Multi-sampling judgment method for fault-tolerant filtering based on remainder check

Abstract

The invention provides a multi-sampling judgment method for fault-tolerant filtering based on remainder check, which solves the problem of residual error in a fault-tolerant filtering method based on remainder check in the prior art. When filtering output data of a first branch circuit are unequal to filtering output data of a second branch circuit but the filtering output data of the two branch circuits are the same by obtaining a remainder after division, and one error branch circuit cannot be judged once, the data can be temporarily stored in a cache, other data are continued to be processed and subjected to multiple judgment until one datum in the data by obtaining the remainder after division of the filtering output data of the first branch circuit and the filtering output data of the second branch circuit is not the same as a reference datum, and at the time, the branch circuit in error and the branch circuit with a correct processing result can be judged, so that the problem of residual error is avoided.

Description

technical field [0001] The present application relates to error-tolerant signal processing technology, in particular to a multi-sampling decision method in error-tolerant filtering processing based on remainder checking. Background technique [0002] Radiation will affect the performance of the device, which may cause errors in the output data of the device. For example, the signal processing equipment carried on some satellites is often affected by space radiation, resulting in signal processing errors. In order to solve this problem, fault-tolerant signal processing technology has emerged. [0003] Triple-mode redundancy (TMR) technology is widely used in fault-tolerant signal processing in radiation environments. TMR uses three identical modules to perform the same filtering operation on the input data, and determines the final output through the majority selector at the output end, completely eliminating the influence of a single branch failure on the signal processing ...
