ABSTRACT:
To provide a floating point arithmetic circuit for efficiently defecting an error, which has a large numerical error, with a less circuit amount, the floating point arithmetic circuit comprises a first arithmetic unit for outputting a first arithmetic result, a second arithmetic unit for outputting a second arithmetic result, and a comparison circuit for making a comparison between the first and the second arithmetic results by a predetermined bit width.
