Abstract: A system and method reduce bootup latency in systems that run Auto operating systems (Auto OS). When, or just prior to, the system controller initiating suspend-to-disk (S2D) process entry, the system controller causes a memory controller to determine the percentage of volatile memory that is currently occupied and compares that percentage of occupancy to a predetermined threshold (TH) percentage. If the percentage of occupancy exceeds the predetermined TH percentage, then the memory controller tags apps that are occupying volatile memory as either background apps or foreground apps, terminates the background apps, clears volatile memory of any instructions and data associated with the terminated background apps, takes a snapshot of the state of volatile memory after the terminated background apps and associated data have been cleared, and saves the snapshot to a designated storage location in nonvolatile memory before entering hibernate mode.
