Intra-frame predicting circuit for video coder and realizing method thereof

Abstract

The invention discloses a realizing method of an intra-frame predicting circuit for a video coder. The method comprises the following steps of: mapping all functions of an intra-frame predicting circuit of a video coder described by a high-level program language algorithm into hardware logic description formed by operator units; and generating a hardware integrated circuit of the intra-frame predicting circuit by the hardware logic description formed by the operator units. By applying the invention, a system engineer can design the hardware integrated circuit of the intra-frame predicting circuit at higher speed by designing the operator units for expressing hardware logics on the premise of ensuring that a digital high-definition video code is not damaged according to a complete operatorunit library which is sufficient to support and describe a high-level language algorithm. Moreover, the intra-frame predicting circuit can also carry out parallel flowing operation with ASIC (Application Specific Integrated Circuit) parts of other special integrated circuits in a video coder and improves the design speed of ASIC of the video coder.

Description

technical field [0001] The present invention relates to digital video processing technology, in particular to an intra-frame prediction circuit for a video encoder and its implementation 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 the...
