On-line testing method of floating-point computing circuits

Drozd A. V., Oginskaja E. V.

The problem of on-line testing for floating-point circuits, which execute approximate mantissa processing, is considered. The checking method by inequalities for mantissas multiplier is proposed. Operation result compares with its high and low borders, executed by operands. The method detects errors in dependence on their size and raises reliability of the check of results, reducing rejection of authentic results.
