Abstract

The invention provides network equipment and a loading method of configuration files, which belong to the technical field of network communication. The network equipment comprises an embedded system and a first FPGA (Field Programmable Gate Array) device, wherein the first FPGA device is connected with the embedded system through a PCI-E bus. The network equipment also comprises a DMA (Direct Memory Access) device, wherein the DMA device is connected with the embedded system through the PCI-E bus, and is connected with the first FPGA device through an FPGA self-defined bus; and the DMA device is used for downloading the configuration files of the first FPGA device from the embedded system through a DMA manner, and uploading the configuration files into the first FPGA device. According to the network equipment and the loading method, the loading speed of the configuration files of the FPGA can be improved.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for loading network equipment and configuration files. Background technique [0002] Some network devices today can perform many business functions, such as packet filtering and flow monitoring, etc., and these services can be completed by the CPU or FPGA (Field Programmable Gate Array) of the network device. Comparing the two, since the CPU needs to control the overall operation of the system, if the business processing with a large flow is performed, the stability of the system operation and the performance of business processing will be greatly reduced. However, if the work of processing large-traffic services is handed over to the FPGA, the CPU of the device can be freed, and the overall performance and reliability of the device can be greatly improved. [0003] FPGA completes the circuit design through the hardware description language, develops the correspondi...
