| Abstract: | The design of network data transmission system based on DSP, CPLD and Ethernet is described. With TMS320VCG509A, EPM3128A and RTL8019AS as the core, the net interface circuit is designed, the TCP/IP is simplified and realized in DSP, the main program written in C language for data transmission between the system and the computer is designed, and the data transmission is finally implemented. The experiment result shows that the data transmission system constructed with DSP, CPLD and RTL8OI9AS could implement data transfer with between the computer through network and realize stable and reliable operation. |
