Abstract
The present disclosure provides a method and a device for processing PWM data, so as to reduce the size of the PWM data. The method includes: dividing pulse widths in the PWM data into at least one pulse width group; determining a convergence pulse width for each of the at least one pulse width group, herein each of the at least one pulse width group converges around a same pulse width, respectively; replacing each of the at least one pulse width group with the corresponding convergence pulse width; and representing the PWM data by using the convergence pulse widths. 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.
