    摘要: Provided are an apparatus and method for recognizing an image. In the apparatus and method for recognizing an image, various features can be extracted by a Haar-like filter using 1st to nth order gradients of the x- and y-axis of an input image, and the input image is correctly classified as a true or false image using, in stages, the extracted features of the input image, multiple threshold values for a true image and multiple threshold values for a false image. Accordingly, the apparatus and method achieve a high recognition rate by performing a small amount of computation. Consequently, it is possible to rapidly and correctly recognize an image, enabling real-time image recognition.

    摘要: Provided is a parallel processor for supporting a floating-point operation. The parallel processor has a flexible structure for easy development of a parallel algorithm involving multimedia computing, requires low hardware cost, and consumes low power. To support floating-point operations, the parallel processor uses floating-point accumulators and a flag for floating-point multiplication. Using the parallel processor, it is possible to process a geometric transformation operation in a 3-dimensional (3D) graphics process at low cost. Also, the cost of a bus width for instructions can be minimized by a partitioned Single-Instruction Multiple-Data (SIMD) method and a method of conditionally executing instructions.
