As shown in fig. 1, system architecture 100 may include terminal device 101, network 102, and server 103. Network 102 is the medium used to provide communication links between terminal devices 101 and server 103.

Optionally, various client applications, such as an image processing application, a music playing software application, and the like, may be installed on the terminal device 101.

After the camera shoots the image, the image can be converted into data which accords with the MIPI protocol and then is sent out. The central processing unit may receive various data, for example, data according to the MIPI protocol, which is sent by the camera.
The terminal apparatus 101 may be hardware or software. When the terminal device 101 is hardware, it can be various electronic devices including, but not limited to, a robot, a face recognition system, and the like. When the terminal apparatus 101 is software, it can be installed in the electronic apparatuses listed above.

And is not particularly limited herein.

When the server is software, it may be implemented as multiple pieces of software or software modules (e.g., software or software modules used to provide distributed services), or as a single piece of software or software module. And is not particularly limited herein.
Here, the method for transmitting data provided by the embodiments of the present disclosure is generally performed by a terminal device (or an FPGA chip included in the terminal device). Accordingly, the means for transmitting data are typically provided in the terminal device.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for transmitting data in accordance with the present disclosure is shown. The method for transmitting data comprises the following steps:
In this embodiment, an executing body (e.g., the terminal device shown in fig. 1) of the method for transmitting data may acquire target data conforming to the MIPI protocol.
The target data may be any data conforming to the MIPI protocol. As an example, the target data may be image data (e.g., pixel information of an image captured by a camera).
In practice, MIPI signal lines are typically used to transmit data (including target data) conforming to the MIPI protocol. Therefore, the execution body can acquire target data conforming to the MIPI protocol through the MIPI signal line.
Generally, the long distance transmission of MIPI data (i.e., data conforming to the MIPI protocol) is prone to signal interference, and therefore, the length of a MIPI signal line is often less than 10 centimeters.
In this embodiment, the execution main body may convert the target data, which is obtained in step 201 and conforms to the MIPI protocol, into data (i.e., transmission data) conforming to a USB (Universal Serial Bus) protocol.
It is understood that the MIPI protocol specifies that 200 mv is in packets during transmission, that packets are in packets, and that 1.2 v is between packets and at packet start and end. Two different sets of LVDS (Low-Voltage Differential Signaling) driving circuits are required to work in alternate switching. For safe and reliable transition between data packets in the transmission process, the MIPI protocol defines a relatively long reliable transition time from start to data transmission, which adds up to 600 nanoseconds. Furthermore, it is also specified that each time parameter is adjustable, so that a certain waiting time is required, buffering is required, and a register can be used to replace a FIFO (First in First out) memory, with 128 bytes per channel.
Specifically, the executing entity may convert the target data into transmission data conforming to the USB3.0 protocol, or may convert the target data into transmission data conforming to the USB2.0 protocol.
Here, the execution body may convert the target data into the transmission data conforming to the USB protocol using at least one Programmable Device (PLD) of a Programmable Logic Array (PLA), a Programmable Array Logic (PAL), a General Array Logic (GAL), an Erasable Programmable Logic Device (EPLD), a Complex Programmable Logic Device (CPLD), and a Field Programmable Gate Array (FPGA).
For example, the execution body may adopt an FPGA chip to convert the target data into transmission data conforming to a USB protocol.
It can be understood that the FPGA chip includes a programmable input/output unit, a configurable logic block, a digital clock management module, an embedded block RAM (Random Access Memory), a wiring resource, an embedded dedicated hard core, and a bottom layer embedded functional unit. Technicians can analyze target data conforming to the MIPI protocol, and then program the target data on an FPGA chip through languages such as VHDL (Very High Speed Hardware Description Language) and Verilog, so that the target data are converted into transmission data conforming to the USB protocol.
In this embodiment, the execution body may use a USB2.0 or USB3.0 data line to transmit the transmission data to the data receiving end. Accordingly, the transmission data may be data conforming to the USB2.0 protocol, or data conforming to the USB3.0 protocol.
