Mercury Computer Systems Announces RACE++ Dual-Channel Fiber-Optic Interface for Sensor I/O

8/16/2002 - Mercury Computer Systems has begun shipments of next-generation RINOJ Series fiber-optic interface cards based on the serial Front Panel Data Port (FPDP) specification for its RACE++® systems. The new RINOJ-F-2.5 Dual-Channel Fibre-Optic I/O daughtercard includes two fiber-optic interfaces, each running at 2.5 Gbaud, and each connected directly to its own RACE++ switch fabric interface.

The new high-performance I/O interface is specifically designed for streaming data applications where low latency and point-to-point speed are paramount. Each of the two independent channels has an input or output bandwidth capacity of 247 megabytes per second for a total bandwidth capacity of 494 megabytes per second per daughtercard. This represents nearly five times the bandwidth previously available in the same physical space.

The new Mercury RINOJ-F-2.5 I/O interface incorporates a sophisticated direct memory access (DMA) engine, which simplifies the task of designing data distribution algorithms for multi-computer architectures. The DMA engine has the ability to direct incoming data packets to the appropriate processors on a RACE++ switch fabric based on the contents of the data packet. This data-directed distribution feature frees the processors from input data flow housekeeping, which in turn enables the processors to achieve the fastest possible computational throughput.

The new design is entirely backward compatible with Mercury’s previous RINOJ-F interfaces, providing customers with a performance boost while maintaining full software compatibility.
