A report discusses integrating multiple memory modules on the high-speed serial interconnect (IEEE 1393) that is used by a spacecraft’s inter-module communications in order to ease data congestion and provide for a scalable, strong, flexible system that can meet new system-level mass memory requirements.

Using the JPL 1393 Ring Bus Interconnect to link computer elements, I/O, and memory allows any element to communicate with any other element. Besides providing a consistent approach to exchanging data, it inherently has a layer of abstraction that allows for better system and software design. This new architecture is fault-tolerant and provides a large range of scalability while supporting flexible spacecraft architectures that are currently being investigated.

This work was done by Brian Cox, Jeffrey Mellstrom, and Terry Wysocky of Caltech for NASA’s Jet Propulsion Laboratory.
