1.1

Overview

IDT is the leading supplier of RapidIO® and PCI Express Interconnect solutions, providing a broad portfolio of switches,

bridges, IP, and development platforms for defense aerospace, video, imaging, and wireless markets. The Tsi721 is IDT's

solution for hardware-based PCIe Gen2 to RapidIO Gen2 protocol conversion in a bridging device.

The Tsi721 converts transactions from PCIe to RapidIO, and vice versa, and provides full line rate bridging at 20 Gbaud. Using

the Tsi721, designers can develop heterogeneous systems that leverage the peer-to-peer networking performance of RapidIO

while using multiprocessor clusters that may be only PCIe enabled. In addition, applications that require large amounts of data

transferred efficiently without processor involvement can be executed using the full line rate of the Tsi721’s Block DMA Engine

and Messaging Engine.

Key to the Tsi721 is the hardware bridging functionality that converts PCIe transactions to RapidIO, and vice versa. The Tsi721

supports PCIe non-transparent bridging for transaction mapping. The device has both RapidIO and PCIe endpoints embedded

in the bridge, and each of its Block DMA/Messaging DMA channels can buffer up to 8 KB of data on the PCIe side.
