Serial RapidIO to PCI Bridge Reference Design
from Jennic Ltd
The use of this design is governed by, and subject to, the terms and conditions of the Altera Hardware Reference Design License Agreement.
Overview
The Serial RapidIO® to PCI Bridge provides the capability to bridge between a Serial RapidIO interface and a PCI interface. It is part of a family of devices that are intended for applications which are currently based on legacy interface standards, such as PCI, but need to use a switched serial interconnect, such as Serial RapidIO.
The Serial RapidIO to PCI Bridge transparently converts PCI memory read and write transfers into RapidIO I/O or maintenance transactions. It appears as eight PCI windows, each of which can be mapped to different RapidIO destinations. Received RapidIO I/O transactions are converted to PCI memory accesses using an integrated DMA controller.
The bridge utilizes Jennic's RapidIO and PCI Interface intellectual property (IP) cores and the semiconductor vendor's on-chip SERDES/transceivers. Jennic's RapidIO IP core product line provides a range of complete, fully integrated RapidIO interface solutions to address a wide range of applications including endpoints and switches. These are based around a common, modular architecture and implement the physical, transport, and logical layer RapidIO standards and are suitable for implementation in a range of Altera® technologies including devices from the Stratix®, Stratix GX and HardCopy® product families.
