Abstract
A decoding device comprises a cache memory for temporally storing video image data, a unit for determining a position of a reference macroblock corresponding to macroblock to be decoded based on a motion vector obtained by analyzing an encoded bitstream, and a unit for determining whether or not a reference macroblock includes a cacheline boundary when data of the reference macroblock is not stored in the memory and for specifying the position of the boundary as a front address for the data preload from a memory storing the data of the reference macroblock.
