Event carry out resolving to generate corresponding context pattern.
Subsequently, all of context pattern current to system of the moderator 410 in watch-dog 40
Merge, to judge current system conditions.
When user is without operation, system mode is the most as shown in table 2:
| System mode | Context pattern |
| State of temperature | Room temperature (temperature < 65 degrees Celsius) |
| Click event | No touch event |
| Acceleration transducer | Static |
| Lcd screen | Bright screen |
| … | … |

DVFS system.DVFS system determines that final frequency configuration strategy is as follows:
CPU variable frequency range is from 156MHz to 1248MHz, and raising frequency threshold value is 90%；
GPU variable frequency range is from 156MHz to 624MHz, and raising frequency threshold value is 90%；
DDR variable frequency range is from 156MHz to 533MHz, and raising frequency threshold value is 65%.
When user carries out slide on the touchscreen, system mode is the most as shown in table 3:
| System mode | Context pattern |
| State of temperature | The most overheated (master chip > 65 degree Celsius) |
| Click event | Touch slip event |
| Acceleration transducer | Static |
| Lcd screen | Bright screen |
| … | … |
Now, the lifter 420 in watch-dog 40 according to the context pattern shown in table 3,
Corresponding frequency configuration strategy is selected from the frequency configuration strategy set 50 shown in above table 1
Level#1 and Level#4.Lifter 420 will be according to merging algorithm as follows in this case
Generate final strategy.
The amalgamation result of frequency configuration strategy Level#1 with Level#4 is:
CPU variable frequency range is from 416MHz to 832MHz, and raising frequency threshold value is 90%；
GPU variable frequency range is from 312MHz to 416MHz, and raising frequency threshold value is 80%；
DDR variable frequency range is from 312MHz to 416MHz, and raising frequency threshold value is 40%.
Affect as follows finally for scenario A and B:
User's scenario A:
Based on the input parameter after existing DVFS frequency conversion algorithm and adjustment of the present invention (from carrying
Rise the frequency configuration strategy of device 420), DVFS frequency conversion result is that DDR clock frequency is
312MHz, GPU clock frequency is 312MHz.
User's scenario B:
Based on the input parameter after existing DVFS frequency conversion algorithm and adjustment of the present invention, DVFS
Frequency conversion result be DDR clock frequency be 312/416MHz, GPU clock frequency be 312MHz.
Performance/power consumption assessment:
For scenario A, video, without card, meets performance and power consumption requirements.
For scenario B, when user clicks on, DDR frequency can meet performance requirement with rapid increase,
Game role jumps and links up without card, and GPU processes non-over loading simultaneously, stable at 312MHz.
Than existing DVFS algorithm, on the premise of meeting performance requirement, energy consumption has no and significantly carries
Rise.
