Abstract: Provided are an interrupt on/off management apparatus and method for a multi-core processor having a plurality of central processing unit (CPU) cores. The interrupt on/off management apparatus manages the multi-core processor such that at least one of two or more CPU cores included in a target CPU set can execute an urgent interrupt. For example, the interrupt on/off management apparatus controls the movement of each CPU core from a critical section to a non-critical section such that at least one of the CPU cores is located in the non-critical section. The critical section may include an interrupt-disabled section or a kernel non-preemptible section, and the non-critical section may include an interrupt-enabled section or include both of the interrupt-enabled section and a kernel preemptible section.
