency functions that enable support for distributed I/O and processing requirements. | 06/2005 | |
| RapidIO Specification 1.3 Part 3: Common Transport |
Specifies the header information added to a RapidIO logical packet and the way the header information is interpreted by a switching fabric. The RapidIO standard defines this mechanism independent of a physical implementation. | 06/2005 | |
| RapidIO Specification 1.3 Part 4: Parallel Physical Layer |
Defines an 8-bit and 16-bit parallel (8/16 LP-LVDS), point-to-point interface. | 06/2005 | |
| RapidIO Specification 1.3 Part 5: Global Shared Logical Layer |
Describes the standard approach for providing directory based coherent memory in a RapidIO-based multiprocessor system. Note: support for this feature is optional in RapidIO devices. | 06/2005 | |
| RapidIO Specification 1.3 Part 6: Serial Physical Layer Specification |
Includes physical layer header, 8B/10B coding, symbol generation, buffer management, lane striping and driver and receiver characteristics. | 06/2005 | |
| RapidIO Specification 1.3 Part 7: Interoperability Specification |
Defines interoperability requirements for RapidIO devices and also for RapidIO to PCI devices. | 06/2005 | |
| RapidIO Specification 1.3 Part 8: Error Management Extensions |
Describes the optional error management extensions, including additional register definitions for collecting device state. Also describes standard maintenance transactions for reporting error conditions to host devices. | 06/2005 | |
| RapidIO Specification 1.3 Part 9: Flow Control Extensions |
Describes optional extensions that provide XON/XOFF support to provide traffic management capabilities to manage congestion in more complex systems. | 06/2005 | |
| RapidIO Specification 1.3 Part 10: Data Streaming Logical Layer, Phase I |
Defines a method for protocol independent encapsulation of payloads up to 64K bytes. | 06/2005 | |
| RapidIO Specification 1.3 Part 11: Multicast Extensions |
Defines a method for switch-based multicast of packets in a RapidIO network. | 06/2005 | |
| RapidIO Specification 1.3 Annex 1: Software/System Bring Up Specification |
Builds on the Interoperability Specification to define a standard set of software API functions for use in system bring up. | 06/2005 |
