Problems solved by technology

[0003] The CABAC arithmetic decoding method will save code streams and correspondingly save data storage space, but the hardware implementation process of the entire decoding process of traditional CABAC arithmetic decoding is complicated, and the calculation is performed in binary bit order, and the serialization requirements are high, resulting in increased computational complexity.
At the same time, when decoding high-definition streams, the task of real-time decoding cannot be completed

Abstract

The application discloses an entropy decoding method and device, and electronic equipment. The method includes: reading in binary code stream data to obtain decoding parameters, and performing binary arithmetic decoding and renormalization on the binary code stream data in parallel according to the decoding parameters. In this application, by adjusting and adding some variables and calculation methods, the decoding and renormalization are changed from serial calculations to parallel calculations, which saves the time required for hardware and facilitates the implementation of hardware pipelines.

Description

technical field [0001] The present application relates to the technical field of video encoding and decoding, and in particular to an entropy encoding method and device, and electronic equipment. Background technique [0002] With the improvement of display resolution, the processing of data in the display industry is becoming more and more important. Compression and decompression have become important data processing methods, but there are certain disadvantages to the current traditional decoding methods. H.264, also known as MPEG-4AVC (Advanced Video Coding, Advanced Video Coding), is a video compression standard and a widely used high-precision video recording, compression and distribution format. Traditional H.264 has two entropy coding schemes, corresponding to two decoding methods: one is the context-based adaptive variable length coding CAVLC developed from the variable length coding scheme; the other is developed from the arithmetic coding The context-based adaptive...
