Application of FPGA in space electronics device
-
摘要: 介绍了几种常用于空间电子学设备的可编程逻辑器件 (FPGA), 基于空间环境特点, 分析了可编程逻辑器件在空间电子学设备中应用时需要考虑的特殊问题. 针对空间试验中经常出现的单粒子翻转事件(SEU), 介绍了一种基于冗余(FTMR) 的FPGA设计方法, 并通过实例给出了这种方法对系统性能和设计规模的影响.Abstract: This paper introduces several mainstream programmable logic devices used in space electronics equipment. In consideration of particular characteristics of space environment, special approaches should be used when using FPGA in space. Functional Triple Modular Redundancy (FTMR) approach in FPGA design has been introduced to protect design from the SEU (Single Event Upset) induced by radiation. Examples of FTRM are given to demonstrate the effects of this approach.
