摘要： Field-programmable gate arrays (FPGAs) have been shown to provide high computational density and efficiency for many computing applications by allowing circuits to be customized to any application of interest. FPGAs also support programmability by allowing the circuit to be changed at a later time through reconfiguration. There is great interest in exploiting these benefits in space and other radiation environments. FPGAs, however, are very sensitive to radiation and great care must be taken to properly address the effects of radiation in FPGA-based systems. This paper will highlight the effects of radiation on FPGA-based systems and summarize the challenges in deploying FPGAs in such environments. Several well-known mitigation methods will be described and the unique ability of FPGAs to customize the system for improved reliability will be discussed. Finally, two case studies summarizing successful deployment of FPGAs in radiation environments will be presented.

Improved electro-optic chaotic system with nonlinear electrical coupling
摘要： Design disjunction is developed to offer a broad coverage, high resolution, and low overhead approach to online diagnosis and recovery of recon?gurable fabrics. Design disjunction leverages the condensed diagnosability of T logic resources to achieve self-recovery using partial recon?guration in O(log T ) steps. Recon?guration is guided by the constructive property of f-disjunctness which forms O(log T ) resource groups at design-time. Resolution of f simultaneous resource faults is shown to be guaranteed when the resource groups are mutually f-disjunct. This extends run-time fault resilience to a large resource space with certainty for up to f faults using a decision-free resolution process that also provides a high likelihood of identifying the fault’s location to a ?ne granularity. Finally, design disjunction is parameterized to accommodate the low coverage issue of functional testing for which inarticulate tests can otherwise impair fault isolation. Experimental results for MCNC and ISCAS benchmarks on a Xilinx 7-series ?eld programmable gate array (FPGA) demonstrate f-diagnosability at the individual slice level with a minimum average isolation accuracy of 96:4 percent (94:4 percent) for f ? 1 (f ? 2). Results have also demonstrated millisecond order recovery with a minimum increase of 83:6 percent in fault coverage compared to N-modular redundancy (NMR) schemes. Recovery is achieved while incurring an average critical path delay impact of only 1:49 percent and energy cost roughly comparable to conventional two-MR approaches.
