[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Combine the following Figure 1-Figure 6 The optical fiber communication data interaction processing method and device of the present invention are described, and the embodiments thereof are described in detail.

[0030] The following is a detailed description of an embodiment of the optical fiber communication data interaction processing method according to the present invention. Figure 1 As shown, it is a flow chart of the optical fiber communication data interaction processing method provided by the present invention, and the specific implementation process includes the following steps: Step 101, when writing fiber optic communication data to the memory cache area, trigger the running of a preset target program in the programmable array logic to determine the first target number of copies of the memory cache area occupied by the current write data packet according to the write data packet length of the fiber optic communication data, and update the write address offset recorded in the write channel management module in the target program and the remaining space of the memory cache area according to the first target number of copies and the capacity space of each copy, and use the write channel management module to save the data packet length information.

[0031] In an embodiment of the present invention, when the software of the computer device writes the optical fiber communication data into the memory cache area, before triggering the operation of the preset target program in the programmable array logic (i.e., Field Programmable Gate Array, FPGA), it is also necessary to query whether the remaining space of the memory cache area meets the write condition of the optical fiber communication data. When the remaining space of the memory cache area meets the write condition of the optical fiber communication data, the current write address offset is queried from the write channel management module in the target program of the programmable array logic; according to the current write address offset, the optical fiber communication data is written into the memory cache area, and after the writing is completed, the data packet length information of the optical fiber communication data is pre-configured to the write channel management module. The software is a computer program product running in a computer device (i.e., a computer device). It should be noted that before querying whether the remaining space of the memory cache area meets the write condition of the optical fiber communication data, it is also necessary to pre-divide the capacity space of the memory cache area into preset equal parts, obtain the target number of copies corresponding to the memory cache area and the capacity space of each copy, and synchronize the target number of copies corresponding to the memory cache area and the capacity space of each copy to the preset target program in the programmable array logic. The software refers to a program running on a PC or various processors. The target program preset in the programmable array logic is a program running in the FPGA or a data logic circuit inside the FPGA. The optical fiber communication data is data exchanged in an optical fiber bus communication system.

[0032] In this step, when the optical fiber communication data is written into the memory cache area, the target program preset in the programmable array logic is triggered to run, so as to determine the first target number of copies of the memory cache area occupied by the current write data packet according to the write data packet length of the optical fiber communication data and the capacity space of each pre-divided portion, such as dividing the write data packet length of the optical fiber communication data by the capacity space of each pre-divided portion, so as to obtain the number of copies of the memory cache area occupied by the current write data packet as the first target number of copies; the initial write address offset recorded in the write channel management module in the target program is obtained; Determine the increased write address offset according to the first target number of copies and the capacity space of each copy, such as determining the increased write address offset according to the product of the first target number of copies and the capacity space of each copy; determine the target write address offset according to the initial write address offset and the increased write address offset, such as summing the initial write address offset and the increased write address offset to obtain the target write address offset; based on the target write address offset, update the write address offset recorded in the write channel management module in the target program, and use the target write address offset as the updated write address offset; determine the occupied capacity space according to the first target number of copies and the capacity space of each copy, such as multiplying the first target number of copies and the capacity space of each copy to obtain the occupied capacity space; obtain the initial capacity space of the memory cache area; determine the actual remaining space based on the initial capacity space and the occupied capacity space, such as subtracting the initial capacity space from the occupied capacity space; and update the remaining space of the memory cache area based on the actual remaining space.

[0033] Step 102: When the target program detects the presence of data packets in the status information of the memory cache area, the data packets in the memory cache area are read and processed according to the data packet length information and the read address offset and using the data movement module in the target program, and the second target number of copies of the memory cache area occupied by the current read data packet is determined according to the read data packet length of the optical fiber communication data; according to the second target number of copies and the capacity space of each copy, the read address offset in the read channel management module of the target program is updated to release the capacity space corresponding to the data packet in the memory cache area.

