Field Programmable Gate Arrays are a widely used technology; however, they are generally limited in reprogrammability. Radiation hard, low power and high density ReProgramable FPGAs (RP-FPGAs) would be a tremendous asset in long duration missions. The ability to adapt to changeing mission profiles and on board capabilities is highly desirable. We herein propose to develop a RP-FPGA for flight use. In Phase I we will prove basic device concepts working with a leading FPGA manufacturer. In Phase II we will develop a viable demonstration prototype that will enable routine Phase III device manufacture.
