This paper provides a methodology for estimating the proton static saturation cross-section for multi-bit upsets (MBUs) in Xilinx FPGAs and describes a methodology for determining MBUs’ effects on TMRprotected circuits. Experimental results are provided.
This paper presents proton and heavy ion static results for the latest Xilinx field-programmable gate arrays (FPGAs). The paper analyzes static bit cross-sections, resources, multiple-bit upsets (MBUs) and angular effects.
This paper provides a methodology for estimating the proton and heavy ion static saturation crosssections for multi-bit upsets (MBUs) in Xilinx fieldprogrammable gate arrays (FPGAs) and describes a methodology for determining MBUs’ effects on triplemodular redundancy (TMR) protected circuits. Experimental results are provided.
Problems with terrestrial-based neutron radiation from cosmic rays have become more commonplace. While the incident rate from neutron radiation is lower than space-based radiation, physics, system design and system locations have combined to make systems increasingly vulnerable to terrestrial radiation. FPGA systems are particularly sensitive to neutron… (More)
This paper provides information regarding the use of the Xilinx Virtex-4 field-programmable gate array in a spacecraft deployed to low-earth orbit. The results are compared to pre-deployment accelerated and fault-injection testing.
This work details a process-portable test chip, fabricated in 65nm CMOS, specifically designed to measure radiation-induced soft error rate (SER) during operation at near-threshold. A variety of SRAM, register file (RF), and digital logic test structures are included that provide a comprehensive assessment of circuit sensitivities to radiation at low… (More)
We are rapidly approaching an inflection point where the conventional target of producing perfect, identical transistors that operate without upset can no longer be maintained while continuing to reduce the energy per operation. With power requirements already limiting chip performance, continuing to demand perfect, upset-free transistors would mean the end… (More)
The combination of hardware acceleration and flexibility make FPGAs important to image processing applications. There is also a need for efficient, flexible hardware/software codesign environments that can balance the benefits and costs of using FPGAs. Image processing applications often consist of a pipeline of components where each component applies a… (More)
ARMs and microcontrollers are low-cost, low-power microprocessors that are frequently used in embedded computing. While not immune to the naturally occurring radiation environment in space, these microprocessors can be worthwhile replacements for space-grade microprocessors for non-mission-critical computational tasks. In this paper results from radiation… (More)
Using reconfigurable, static random-access memory (SRAM) based field-programmable gate arrays (FPGAs) for spacebased computation has been a very active area of research for the past decade. Because these commercially-available devices are only radiation-tolerant in terms of total ionizing dose and single-event latchup, these devices must be qualified for… (More)
