A method and apparatus for processing data in a heterogeneous multi-core environment, capable of reducing data processing time by storing frames not having redundant data only among input frames in a shared memory. The apparatus compares a second frame with a first frame having a time difference with respect to a first frame, thereby determining identity between the first frame and the second frame. The apparatus stores address information related to the first frame or stores the second frame according to the determination result, thereby reducing quantity of data to be updated.
