Abstract


With the development of the Internet and the post-PC era , embedded systems become the focus of one of the IT industry has a huge market demand . Internet network of embedded devices become an important network development direction and the inevitable result . Embedded Linux source open , easy to transplant , to become the most promising development in the field of embedded embedded operating system , uClinux is designed for non - MMU microprocessors to build an embedded Linux operating system , the main advantages of the standard Linux stability , excellent network function and rich API. The study based on the the uClinux embedded system design and implementation with the theoretical and practical significance . Firstly, in - depth analysis of the key technologies in the uClinux embedded system , including the kernel composition , memory management , multi-process management , executable file format , and combined with the standard Linux compare the similarities and differences of these key technologies , in particular, the biggest change memory management focus on comparison . Hardware selection is essential in embedded systems , it affects the choice of embedded operating systems . This selection of Samsung S3C4510B microprocessor build hardware platform , the analysis of the ARM7TDMI architecture features and S3C4510B the function module discusses selected peripheral circuits , based on the design of the entire development board . Then Bootloader architecture , operating mode , and workflow and kernel boot process , and from the the kernel porting , and Bootloader transplant two aspects analyzed uClinux porting process . Followed by analysis and design of a lightweight Bootloader program , this program memory footprint can compiled uClinux kernel be easily ported to the target board . On the basis of the foregoing analysis and research , the end of this article to the embedded Internet application background . Analysis of the program structure of the embedded Web server , an embedded Web server is designed and implemented . The server can support industrial equipment, household appliances connected to the Internet , low- cost , simple design , easy to upgrade , and has a good dynamic Web pages function . Well positioned to meet the demand for household appliances and industrial equipment to access the Internet .
