一种提高通用处理模块数据完整性的设计方法

A Design Method for Improving Data Integrity of General Processing Module

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。

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.
