Reconfigurability is a key element to extracting the most from any spacecraft or spacecraft subsystem. It allows systems to become more autonomous, maximizes their usage once deployed, and delays obsolescence by allowing new uses of the spaceborne asset, often in ways not envisioned by its creators. In the past, reconfigurability has been mostly present in the software side of the spaceborne systems. Hardware consisted of standard and hard-wired application specific components and short of a shuttle repair mission, one could not reconfigure the hardware. Advancements in field programmable devices now offer increased flexibility to the user. For example, BAE Systems continues to expand a set of reconfigurable processing building blocks, now in their third generation, centered on its RAD750¿ processor products, standard form factors and interfaces. These blocks may be utilized to create various processing architectures, be extended to other I/O interfaces and be reprogrammed and reconfigured at any or all of the software, interface or FPGA levels. A significant infrastructure has been developed making it easier for the application to utilize reconfigurable elements. To this end, communication, control and low level management interfaces are defined and implemented within the building blocks allowing the user more time to develop and integrate the mission of the system. In creating these system building blocks for spacecraft payloads, we developed comprehensive verification and validation approaches that not only complete the development of the building blocks but also assures higher level integration and provides a testbed for future use.
