description The invention discloses a video coder and a coding method, which belongs to the field of video coding. The coder is divided into five-stage flow modules comprising a data loading module, a first storage module, a whole pixel movement estimation module, a second storage module, a sub-pixel movement estimation module, a third storage module, an integrative processing module, a fourth storage module, a loop circuit filtering module and an entropy coding module. The invention also provides the video coding method. Data interaction between the five-stage flow modules is carried out by utilizing a dual-port memory module, the control logic of the data interaction is simplified, and the speed of data transmission between flow stages is enhanced. In the video coder, the data interaction between the stages is carried out in macroblock stages, data structures are consistent, the control procedure is simplified, the throughput rate is effectively enhanced, the delay is lowered, and real-time coding can be carried out on
