<p>Provided is a decoding device which can perform video decoding in a real time with a sophisticated video specification requiring a frequent access to an external memory. A video decoding device (100) includes a hardware video decoder (115) which executes decoding of a pixel coefficient and write of a reconfigured picture into an external memory (110). A hardware video decoder (115) includes: a hardware engine pipeline (201) formed by a plurality of hardware engines requiring a DMA read access or a DMA write access to the external memory (110) or both of the accesses; and a hardware video decoder DMA controller (200) which adjusts all the DMA accesses from the hardware engines to one DMA channel or a plurality of DMA channels to a DMA controller (111).</p>
