The invention provides a probabilistic shaping coding device, a system and a method. The device comprises a plurality of data buffers, a data scheduling module and a probabilistic shaping coding module, the plurality of buffers are used for buffering input data blocks; the data scheduling module is used for determining a target buffer according to a set priority rule and scheduling data in the target buffer; and the probability shaping module is used for collecting a bit stream probability interval and a symbol probability interval according to the target cache, and performing probability shaping coding on the currently scheduled data according to the bit stream probability interval and the symbol probability interval. Input data is cached into a plurality of buffers, the data in each buffer is scheduled by a data scheduling module according to a set priority, and then the data is coded by a probabilistic shaping coding module, so that the input data can be simultaneously coded in parallel, the probabilistic
