System and method for verifying video coding method

Abstract

The invention discloses a system for verifying a video coding method, which comprises a video coding reference model module (204), an algorithm control module (205), a video coding module (206) and a result comparison module (208), wherein the algorithm control module (205) controls the video coding module (206) and the video coding reference model module (204) to output algorithm step parameters by steps; and the result comparison module (208) compares the parameters by steps. The scheme monitors the algorithm by steps, compares and judges by steps, judges each step result in real time and is convenient to debug.

Description

technical field [0001] The invention relates to the technical field of video coding, in particular to a system and method for verifying a video coding method. Background technique [0002] In digital chip design, the verification of logic functions is more and more important. Ensuring the correctness of the logic function design, the accuracy of the algorithm meets the requirements, and the efficient function verification and function debugging are the key links in the digital chip design, and even relate to the progress of the entire project. [0003] At present, the logic function verification method widely used in video codec design is simulation verification method. The video encoding method includes motion vector search, residual calculation, discrete cosine transform (DCT) operation, quantization and encoding. figure 1 Shown is a system block diagram for performing simulation verification on video encoding data in the prior art. A video data segment 101 is intercept...
