Embodiment Construction
[0027] In order to solve the power consumption problem of the baseband chip of the mobile phone, the invention improves the power saving capability of the chip, prolongs the use time of the mobile phone, and simultaneously maintains the time synchronization between the mobile phone and the base station when the chip returns to the normal mode from the power saving mode. Such as figure 1 As shown, the working process of the power saving mode of the present invention is as follows:
[0028] 1. Before entering the power saving mode, first start the H calculation circuit; the function of the H circuit is to calculate the multiple value relationship between the system working clock and the slow clock, and to calculate the time of the power saving mode and the synchronization relationship when exiting the power saving mode .
[0029] 2. After the calculation of the H circuit is completed, a command to enter the power saving mode is issued;
[0030] 3. The duration of the power-sav...
