Abstract:
PURPOSE: An image restoration method copying a memory and a device thereof are provided to execute the interpolation of a current image by changing pixel data of a reference image based on block information of a current image. CONSTITUTION: When motion information included in block information is the same as a reference value, an image restoration device determines the application of a weighted value(401,402). When the application of the weighted value is determined, the image restoration device generates a prediction image based on the weighted value(406). When a current image mode is not a skip mode, the image restoration device generates a residual image based on change coefficient information(403,407). The image restoration device restores the current image by using the residual image and a prediction image(408).

PURPOSE: A memory access address converting device and method are provided to reduce overhead generated in the memory reference by storing continuing tiles among tiles comprises an input image in the different bank. CONSTITUTION: An address assigner(210) compartmentalizes pixels comprising an input image with a tile as a unit and assigns memory address to tiles. An address generation unit(220) creates new memory address for storing continuing tiles in the different bank by using the memory address. A tile reading unit reads the continuing tiles. A tile output unit outputs the tiles which are read. The tile reading unit reads nest tile saved in different bank while the tile output unit outputs a current tile among the continuing tiles. The tiles include pixel information of the pixels comprising the input image. A memory control unit(230) stores the tiles in the new memory address.

PURPOSE: A cache memory system and an operation method thereof are provided to reduce a cache miss, and increase the efficiency of memory traffic by selectively determining the volume of information fetched according to the state of information existed in a cache. CONSTITUTION: A large quantity of information which a center control unit(40) can refer is stored in a lower position memory element(48). The second auxiliary storage unit(44) fetches the determined volume of information including information referred from the center control unit(40) as the second information, and stores the information. The first auxiliary storage element(42) stores the first information fetched from the second information stored in the second auxiliary storage element(44) including the information referred by the center control unit(40) or the lower position memory element(48). A control unit(46) is composed of a state storage element(46a) and a demultiplexing unit(46b). The state storage element(46a) is included in the second information. The demultiplexing unit(46b) is controlled by the control unit(46).

An image searching method for motion estimation is provided to perform a decoding operation according to H.264 standard at a high speed by reducing a computing amount required for motion estimation. An image searching method for motion estimation includes: comparing an estimated minimum SAD(Sum of Absolute Difference) value with a threshold value(S510); determining a code of a motion vector(S520); calculating absolute values of gradients of base frames n and n-1(S530); judging whether both of an amplitude of a first gradient and an amplitude of a second gradient are 1(S540); judging whether the amplitude of the first gradient is less than 1(S550); extending a region in which a selective UMHGS search is performed in a horizontal direction(S555); judging whether the amplitude of the first gradient is greater than 1(S560); determining that the region in which a selective UMHGS search is performed is a uneven hexagon pattern(S570); performing UMHGS search inside the selected region(S580); comparing a newly obtained SAD value with the threshold value and judging whether a selective UMHGS search is terminated(S590).