[0034] In an embodiment of the present invention, when the target program is used to detect the presence of a data packet in the status information of the memory cache area, the data packet in the memory cache area is read and processed according to the data packet length information and the read address offset, and the data movement module in the target program is used to determine the second target number of copies of the memory cache area occupied by the current read data packet according to the read data packet length of the optical fiber communication data; the initial read address offset recorded in the read channel management module in the target program is obtained; the reduced read address offset is determined according to the second target number of copies and the capacity space of each copy, such as multiplying the second target number of copies and the capacity space of each copy to obtain the reduced read address offset; the target read address offset is determined according to the initial read address offset and the reduced write address offset, such as subtracting the initial read address offset from the reduced write address offset to obtain the target read address offset; based on the target read address offset, the read address offset recorded in the read channel management module in the target program is updated, and the target read address offset is used as the updated read address offset.

[0035] The software logic optical fiber communication data interaction processing implementation process proposed by the present invention is as follows Figure 2 As shown, the following takes the software running on Windows PC, the logic running on FPGA, and the communication based on PCIE interface as an example, the specific description is as follows: During the initialization process, the software is powered on and runs the driver program, and requests two buffers (i.e., memory caches) from the optical fiber bus communication system, one buffer for sending and the other for receiving. The buffer capacity can be 1MB, the starting addresses are buffer_addr_tx and buffer_addr_rx, and the two addresses are configured to the logic side; the logic side divides the buffer into 4096 equal parts (i.e., the target number of parts), each with a capacity of 256B (i.e., the capacity space of each part), and the remaining space of the two buffers is initially 4096, and the write address offset is , read address offset .

[0036] Specifically, during the process of software sending data, (a) the software running in the computer device executes a query to see if the remaining buffer space is 4096 and can be written to data; (b) the software executes a query to see if the write address offset ; (c) Software from The address is used to write data, and the length of the written data is 700B (selected according to actual needs); (d) After the software executes the data writing, the written data length (700B) is configured to the logical write address management channel; (e) The logic executes the update write address offset , the remaining space of the Buffer is 4093; (f) When the logic execution detects that there is data in the Buffer status information, it obtains the read address from the read channel and data length (700B), start DAM to read data from the corresponding position of Buffer to logic; (g) After the logic executes the read data, it updates the write address offset to , the remaining space of the Buffer is 4096, and the corresponding message length information in the fifo is cleared. The computer device is a server. The above process is the completion process of the software sending a message to the logic. In the whole process, the software repeats the first 4 processes in sequence; the logic repeats the last 4 processes in sequence. As long as the remaining space of the Buffer queried by the software is sufficient, the software can keep writing data, and the logic will continuously move data when it detects that there is data. As long as the DMA rate is fast enough, the remaining space of the Buffer will not be exhausted, and the software can send data continuously and uninterruptedly, and finally achieve a huge data throughput with high efficiency. From the above process, it can be seen that, except for DMA moving data, the logic software only has parameter transmission in the three processes of steps (a), (b) and (d), which is very concise and easy to implement.

[0037] In addition, in an embodiment of the present invention, the optical fiber communication data interaction processing method also includes a process in which the software of the computer device receives the logic to report the optical fiber communication data interaction. Wherein, the logic is the target program in the programmable array logic, that is, the target program in the FPGA. The software of the computer device is software running in a Windows PC. Specifically, by running the target program in the programmable array logic, it is queried whether the remaining space of the memory cache area meets the writing condition of the optical fiber communication data. When it is queried that the remaining space of the memory cache area meets the writing condition of the optical fiber communication data, the current write address offset is obtained from the write channel management module of the target program; according to the current write address offset, the data moving module of the target program is triggered to write the optical fiber communication data to the memory cache area through the target program in the programmable array logic, and the data packet length information of the optical fiber communication data is configured to the write channel management module and the read channel management module of the target program. When an interrupt signal sent by the target program in the programmable array logic is obtained, the data packet length information and the read address offset are obtained from the read channel management module of the target program, and the optical fiber communication data is processed according to the read address offset and the data packet length information. After the data processing is completed, the read address offset in the read channel management module is updated, and the capacity space corresponding to the memory cache area is released. That is, Figure 3As shown, the program running in the FPGA queries whether the remaining space in the memory cache area meets the optical fiber communication data writing condition. If so, the current write address offset is obtained from the write channel management module of the FPGA; according to the current write address offset, the data migration module is triggered to write the optical fiber communication data into the memory cache area, and the data packet length information of the optical fiber communication data is written into the write channel management module; in the case of obtaining an interrupt signal sent by the program running in the FPGA, the data packet length information and the read address offset are obtained from the read channel management module, and the optical fiber communication data is processed according to the read address offset and the data packet length information. After the data processing is completed, the read channel management module is notified to update the read address offset and release the capacity space corresponding to the memory cache area.

