Research And Design Of SOPC Experimental System Based On Nios Processor

With the development of the embedded system, the advantages and disadvantages of employing ASIC or CPU to implement the digital system has been compared and analyzed. The design technology of SoPC(System on a Programmable Chip), which is based on the Nios embedded soft core processor, has been researched in the thesis.The performance and the characteristics of many embedded soft core processor styles were analyzed, and the structure, performance and on-chip bus regulation about Nios processor were emphatically studied, which is a new type of production in Altera Company. According to the requirement of general embedded system development, especially the design of cipher chip, a kind of scheme of experimental system based on Nios processor is provided. The function and component of experimental system were analyzed. The design scheme of the whole system is provided, and the key problems on the design and implementation of the experimental system were researched. Furthermore, the system was carried out.Finally, the experimental system was test and validated. By analyzing the test results, the correctness of the design scheme of the experimental system and the feasibility of the SOPC based on the Nios embedded soft core processor have been validated. The result of the research in this thesis settled technology basis in the design of on-chip chipper process system with the Nios processor.
