Realization of Internet system based on SOPC

SOPC is a kind of new-embedded design technology. It is also a kind of elementary design technology that software and hardware are designed in coordination. The necessary systematic design things are integrated on PLD device, such as processor, memory, I/O interface, LVDS and CDR, it can establish a system on a programmable chip. Nois soft core embedded processor is a kind of permissible RISC CPU, the Altera company offers it to the designers with the way of IP core. It may form a SOPC, with various peripheral equipment, custom-made instruction and hardware acceleration unit combination. Nios still has software development wrap, including compiler, integrated development environment, JTAG debugger, real-time operating system and TCP/IP Through a design example, the paper has introduced the development process of SOPC. It has analyzed the working principle of every composition part in this paper It has given Ethernet interface adapter design scheme. The Ethernet remote data collection module can carry out data collection, data remote transmission as well as remote control. Combining the debug process of SOPC development board, it has discussed the problem and solutions in the debug process.
