Embodiment Construction

[0040] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0041] 1. Overview of Video Encoder

[0042] Video coding technology is a key technology for digital media storage and transmission, and it is widely used in digital TV, video communication, network streaming media and other fields. The invention relates to an entropy encoder for a video encoder based on an operator idea and a realization method thereof, which is suitable for entropy encoding of various image / video / audio DCT transformation data in the field of signal processing.

[0043]Currently in the field of video coding, the new digital video coding standard - H.264 jointly formulated by the Joint Video Team (JVT) jointly established by the International Telecommunications Union (ITU-T) and the International Organization for Standardization (ISO) has been widely used. The H.264 algorithm is not only H.264 of the Internationa...

Abstract

The invention discloses an entropy coder for a video coder and an implementation method thereof. The implementation method of the entropy coder comprises the following steps: mapping each coding functional block of the entropy coder of the video coder into hardware logic description which is composed of operator units, wherein each coding functional block is described by an advanced program language algorithm; and generating a hardware integrated circuit of the entropy coder by the hardware logic description which is composed of the operator units. According to the invention, the design speed for the integrated circuit of the entropy coder can be quickened.

Description

technical field [0001] The invention relates to an entropy coder for a video coder and its realization method. Background technique [0002] Integrated circuit design methodology is a methodology used to guide integrated circuit design. The current integrated circuit design, especially the large-scale integrated circuit design, its common design process is: the system engineer proposes the system function framework according to the functional requirements, and the software engineer uses the computer advanced programming language (such as: Java, C, C++, Matlab, etc.) Describe the functional framework of the system to obtain the algorithm description of the high-level programming language of the integrated circuit; then the integrated circuit design engineer uses the hardware description language (such as: Verilog, VHDL, etc.) to synthesize the algorithm description into a netlist file, and then uses a special The hardware synthesis tool realizes layout and routing, and obtai...
