A multi-core processor device and a video decoding method using a multi-core processor, which can efficiently use system resources in a multi-core processor environment that requires a considerable amount of computation. The multi-core processor device includes a video decoder module which includes a plurality of function modules for performing video decoding; a memory which stores an input bitstream and loads the function modules; and a multi-core processor which includes a plurality of cores that perform a video decoding operation on the input bitstream by using the function modules, the cores including a first core and a second core, wherein, if the first core becomes idle during the video decoding operation, the second core allocates part of a remaining task of the second core to the first core and thus reduces an idle time of the first core.

Method and apparatus for video decoding based on a multi-core processor

Provided are a multimedia decoding method and multimedia decoding apparatus based on a multi-core platform including a central processor and a plurality of operation processors. The multimedia decoding method includes performing a queue generation operation on input multimedia data to generate queues of one or more operations of the multimedia data which are to be performed by the central processor and the operation processors, wherein the queue generation operation is performed by the central processor; performing motion compensation operations on partitioned data regions of the multimedia data by one or more motion compensation processors among the operation processors; and performing a deblocking operation on the multimedia data by a deblocking processor among the operation processors.
