IOR-280 Mercury Computer Systems Rear Transition Module

The Mercury Computer Systems IOM-200 XMC and IOR-280 RTM Modules provide the industry's leading 10Gbps Ethernet IO density. When two IOM-200s are configured with the IOR-280 Rear Transition Module (RTM), up to eight channels of 10Gbps Ethernet can be supported per 6U OpenVPX slot. The IOM-200 module also includes a high-performance Altera Stratix IV GX field programmable gate array (FPGA) all in a single-wide XMC form factor. Because many algorithms can run up to 100 times faster on an FPGA than a CPU processor, developers can partition applications across FPGAs and CPU processors for maximum performance. The FPGA has 1,288 18x18 multipliers (using GX230HF) and a large supply of memory internally to assist with math intensive algorithms.

The IOM-200 is also designed around an open architecture using open standards such as the Vita 42 XMC form factor. The IOR-280 implements Vita 46 OpenVPX to enable high-speed connectivity with other 6U Open modules, such as Mercury's VPX SBC6521 single board computer and LDS6520 low-density server module. With this balance of a high-density 10Gbps Ethernet IO and a high-performance FPGA, the IOM-200 is extremely well suited to act as an external connection for a signal processing subsystem. It handles both real-time IO requests and digital signal processing such as a math co-processor for fixed-point operations used in digital image processing. In addition to 10Gbps Ethernet, the Stratix IV's flexible gigabit transceiver blocks allow other high-speed interface protocols to be implemented.
