Abstract

The invention discloses a hardware decoding method and device based on the HEVC protocol. The device includes a processing module, a cache module, an AMBA bus and a decoding module; the decoding module includes an entropy decoding module, a decoding control module, a frame prediction module, and a frame processing module. module, a data reconstruction module, and a filtering processing module; the decoding control module is used to distribute the entropy-decoded code stream data to the frame prediction module and the frame processing module according to the operation command, and to send the code stream data in units of frames to store. When an error occurs in a certain frame of code stream data, the decoding control module can recover the buffered code stream data of the frame and transmit it again, thereby improving the security of video decoding, and thus has a broad market prospect in the field of integrated circuit design.

Description

technical field [0001] The present invention relates to the field of integrated circuit design, in particular to a hardware decoding method and device based on the HEVC protocol. Background technique [0002] With the development of science and technology and the progress of society, integrated circuit design has been widely used, and more and more electronic devices have entered people's daily life, which not only brings convenience to people's daily life, but also further promotes the development of science and technology. Innovation and R&D. In the field of integrated circuit design, video codec is one of the important items. [0003] High Efficiency Video Coding HEVC (High Efficiency Video Codec) is a next-generation international video coding standard currently being jointly developed by the International Telecommunication Organization (ITU) and the Moving Picture Experts Group (MPEG). Compared with the current international video standard H.264 / AVC, HEVC can reduce t...
