Implementation of middleware switch ASIC processor

The new spacecraft area network (SCAN) system for internal satellite communication provides the data transfer between different satellite components. The middleware (MW) switch processor is a main part of a new proposed approach. Instead of current board computer based systems, the new data transfer approach based on network provides more reliable solution. The processor is currently in fabrication process in the 250 nm IHP technology. This paper introduces the description of MW switch architecture, a comparison between possible architecture approaches and characteristics of the implemented MW Switch processor.
