Abstract


With the recent rapid development of Internet and network applications more rapid promotion , people increasingly satisfied with the traditional network equipment processing capability. Thus , specifically for network data processing dedicated network processor came into being. Network processor is a programmable multi-core chips , both the ASIC 's performance and the flexibility of general-purpose processors . Therefore, how according to the required function to initialize the network processor configured to hardware performance given full play to its functions and meet the people 's expectations is very important . This paper describes the basic XDNP network processor hardware structure and characteristics , elaborated on the initial configuration and network processor status register information. Focuses on the XDNP network processor initialization configuration mechanism , a detailed analysis of the various sub -chip module initialization configuration process and results , multi-threaded packet processing engine microcode loading process , the default routing table creation , as well as off-chip MAC device the initial configuration . In addition , the paper also proposes a network processor specifically for XDNP initial configuration of custom control processor module, and based on the specific configuration of the network processor initialization conditions to design the module structure and configuration control , and ultimately through the module right XDNP network processor initialization parameter configuration . Finally , with the Xilinx Virtex-4 FPGA daughter board with Fids12mc2 motherboard built FPGA-based network processor XDNP initial configuration verification platform , and carried out through the verification platform XDNP each sub-module system verification , validation results show that the control module can work effectively.
