SEMICONDUCTOR DEVICE AND METHOD FOR CONTROLLING THE SAME

摘要

A pulse counting unit outputs a pulse count signal obtained by counting pulses of a first pulse signal received from a display module, and resets the pulse count signal when a value of the pulse count signal reaches an upper limit value. A mask pulse signal generation unit generates a mask pulse signal having a pulse corresponding to a reset period of the pulse count signal. A logical operation unit performs an AND operation on the first pulse signal and the mask pulse signal. A pulse signal generation unit uses a signal output by the logical operation unit to generate a second pulse signal having substantially the same pulse width as that of the first pulse signal. The pulse rate of the second pulse signal is substantially the same as a frame rate of multimedia data to be reproduced in the display module.

1. A semiconductor device, comprising:
a pulse counting unit configured to output a pulse count signal obtained by counting pulses of a first pulse signal received from a display module, and reset the pulse count signal when a value of the pulse count signal reaches a preset upper limit value; a mask pulse signal generation unit configured to generate a mask pulse signal having a pulse corresponding to a reset period of the pulse count signal; a logical operation unit configured to perform an AND operation on the first pulse signal and the mask pulse signal; and a pulse signal generation unit configured to generate a second pulse signal using a signal output by the logical operation unit, wherein the second pulse signal has substantially the same pulse width as a pulse width of the first pulse signal, wherein a pulse rate of the second pulse signal is substantially the same as a frame rate of multimedia data to be reproduced in the display module.
