BILLERICA, Massachusetts, June 28, 2007 - CSP Inc. (NASDAQ: CSPI) MultiComputer Division, the leading supplier of rugged embedded clusters, announced the 3000 SERIES VXS-M16 Switch Module for its FastCluster Hybrid Computing platform on VXS (VITA-41). It implements Myricom’s 10-Gigabit clustering technologies and a serial crosspoint switch to support Freescale 8641D and Xilinx Virtex-5 Hybrid Compute nodes. FastCluster systems are targeted at high performance digital signal processing (DSP), SIGINT, radar and sonar applications in airborne, shipboard and UAV platforms where space, power and cooling are at a premium and interoperability is critical.

The VXS-M16 switch module provides 20 GBytes/sec of bi-section bandwidth across seven (7) 3000 SERIES VXS payload blades and two (2) front panel I/O ports (copper or fiber) on the switch module. It implements a VXS collapsed dual-star topology.

The VXS-M16 switch module implements a monolithic, low power Myri-10G 16 port switch from Myricom. The Myri-10G switch leverages the XAUI Physical-layer de facto standard for 10-Gigabit/sec data rate communication. Each Myri-10G XAUI port (4 serial, 8b/10b-encoded links each way) delivers 12.5 Gbaud signaling rate (4 x 3.125) and 10 Gigabit/sec data rate. The Myri-10G switch fabric implements byte-level flow control, source-based routing and cut-through switching.

A "protocol agnostic" serial crosspoint switch on the VXS-M16 is used to redirect serial links on the backplane. Up to twenty (20) serial point-to-point links (1-lane ea.) across four VXS payloads slots and 5 ports of the Myri-10G switch are easily configured to adapt to the dataflow requirements, providing direct point-to-point FPGA serial links between payloads. Furthermore, the serial crosspoint switch supports multi-cast operations increasing the streaming capability of the FPGA serial connectivity.

In addition, the VXS-M16 supports a Control Plane (Ethernet) and Management Plane (I2C). The Control and Management functions are performed by a control processor on the switch board, enabling the static configuration of the crosspoint switch and the monitoring of the Myri-10G switch.

FastCluster 3000 SERIES Hybrid Computing platforms include one or several VXS-M16 switch modules supporting StarGate and XL-Gate VXS payloads. Packaged into single or multiple VXS chassis, these systems deliver scalable bi-section bandwidth, backplane serial point-to-point reconfiguration and interoperability.
