Abstract

Pre-fetching instructions for tasks of an operating system (OS) is provided by calling a task scheduler that determines a load start time for a set of instructions for a particular task corresponding to a task switch condition. The OS calls, and in response to the load start time, a loader entity module that generates a pre-fetch request that loads the set of instructions for the particular task from a non-volatile memory circuit into a random access memory circuit. The OS calls the task scheduler to switch to the particular task.
