发明名称 Firmware controlled dynamic voltage adjustment
摘要 Methods, apparatus, articles of manufacture, and systems for providing a supply voltage to an electronic component, such as a processor, are provided. An executable software component, such as system firmware, may access a voltage selection value embedded in the component and retrieve a voltage setting, from a table of voltage settings, using the embedded voltage selection value as an index. The software component may then configure a power supply, based on the voltage setting retrieved from the voltage selection table, to supply the component with an optimal supply voltage. For some embodiments, the voltage selection table may be replaced by downloading a new voltage selection table, thus, allowing changes to the component supply voltage without changing hardware.
