METHOD AND APPARATUS FOR INTERRUPT ALLOCATION OF MULTI-CORE SYSTEM

摘要

PURPOSE: An interrupt allocating method of a multi core system and a device thereof are provided to efficiently and quickly process interrupt by transmitting a signal for changing a corresponding interrupt control register into an interrupt processing impossible state to the interrupt control register. CONSTITUTION: An interrupt control register unit(110) records the interrupt processing performance of each core(130). When interrupt is received, an interrupt allocating unit(120) confirms the interrupt control register unit and allocates the interrupt to a core processing the interrupt. When the interrupt is allocated, the core transmits a signal for changing a corresponding interrupt control register into an interrupt processing impossible state to the interrupt control register unit and processes the interrupt. The core transmits the signal for changing the interrupt control register into the interrupt processing impossible state to the interrupt control register unit after the completion of interrupt processing.
