Abstract


With microprocessor technology and the Internet technology continues to evolve , the embedded system applications into all walks of life . Embedded products information appliances as the representative of the age of the Internet , not only for embedded applications market to show a better future , but also on the embedded system technology , especially software technology new challenges . This mainly includes : easy and flexible network to support the growing connection , rational and effective use of limited resources , a stable and efficient work long hours . X86 architecture - based embedded operating system uC / OS - II transplantation , mainly discusses the key technologies of operating system migration and TCP / IP network protocol stack the LWIP transplantation . The main contents are as follows : 1 . Embedded real-time systems review . This section describes the embedded system development process and main features . UC / OS - II analysis and X86 load and run . The design uses the way of the floppy disk , load and run uC / OS - II system image file , at the same time in order to meet the needs of uC / OS - II flat memory touch-type running , the switch from real mode to protected mode . 3. Research and the transplant TCP / IP protocol stack LWIP to uC / OS - II . Embedded system features full analysis and research on the basis of the TCP / IP protocol stack LWIP and uC / OS -II to be modified to make it suitable for embedded system resources and efficiency requirements . RTL8139 NIC driver in the preparation . This chapter details the data structure associated with the network device driver interrupt handler. Gives the driver complete process . Proven , implemented in this article uC / OS - II transplantation stable and reliable operation .
