摘要： Provided are a method, apparatus, and medium for controlling direct memory access (DMA). The apparatus includes a memory which is divided into a plurality of storage areas, a memory controller which is connected to the memory and comprises a plurality of ports, a plurality of DMA controllers which independently control access to data stored in each of the plurality of storage areas, and a plurality of buses which connect the memory controller and each of the plurality of DMA controllers. Using the apparatus, the time required in accessing the data can be remarkably reduced by employing the plurality of DMA controllers in order to perform parallel access to the data stored in each area of the memory.

摘要： Provided are a method and apparatus for buffering image data for motion compensation. One of two buffers of a double register array buffer, i.e., a first buffer, is selected as a buffer in which data corresponding to a row of a block of an image is to be written and the other of the double register array buffer is selected as a buffer from which data corresponding to another row of the block is to be read, thereby speeding up motion compensation processing when compared with the use of a single register array buffer.

摘要： Restoring an image is achieved by restoring a block by executing at least one first restoring function and at least one second restoring function. The first restoring function may be implemented using software, and the second restoring function may be implemented using hardware. By assigning restoring functions to be either first restoring functions or second restoring functions, even an image having high resolution can be restored and reproduced in real-time.
