Abstract

The invention relates to an image coding method and equipment based on a multi-core processor. The method comprises the following steps of selecting a plurality of preset coding modes; coding image macro blocks to be coded in parallel by the multi-core processor according to the preset coding modes, wherein the multi-core processor comprises a plurality of digital signal processing chips; and selecting one preset coding mode as a final coding mode of the image macro blocks to be coded according to a coding result. Compared with an existing method, the image macro blocks to be coded are coded in parallel by the multi-core processing equipment, the processing speed is high, the efficiency is high, and the video image coding compression efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of compression, in particular to an image coding method and device based on a multi-core processor. Background technique [0002] With the gradual development and rapid promotion of multimedia communication technology and multimedia communication application business, a series of video image compression coding standard technologies have received extensive attention. In the future, people's demand for the transmission and storage of high-definition video images will show explosive growth. However, the development of information network infrastructure such as the Internet, communication networks, and broadcasting networks is relatively lagging behind, and network bandwidth is still a bottleneck. Based on this fact, the next-generation video coding standard will focus on high-definition and ultra-high-definition video, and greatly improve the efficiency of video image coding and compression, so as to alleviate ...
