Decoding system and method

Abstract

Embodiments of decoding systems and methods are disclosed. One system embodiment, among others, comprises a software programmable core processing unit having a context-adaptive binary arithmetic (CABAC) unit configured to execute a shader, the shader configured to implement CABAC decoding of a video stream and provide a decoded data output.

Description

technical field [0001] The present invention relates to a decoding system and a decoding method thereof, in particular to a decoding system and a decoding method of a content-adaptive binary arithmetic coding applied to a computing core in a programmable graphic processing unit. Background technique [0002] Computer graphics is an art and science for computers to generate images, videos or other graphics or image information. The current graphics system mostly includes several interfaces, such as Microsoft's Direct3D interface and OpenGL, etc., so that it can be used to execute specific operating systems ( Computers such as Microsoft Windows) control multimedia hardware such as graphics accelerators or graphics processing units (graphics processing units, GPUs). The generation of images and images is often referred to as "rendering". The details of such operations It is generally performed by a graphics accelerator. In three-dimensional (3D) computer graphics, the geometric...

Problems solved by technology

[0003] Computer graphics must meet consumers' requirements for controllability and features of games and other multimedia products, as well as produce more realistic images and improve processing speed and power consumption. Many standards have been developed to utilize less bits. For example, the H.264 standard (also known as the tenth part of the ISO Animation Experts Group MPEG-4) is a high-compression digital video coding standard. Compared with MPEG-2 compatible coding, H.264 .264 compatible encoding only needs about one-third of the number of bits to store video with the same video quality. -adaptive binary arithmetic coding, CABAC) and context-adaptive variable length coding (CAVLC), about CABAC, its decoding operations are usually processed sequentially, requiring a lot of calculations to get range, compensation, content (context ) information and other parameters, the current CABAC decoding structure can meet some of the needs of consumers, but there are still limitations in the design
