Abstract
A particular method includes, prior to issuing a recommendation by an adaptive voltage scaling (AVS) system, performing a first iteration of an AVS operation to sample characteristics of a semiconductor device to determine a first adjustment recommendation. The method further includes performing at least one additional iteration of the AVS operation to determine at least one additional adjustment iteration. When a threshold number of consecutive adjustment recommendations are consistent, the method includes issuing the recommendation by the AVS system.
Claims46
A method comprising:
- prior to issuing a recommendation by an adaptive voltage scaling (AVS) system:
- performing a first iteration of an AVS operation to sample characteristics of a semiconductor device to determine a first adjustment recommendation;
- and
- performing at least one additional iteration of the AVS operation to determine at least one additional adjustment recommendation;
- and
- in response to the first adjustment recommendation and each of the at least one additional adjustment recommendations being consistent, issuing the recommendation by the AVS system.
An apparatus comprising:
- an adaptive voltage scaling (AVS) system comprising:
- multiple sensors configured to sample characteristics of a semiconductor device;
- and
- a controller coupled to the sensors and configured to determine an adjustment recommendation for each iteration of an AVS operation that includes sampling the characteristics,
- wherein the controller is further configured to issue a recommendation in response to a threshold number of consecutive adjustment recommendations being consistent.
An apparatus comprising:
- means for sampling characteristics of a semiconductor device;
- means for determining an adjustment recommendation for each iteration of an adaptive voltage scaling (AVS) operation that includes sampling the characteristics;
- and
- means for issuing a recommendation in response to a threshold number of consecutive adjustment recommendations being consistent.
A computer-readable storage device comprising instructions that, when executed by a processor, cause the processor to:
- prior to issuing a recommendation by an adaptive voltage scaling (AVS) system:
- perform a first iteration of an AVS operation to sample characteristics of a semiconductor device to determine a first adjustment recommendation;
- and
- perform at least one additional iteration of the AVS operation to determine at least one additional adjustment recommendation;
- and
- in response to the first adjustment recommendation and each of the at least one additional adjustment recommendations being consistent, issue the recommendation by the AVS system.
