Dynamic power management in a gaming machine
View Patent ↗A gaming machine for conducting a wagering game includes a value input device for receiving a wager and a processor for executing gameplay on the gaming machine. The processor has a plurality of power consumption levels. A power regulator is operative to alter the power consumption level of the processor amongst the plurality of power consumption levels. In an embodiment, the power regulator comprises application software stored on a memory device in communication with the processor.
1. A gaming machine comprising:
a value input device for receiving a wager;
at least one processor for executing gameplay on the gaming machine, the processor having a plurality of power consumption levels;
commencing gameplay on the gaming machine;
determining an outcome of the gameplay; and
a power regulator operative to alter the power consumption level of the processor amongst the plurality of power consumption levels, wherein the power regulator is responsive to the outcome of the gameplay.
2. The gaming machine of claim 1 , wherein the power regulator comprises application software stored on a memory device in communication with the processor.
3. The gaming machine of claim 2 , wherein the application software writes to a set of registers on the processor.
4. The gaming machine of claim 1 , wherein the processor has an operating frequency and an operating voltage.
5. The gaming machine of claim 4 , wherein the power regulator alters the power consumption level of the processor by altering the operating frequency, the operating voltage, or both.
6. The gaming machine of claim 5 , wherein the operating voltage is altered by a voltage regulator in communication with a plurality of voltage pins connected to the processor.
7. The gaming machine of claim 2 , wherein the application software comprises an operating system policy including a plurality of power states, each power state associated with at least one of the game activity parameters.
8. The gaming machine of claim 7 , wherein the plurality of power states include a low power state, a high power state, and at least one intermediate power state.
9. A method of conducting a wagering game on a gaming machine, the method comprising:
maintaining a first power consumption level of at least one processor of the gaming machine upon determining the gaming machine is not being played, the processor for executing gameplay;
receiving a wager from a player of the gaming machine;
altering the power consumption level of the processor to a second power consumption level upon determining game play has commenced; and
altering the power consumption level of the processor to a third power consumption level upon determining a winning outcome occurs on the gaming machine.
10. The method of claim 9 , wherein the steps of maintaining and altering the power consumption level of the processor are performed by a power regulator.
11. The method of claim 10 , wherein the power regulator comprises application software stored on a memory device in communication with the processor.
12. The method of claim 11 , wherein the application software includes a plurality of power states comprising an operating system policy.
13. The method of claim 12 , wherein each of the power states is associated with at least one game activity parameter monitored by the application software.
14. The method of claim 9 , wherein the processor has an operating frequency and an operating voltage.
15. The method of claim 14 , wherein the altering step comprises altering the operating frequency, the operating voltage, or both.
16. The method of claim 15 , wherein the operating voltage is altered by a voltage regulator in communication with a plurality of voltage pins connected to the processor.
17. The method of claim 9 , wherein the first power consumption level represents a lower power state of the gaming machine than the second power consumption level.
18. A computer readable storage medium encoded with instructions for directing a gaming device to perform the method of claim 9 .