[0038] Specifically, during the process of receiving data, (a) the remaining buffer space is 4096 (sufficient remaining space) and data can be written through logical execution query; (b) the write address offset is queried logically ; (c) Logic execution starts DMA to The address is written with data, and the length of the written data is 7.5KB; (d) After the logic executes DMA writing, the written data length (7.5KB) is passed to the write address management channel to update the write address offset to , the remaining buffer space is 4066; (e) The logic execution generates an interrupt to notify the software that there is data to report; (f) The software detects whether the interrupt is received; (g) After receiving the interrupt reported by the logic, the software reads the read channel to obtain the read address The state management module obtains the data length (7.5KB) from (h) After the software completes the data processing, it notifies the logic to update the read channel address , the remaining space of the buffer is 4096 and the corresponding message length information in the fifo is cleared; The above process is the completion process of the software receiving a message reported by the logic. In the whole process, the logic repeats the first 5 processes in sequence; the software repeats the last 3 processes in sequence. As long as the remaining space of the buffer queried by the logic is sufficient, data can be written continuously. When the software detects that there is data, it can process the data continuously. As long as the DMA rate is fast enough, the remaining space of the buffer will not be exhausted, and the logic can report data continuously and uninterruptedly to achieve a huge data throughput with high efficiency. From the above process, it can be seen that in addition to DMA moving data, the logic software only has parameter transmission in steps (g) and (h), which is very concise and easy to implement.

[0039] In the present invention, in order to solve the technical problem described in the present invention, the following is adopted: Figure 2The hardware architecture shown is implemented. The driver on the software side of the computer device is responsible for reading, writing and processing data (i.e., optical fiber communication data); the DMA (Direct Memory Access) on the logic side of the FPGA is responsible for moving data between the software and the logic, where DMA can also be replaced by other existing data movement modules, which are not specifically limited here. The memory buffer (i.e., memory cache area) is provided by the software side, and both the logic and the software have read and write permissions to the memory cache area. During the operation of the optical fiber bus communication system, the management of the memory cache area is completed by the logic alone, and the software side no longer needs to undertake the corresponding management work, but can obtain the status of the memory cache area in real time from the logic side (remaining space, whether there is data, and the number of data packets to be processed, etc.).

[0040] The present invention discloses a method for managing a memory cache area on the software side and a method for data interaction between software and logic using optical fiber communication based on the method. In the present invention, the logic divides the buffer with a total capacity of S used for data interaction on the software side into N equal parts for management (N can be configured by agreement in advance between the software and the logic, and the larger N is, the more refined the management of the buffer is), and the capacity of each part is M=S / N, that is, the capacity space of each part. The logic divides the management of the buffer into a write channel management module, a read channel management module, and a status maintenance module (that is, a buffer status management module). The write channel management module is responsible for maintaining the write address offset of the buffer (that is, ) and records the length of the written data packet; the read channel management module is responsible for maintaining the read address offset of the Buffer and clear the packet length information; the status maintenance module is responsible for controlling the remaining space in the maintenance buffer, whether there is data included, and the number of packets. and The initial value is 0.

