A method of controlling multi-bus using interrupt mode includes a first step of generating an interrupt signal according to main processing of a first processor 100 to allow the first processor 100 to recovery the bus use and to return to the main processing, a second step of judging the interrupt signal generated by the first processor 100 by main processing of a second processor 200 and, when the second processor 200 recognizes the interrupt signal, outputting a signal indicating the bus use request to thereby judge if a bus use approval signal is applied, and a third step of using the bus, outputting a bus use completion signal, returning to the main processing, and generating a second interrupt signal, thereby recovering the bus use of the first processor. |
