[0043] Example 1
[0044] This application provides a multiplexing system for multiplexed drivers. Current multiplexing systems require direct multiplexing of the driver module 20, resulting in excessive waste of FPGA LUT resources. Therefore, this application proposes a multiplexing system that does not require direct multiplexing of the driver module 20, thereby improving the operational stability of the system program.
[0045] See Figure 1 The system includes: a control module 10, multiple drive modules 20, a channel selection module 30, and multiple output modules 40. The control module 10 is used to determine a target output module from the multiple output modules 40 according to actual functional requirements, generate a drive signal based on the target output module, and call the corresponding target drive module 20 from the multiple drive modules 20 according to the drive signal. The target output module includes M communication channels. The control module 10 is communicatively connected to the target drive module 20 and the channel selection module 30 respectively, and is also used to generate communication data and channel selection signals according to actual functional requirements. The target driving module 20 is communicatively connected to the channel selection module 30 and is used to generate an enable signal based on the communication data and the driving signal. The channel selection module 30 is communicatively connected to the target output module and is used to enable the target driving module 20 to communicate with the target output module based on the channel selection signal and the enable signal. The target driving module 20 generates a communication signal after communicating with the target output module. The control module 10 sequentially accesses the N communication channels according to a default order, and determines that the communication connection ends when the access of the N communication channels is completed.
[0046] It should be noted that the control module 10 determines the target output module from the plurality of output modules 40 according to the actual functional requirements, generates a drive signal according to the target output module, and calls the corresponding target drive module 20 from the plurality of drive modules 20 according to the drive signal.
[0047] To further explain, the control module 10 determines the number of channels based on functional requirements and hardware circuit design. The control module 10 generates a channel selection signal and simultaneously controls the target driver module to acquire output or input signals. It then multiplexes and selects the specific channel from which the communication signal is output or received. Specifically, if the requirement necessitates communication using 10 interfaces, communication must begin with the first channel. After the current channel has completed communication, the next channel is selected, and this process continues until all channels have completed communication.
[0048] In FPGA logic development, taking I2C driver multiplexing as an example, a single I2C target driver module 20 occupies nearly 170 lookup table resources. In the entire project design, the number of downstream I2C devices may range from zero to several hundred. In this case, directly calling the target driver module 20 is clearly not feasible. Therefore, the multiplexing system designed in this application can be used to meet the functional design requirements. See also... Figure 2 , Figure 2 A schematic diagram of another module of the multiplexing system provided in an embodiment of this application is shown.
[0049] The control module 10 is used to control the target driving module 20 to perform data acquisition to generate the enable signal. After receiving the communication signal fed back by the target driving module 20, it updates the channel selection signal and performs multiplexing selection on the M communication channels of the target output module according to the channel selection signal to determine the N communication channels of the target output module to be used, where M is greater than or equal to N.
[0050] Furthermore, the control module 10 is used to control the target driving module 20 to acquire data and generate the enable signal, and to multiplex and select multiple channels according to the channel selection signal to determine the multiple communication channels to be used. The multiple communication channels to be used are then used sequentially for communication, and the communication results fed back by the target driving module 20 are recorded. It is then determined whether all the determined communication channels have completed communication. If communication is confirmed to be complete, the communication ends.
[0051] In one embodiment, the plurality of output modules 40 includes: an I2C output module 41, an SPI output module 42, and a UART output module 43; the control module 10 is used to determine the target output module from the plurality of output modules 40 according to actual functional requirements.
[0052] Among them, I2C output module 41 is an I2C interface, SPI output module 42 is an SPI interface, and UART output module 43 is a UART interface.
[0053] Specifically, based on functional requirements, the target output module needs to use the I2C interface for communication, so the control module 10 needs to call the I2C driver module 21 during the design.
[0054] In one embodiment, the driving signal includes: an I2C driving signal, an SPI driving signal, and a UART driving signal; the plurality of driving modules 20 include: an I2C driving module 21, an SPI driving module 22, and a UART driving module 23; the control module 10 is used to invoke the target driving module 20 according to the driving signal.
