ERROR CONTROL USING THRESHOLD BASED COMPARISON OF ERROR SIGNATURES

摘要

A technique is provided for system reliability. An input is received, and a computation operation on the input is repeated to generate multiple output values. The multiple output values are stored in a table along with a number of hits for each distinct output value in the multiple output values, and the number of hits indicates a number of times each distinct output value was generated by the repeating. A reliability circuit checks whether the number of hits for any one distinct output value meets a confidence threshold. Based on meeting the confidence threshold for the number of hits, the any one distinct output value is output. Based on the number of hits for the any one distinct output value not meeting the confidence threshold, the computation operation is continuously repeated on the input until the number of hits for the any one distinct output value meets the confidence threshold.

1. A computer system for implementing system reliability, the system comprising:
a memory; and a processor, communicatively coupled to said memory, the computer system configured to perform a method comprising: receiving an input; repeating a computation operation on the input to generate multiple output values; storing the multiple output values in a table along with a number of hits for each distinct output value in the multiple output values, the number of hits indicating a number of times each distinct output value was generated by the repeating; checking, by a reliability circuit, whether the number of hits for any one distinct output value meets a confidence threshold; based on meeting the confidence threshold for the number of hits for the any one distinct output value, outputting the any one distinct output value; and based on the number of hits for the any one distinct output value not meeting the confidence threshold, continuing to repeat the computation operation on the input until the number of hits for the any one distinct output value meets the confidence threshold.
