Abstract
Disclosed is a CORDIC circuit in which scale correction process is divided into two stages: rough correction and fine correction, and a second-process of a pseudo-rotation process is performed in parallel with the fine scale correction. A range of the fine scale correction is set so that it is not necessary to perform a scale correction with regard to a remaining rotation angle of the first half of the pseudo-rotation process.
