A method for dynamically arranging interrupt pins is provided, which is suitable for arranging a plurality of interrupt pins of a control chip. In this method, a number of interrupts sent from each of a plurality of device paths in a unit time is detected. The device paths are sorted according to the interrupt numbers thereof. Then, from the one in the head of the sequence, the devices paths are arranged to the interrupt pins. Herein, when arranging a device path, an interrupt checking number required to check the device path sending the interrupt every time an interrupt is produced in each of the interrupt pins is calculated. Then, when arranging the next device path, the device path is arranged to the interrupt pin with the least interrupt checking number.
