Abstract: A hardware based motor controller may be used to generate chopped signals. The hardware based motor controller may decrease CPU bandwidth needed to perform functions related to motor control. In an aspect of the disclosure, a method and an apparatus are provided. The apparatus may be a motor controller for controlling a brushless motor. The motor controller may include a first carrier generator component for providing a first carrier. The motor controller may also include a first pulse generator component for providing a first pulse at a duty cycle. The first pulse generator component may be coupled to the first carrier generator component. Additionally, the first pulse generator may be configured to combine the first pulse with the first carrier to generate a first output pulse. Additionally, the first pulse generator may also be configured to output the first output pulse to drive a first leg of the brushless motor.
