Abstract

The invention discloses a transform coding system and method, which is applied to video coding and decoding. The system includes: an input transform module, a judgment module and an output module; wherein the judgment module is respectively connected with the input transform module and the output module. connection; wherein, the input transformation module includes a plurality of first buffers (rams) and a plurality of second buffers (rams), and the plurality of first buffers (rams) are used to buffer the one-dimensional DCT transformation results in the X direction; The plurality of second buffers (rams) are used for buffering the one-dimensional IDCT transform result in the Y direction. Therefore, according to the embodiment of the present application, since the input transformation module uses multiple first buffers (rams) and multiple second buffers (rams) for buffering transformation results, the chip size of the video encoder is reduced.

Description

technical field [0001] The invention relates to the technical field of video encoder chip implementation, in particular to a transformation coding system and method. Background technique [0002] In recent years, with the popularity of high-definition and ultra-high-definition video, the amount of original video data has increased sharply, which has brought huge pressure on storage and transmission. How to further improve the compression efficiency of video coding is a crucial issue. When compressing efficiency, the first thing to consider is how to efficiently encode the pixel blocks in the video. [0003] In the current traditional implementation of encoding pixel blocks in video, four independent encoding modules are used to encode pixel blocks in video, one for each luminance block of a 32-dot x 32-dot 1024-dot pixel image. Encoding module is realized, the luminance block of a 16-point x 16-point 256-pixel image is realized by one coding module, the chrominance block of...
