An operating system or firmware of the device may cause one or more pages of the volatile memory to be treated, by applications executing on the computing device, as non-volatile memory pages. A maximum number of pages that may be treated as non-volatile may be determined based on an amount of energy available in a battery and an amount of energy needed to transfer a page of memory to the non-volatile storage device.

Abstract: A system for controlling a subsystem of a vehicle includes a memory, a first processor, and a second processor. The first processor allocates a portion of the memory upon booting to perform operations to control the subsystem and generates an indication when an amount of memory used from the allocated portion of the memory is greater than or equal to a threshold. The first processor monitors times when the vehicle is turned on and off and determines a time period during which the vehicle remains turned off. After the vehicle is turned off, the first processor enters a power save mode. The memory and the second processor continue to receive power. During the time period, on receiving the indication, the second processor wakes up the first processor, which performs a reboot operation, reallocates the memory, and reenters the power save mode. The memory continues to receive power.

Abstract: Various embodiments of the present technology provide methods for boosting a voltage differential of an energy storage by using a boost component, determining a server system being switched to a boost mode, and discharging the energy storage to provide additional power supplies to the server system during the boost mode. In some embodiments, processing demands of a server system can be monitored. In response to determining that a boost mode is needed to support processing demands of the server system or detecting a component being a bottleneck in processing pipelines of the server system, a boost activation signal can be generated. The boost activation signal can cause a CPU, the bottleneck component, or another component of the server system to operate under a higher clock speed such that a higher processing capacity can be achieved.
