Abstract: Systems, methods, and computer programs are disclosed for detecting high-level functionality of an application executing on a computing device. One method comprises storing, in a secure memory on a computing device, a virtual address mapping table for an application. The virtual address mapping table comprises a plurality of virtual addresses in the application binary code mapped to corresponding target application functionalities. The application is registered with a high-level operating system (HLOS). During execution of the application binary code, the HLOS detects when one or more of the virtual addresses corresponding to the target application functionalities are executed based on the virtual address mapping table.

Abstract: Systems, methods, and computer programs are disclosed for scheduling decompression of an application from flash storage. One embodiment of a system comprises a flash memory device and a preemptive decompression scheduler component. The preemptive decompression scheduler component comprises logic configured to generate and store metadata defining one or more dependent objects associated with the compressed application in response to an application installer component installing a compressed application to the flash memory device. In response to a launch of the compressed application by an application launcher component, the preemptive decompression scheduler component determines from the stored metadata the one or more dependent objects associated with the compressed application to be launched. The preemptive decompression scheduler component preemptively schedules decompression of the one or more dependent objects based on the stored metadata.

Abstract: Systems and methods are disclosed for detecting high-level functionality of an application executing on a computing device. One method comprises storing, in a secure memory, an application-specific virtual address mapping table for an application. The application-specific virtual address mapping table comprises a plurality of virtual address offsets in the application binary code mapped to corresponding target application functionalities. In response to launching the application, a process-specific virtual address mapping table is generated for an instance of an application process to be executed. The process-specific virtual address mapping table defines actual virtual addresses corresponding to the target application functionalities using the virtual address offsets in the application-specific virtual address mapping table. During execution of the application code, the method detects when one or more of the actual virtual addresses corresponding to the target application functionalities are executed based on the process-specific virtual address mapping table.

Abstract: Systems, methods, and computer programs are disclosed for scheduling volatile memory maintenance events. One embodiment is a method comprising: a memory controller determining a time-of-service (ToS) window for executing a maintenance event for a volatile memory device coupled to the memory controller via a memory data interface; the memory controller providing a signal to each of a plurality of processors on a system on chip (SoC) for scheduling the maintenance event; each of the plurality of processors independently generating in response to the signal a corresponding schedule notification for the maintenance event; and the memory controller determining when to execute the maintenance event in response to receiving one or more of the schedule notifications generated by the plurality of processors and based on a processor priority scheme.
