Reconfigurable Processor Node

Reconfigurable Processor Node

Modular Processor for Space Applications Building-Block Processing Tailorable to Mission Needs

The RPN can be used to flexibly configure spacecraft processing. Using AFRL’s Space Plug & Play Avionics (SPA) standards, a data-centric network of nodes may be created. Applications may be distributed based on available processor load and restarted upon failure, facilitating a robust, fault tolerant system. The RPN is suitable for subsystem support, including the support of payloads by providing local payload processing with a well defined interface to the core spacecraft data system. Through use of the SPA standards, the node is also usable as a network-based data store. In addition to the Spacewire-based interface, the node exposes RS-422 serial ports that may be used to interface to more traditional systems.
