Overview

Features Not Supported:

∙Compliance with the Global Shared Memory specification (GSM)

∙8/16 LP-LVDS compatible

∙Destination support of RapidIO Atomic Operations

∙Simultaneous mixing of frequencies between 1X ports (all ports must be the same frequency)

∙Target atomic operations (including increment, decrement, test-and-swap, set, and clear) for internal L2 memory and registers

1.3Standards

The SRIO peripheral is compliant to V1.2 of the RapidIO Interconnect Specification and V1.2 of the LP-Serial specification.

1.4External Devices Requirements

SRIO provides a seamless interface to all devices which are compliant to V1.2 of the LP-Serial RapidIO specification. This includes ASIC, microprocessor, DSP, and switch fabric devices from multiple vendors. Compliance to the specification can be verified with bus-functional models available through the RapidIO Trade Association, as well as test suites currently available for licensing.
