Device and Method for Schedulability Verification of Security Reinforcement Techniques in Real time Devices

摘要

The present invention provides a basic task allocator for allocating at least one basic task with a set deadline to the processor, an additional task having the highest priority compared to each of the allocated basic tasks, and adding an additional task to which a security enhancement technology is applied before each basic task is performed An additional task allocating unit for allocating to the processor to be performed, a task performing unit for performing a task according to the priority of the assigned basic task and each additional task, Corresponding to the least common multiple of the periods of the basic task from the process in which the task is performed Including a deadline determining unit that calculates the time point to be performed in real time and determines whether the deadline of the basic task is met based on this, variously changing and applying independent security enhancement technology in a real-time device environment, while dynamically changing its scheduleability has a verifiable effect.
