  • User space pre-emptive real-time scheduler
    Patent number: 10983846
    Abstract: A computer implemented method includes executing a user space partition first real-time task from a real-time task queue on a real-time kernel thread executing on a computing core of a computer, wherein the real-time kernel thread is scheduled by an operating system scheduler, pre-empting the first real-time task via a user space partition real-time task scheduler in response to a task switch signal, saving a first real-time task context, loading a user space second real-time task context for use by the real-time kernel thread via the user space partition real-time task scheduler, and executing the second real-time task from the real-time task queue on the real-time kernel thread.
