Specific embodiment

To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application In attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art Every other embodiment obtained without making creative work, shall fall in the protection scope of this application.

Referring to FIG. 1, method for remote updating of the Fig. 1 for FPGA board in a kind of local area network provided by the embodiment of the present application Flow chart, which includes:

S101: Xiang Suoshu FPGA board sends the first broadcast packet, and first broadcast packet includes inquiry request, to determine State the board ID of FPGA board；

First broadcast packet is practically used for the quantity of inquiry FPGA board and the board ID of each FPGA board, specifically, this Step may include following three step:

Step 1, server end startup program establish socket connection, using report formula (SOCK_DGRAM) socket type, It is broadcast data packet (SO_BROADCAST) that setting, which sends type of data packet,.

Step 2, broadcast transmission data packet send the quantity of FPGA board according to the protocol contents defined with FPGA board Inquiry request waits the response of FPGA board.

Step 3, the characteristic due to broadcast packet, the FPGA board in all local area networks can all receive data packet, and root According to the protocol analysis packet content of definition, it is the discovery that the board inquiry request of FPGA, FPGA board can send according to agreement and answer It answers inquiry data packet and inserts the ID of FPGA board in reply data packet and be sent to server.

Particularly, server can also establish finger daemon for receiving the order of FPGA board transmission, receive FPGA After the response that board is sent is inquired data packet and parsed, the corresponding structural body number of FPGA board is established according to the quantity of different ID numbers Group, which is used to store the information of each FPGA board, by board ID, MAC Address and IP address with array form It saves.

S102: Xiang Suoshu FPGA board sends the second broadcast packet, to be the FPGA board point according to the node ID With MAC Address and IP address；

This step may include following three step:

The first step after determining FPGA board quantity by ID identification process, is divided according to each unique ID number of FPGA board With unique MAC and IP address information.And it is stored to the Array for structural body for the storage FPGA board information established in S101 In.

Second step, server send address configuration request according to the protocol requirement of definition, and according to the address ID+MAC+IP The form of address information, length are 12 bytes, fill broadcast packet, since Ethernet payload capacity is 1500 bytes, are subtracted It is 1472 bytes after IP radical and UDP radical, so a broadcast packet can at most configure 120 FPGA boards, if FPGA Board quantity is more than 120 multiple broadcast packets can be used to send, and the response of FPGA board is waited after being sent completely.

Third step, the characteristic due to broadcast packet, the FPGA board in all local area networks can all receive data packet, and root According to the protocol analysis packet content of definition, it is the discovery that address configuration request, and confirming by judging ID is that this is arranged MAC and IP address still directly abandon this broadcast packet, and after MAC and IP address success is arranged, FPGA board can be sent out according to agreement It send response address to be arranged successfully and the ID of FPGA board filling response bag is sent to server.

Preferably, server is using the finger daemon established in previous step, with receiving the response of FPGA board transmission After location is arranged successfully data packet and parses, the structural body of storage FPGA corresponding ID board information is found according to ID number, and address is set Store Success Flag.

S103: third broadcast packet is sent in local area network, so that the FPGA board is read and write in the third broadcast packet Rpd, which updates file and updates file according to the rpd, carries out board update.

After determining FPGA board quantity by ID identification process, distributed according to the unique ID number of each FPGA board unique MAC and IP address information.And it is stored in the structural body of storage FPGA board information of step 4 foundation.

Server sends address configuration request according to the protocol requirement of definition, and is believed according to the address ID+MAC+IP address The form of breath, length are 12 bytes, fill broadcast packet, since Ethernet payload capacity is 1500 bytes, subtract IP radical With after UDP radical be 1472 bytes, so a broadcast packet can at most configure 120 FPGA boards, if FPGA board number Multiple broadcast packets can be used more than 120 and send for amount, and the response of FPGA board is waited after being sent completely.

Due to the characteristic of broadcast packet, the FPGA board in all local area networks can all receive data packet, and according to definition Protocol analysis packet content, be the discovery that address configuration request, and confirm by judging board ID it is that this MAC is set This broadcast packet is still directly abandoned with IP address, after MAC Address and IP address success is arranged, FPGA board can be sent out according to agreement It send response address to be arranged successfully and the board ID of FPGA board filling response bag is sent to server.

Server uses finger daemon, and the response address for receiving the transmission of FPGA board is arranged successfully data packet and parses Afterwards, the structural body of storage FPGA corresponding ID board information is found according to ID number, setting address stores Success Flag.

