METHOD OF CONFIGURING KERNEL FOR REAL-TIME THREAD PROCCSING OF GENERAL PURPOSE OPERATING SYSTEM

摘要

PURPOSE: A kernel configuration method for real-time thread processing in a general purpose operating system is provided to use a real-time extended kernel, which is separately implemented, using timer interrupt for generating and handling real-time thread processing, thereby implementing an independent scheduling of the real-time extended kernel not depending on a scheduling of the general purpose operating system. CONSTITUTION: A kernel configuration method for processing a thread in real time comprises the steps of: increasing the priority of the thread for processing the thread in real time (S100); generating an interrupt to the tread having increased priority through an interrupt generator that is configured to operate independently from a timer of a general purpose operating system (S200); delivering the generated interrupt to an interrupt service routine (ISR) using a preset interrupt descriptor table (IDT) (S300); and calling a kernel function and processing the interrupt using the kernel function by the ISR (S400).
