Problems solved by technology

[0004] The MD implementation scheme in the video coding standard reference software is obviously not suitable for hardware encoders. At the same time, although there are some MD hardware circuits for the HEVC standard, considering the different goals and factors such as coding tools, performance, and main frequency, the involved schemes and Background doesn't work directly with AVS3 hardware encoders

Abstract

The invention discloses an AVS3 mode decision circuit structure, a mode decision method and electronic equipment. The circuit structure comprises an a-order processing circuit and a comparison circuit, wherein a is a non-negative integer, the a-order processing circuit is used for directly processing the maximum coding unit with the size of (2an) * (2an) under AVS3 to obtain at least one rate distortion optimization value, the size of the basic coding unit is n * n, and n is a positive integer; the comparison circuit is used for comparing the at least one rate-distortion optimization value and determining the rate-distortion optimization value with the minimum cost value and the mode corresponding to the rate-distortion optimization value with the minimum cost value. The mode decision processing circuit is designed for circuits of different sizes, the circuits of different sizes are subjected to parallel and serial processing of different degrees, the processing time and data characteristics of each size are fully considered, the circuit and storage area is saved, the circuit size and the processing speed are considered, and the requirements on the two in practical application can be well met.

Description

technical field [0001] The present application relates to the technical field of video processing, in particular to an AVS3 mode decision-making circuit structure, mode decision-making method and electronic equipment. Background technique [0002] In the video coding standard, many coding mode divisions are generally supported, including CU (Coding Unit, coding unit), PU (Prediction Unit, prediction unit) and so on. For example, standard standards such as AVS2 and HEVC support CU / PU sizes ranging from 4x4, 8x8, 16x16, 32x32, and 64x64, including corresponding non-square divisions. In particular, in addition to the quadtree division mode in AVS2, more division modes have been introduced in the latest AVS3 video coding standard, including binary tree division and extended quadtree division modes. In order to obtain the final optimal division mode among many division modes of each size, an MD (Mode Decision, mode decision) module is introduced. This module is generally the co...
