Area efficient and accurate CORDIC processor for motor control drive

The CORDIC algorithm can compute linear, trigonometric and hyperbolic functions. Mathematical identities also allow computation of other functions. Our primary aim is applications in motor control drive, such as concordia/park transform, pulse width modulation (PWM)... In this paper, we present an i...

Description
Summary:The CORDIC algorithm can compute linear, trigonometric and hyperbolic functions. Mathematical identities also allow computation of other functions. Our primary aim is applications in motor control drive, such as concordia/park transform, pulse width modulation (PWM)... In this paper, we present an implementation of a fixed-point processor based on CORDIC algorithm. Large numerical errors due to such systems are eliminated by including additional hardware. We estimate the performances of our CORDIC scheme and compare it with previously proposed scheme and show that it provides a significant saving in area.
