Processing method and device for state control protocol based on ARM architecture

An embodiment of the invention discloses a processing method and a processing device for a state control protocol based on an ARM architecture. The method comprises the steps that: a sender adds keywords in original valid data; the valid data comprising the keywords is packed, and the packed valid data is obtained; the packed valid data is sent to a receiver; and the receiver extracts valid data from the packed valid data to obtain the original valid data. The processing method and the processing device add the plurality of keywords into a communication data stream, supports variable length of data, separate encoding and decoding of protocols at a software layer, greatly increases extensibility, shield a physical layer for protocol transmission, can be applied to different embedded platforms and different hardware interface, achieve the consistency of later protocols, solve the problems of difficult status synchronization, small communication data volume, hardware firmware upgrading and the like, improve main