The data receiving end may indicate a location in the execution body for receiving the transmission data.
It can be understood that the length of the USB data line is within 1.5 meters, which generally ensures the signal stability of the transmitted data.
It can be understood that when the execution main body described above transmits transmission data to the data receiving end using the USB3.0 data line, the transmission speed can be increased.
In this embodiment, the execution body may convert, at the data receiving end, the transmission data conforming to the USB protocol into data conforming to the MIPI protocol.
Here, the execution body may use at least one of a programmable logic array, a programmable array logic, a general array logic, an erasable programmable logic device, a complex programmable logic device, and a field programmable gate array disposed at the data receiving end to convert the transmission data into data conforming to the MIPI protocol.
In some optional implementation manners of this embodiment, the execution main body may adopt an FPGA chip disposed at the receiving end to convert the transmission data into data conforming to the MIPI protocol.
It can be understood that a technician can parse target data conforming to the USB protocol, and then program the target data on the FPGA chip through languages such as VHDL and Verilog, so as to convert transmission data conforming to the USB protocol into data conforming to the MIPI protocol.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for transmitting data according to the present embodiment. In the application scenario of fig. 3, the face recognition robot 30 transmits target data 302 conforming to the MIPI protocol from the camera 301 (for example, through a MIPI signal line) to a location 303 in the face recognition robot 30 (for example, the location 303 may be provided with an FPGA chip for converting data conforming to the MIPI protocol into data conforming to the USB protocol). Thereafter, the face recognition robot 30 may convert the target data 302 into the transmission data 304 conforming to the USB protocol, and then the face recognition robot 30 may transmit (e.g., transmit through a USB data line) the transmission data 304 from the location 303 to the data receiving terminal 305 (the data receiving terminal 305 may be provided with an FPGA chip for converting the data conforming to the USB protocol into the data conforming to the MIPI protocol). Finally, the face recognition robot 30 may convert the transmission data 304 into data 306 conforming to the MIPI protocol at the data receiving end 305. Optionally, the face recognition robot 30 may also transmit the data 306 conforming to the MIPI protocol from the data receiving terminal 305 to the central processing unit 307 in the face recognition robot 30.
It should be noted that the application scenario shown in fig. 3 is only an example of the embodiment, and should not play any limiting role in the embodiment of the present application.
According to the method for transmitting data provided by the embodiment of the disclosure, the target data conforming to the MIPI protocol is obtained, then the target data is converted into the transmission data conforming to the USB protocol, then the transmission data is transmitted to the data receiving end, and finally the transmission data is converted into the data conforming to the MIPI protocol at the data receiving end, so that the quality of the MIPI data received by the receiving end can be ensured in an application scene of transmitting the MIPI data at a longer distance.
In some optional implementations of this embodiment, the length of the USB3.0 data line is greater than 10 centimeters.
It can be understood that in the prior art, MIPI signal lines are generally used for transmitting MIPI data, and the long-distance transmission of MIPI data is easy to generate signal interference, so that the length of the MIPI signal lines is often less than 10 centimeters. In the above optional implementation manner, the length of the USB3.0 data line may be greater than 10 centimeters, so that the transmission distance of the MIPI data may be increased.
In some optional implementations of this embodiment, the length of the USB3.0 data line is greater than 50 centimeters.
It will be appreciated that MIPI data tends to need to be transmitted over long distances for large devices. For example, the distance between a camera and a central processing unit in a large device is often 50 cm to 1 m, and thus, data conforming to the MIPI protocol needs to be transmitted by 50 cm to 1 m. When the length of the USB3.0 data line is greater than 50 cm, signal interference can still be reduced, and the quality of data transmitted in the USB data line (i.e., transmission data conforming to the USB3.0 protocol) is ensured, so the above optional implementation manner can be applied to more transmission scenarios of MIPI data, and signal interference caused by long-distance transmission of MIPI data is reduced.
