Abstract


The high-performance processor core is the most critical part of the core of the embedded system . Widely used in embedded system design , 32 -bit RISC processor , such as the the ARM company's ARM processor , IBM's Power PC processor , MIPS MIPS processor , etc. is a commercial kernel , the user must pay relatively expensive licensing fees . The OR1200 its completely open source code and compiler attracted designers, its simple structure , versatility and portability , with a complete development platform , ideally suited for embedded system design . About OR1200 research also is being more and more attention in both academia and industry . This article is combined in this context mentor commitment Qingdao Municipal Science and Technology Bureau projects to study to achieve a chip the embedded SOC gateway based on open source microprocessor . On the OR1200 and other wishbone bus interface peripheral IP soft core FPGA design and verification , embedded SoC gateway IC front-end system design, and build the OR1200 the SoC hardware platform . In OR1200 SoC hardware platform based on the transplantation of embedded real-time operating system to add network support , the ultimate goal is to achieve an embedded SOC gateway chip . Operating system select uC/OS- Ⅱ real - time operating system . The network protocol stack, the choice of a lightweight embedded Ethernet protocol the stack LWIP . The system to achieve FPGA , frequency up to 20MHz, with a stable network functionality . The system is realized on a FPGA chip front-end embedded SOC gateway chip design , the system can be directly applied in systems such as routers , can also be used in of ASIC embedded SoC Gateway chip front-end design .