Server reads the rpd file for remotely updating into memory.Since the Flash characteristic of FPAG board limits, The data of 64bytes can only be once written in the write operation of Flash, and a read operation can only at most read the 256bytes of Flash Data send the Flash write operation requests of FPGA according to protocol requirement based on above-mentioned theory, and data are filled into data Bao Zhong, each broadcast data are 64bytes, and broadcast data packet is sent 4 times, in total 256bytes, and in each data packet Increase the sequence that serial number is used to determine every bag data, the response of FPGA board is waited after being sent completely.

Due to the characteristic of broadcast packet, the FPGA board in all local area networks can all receive data packet, and according to definition Protocol analysis packet content, the Flash write operation requests of FPGA are the discovery that, and parse data sequence number, by received 4 groups of numbers According to being written in Flash after sequence, the 256bytes data in Flash are read again after the completion of write-in, FPGA board can root Response Flash write operation requests are sent according to agreement and the ID of the data read out and FPGA filling response bag are sent to service Device.

Server uses finger daemon, receives the response Flash write operation requests data packet of FPGA board transmission and solves It after analysis, is compared by the 256bytes with transmission, confirms whether the write request of Flash succeeds, storage is found according to ID number The structural body of FPGA corresponding ID board information, if Success Flag is successfully arranged and carries out success count, if unsuccessfully executed out Wrong treatment mechanism.

It is performed repeatedly until that all rpd, which are updated file, all to be updated into the Flash of FPGA board, and long-range update is completed Process.

After FPGA board is completed to update, in order to determine that all FPGA boards remotely update completion, sent out according to protocol requirement It send FPGA board remote loading to request, waits the response of FPGA board.

It specifically may include: to send remote loading request to FPGA board；If FPGA board loads successfully, FPGA plate Card is updated successfully.

Due to the characteristic of broadcast packet, the FPGA board in all local area networks can all receive data packet, and according to definition Protocol analysis packet content, be the discovery that FPGA remote loading request, FPGA execute remote loading success after, FPGA board The request of response Flash remote loading can be sent according to agreement and the ID of FPGA filling response bag is sent to server.

Server uses finger daemon, receives the response Flash remote loading request data package of FPGA board transmission simultaneously After parsing, the structural body of storage FPGA corresponding ID board information is found according to ID number, and remote loading Success Flag is set, this is arrived The long-range update and load of FPGA is fully completed.

Error handling processing mechanism is described below:

When any of third broadcast packet and subsequent all broadcast packets send failure or send time-out, the FPGA is utilized The corresponding MAC Address of board and IP address reassemble into unicast packet and are sent to the FPGA board.

It is not played a role in ID identification process and MAC and IP address configuration process, reason is if the two processes Error, can be determined that hardware problem, Ethernet cannot recognize FPGA board equipment substantially.

It updates long-range in loading procedure, due to the characteristic of Ethernet, having small probability, there are some data packet packet losses The problem of, in the finger daemon that a upper embodiment is established, the corresponding FPGA plate of all ID can be detected after sending data packet every time The execution state of card, and there are timeout mechanisms, if it find that certain reception state is failure and timeout case occurs, if two Kind of situation exists simultaneously, and represents data-bag lost, or operation is unsuccessful, and server will use the FPGA board of error ID at this time MAC and IP address recombinate a unicast packet be transmitted directly to corresponding FPGA board, with reach quick response error machine The purpose of system.

Due to the default ID number that FPGA board is arranged there are one according to the sequence of factory, guarantee the ID of each FPGA board It independently and does not repeat, server confirms there are how many FPGA boards in current local area network by broadcast packet, and gives board used Fixed MAC Address and IP address are configured, the long-range file that updates all is sent to all FPGA by way of broadcast packet later Board is remotely updated, all FPGA board reply data packets, synchronizing information is completed, if server is sent out in communication process Some existing FPGA board communication mistake individually can send unicast packet to error FPGA board, until being finally reached all The purpose that FPGA board remotely updates.Last server sends remote loading order by way of broadcast again, makes FPGA board Load recent program.Broadcast data packet form of this method due to using Ethernet, greatly shortens the time remotely updated, right All FPGA boards are updated there are Error disposal mechanism, enhance the reliability of system, and due to only using existing network interface card electricity Road does not need to carry out other modifications, avoids being significantly increased for hardware cost.
