This paper's research content are mainly in the following
aspects:
• Discuss the characteristics of the embedded system and
complete the transplantation and cutting of embedded
Linux operating system;
• Discuss the basic principle and characteristics of GPRS
and related AT instruction set ;
• On the function demand of system analysis and design,
the entire system realizing is divided into PC interface
control module, PC end network communication
control module, ARM end network communication
control module, GPRS communication control module
several function module to realized respectively˗
• Construct the development of embedded Linux
environment, including the establishment of cross
development environment, the ARM platform
embedded Linux system transplantation;
• Realize the embedded Linux GPRS communication
system modules based on ARM development platform,
each function module one by one;
• Complete each module combination and testing system
function, summary analysis system realization
condition.
