A position sensitive radiation sensor was modeled, developed and fabricated then interfaced with a field programmable gate array (FPGA) to create a radiation hardened computing platform. The system exploits environmental information from the sensor in order to determine regions within the FPGA that may have been affected by radiation. The spatial radiation(More)
A SCOMPUTING systems have grownmore powerful, with a concomitant shrinking of their operational circuitry, the possibility of radiationinduced faults in the hardware has become an ever more pressing concern. This is especially true for systems that must operate outside the protection of the Earth’s atmosphere and magnetosphere. Spacecraft and planetary(More)
This paper describes the development of a SmallSat computer system that provides increased tolerance to radiation induced faults through a novel architecture implemented on commercial-off-the-shelf (COTS) Field Programmable Gate Arrays (FPGA). The computer system provides increased reliability, computational performance, and power efficiency at a fraction(More)
Thermal analysis was required in order to aid in the design and testing of a radiation tolerant computing (RTC) system using a radiation sensor. During development of the system, different test beds were employed in order to characterize the radiation sensor and its supporting electronic systems. The most common preliminary tests are high altitude balloon(More)
This paper describes the benchmarking of an FPGA-based computing system that uses partially reconfigurable tiles for real-time allocation of hardware resources. This system was developed for use in the aerospace industry in order to provide redundancy for fault mitigation and real-time hardware reallocation to reduce mass associated with separate functional(More)
A prototype system has demonstrated the capability to use a custom-designed multi-channel sensor to monitor high energy radiation strikes by coupling the silicon sensing elements with a radiation tolerant computer system. The computer system uses triple modular redundant soft processors and custom signal conditioning circuitry to monitor single event(More)
A custom FPGA-based, 1U CubeSat form-factor reconfigurable computing development platform has been designed and built for the purpose of implementing and testing multicore and multiprocessor systems. The platform was designed to leverage the active partial reconfiguration and configuration readback capabilities of the Xilinx Virtex-6 device. This enables(More)
