VXS Cover VME Switched Serial “VXS” is a trademark of VITA

VXS Overview Adds switched serial interconnect(s) to the VME architecture coincident with the VMEbus parallel bus. Employs standard open technology for the serial switched links. Accommodates multiple switched serial technologies, but not necessarily at the same time. Utilizes MULTIGIG RT 2 connector in P0 position. Demonstrated to support 10 Gb/s. Pulls additional DC power onto each VME card over existing P1/P2 pins (VITA 1.7). Maintains backward compatibility.

Why VXS? The most demanding applications (e.g. SPE, radar, sonar, image processing, etc.) require: –High performance, scalable processing power –Very high data transfer capabilities –Extremely low latency Currently these applications make use of: –VMEbus for “control plane” communication –A proprietary or quasi-standard bus for “data plane” communication Standard interfaces are now able to address these needs and provide: –Less Contention –Increased Scalability –Less Routing Real Estate –Higher Bandwidth –Low Latency
