摘要: A wireless device includes a voltage regulator circuit configured to generate a voltage signal of a first input voltage, and a wireless baseband processing circuitry (WBPC) coupled to the voltage regulator circuit to receive the voltage signal. The WBPC is configured to process signals for transmission or reception using wireless technology. The WBPC includes a sub-system processor circuit configured to detect a wireless bandwidth of an application executing on an application processor of the wireless device; determine a second input voltage based on the wireless bandwidth of the application and a maximum voltage supported by the WBPC; and encode a feedback signal for communication to the voltage regulator circuit. The feedback signal causes adjustment of the voltage signal to the second input voltage.

摘要: Particular embodiments described herein provide for an electronic device that includes two or more displays and a BIOS. On startup, before the premem state and MRC initialization of the boot process, the BIOS causes power to be enabled to two or more displays. A display engine determines if a hot plug for each display is asserted and for each display where the hot plug was not asserted, the path to the display where the hot plug was not asserted is closed. In an example, the BIOS communicates the signal to power enable the first display and the second display after general-purpose input/output initialization during the boot process. After the premem stage and MRC initialization are completed, the first display and the second display are both configured to begin to display pixels.
