MOTION ESTIMATION DEVICE AND METHOD SUITABLE HARDWARE IMPLEMENTATION

摘要

The present invention relates to a motion estimation apparatus and a method suitable for hardware implementations, especially video data bus ( 1) the rough current frame buffer to store the current image data (100); Video data bus (1) the rough reference frame cache that stores the image data 200; A frame cache (200) for storing a reference frame rough reference image data buffer 300; Current frame buffer 300 of the current image data and the reference frame buffer 300 of the reference image by comparing the data for calculating a plurality of difference absolute values at the same time, the parallel processor 400; The Candidate and best characterized by consisting of the X-axis or Y-axis directional movement in the rectangular search pattern in consideration of the DMA controller to perform the prediction direction 500, the motion vector, the present invention is the miniaturization of the video encoder of the portable nature of chip system low-power screen, SD RAM and by ensuring effective operation and simple hardware implementation of this possible, from the portable device allows you to implement the MPEG-1,2,4, or follow the H.261,263,264 standard video encoder has an outstanding effect.
