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 for a wagering game; and
a power regulator operative to alter the power provided to the at least one processor amongst a plurality of power levels by altering the operating frequency of the at least one processor, the operating voltage of the at least one processor, or both the operating frequency and the voltage,
the altering responsive to a change in state of gameplay of the wagering game in progress on the gaming machine, the state of the gameplay including available credits on the gaming machine, a gameplay trigger event, or an outcome event 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 at least one processor.
3. The gaming machine of claim 2 , wherein the application software writes to a set of registers on the at least one processor.
4. 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 game activity parameters.
5. The gaming machine of claim 4 , wherein the plurality of power states include a low power state, a high power state, and at least one intermediate power state.
6. The gaming machine of claim 1 , wherein the operating voltage is altered by a voltage regulator in communication with a plurality of voltage pins connected to the at least one processor.
7. 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 wagering game is being played on the gaming machine, the at least one processor for executing gameplay;
receiving a wager from a player of the gaming machine;
altering the power consumption level of the at least one processor to a second power consumption level by altering the operating frequency of the at least one processor, the operating voltage of the at least one processor, or both the operating frequency and the voltage,
the altering based on a change in state of the gameplay of the wagering game being played, the state of the gameplay including available credits on the gaming machine, a gameplay trigger event, or an outcome event of the gameplay.
8. The method of claim 7 , wherein the steps of maintaining and altering the power consumption level of the at least one processor are performed by a power regulator.
9. The method of claim 8 , wherein the power regulator comprises application software stored on a memory device in communication with the at least one processor.
10. The method of claim 9 , wherein the application software includes a plurality of power states comprising an operating system policy.
11. The method of claim 10 , wherein each of the power states is associated with at least one game activity parameter monitored by the application software.
12. The method of claim 7 , wherein the operating voltage is altered by a voltage regulator in communication with a plurality of voltage pins connected to the at least one processor.
13. The method of claim 7 , wherein the first power consumption level represents a lower power state of the gaming machine than the second power consumption level.
14. A non-transitory computer readable storage device with instructions stored thereon, which when executed by at least one processor of a gamine machine, cause the gamine machine to:
maintain a first power consumption level of the least one processor of the gaming machine upon determining a wagering game is being played on the gaming machine;
alter the power consumption level of the at least one processor to a second power consumption level by altering the operating frequency of the at least one processor, the operating voltage of the at least one processor, or both the operating frequency and the voltage,
the altering based on a change in state of the gameplay of the wagering game being played, the state of the gameplay including available credits on the gaming machine, a gameplay trigger event, or an outcome event of the gameplay.
