ABSTRACT:
The imaging apparatus includes a plurality of image processing circuits, a memory having real address space, a memory management unit that performs virtual memory control, and a CPU that controls the image processing circuits. Each image processing circuit has a function of specified data processing, and writes/reads data to/from the memory in virtual address space. The memory management unit has corresponding information for managing correspondence between specified data unit region (virtual page) in virtual address space, and specified data unit region (real page) in real address space, and deletes the correspondence between virtual page and real page concerning the read data in the corresponding information when the image processing circuit completes the read operation of the data in specified data unit from the memory.
