1. A method for generating an interrupt signal in a multi-processor comprising a plurality of cores, the method comprising: accessing a memory address; determining, by a Modified Memory Unit (MMPU), a memory region that corresponds to the accessed memory address, when the access to the memory address has occurred; determining, by the MMPU, a core, among the plurality of cores, that corresponds to the determined memory region; and transmitting, by the MMPU, the interrupt signal to the corresponding core according to the memory access.
