<P>PROBLEM TO BE SOLVED: To facilitate to secure a large capacity of a continuous memory space for handling a large capacity of image data, or the like in an image forming apparatus. <P>SOLUTION: In a conventional virtual memory system, it is difficult to obtain a large capacity of continuous memory due to fragmentation, or the like which is caused by capacity restriction of a memory to be obtained and memory acquisition/release operation in OS management because an OS manages a memory space. However, an OS non-management memory area managing part is provided, which divides a physical memory space into an OS management area and an OS non-management area, allocates them to a virtual address space, and enables an application program to access the OS non-management area. <P>COPYRIGHT: (C)2010,JPO&INPIT |
