Abstract

This invention discloses an intelligent Ethernet card with hardware acceleration function. The network card has the embedded high-performance processor, and designs two fiber Gigabit Ethernet interfaces and two copper Fast Ethernet interfaces, the network bandwidth being as high as 2.2Gbps, attached with the large capacity memory and the hardware acceleration module configured by user program. The network card uses 64-Bit/133MHz PCI-X interface, with PCI-X V1.0A and PCI V2.3 bus specification. The network card can be used in the servers with higher requirement to the network processing capacity, and using the powerful network processing capacity of the network card, it can unload many needs in the server to the network card, processed by network card processor and hardware acceleration module, thus reducing the pressure on the server, increasing the overall system processing power.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to an intelligent Ethernet card with hardware acceleration function. Background technique [0002] The development of computer has entered the network era, and the server-client application mode has been greatly developed. In this application mode, one of the main tasks of the server is to send, receive and process network data packets. With the continuous development of the Internet and the increasing popularity of broadband networks, the requirements for server performance are also getting higher and higher. However, when the Ethernet leaped from the 100M network to the Gigabit network era, people found that the processing of a Gigabit Ethernet data stream can easily consume most of the processing power of the server processor. Through further research, it is found that at this time The main job of the CPU is to respond to interrupts, and do some relatively simple but ...