[0055] In this embodiment, the control module 10 generates the data to be transmitted, read / write commands, and I2C drive signals to the I2C drive module 21, and simultaneously generates a channel selection signal to the channel selection module 30. The target drive module 20 generates SCL and SDA signals according to the I2C protocol and transmits the SCL and SDA signals to the channel selection module 30. The channel selection module 30 connects the SCL and SDA signals to the corresponding channel according to the channel selection signal provided by the control module 10. At this time, the I2C drive module 21 can communicate with the I2C output module 41 of the corresponding channel on the hardware circuit.
[0056] In one embodiment, the target driving module 20 is used to determine the type of data operation of the target output module; the control module 10 is used to determine that communication between the target driving module 20 and the target output module is complete after receiving the communication completion signal sent by the target driving module 20 and the read data if the data operation is a read operation.
[0057] The control module 10 is configured to determine, upon receiving a communication failure signal sent by the target driver module 20, that communication between the target driver module 20 and the target output module has failed if the data operation is a read operation.
[0058] It should be noted that data operations may involve read operations or only write operations. When a read operation is involved, in this embodiment, upon successful communication, the I2C driver module 21 will return a communication completion signal and the read data to the control module 10; if communication fails, the I2C driver module 21 will send a communication failure signal back to the control module 10. After receiving the feedback from the I2C driver module 21, the control module 10 updates the channel selection signal and proceeds to the next channel for communication until all channels have been accessed.
[0059] In one embodiment, the control module 10 is configured to determine that communication between the target driver module 20 and the target output module is complete after receiving the communication completion signal sent by the target driver module 20 if the data operation is a write operation.
[0060] The control module 10 is configured to determine, upon receiving the communication failure signal sent by the target driver module 20, that communication between the target driver module 20 and the target output module has failed if the data operation is a write operation.
[0061] It should be noted that data operations may involve read operations or only write operations. In this embodiment, after I2C communication is completed, if there is only a write operation in I2C, then the I2C driver module 21 will directly feed back the communication result of the write operation to the control module 10.
[0062] This embodiment provides a multiplexed drive system, comprising: a control module 10, multiple drive modules 20, a channel selection module 30, and multiple output modules 40. The control module 10 is configured to determine a target output module from the multiple output modules 40 according to actual functional requirements, generate a drive signal based on the target output module, and call the corresponding target drive module 20 from the multiple drive modules 20 based on the drive signal. The target output module includes M communication channels. The control module 10 is communicatively connected to both the target drive module 20 and the channel selection module 30, and is further configured to generate communication data and select channels according to actual functional requirements. The target driving module 20 is communicatively connected to the channel selection module 30 and is used to generate an enable signal based on the communication data and the driving signal. The channel selection module 30 is communicatively connected to the target output module and is used to enable the target driving module 20 to communicate with the target output module based on the channel selection signal and the enable signal. The target driving module 20 generates a communication signal after communicating with the target output module. The control module 10 sequentially accesses N communication channels out of the M communication channels according to a default order. When all N communication channels have been accessed, the communication connection is considered to have ended. This application can achieve the goal of saving resources while making reasonable and effective design, and the addition of a control module improves the stability of program operation by calling the driving module through the control module.

[0068] S303, the target driving module generates an enable signal based on the communication data and the driving signal.
[0069] S304, after the target driving module and the target output module establish a communication connection, a communication signal is generated.
[0070] S305, after receiving the communication signal fed back by the target driving module, the control module updates the channel selection signal and sequentially accesses the N communication channels of the target output module according to the default order. When the access of the N communication channels of the target output module is completed, the communication connection is determined to end.
[0071] In one embodiment, the target driving module determines the type of data operation of the target output module.
[0072] If the data operation is a read operation, the control module determines that communication between the target driver module and the target output module is complete after receiving the communication completion signal sent by the target driver module and reading the data; the control module determines that communication between the target driver module and the target output module has failed after receiving the communication failure signal sent by the target driver module.

The target driver module, communicatively connected to the channel selection module, generates an enable signal based on the communication data and the drive signal. The channel selection module, communicatively connected to the target output module, enables the target driver module to establish a communication connection with the target output module based on the channel selection signal and the enable signal. The target driver module generates a communication signal after establishing a communication connection with the target output module. The control module sequentially accesses N communication channels out of the M communication channels according to a default order; once all N communication channels have been accessed, the communication connection is considered complete. This application achieves both reasonable and effective design while conserving resources. Furthermore, the addition of a control module, which calls the driver module, improves the stability of program operation.
