PURPOSE: A method for performing IPC(Inter Processor Communication) using a dual port RAM in a CDMA system is provided to combine benefits of an existing interrupt system with benefits of a polling system during the IPC, and to perform DPRAM communication, thereby preventing IPC interruption by preventing interrupt loss. CONSTITUTION: The first processor(100) generates an interrupt while setting a flag to an 'interrupt generation' state. If the first processor(100) wants to re-generate the interrupt, the first processor(100) checks the flag and re-generates the interrupt only when the flag is set to a 'processing completion' state. The second processor(200) sets the flag to the 'processing completion' state after completing the processing of all interrupts, so that the first processor(100) generates the interrupt.
