| With the constructed and development of some dedication telephone communications system. More than voice communicatione,user bring forward more and higher requirement about telephone bear the weight of data traffic operation.In this thesis,it is maily about design and realize of data transmission communications software of the embedded operating system based on ARM11.It is mainly discussed and resolved how to design the data transmission communication software based on embedded operating system.Different to tradition system,this project import embedded operating system,so,this software can be used beyond computer to transmit data.This software will be used in Linux,,then the main results are as follows:1. The study about embedded system.2. The study about the design of whole equipment of embedded data transmission communication.3. Scheme out the data transmission communication system software.4. Debugging and relize about the software.In this thesis,the data transmission communication software is based on embedded system. It can be used without computer.In this way,the dedication telephone communications system can be used in widen range.With the development of this system,the software will play more important role. |
