Abstract
Examples are disclosed for switching frequency control of an on-chip or integrated voltage regulator. In some examples, a switch frequency of an integrated voltage regulator may be monitored. A determination of whether the monitored switch frequency causes radio signal interference may cause the switch frequency to be adjusted to eliminate or reduce the radio signal interference. Other examples are described and claimed.
Claims19
An apparatus comprising:
- a processor circuit;
- a monitor module to be executed by the processor circuit to monitor an integrated voltage regulator (IVR) switching frequency for an IVR capable of regulating voltage for a microprocessor co-located on-chip with the IVR;
- a report module to be executed by the processor circuit to receive radio frequency information for one or more wireless components co-located on-chip with the IVR or proximate to the IVR;
- an interference module to be executed by the processor circuit to determine whether the monitored IVR switching frequency causes radio signal interference to the one or more wireless components based on the radio frequency information;
- and
- an adjust module to be executed by the processor circuit to adjust the IVR switching frequency based on the determination of the interference module.
A computer-implemented method comprising:
- monitoring a switching frequency for an on-chip voltage regulator;
- receiving radio frequency information for one or more wireless components co-located on-chip with the voltage regulator or proximate to the voltage regulator;
- determining whether the monitored switching frequency causes radio signal interference to the one or more wireless components based on the radio frequency information;
- and
- adjusting the switching frequency based on the determination.
At least one machine readable medium comprising a plurality of instructions that in response to being executed on a system causes the system to:
- monitor an integrated voltage regulator (IVR) switching frequency for an IVR capable of regulating voltage for one or more on-chip components;
- receive radio frequency information for one or more wireless components co-located on-chip with the IVR or proximate to the IVR;
- determine whether the monitored IVR switching frequency causes radio signal interference to the one or more wireless components based on the radio frequency information;
- and
- adjust the IVR switching frequency based on the determination.
