VARIABLE DELAY INSTRUCTION FOR IMPLEMENTATION OF TEMPORAL REDUNDANCY

机译:实施时间冗余的可变延迟指令

摘要

PPROBLEM TO BE SOLVED: To provide a method for detecting computational errors in a digital processor executing a program. PSOLUTION: The program is divided into a plurality of computation sections 207, and two functionally identical code segments, respectively comprising a primary segment 210 and a secondary segment 215, are generated for one of the computation sections 207. The primary segment 210 is executed, after which a temporal diversity timer 208 is started. The secondary segment 215 is then executed upon expiration of the timer 208. The respective results of execution of the primary segment 210 and the secondary segment 215 are compared (310) after completion of execution of the secondary segment, and an error indication is provided if the respective results are not identical.

要解决的问题:提供一种用于在执行程序的数字处理器中检测计算错误的方法。

解决方案:程序被划分为多个计算部分207,并且为其中一个计算部分207生成了两个功能相同的代码段,分别包括一个主要段210和一个次要段215。主要段210在执行之后,启动时间分集定时器208。然后,在计时器208到期时执行次要段215。在次要段执行完成之后,比较(310)主要段210和次要段215的执行结果,并提供错误指示。各自的结果并不相同。
