Abstract
A computing device apparatus facilitates use of a deep low power mode that includes powering off the device's CPU by including a hardware implemented process to trigger storage of data from the device's volatile storage elements in non-volatile memory in response to entering the low power mode. A hardware based power management unit controls the process including interrupting a normal processing order of the CPU and triggering the storage of the data in the non-volatile memory. In response to a wake-up event, the device is triggered to restore the data stored in the non-volatile memory to the volatile memory prior to execution of a wake up process for the CPU from the low power mode. The device includes a power storage element such as a capacitor that holds sufficient energy to complete the non-volatile data storage task prior to entering the low power mode.
