| 摘 要： | 航空电子产品中为了满足高安全等级应用的驻留需求，通用处理模块的数据完整性指标需要达到
Level A（10-9）级。基于当前元器件的可靠性和产品设计的复杂度，产品的数据完整性一般在10-3 到10-5 的水平，
无法满足产品的设计需求。本文提出了一种基于数据锁步的设计方法，该方法可用当前的软硬件资源在工程项
目中设计出满足高完整性要求的产品。

| Abstract: | In order to meet the residency requirements of high security level applications in avionics products, the data
integrity index of the general processing module needs to reach Level A (10-9). Based on the reliability of the current components
and the complexity of product design, the data integrity of the product is generally at the level of 10-3 to 10-5, which
cannot meet the design requirements of the product. A design method is proposed based on data lockstep, which can use
current software and hardware resources to design products that meet high integrity requirements in engineering projects. |

| Keywords: | data integrity lockstep general processing module redundancy |
