摘要: A motion estimator and an estimation method for a video encoder to reduce power consumption by reducing the computational complexity of the motion estimator. In an upper step, a full search for a ±4 pixel search region for a 4×4 pixel block is performed at ¼ video resolution, to detect two motion vector candidates. In a medium step, a partial search for two vector candidates selected in the upper step and one vector candidate using a spatial correlation is performed for a 8×8 block within a ±1 or ±2 search region, to decide one motion vector candidate. In a lower step, a partial search for the ±1 or ±2 search region on 16×16 block is performed at full resolution, and a half pixel search for a motion vector candidate obtained in the lower step is performed to estimate a final motion vector. A ±4 pixel search region is operatively divided into four search regions, and the estimator sequentially searches the four ±2 pixel search regions to sequentially output SAD values.

摘要: According to a coefficient variable length coding method adopting four-stage pipeline, a 3-dimension value including a run, a level and a last data is obtained by performing a run length coding upon coefficient data, where, after transferring the 3-dimension value, a variable bit vector is obtained from the transferred 3-dimension value and the variable length bit vector is stored, and where, particularly in case the pipeline breaks, the method reuses the previously obtained 3-dimension value to minimize process time such that the coefficient variable length coding is swiftly performed by the efficient pipeline operation, and the broken pipeline may be restored within minimized time.
