Description:

Serial RapidIO

Offers Increased Bandwidth for HD Video and Telecom Infrastructure Systems

The TMS320C6455 DSP's integrated Serial RapidIO(SRIO) bus decreases overall system cost by reducing the need for additional devices used for switching and processor aggregation. Supported by an industry association of leading device, system and software manufacturers, the SRIO interconnect enables high-speed, packet-switched peer-to-peer connectivity. SRIO thus makes it much easier to implement multi-processing, providing a performance breakthrough for multi-channel implementations on multiple processors.

For video infrastructure applications, a 1x SRIO link is fast enough to send high-definition (HD) 1080i raw video between devices and a 4x SRIO link can easily send HD 1080p raw video between devices with room to spare. The use of SRIO in infrastructure applications with large "DSP farms" will allow the reduction of system cost (device count, board size and/or device cost) for OEM customers.)

Serial RapidIO Enables Scalable DSP-Based Systems with Flexible Topologies

Reduce System Cost with Serial Rapid IO

These are the many ways video infrastructure, telecom infrastructure and medical/imaging customers can reduce system cost by arranging scalable systems with Serial Rapid IO (SRIO).

SRIO is very flexible - it can be arranged in a ring and mesh topologies. Or, multiple C6455 DSPs can be connected through a switch, with or without local connections to one another and to ASICs and FPGAs. You can also connect multiple C6455 DSPs in a star topology, where five DSPs are all connected to one another. The use of Serial RapidIO in applications with large "DSP farms" will allow the reduction of system cost for OEM customers.
