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
