Abstract
Embodiments including systems, methods, and apparatuses associated with increasing the power efficiency of one or more components of a computing system. Specifically, the system may include a processor chip which may include an on-die voltage regulator (VR) configured to supply a voltage to a component of the processor chip. The processor chip may be coupled with a dynamic random access memory (DRAM). The system may further include an external VR coupled with the DRAM. A BIOS may be configured to regulate the voltage output of one or both of the on-die VR and/or the external VR. Other embodiments may be described or claimed.
Claims20
An apparatus comprising:
- an analog front end (AFE);
- and
- a voltage regulator coupled with the AFE, the voltage regulator configured to supply a voltage to the AFE;
- wherein the voltage regulator is configured to dynamically alter the voltage to reduce power consumption of the AFE based at least in part on a result of a training loop performed on system power up or system reset.
A method comprising:
- setting, by a basic input/output system (BIOS), a voltage output of an on-die voltage regulator to a first voltage;
- identifying, by the BIOS, an occurrence of a margin failure at an analog front end (AFE) configured to receive the first voltage;
- and
- adjusting, by the BIOS in response to the occurrence of the margin failure, the voltage output of the on-die voltage regulator by an increment.
A system comprising:
- a memory controller coupled with a dynamic random access memory (DRAM);
- an on-die voltage regulator to supply a first voltage to an analog front end (AFE) coupled with the DRAM;
- an external voltage regulator configured to supply a second voltage to the DRAM;
- wherein the on-die voltage regulator and the external voltage regulator are configured to alter the first voltage or the second voltage based at least in part on a signal from a basic input/output system (BIOS).
