Provided is a dynamic Huffman encoding method based on a sorting network. Compared with traditional dynamic Huffman coding solutions, the method implements sorting on the basis of the sorting network, therefore the sorting process is not only stable, but also may ensure a stable sorting result; and moreover, sorting steps and related operations are simpler, thereby greatly simplifying the sorting and iteration processes, and thus the sorting efficiency is higher. In addition, the sorting process better facilitates program implementation and transplantation, and implementation of hardware and software may achieve good effects. In addition, the present disclosure further provides a dynamic Huffman coding apparatus and device based on a sorting network, and a readable storage medium, and the technical effects thereof correspond to the technical effects of the above method.

A signal name based method for automatic signal exchange between multiple embedded CPU boards, includes: dividing CPU boards into master board and slave board, where each slave board sends signal registration information to the master board; reading an exchange relationship between an output signal and an input signal that is represented by a connection line between signal names, calculating and allocating a data bus address to which the output signal and the input signal are mapped, and sending memory addresses, data types, and bus addresses of signals to each slave board; saving these as output signal tables and input signal tables; and writing, by a signal sender, a value of an output signal into a corresponding bus address according to the output signal tables, and reading, by a receiver, a value of an input signal from a corresponding bus address according to the input signal tables.
