In the embodiment of the present invention, the reactance recording device 200 uses the DDR memory 2123 as a high-speed data cache to ensure efficient and accurate transmission of the optical fiber data and ensure the integrity of the optical fiber data.
In the embodiment of the present invention, as shown in fig. 5, the method for determining target record data of the present invention includes the following steps:
In the embodiment of the present invention, the aurora ip2121 and the DDR memory 2123 have different clock frequencies, and it is necessary to perform clock domain crossing processing on the optical fiber data to be recorded sent by the aurora ip2121 by using the FIFOIP21221 of the recording module 2122, so as to ensure that the DDR memory 2123 can accurately and completely receive the target recorded data. For example, the clock frequency of AuroraIP2121 is a frequency a, the clock frequency of DDR memory 2123 is a frequency B, and the optical fiber data to be recorded sent by AuroraIP2121 needs to be processed into intermediate recording data with the frequency B, so that the intermediate recording data meets the clock frequency requirement of DDR memory 2123.
In the embodiment of the present invention, the recording module 2122 arbitrates the intermediate recording data, determines the data type of the intermediate recording data and the fiber path identifier of the AuroraIP2121 corresponding to the path source of the intermediate recording data, and constructs a correspondence between the fiber path identifier, the data type, and the data details to generate target recording data.
And step 104, the CPU acquires the target record data from the DDR memory and sends the target record data to the memory card for storage.
In this embodiment of the present invention, after the aurora ip2121 starts receiving and the recording module 2122 starts recording, the CPU211 acquires target record data from the DDR memory 2123 through the PCIE interface 2125, and sends the target record data to the memory card 220 for storage.
Further, when the CPU211 acquires the target record data from the DDR memory 2123 through the PCIE interface 2125, the target record data is processed across clock domains again to obtain the target record data meeting the clock frequency of the PCIE interface 2125.
In the embodiment of the present invention, when the CPU211 stores the target record data in the memory card 220, the target record data may be stored according to the storage address of the memory card 220, and the corresponding relationship between the target record data and the storage address is stored in a database (for example, mySQL database), so that when data playback is performed in a later period, the database may be searched, and the storage address may be determined to obtain corresponding optical fiber data.
In the embodiment of the present invention, as shown in fig. 6, the data playback method based on the FPGA fiber data includes the following steps:
In the embodiment of the invention, the first user, the second user and the third user can be the same or different, and the determination is carried out according to actual needs.
In the embodiment of the present invention, the CPU211 searches the database according to the data playback instruction, and determines the storage address of the optical fiber data to be played back.
In this embodiment of the present invention, the CPU211 sends a playback start instruction to the multiple aurora ips 2121 and the playback modules 2124 of the FPGA212 through the PCIE interface 2125 of the FPGA212, the multiple aurora ips 2121 and the playback modules 2124 enter a sending preparation state after receiving the playback start instruction, the playback module 2124 and the aurora ip2121 of the corresponding path are started, and optical fiber data to be played back is prepared for playback and sent.
In this embodiment of the present invention, alternatively, the CPU211 may send a playback start instruction to the control module 2129 of the FPGA212 through the PCIE interface 2125, so that the control module 2129 controls the multiple auroraips 2121 and the playback module 2124 to enter the sending preparation state.
In this embodiment of the present invention, the CPU211 sends the optical fiber data to be played back to the playback module 2124 through the PCIE interface 2125 of the FPGA 212.
Further, the fifofip of the playback module 2124 performs clock domain crossing processing on the optical fiber data to be played back, and determines target playback data that conforms to the clock frequency of AuroraIP.
Because the clock frequencies of the PCIE interface 2125 and the aurora ip2121 are different, the FIFOIP21221 of the playback module 2124 needs to perform clock domain crossing processing on the optical fiber data to be played back, which is sent by the PCIE interface 2125, so as to ensure that the aurora ip2121 can accurately and completely send target playback data. For example, the clock frequency of the PCIE interface 2125 is C frequency, the clock frequency of the aurora ip2121 is D frequency, and the to-be-played optical fiber data sent by the PCIE interface 2125 needs to be processed into target playback data with D frequency, so that the target playback data meets the clock frequency requirement of the aurora ip 2121.
In this embodiment of the present invention, before the CPU211 sends the optical fiber data to be played back to the playback module 2124 through the PCIE interface 2125, the CPU211 may query the buffer space of the playback module 2124 through the PCIE interface 2125, determine whether the buffer space of the playback module 2124 has a storage space, and if yes, send the optical fiber data to be played back to the playback module 2124; if not, the transmission of the optical fiber data to be played back to the playback module 2124 is suspended, the release of the cache space of the playback module 2124 is waited, and the optical fiber data to be played back is transmitted to the cache space of the playback module 2124 after the cache space of the playback module 2124 is determined to have the storage space.
In the embodiment of the present invention, multiple auroraips obtain target playback fiber data that meets the clock frequency of the playback module 2124, and send the target playback fiber data to a corresponding third user, so that the target playback fiber data is played back to the third user through a fiber interface.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
