I/O Expansion Devices Support Multicast Functionality

Wed, 01/14/2009 - 11:29am


IDT® (Integrated Device Technology, Inc.) introduces two PCI Express® (PCIe®) Gen2 switching solutions. Optimized for computing and embedded applications, the new solutions are based on proven, IDT switching architecture and technology, and support multicast functionality for increased system resource utilization. The solutions - a 32-lane, 8-port and a 48-lane, 12-port - also include advanced features to minimize power consumption, maximize performance-per-watt, and reduce total cost of ownership and thermal design complexity. Both devices support PCIe multicast functionality, which allows any switch port to simultaneously send identical data to two or more switch ports, increasing system resource utilization by decreasing the previously required hardware and software overhead needed to send copies of data in a looped manner. This extension of the PCIe standard ensures consistency in data and table information among multiple system elements and extends the reach of PCIe into emerging enterprise computing and embedded applications requiring robust data coherency and sharing.,
