Rats were trained in a previously validated behavioral vigilance task that required them to detect visual signals of variable length and to discriminate signal from nonsignal events. Baseline performance was characterized by a signal length-dependent ability to score hits, a decline in hits over time, and a correct rejection rate of approximately 70%. After(More)
— 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(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)
Radiation-tolerant computing is of great importance to the aerospace community because future missions demand more computational power. Of special interest to the aerospace community are flight computers implemented on static random-access-memory-based field-programmable gate arrays. Such computer systems allow the in-flight reconfiguration of hardware that(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)
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)
