Abstract:
1. An image processing apparatus comprising: a first control unit that performs overall control of the image processing apparatus; a second control unit that is connected to the first control unit via a bus and that has an image processing function performing an image process for image data; and a storage unit that is connected to the second control unit and indirectly connected to the first control unit via the second control unit, and that stores the image data; wherein the first control unit comprises: a determination unit that determines, when an access request to access the storage unit is generated, whether the access request is a request for data transfer between the first control unit and the storage unit or a request for data transfer between the second control unit and the storage unit; and an access unit that, in a case where the determination unit has determined that the access request is a request for data transfer between the first control unit and the storage unit, accesses the storage unit in an order that the access request was generated, and that, in a case where the determination unit has determined that the access request is a request for data transfer between the second control unit and the storage unit, accesses the storage unit by prioritizing the access request irrespective of the order that the access request was generated; and wherein at least one of the first control unit and the second control unit comprises a computer processor.