[0041] When the fiber communication data is written into the Buffer (memory cache area), the number of Buffer copies P (i.e. the first target number) occupied by the current write data packet is calculated based on the write data packet length (wpkg_len) through logic. If it is less than one copy, it will be processed as one copy. Then the write address offset (waddr_offset) is updated and the write data packet length (wpkg_len) is saved. When waddr_offset exceeds the Buffer address range, the high-order overflow is discarded and the address is rolled back. The write address offset update calculation formula is as follows:

[0042] That is, the initial write address offset recorded in the write channel management module in the target program is obtained ( ); According to the first target number of copies (ie, P) and the capacity space of each copy (ie, M), determine the increased write address offset (ie ); According to the initial write address offset and the increased write address offset, determine the target write address offset, based on the target write address offset (i.e. ), the write address offset recorded in the write channel management module in the target program is updated, and the target write address offset is used as the updated write address offset.

[0043] When the computer device finishes reading the optical fiber communication data from the Buffer, it calculates the number of Buffer copies L (i.e., the second target number) occupied by the currently read data packet through logic based on the read data length (rpkg_len). If it is less than one copy, it will be processed as one copy. Then, the read address offset (raddr_offset) is updated and the packet length information is cleared. When raddr_offset exceeds the Buffer address range, the high-order overflow is discarded and the address is rolled back. The calculation formula for updating the read address offset is as follows:

[0044] That is, the initial read address offset recorded in the read channel management module in the target program (i.e. ); According to the second target number of copies (ie, L) and the capacity space of each copy (ie, M), determine the reduced read address offset (ie ); According to the initial read address offset and the reduced write address offset, determine the target read address offset (ie ), based on the target read address offset, the read address offset recorded in the read channel management module in the target program is updated, and the target read address offset is used as the updated read address offset.

[0045] The buffer status management module includes: buffer remaining space, whether there are packets in the buffer, and the number of buffered packets. The initial value of the buffer remaining space is N. When a packet that occupies P buffers is written, the buffer remaining space is reduced by P; when a packet that occupies L buffers is read, the buffer remaining space is increased by L. Whether there are packets in the buffer and how many packets there are are obtained from the packet length information fifo.

[0046] Figure 3The figure shows the interactive mode of sending data from software to logic, which is divided into 8 steps. Among them, steps 1 to 4 are completed by software, and steps 5 to 8 are completed by logic. Only steps 1, 2 and 4 involve software and logic interaction, and the content of the interaction is the acquisition of status and configuration of parameters. The operation is very simple and error-prone. When the software transmits data to the logic, it only needs to focus on steps 1 to 4. As long as there is enough remaining space in the buffer in step 1, the software can continue to send data, which can effectively improve the efficiency of the software sending data.

[0047] Figure 4 The figure shows the interactive mode of software receiving logic reporting data, which is also divided into 8 steps. Among them, steps 1 to 5 are completed by logic, and steps 6 to 8 are completed by software. Only steps 6, 7 and 8 involve software and logic interaction. Step 6 is the interrupt signal generated by the software receiving logic. Steps 7 and 8 involve software and logic interaction, and the content of the interaction is also the acquisition of status and configuration of parameters. The operation is also simple and not prone to errors. To transmit data from logic to software, you only need to pay attention to steps 1 to 5. As long as there is enough remaining space in the buffer in step 1, the logic can continue to report data to the software, which can effectively improve the efficiency of logic reporting data.

[0048] In the traditional software logic interaction mode, the software and logic need to maintain a set of pointers to manage the buffer, which is cumbersome to design and has low interaction efficiency. The software logic data interaction mode designed based on the present invention is simple to implement, concise to interact, not prone to errors and has high interaction efficiency. At the same time, the running status of the buffer (remaining space, whether there is data, how many packets of data) can be clearly obtained, which is convenient for monitoring the operation of the system and locating bugs.

[0049] In order to solve the problems of complex software logic interaction mode, low efficiency, and great difficulty in implementation and maintenance in the FC-AE communication system, the present invention proposes a new software logic data interaction mode for the FC-AE communication system.

This method adopts the idea of ​​dividing the memory buffer into blocks and managing it separately by logic. Based on this design, the memory management work can be effectively simplified, making the software logic interaction process concise and easy to implement. The software logic data interaction method proposed by the present invention greatly simplifies the interaction process while ensuring sufficiently high communication efficiency. In addition, the memory management idea in this interaction method is also suitable for many systems that need to manage memory.
