Tsi721 - Block Diagram


RapidIO Bridge

The Tsi721 converts 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 at the same time using multiprocessor clusters that may only be PCIe enabled. Using the Tsi721, applications that require large amounts of data transferred efficiently without processor involvement can be executed using the full line rate block DMA+Messaging engines of the Tsi721.
