## Abstract

A device receives a first result that includes first data, and a second result that includes second data, and determines whether a comparator supports the first data and the second data. When the comparator supports the first data and the second data, the device utilizes the comparator to select comparison logic for the first data of the first result and for the second data of the second result, compares the first result and the second result, using the selected comparison logic, to determine whether the first result is equivalent to the second result, and outputs or stores the determination of whether the first result is equivalent to the second result.
