According to an embodiment of the present invention, an access control method of a dual port memory system comprises the following steps: requesting an access from a first processor to a dual port memory; and transmitting a result signal according to the access request from the dual port memory to the first processor. The result signal includes: a first result signal notifying success of an access; a second result signal notifying failure of an access; and a third result signal notifying hold of an access. Therefore, an optimized control is possible while significantly reducing an access retrial time since an access retrial process due to an application can be omitted. |
