Problems solved by technology

[0009] In order to solve the problem that each frame of image in the traditional memory access design must be read twice from off-chip storage, the first purpose of the present invention is to provide a method for reusing data between frames for motion estimation, which uses adjacent Data reuse between frame images can reduce the number of memory accesses and improve video processing speed

Abstract

The invention discloses a motion estimation-oriented inter-frame data reuse method and device. The method for reusing data between frames for motion estimation includes: processing at least two current frames in turn in the same time period, and using the same starting point and scanning order; when processing any two adjacent frames, processing the current frame The resulting data is read to the on-chip cache in time for direct reading when processing adjacent frames, realizing the reuse of inter-frame data of the current frame; in this way, when m current frames are processed in the same time period, only 1 / m The frame is read twice, and the remaining frames only need to be read once; where m≥2 and m is a positive integer.

Description

technical field [0001] The invention belongs to the field of data processing, and in particular relates to a motion estimation-oriented inter-frame data reuse method and device. Background technique [0002] The frame rate boost is used to optimize the display effect of dynamic images on LCD TVs. The frame rate improvement technology mainly solves the problems of significant decrease in motion resolution and motion blur smearing caused by the response delay of the LCD panel by increasing the refresh rate of the TV video image. The frame rate improvement is achieved by inserting one or more frames of images between two frames of images before and after, and the frame interpolation method based on motion estimation is one of the most effective methods. [0003] However, the accuracy of motion estimation has an impact on the quality of interpolated frames. Motion estimation is usually the most computationally and memory-intensive part of frame rate boosting, often accounting ...
