Abstract
An image processing device having a plurality of cores which attains more efficient memory access than conventionally attained. In the image processing device employing pipeline processing, a memory access section executes data transfer between an operation section including a plurality of cores each performing operation for image processing and an external memory . The memory access section has an access schedule storage portion which stores types of data transfers per stage, and executes data transfer between the operation section and the external memory in accordance with the storage contents of the access schedule storage portion . A system control section sets the types of data transfers in the access schedule storage portion at a stage preceding the stage at which the data transfers are executed. This makes it possible to change the types of data transfers with stages flexibly and thus allows the memory access section to execute only necessary data transfers at each stage without the necessity of arbitration.
