Research Of Embeded Linux OS Based On Smartphone

In this thesis,I mainly study how to constitute the Smartphone OS. At present,the embeded developerment has becomes more and more popularity.And this developerment increases rapidly by reason of it's sounce code's open, stability and security.In my paper,I analyze the modification of Linux kernel for several aspects.It includes the management of process,the management of memory and the selection of the file system.For Process,I explain the theory of Hard Rtlinux and Soft Rtlinux.For the memory,its primary content is how to modify the Dummy Memory.At the same time,I choose a mini file system which adapt to the embeded system.By the way,I analyze and modify the protocol of the TCP/IP.Next,I design a experiment.In this experiment,a embedded environment has been founded.Base on it,we can debug and run embedded programs. Last,A Embeded Linux OS is realized,which can run some simple programs.
