The Implementation Of Embedded TCP/IP Protocol Stack Based On DSP

With the development of information and network, the direction of development of embedded system is network, especially, its combination with Internet. The thesis discusses the thought and method of the design of embedded system combining with network. Moreover, a testing platform of embedded system based on DSP is designed to implement the TCP/IP protocol stack.In terms of hardware design, the testing board as a hardware platform is designed with TMS320VC5509A as its microcontroller, which is a widely used DSP. The microcontroller provides Ethernet interface with controlling CS8900A, which is used frequently in the network system. The thought and method about the hardware design of the collecting module is introduced in the thesis, including the selecting of the component and the design of the interface.In terms of software design, most work is done to replant and cut down the open-codeμC/OS II and TCP/IP stack. The thesis introduces uIP and LwIP as the embedded TCP/IP protocol stack differently. In this thesis, the experience in replanting uIP and LwIP based onμC/OS II to DSP is presented, and the thought and method of the design of service driver program is provided. Moreover, some experiments are given to illustrate the implementation of the task of network communication inμC/OS II and the implementation of the method of network communication about TCP/IP stack such as uIP and LwIP with its API functions. The end of the thesis analyses the results of the experiments.
