Embodiment, present invention selection realizes NCSI protocol interface work(using the Cyclone V fpga chips of altera corp
Can, largely provide ethernet mac IP, such as Cyclone V systems in the SoC solutions that current Altera companies provide
Row chip.This IP like have cost it is low, using maturation the features such as, utilize this IP ethernet feature, it is possible to achieve NC-SI agreements
The encapsulation and parsing of pass-through bags and control bags in interface, connect so as to greatly reduce independent development NC-SI agreements
The workload of mouth.
As shown in figure 1, in network monitoring platform, network controller can carry out normal network service, meanwhile, it is stayed
Go out sideband data interface, for alloing Management Controller to monitor and managing network.Meanwhile, Management Controller can be with network
Controller shares network.Then in Management Controller, i.e., the logic of NC-SI protocol interfaces is realized, Ethernet is realized again
Logic.During independent research, to use to the management function of network controller in logic realization Management Controller,
It realizes that difficulty is larger, and the development time is longer.Be in the monitoring function controlled in view of Management Controller network with
Too based on fidonetFido, so, existing ethernet ip can be used in SoC systems to realize its function, this scheme is realized
Development time cost can greatly be saved by getting up, and can fully achieve the function of the part of this in Management Controller.
Fpga chip is divided into stone part and logical gate herein, specific steps are as shown in Figure 2.
First, in Quartus II engineering softwares, the Ethernet IP kernel of Cyclone V HPS sides is configured,
Using the IP of HPS sides, and the MII/GMII agreement pins provided are guided into fpga logic side handled.Altera's
Cyclone V family chips are divided into the logical gate of HPS sides stone part and FGPA sides, and wherein stone part then can be by
Ethernet ip function is realized in configuration.This ethernet ip using as in NCSI protocol interface functions to the parsing of Ethernet protocol and
Packing, and generation NCSI protocol data bags.Avoid the time of exploitation ethernet mac and cost again.
Then, the MII/GMII leg signals that HPS sides are provided are handled.
For MDIO signals, it is necessary to dock an ethernet PHY, due to not reserving the two letters in NCSI agreements
Number, therefore, a virtual PHY is built here by logic, is communicated by MDIO with MAC, so as to complete ethernet mac
Initialization procedure.The virtual process of ethernet PHY is defined PHY therein according to actual Ethernet PHY chip RTL8211e
Register.
Conversion of the MII protocol interfaces to RMII protocol interfaces.Because NCSI protocol interfaces are the bases in RMII protocol interfaces
Come on plinth, and it is MII protocol interfaces that the Ethernet interface of HPS sides, which is provided, so needing to carry out both in logic side to connect
The conversion of mouth.
Finally, the processing of speed is transmitted, because NCSI protocol interfaces may only be operated in 100Mbps and 10Mbps moulds
Under formula, so speed to be defined as to 100Mbps full duplex mode of operation in this scheme.Initialized in ethernet mac
During, it just can determine to use 100Mbps full duplex mode of operations by reading virtual PHY status register.This needs
The setting of related register in virtual PHY.
By embodiment above, the those skilled in the art can readily realize the present invention.But should
Work as understanding, the present invention is not limited to above-mentioned embodiment.On the basis of disclosed embodiment, the technical field
Technical staff can be combined different technical characteristics, so as to realize different technical schemes.
It is the known technology of those skilled in the art in addition to the technical characteristic described in specification.
