An application processor includes a system memory unit, peripheral devices, a control unit and a central processing unit (CPU). The system memory unit includes one page table. The peripheral devices share the page table and perform a DMA (Direct Memory Access) operation on the system memory unit using the page table, where each of the peripheral devices includes a memory management unit having a translation lookaside buffer. The control unit divides a total virtual address space corresponding to the page table into sub virtual address spaces, assigns the sub virtual address spaces to the peripheral devices, respectively, allocates and releases a DMA buffer in the system memory unit, and updates the page table, where at least two of the sub virtual address spaces have different sizes from each other. The CPU controls the peripheral devices and the control unit. The application processor reduces memory consumption.
