  • Patent number: 10783979
    Abstract: A built-in self-test (BIST) circuit and a method of operating BIST circuit is disclosed. The BIST circuit is configured to generate a test pattern based on a plurality of test parameters including a first test parameter and a second test parameter and perform a test on at least one memory core. The method includes setting a sweep range comprising a sweep start point of the first test parameter and a sweep end point thereof; generating a first test pattern corresponding to each sweep point of the sweep range from the sweep start point of the first test parameter and the sweep end point thereof and providing the first test pattern to the at least one memory core; receiving output data corresponding to the first test pattern from the at least one memory core and comparing the output data and a predetermined reference data; and generating first test result information based on results of the comparing.

  • Patent number: 9786063
    Abstract: Provided is a method of computing precise disparity using a stereo matching method based on developed census transform with an adaptive support weight method in area based stereo matching. The method includes a step of setting an adaptive support weight window centered on a specific point of a left image and setting adaptive support weight windows with the same size with respect to one point positioned within a maximum disparity prediction value about a specific point of the left image in a right image.

  • Patent number: 9014463
    Abstract: A system for real-time stereo matching is provided, which provides improved stereo matching speed and rate by gradually optimizing a disparity range used in the stereo matching based on the stereo matching result of the previous frame image and thus reducing unnecessary matching computations.
