应用重离子加速器和皮秒脉冲激光器开展Virtex-ⅡFPGA(Field Programmable Gate Array)单粒子效应加固方法有效性研究.实验结果表明,同时应用三模冗余和动态刷新加固方法能够完全纠正单粒子效应产生的功能错误.实验获得数据加密算法在不同单粒子效应加固方法下功能错误截面,发现少量的存储位翻转就可以导致程序功能错误;程序功能对存储位翻转较敏感.分析Virtex-ⅡFPGA不同加固方法在不同卫星轨道的有效性,同时应用动态刷新和三模冗余加固方法,可以完全校正由于存储位翻转造成的功能错误.重离子加速器和脉冲激光器实验结果同时表明,脉冲激光可以模拟重离子加速器研究单粒子效应加固方法有效性.
The application of heavy ion accelerator and picosecond pulsed laser to study the effectiveness of the Virtex-ⅡFPGA (Field Programmable Gate Array) single-particle effect hardening method is studied.The experimental results show that the simultaneous application of the triple-mode redundancy and dynamic refreshment reinforcement method can completely correct the single particle effect Of the functional errors.Experimental data encryption algorithm in the different single-particle effect reinforcement method under the wrong section and found that a small amount of memory bit flip can lead to program error.Program function is more sensitive to the memory bit flip.Analysis of Virtex-ⅡFPGA different reinforcement methods The effectiveness of different satellite orbits and the application of dynamic refreshing and three-mode redundancy reinforcement method can completely correct the functional errors caused by the turning of memory bits.The experimental results of heavy ion accelerator and pulsed laser also show that pulsed laser can simulate heavy ion accelerator To study the effectiveness of single particle effect reinforcement method.