In some optional implementations of this embodiment, the executing main body may execute the step 201 as follows: and acquiring target data which accords with a MIPI protocol of a mobile industry processor interface from the target camera. The target data represents image data of an image shot by the target camera.
Based on this, the execution main body can also adopt the USB3.0 data line to transmit target data conforming to the USB3.0 protocol and non-target data conforming to the USB2.0 protocol.
In this scenario, the execution subject may be an electronic device (e.g., a large-scale face recognition system) including a camera. In addition, the target camera may also be a camera communicatively connected to the execution main body, and in this scenario, for example, the execution main body may at least include: the system comprises an FPGA chip for converting data conforming to the MIPI protocol into data conforming to the USB protocol, an FPGA chip for converting data conforming to the USB protocol into data conforming to the MIPI protocol, and a USB data line for connecting the two FPGA chips.
Here, the executing body may transmit the data conforming to the MIPI protocol obtained in step 204 from the data receiving end to the central processing unit in the executing body. As an example, the execution body may transmit data conforming to the MIPI protocol from a data receiving end to the central processing unit in the execution body through the MIPI signal line.
The non-target data may include data other than the target data, which is transmitted between the target camera and the central processing unit. For example, the non-target data may include data sent by the processor to the target camera for controlling the target camera.
It is understood that the USB3.0 data line can be used to transmit data conforming to both the USB3.0 protocol and the USB2.0 protocol. Here, the execution main body may adopt a USB3.0 data line to transmit non-target data conforming to a USB2.0 protocol, and complete functions such as configuration and status check of a target camera, without adding a cable, so that the system is simplified.
In some optional implementation manners of this embodiment, the execution main body may further supply power to the target camera through a USB3.0 data line.
It can be understood that, in the above alternative implementation manner, the power supply function of the USB3.0 data line may be utilized to supply power to the target camera by adding a voltage conversion device at one end of the target camera.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method for transmitting data is shown. The method for transmitting data comprises the following steps:
In this embodiment, step 401 is substantially the same as step 201 in the corresponding embodiment of fig. 2, and is not described here again.
And 402, converting the target data into transmission data conforming to a Universal Serial Bus (USB) protocol by adopting an FPGA chip.
In this embodiment, an execution main body (for example, the terminal device shown in fig. 1) of the method for transmitting data may employ an FPGA chip to convert target data into transmission data conforming to the USB protocol.
It can be understood that the FPGA chip contains a programmable input/output unit, a configurable logic block, a digital clock management module, an embedded block RAM, a wiring resource, an embedded special hard core and a bottom layer embedded functional unit. Technicians can analyze target data conforming to the MIPI protocol and then program the target data on an FPGA chip through VHDL and/or Verilog languages, so that the target data are converted into transmission data conforming to the USB protocol.
In this embodiment, step 403 is substantially the same as step 203 in the corresponding embodiment of fig. 2, and is not described herein again.
And step 404, converting the transmission data into data conforming to the MIPI protocol by adopting an FPGA chip arranged at a receiving end.

It should be noted that, besides the above-mentioned contents, the embodiment of the present application may further include the same or similar features and effects as the embodiment corresponding to fig. 2, and details are not repeated herein.
As can be seen from fig. 4, in the process 400 of the method for transmitting data in this embodiment, the FPGA chip is used to convert the target data conforming to the MIPI protocol into the transmission data conforming to the USB protocol, and after the target data is transmitted for a certain distance, the FPGA chip is used to convert the transmission data conforming to the USB protocol into the data conforming to the MIPI protocol. For adopting proprietary chip to turn into the data that accords with the MIPI agreement with the data that accords with HDMI (High Definition Multimedia Interface) agreement, reuse another proprietary chip to turn into the technical scheme that accords with the data of MIPI agreement with the data of HDMI agreement, not only can reduce the price of the chip that uses, moreover, adopt USB data line transmission data, for adopting the HDMI line, can reduce the price of data line, reduce the use quantity of data line, simplify the complexity of the hardware connection who is used for transmitting MIPI data.
