Embodiment Construction

[0059] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0060] 1. Overview of Video Encoder

[0061] 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 inter-frame predictor based on an operator idea and a realization method thereof, which is suitable for inter-frame prediction of various image / video / audio DCT transformation data in the field of signal processing.

[0062] At present, 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 International Telec...

Abstract

The invention discloses a method for implementing an inter-frame predictor for a video encoder. The method comprises the following steps of: mapping each functional block of the inter-frame predictor of the video encoder which is described by a high-level program language algorithm into hardware logic description consisting of arithmetic operator units; and generating a hardware integrated circuit of the inter-frame predictor by the hardware logic description consisting of the arithmetic operator units. By the method, the speed for implementing the integrated circuit of the inter-frame predictor can be increased. The invention also discloses the inter-frame predictor acquired by the method.

Description

technical field [0001] The invention relates to an inter-frame predictor for a video encoder 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,...
