The user instruction is, for example, an instruction input by the user according to the command prompt information after the main card 11 starts the application command line, and specifically, the user instruction includes a task instruction to be executed from the card slot position information. Specifically, the user command is analyzed to obtain an initial communication command.

Example two
Fig. 2 is a schematic structural diagram of a backplane communication device according to a second embodiment of the present invention, and the technical solution of this embodiment is further detailed based on the above embodiments. Optionally, the master card 11 and each slave card 12 are respectively provided with a programmable logic device, and the programmable logic device 111 on the master card 11 is connected to the master card communication bus 101, and is configured to send the received initial communication instruction sent by the master card 11 to the master card communication bus 101; the programmable logic device 121 on the slave card 12 is connected to the slave card communication bus 102, and is configured to transmit the received communication result transmitted from the slave card 12 to the slave card communication bus 102.
The Programmable Logic Device (PLD) is a general-purpose large-scale integrated circuit, and a digital system with required functions is designed by adopting a method of combining software and hardware. The programmable logic device can be classified into a programmable combination logic device and a programmable sequential logic device according to the existence of register function, can be classified into a programmable logic array and a programmable gate array according to the internal circuit composition, and can be classified into a fuse programming logic device, an optical erasing programming logic device and an electric erasing programming logic device according to the programming mode. The specific type of programmable logic device is not limited herein.
In one embodiment, optionally, the programmable logic device 111 on the main card 11 is further configured to: converting an initial task instruction in the initial communication instruction to obtain a target task instruction based on a preset conversion rule, generating a target communication instruction based on the target task instruction, and sending the target communication instruction to the main card communication bus 101; accordingly, the programmable logic device 121 on the slave card 12 is also configured to: and after the matching is successful, analyzing the target task instruction in the received target communication instruction based on a preset conversion rule to obtain an initial task instruction.
For example, the preset conversion rule may be a rule characterizing a conversion mapping relationship between the initial task instruction and the target task instruction. For example, when the initial task instruction is a "word" instruction, the corresponding target task instruction is a "w" instruction. Accordingly, the programmable logic device 121 on the slave card 12 parses the "w" command based on the preset conversion rule to obtain a "word" command.
The method has the advantages that the initial task instruction sent by the main card can be simplified to obtain the target task instruction, and the target task instruction is sent to the main card communication bus, so that the data volume of the instruction transmitted on the communication bus is reduced, and the transmission efficiency is improved.
In an embodiment, optionally, the programmable logic device 111 on the main card 11 is specifically configured to: acquiring a master card slot position instruction, and generating a target communication instruction based on the master card slot position instruction, a target task instruction and a slave card slot position instruction in the initial communication instruction; accordingly, the programmable logic device 121 on the slave card 12 is also configured to: and generating a target result instruction based on the communication result, the slave card slot position instruction and the master card slot position instruction in the target communication instruction, and sending the target result instruction to the slave card communication bus.
Specifically, the master card slot position instruction is used to represent master card slot position information corresponding to the current master card. Fig. 3 is a schematic diagram of a target communication command according to a second embodiment of the present invention. As shown in fig. 3, the target communication command is a master slot position command, a slave slot position command and a target task command from left to right in sequence. It should be understood that, as shown in fig. 3, only one of the target communication commands is shown, and the present embodiment does not limit the sequence of the commands in the target communication command.
In an embodiment, the schematic diagram of the target communication command shown in fig. 3 may also represent a schematic diagram of a target result command. In this embodiment, the target result instruction is, from left to right, a slave slot position instruction, a master slot position instruction, and a communication result in sequence.
The advantage that sets up like this lies in, when being connected with a plurality of main cards on the backplate, the slave card can be according to the main card slot position instruction in the target communication instruction of receipt with the accurate main card that sends the target communication instruction of communication result, increased backplate communication equipment's adaptation scene to backplate communication equipment's portability has been improved.
In one embodiment, optionally, the programmable logic device 111 on the main card 11 is further configured to: before converting the initial task instruction, performing oversampling processing on the received initial communication instruction sent by the main card 11; and matching the initial task instruction in the initial communication instruction after the oversampling processing with the task instruction set, and if the matching is successful, executing conversion operation on the initial task instruction.
Specifically, the master card 11 and the programmable logic device 111 are respectively provided with a clock, when the master card sends an initial communication instruction to the programmable logic device 111 according to the master card clock, the programmable logic device 111 receives the initial communication instruction corresponding to the master card clock, and the logic processing of the programmable logic device 111 is completed based on the clock inside the programmable logic device 111 itself. If the master card clock is not synchronized with the internal clock of programmable logic device 111, then the logic processing performed by programmable logic device 111 based directly on the receipt of the initial communication command may have logic errors or inaccurate results. Therefore, the embodiment performs oversampling processing on the received initial communication command sent by the main card 11, thereby eliminating the interference problem of clock asynchronism and ensuring the accuracy of subsequent logic processing.
Here, the task instruction set is, for example, a task instruction defined in the programmable logic device 111 that can be executed, and if the initial task instruction does not match the task instruction set, the initial task instruction is not responded, that is, the user instruction corresponding to the initial task instruction is not responded. The advantage of setting up like this is, avoid sending invalid communication command, improves the transmission quality of communication command.
On the basis of the above embodiment, the programmable logic device 111 on the master card 11 receives the communication result sent by the slave card based on the initial communication instruction through the master card communication bus 101, and sends the display content corresponding to the communication result to the display of the backplane communication device, so that the display displays the display content.
According to the technical scheme of the embodiment, the programmable logic devices are respectively arranged on the master card and the slave card, and the programmable logic devices on the master card generate the target communication instruction based on the initial communication instruction sent by the master card, so that the problem of low transmission efficiency when the master card directly sends the initial communication instruction is solved, the programmable logic devices are used for further carrying out logic processing on the initial communication instruction sent by the master card, and the transmission efficiency and the transmission quality are further improved.
