Abstract

The invention discloses a reusable pixel processing method and a reusable video processing chip. According to the method, a same pixel processing device is used for executing at least two types of pixel processing. The method includes: determining processing types for processing a current frame; configuring corresponding commands of the processing types in the pixel processing device; and performing processing of each execution cycle for to-be-coded macro blocks of the current frame sequentially by the aid of the configured commands corresponding to the determined processing types of the current frame. The video processing chip comprises a determining unit, an acquisition unit, a register array, a clock control unit, a controller and an arithmetic unit array. The reusable pixel processing method and the reusable video processing chip have the advantages that by the reusable design technology, registers and arithmetic units are configured by different methods, so that single hardware unit can be reused for multiple operations in a time division manner, computing and storage logic complexity of the chip is lowered, and the area and power consumption of the chip are reduced.

Description

technical field [0001] The invention relates to the field of multimedia processing, in particular to a reusable pixel processing method and a corresponding video processing chip. Background technique [0002] During video coding and image processing, motion estimation, video scaling, and spatial / temporal filtering are all important components. [0003] Motion Estimation is a technique widely used in video coding and video processing. The basic idea is: in video inter-frame predictive coding, based on the correlation between the scenes in the adjacent frames of the moving image, each frame of the image sequence is divided into many non-overlapping macroblocks, and all pixels in the macroblock are considered The displacements are the same, and then find the most similar block to the current block (that is, the matching block) according to a certain matching criterion within a given search range from each macroblock to the reference frame, and the relative displacement between...
