    摘要： The present disclosure provides a method and a device for processing PWM data, so as to reduce the size of the learned PWM data. The method includes: determining (S101) a pulse width of each convergent point at which pulse widths converge around a same pulse width in learned PWM data; replacing (S102) each of the pulse widths converging around the corresponding same pulse width with the pulse width of the corresponding convergent point; generating (S103) a pulse-width query table containing the pulse width of each convergent point; and representing (S104) the PWM data by each index of each pulse width in the pulse-width query table. Through the technical solution, the size of the PWM data may be reduced, transmission speed of the PWM data may be improved, and the space for storing the PWM data may be decreased.
