Embodiment 1

[0045] Such as figure 2 Shown is a schematic structural diagram of Embodiment 1 of a Gigabit Ethernet composite network card provided by the present invention.

[0046] The CPU control module adopts a TLRx6480 many-core processor, and the TLRx6480 many-core processor has 64 cores.

[0047] Among them, the optical module includes two SFP+ interfaces and two SFP interfaces, 10 Gigabit Ethernet adopts SFP+ interface, and Gigabit Ethernet adopts SFP interface. The dimensions of SFP+ interface and SFP interface are compatible, so the optical module uses a four-in-one optical In the module box, the 10G interface uses the upper two positions, and the Gigabit interface uses the lower two positions.

[0048]The XFI (inter-chip electrical interface specification at a rate of 10 Gigabits per second) interface signal from the SFP+ interface of the optical module is converted into XAUI (10 Ethernet Attachment Unit Interface, an Ethernet connection unit at a rate of 10 Gigabits per second...

The many-core processor is used as the CPU processing module of the network card to achieve a balance between performance, power consumption and cost.

Description

technical field [0001] The invention relates to a high-performance network card, in particular to a gigabit and ten gigabit Ethernet composite network card. Background technique [0002] In the current market, there are generally several ways to implement 10GbE network cards: dedicated ASIC, NP processor, and FPGA. The solution implemented with ASIC has the highest line speed, but the function is very single and cannot be flexibly changed; the solution implemented with FPGA is very flexible in design, but the cost and performance are poor; the solution implemented with NP is powerful but costly, and because of its special architecture Programming is difficult. [0003] In view of the above problems, the present invention provides a way to implement a network card by using a many-core processor to achieve a balance between performance, power consumption and cost. Contents of the invention [0004] A Gigabit Ethernet composite network card provided by the present invention...
