Apparatus power control
The present disclosure includes apparatuses and methods for apparatus power control. A number of embodiments include determining a power profile for each of a number of commands in a command queue that are ready for execution and selecting a portion of the number of commands in the command queue for execution based on the power profiles of the number of commands to control power consumption in the apparatus.
1. A method for controlling power in an apparatus, comprising:
determining a power profile for each of a number of commands in a command queue that are ready for execution, wherein the power profile for each of the number of commands includes power consumption information; and
selecting a portion of the number of commands in the command queue for execution based on the power profiles of the number of commands to control power consumption in the apparatus such that a particular average power level for the apparatus is achieved.
2. The method of claim 1 , wherein the method includes selecting an additional number commands in the command queue for execution to control power consumption of the apparatus such that a peak power level for a particular amount of time is achieved.
3. The method of claim 1 , wherein determining a power profile for each of a number of commands comprises determining the power profile for a respective one of the number of commands using a type of the respective command.
4. The method of claim 1 , wherein determining a power profile for each of a number of commands comprises determining the power profile for a respective one of the number of commands using a length of time the respective command has been in the command queue.
5. The method of claim 1 , wherein determining a power profile for each of a number of commands comprises determining the power profile for a respective one of the number of commands using a parameter associated with a channel and/or memory device on which the respective command is to be executed.
6. The method of claim 1 , wherein selecting the portion of the number commands in the command queue for execution comprises selecting the portion of the number of commands based on a temperature of the apparatus.
7. The method of claim 1 , wherein the method includes executing the portion of the number of commands that were selected.
8. The method of claim 1 , wherein determining the power profile for each of the number of commands in the command queue that are ready for execution comprises determining the power profile at a controller.
9. A method for controlling power in an apparatus, comprising:
receiving a number of commands ready for execution in a command queue;
determining a power profile for each of the number of commands; and
selecting a portion of the number of commands for execution based on the determined power profiles by analyzing the power profiles to determine a combination of commands that when executed consume power at a particular level that is no more than a particular average power level.
10. The method of claim 9 , wherein analyzing the power profiles includes determining a combination of commands that when executed consume power at a level that is no more than a particular average power level.
11. The method of claim 9 , wherein analyzing the power profiles includes determining a combination of commands that when executed consume power at a peak level for no more than a particular period of time.
12. The method of claim 9 , wherein analyzing the power profiles includes prioritizing a respective one of the commands based on a length of time the respective command has been in the command queue.
13. The method of claim 9 , wherein analyzing the power profiles includes prioritizing the commands based on command type and device parameters.
14. The method of claim 9 , wherein selecting the portion of the number of combinations for execution is responsive to the sum of all the power profiles being greater than a particular average power level.
15. An apparatus, comprising:
a number of memory cells; and
a controller coupled to the number of memory cells and configured to:
determine a power profile for each command of a number of commands in a command queue that are ready for execution;
determine a sum of the power profiles for each of a number of combinations of commands to determine an amount of power the apparatus will consume during execution of each combination of commands; and
select one of the number of combinations of commands for execution based on the amount of power the apparatus will consume during execution of the selected combination of commands, wherein the selected combination of commands consume an amount of power that is no more than a particular average power level.
16. The apparatus of claim 15 , wherein the controller is configured to update the power profiles as commands are executed.
17. The apparatus of claim 15 , wherein the controller is configured to update the power profiles as commands are received by the controller.
18. A method for controlling power in an apparatus, comprising:
receiving a number of commands ready for execution in a command queue;
determining a power profile for each of the number of commands; and
selecting a portion of the number of commands for execution based on the determined power profiles by analyzing the power profiles to determine a combination of commands that when executed consume power at a particular level, wherein selecting the portion of the number of combinations for execution is responsive to the sum of all the power profiles being greater than a particular average power level.
19. An apparatus, comprising:
a number of memory cells; and
a controller coupled to the number of memory cells and configured to:
determine a power profile for each command of a number of commands in a command queue that are ready for execution;
determine a sum of the power profiles for each of a number of combinations of commands to determine an amount of power the apparatus will consume during execution of each combination of commands; and
select one of the number of combinations of commands for execution based on the amount of power the apparatus will consume during execution of the selected combination of commands, wherein the selected combination of commands consume an amount of power that is greater than a particular average power level for no more than a particular period of time.
