Patent

CA 2139972

The present invention relates to a data converting device for converting data by employing a plurality of LUTs stored in a single memory device a data converting device for generating, with reference to two or more LUTs sequentially, a converted output data corresponding to input data and converting level selected by each LUT, the data converting device comprises a single memory device for storing two or more LUTs corresponding to the number of data converting modes by block units, each block including a plurality of sub-LUTs corresponding to the number of converting levels defined in each corresponding converting mode; and an address generator for generating an address for accessing the memory device by an input data, the data selected among the output data read from the memory device and the data for selecting converting level in each converting mode, the address being generated repeatedly as many times as correspond to the number of LUTs stored in the memory device, to thereby minimize the bulk of the memory device, and thus enabling the miniaturization of the data converting device.
