  • Method and system for analyzing task group schedulability for hard real-time scheduling
    Patent number: 10296381
    Abstract: The method and system for analyzing schedulability configured for a computer for operating an operating system that supports a task group of hard real-time scheduling or a user processor operated in an embedded circuit. The system includes an operating system including a file system and a kernel, and generating non-periodic real-time task information and periodic real-time task information from the file system and the kernel, a tool for testing hard real-time schedulability that collecting the non-periodic real-time task information by applying a first predetermined scheduling algorithm and determining schedulability of a reserved resource for a real-time task group including the non-periodic real-time task information through a second predetermined scheduling algorithm.
