Abstract

The invention discloses an information outputting method using coding / decoding, coding static information which needs outputting as a program runs and keeps constant in the running course of the program and making the coding unique; establishing a corresponding relation between code and static information; executing the program and receiving output information; using a code in the output information to inquire the corresponding relation so as to obtain corresponding static information and substituting the corresponding static information for the code in the output information and finally outputting the information.

Description

Technical field [0001] The present invention relates to coding and decoding technology in the fields of computers and communications, and in particular to a method for outputting information using coding and decoding. Background technique [0002] In the software code, in order to debug, track, test, understand the operating status of the system, and locate faults, it is often necessary to output some software operating information, such as printing information, debugging information, log information, trace information, and alarm information. For the convenience of reading, developers often use text to output this information. When the software performance requirements are not high, or the software scale is not large, the text method is a simple and effective method, and the impact on software performance is not very obvious. However, in embedded real-time environments or other commercial environments, it often has higher requirements for software performance, and the software sc...
