Abstract: The development of autonomous controllable processors is of great strategic significance to the construction of socialism with Chinese characteristics in a new era in our country. After more than a decade of development, China-made Shenwei processors have made remarkable achievements in supercomputer and other fields and have basically got the ability to contend with today's advanced international processors.DPDK is a set of data plane development tools provided by intel, which is composed of a series of function libraries and network card drivers. Developers can use these libraries for secondary development to quickly process network data packets. Based on the DPDK, the user-mode network protocol stack is implemented, and the user-mode protocol stack avoids interruptions and avoids unnecessary context switching, making a true zero-copy and becoming more and more important in cloud computing and big data scenarios. DPDK is playing an increasingly important role in SDN and NFV and has gradually become the de facto standard. The DPDK transplant to the domestic Shen Wei processor hardware platform, not only can significantly improve Shen Wei platform based network equipment packet processing capabilities, but also can be extended Shen Wei hardware platform in high performance computing, big data platforms, security equipment, As well as the server field application. This paper firstly expounds the significance of DPDK porting to domestic Shen Wei processor platform, and briefly describes the architecture and core technologies of DPDK. Then it analyzes the difficulties of porting DPDK to SW processor platform, and describes the migration work Finally, the article briefly describes the design and implementation of the SW411 processor-based firewall prototype and compares the performance of the prototype before and after migration to verify that the DPDK can be ported to the Shen Wei platform effect.
