| Abstract: | With Digital Signal Processor (DSP) and Field Programmable Gate Array (FPGA) adopted as the kernel processors, the embedded network conversion gateway of high real-time was designed to realize the conversion between fieldbus and Ethernet. The conversion was finished on the physical layer and the data link layer, and the problem of direct communications between fieldbus and Ethernet was solved. The experimental results indicate that the feasibility and effectiveness of the design satisfy the requirements. |
