Referring to fig. 2, fig. 2 is a schematic flow chart of a display signal transmission method according to a first embodiment of the present invention.

In this embodiment, the display signal transmission method includes the following steps:

step S10: and acquiring a high-speed serial signal from a target port and deserializing the high-speed serial signal to decode data with a preset encoding specification into original data.

It should be noted that serial communication is one of computer communication modes, and mainly plays a role in data transmission between a host and peripheral devices as well as between the host, and the serial communication has the characteristics of few transmission lines and low cost, and is mainly suitable for system communication work such as near-distance man-machine exchange, real-time monitoring and the like, and can also realize long-distance transmission by means of the existing telephone network, so that a serial communication interface is a common interface in a computer system.

It should be understood that the prior art scheme is described in fig. 3, and the Display Port receiving and applying scheme generally includes that after a Display card on a host or a notebook computer outputs a Display Port signal, a decoding chip on a Display or other Display devices receives and processes the input Display Port signal.

It should be noted that DisplayPort (DP) is a digital video interface standard developed by the alliance of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). The interface is free of authentication and authorization fund, is mainly used for connecting a video source and display equipment and also supports carrying audio, USB and other forms of data. This interface is designed to replace the conventional VGA, DVI and FPD-Link (LVDS) interfaces. The interface is backward compatible with legacy interfaces (e.g., HDMI and DVI) through active or passive adapters.

It can be understood that, the execution main body of this embodiment is defined as a test box FPGA Display Port RX, therefore, as shown in fig. 4, compared to the scheme in fig. 3, the scheme system may receive a Display Port signal output by a host, a notebook, or a camera Sensor through an FPGA of the test box, the test box may receive and decode the Display Port signal, the received image data is transmitted to a fiber gigabit network acquisition card at a host (PC) end through an optical fiber after passing through a QSFP optical module, and is finally applied to the host (PC) for processing, the scheme system may be compatible with receiving the Display Port signal output by a general host or a notebook, the Display Port signal output by the camera Sensor newly added in the field of image testing may also be received, the image data may be transmitted to the host (PC) for related testing application after being received and decoded, the host end may flexibly process the transmitted Display Port image data as needed, and Display the scheme may be more flexibly supported by the FPGA Display Port RX system in the highest Display receiving rate mode, and may support flexible processing of image data at the highest Display rate and the highest Gbps output rate of the image data, and support flexible processing system at the higher gbp/gbp-b-Port.

It is understood that a sensor (sensor) generally refers to a degummed temperature sensor, which is a detection device, and can sense information to be measured, and can convert the sensed information into an electrical signal or other information in a required form according to a certain rule, so as to meet the requirements of information transmission, processing, storage, display, recording, control, and the like. The method is the first link for realizing automatic detection and automatic control.

In a specific implementation, as shown in fig. 5, the whole process flow is: the Display Port signal output by a host, a notebook or a camera Sensor is sent to a test box FPGA, the test box FPGA receives and 8B/10B decodes high-speed serial data of the Display Port through SerDes, then descrambles and packs the received Lane data according to requirements, the decoded image data is buffered through a Buffer module after being packed, and then is transmitted to an optical fiber gigabit network acquisition card at a host (PC) end through an optical fiber gigabit network, and finally the optical fiber gigabit network card transmits the data to the host end through a PCIe bus interface for application processing.

It can be understood that, taking the execution subject test box FPGA in the present embodiment as an example, the processing flow of the entire method is the flow shown in fig. 6.

Further, in order to improve the processing effect on the serial signal, the step of acquiring the high-speed serial signal from the target port and deserializing the high-speed serial signal to decode the data with the preset encoding specification into the original data includes: acquiring a high-speed serial signal from a target port, and acquiring data with 8B/10B codes from the high-speed serial signal; the data with 8B/10B coding is decoded into uncoded original data according to the 8B/10B coding specification.

It should be noted that encoding is a process of converting information from one form or format to another form, and is also called code of computer programming language, which is called code for short. Characters, numbers or other objects are coded into numbers by a predetermined method, or information and data are converted into predetermined electric pulse signals. Codes are widely used in electronic computers, televisions, remote controls, communications, and the like. Encoding is the process by which information is converted from one form or format to another. Decoding is the inverse of encoding.

In specific implementation, an input Display Port high-speed serial signal is received and deserialized through a SerDes module of a test box FPGA, and meanwhile, input data with 8B/10B codes is decoded into uncoded original data according to an 8B/10B coding specification.

In a specific implementation, before the step of acquiring the high-speed serial signal from the target port and acquiring the data with 8B/10B coding in the high-speed serial signal, the method further includes: acquiring a transmission demand, and matching a receiving rate of a target port according to the transmission demand, wherein the receiving rate comprises: 1.62Gbps, 2.7Gbps, 4.4Gbps, 5.4Gbps, 6.0Gbps, 6.6Gbps, 8.1Gbps, 8.7Gbps, 9.0Gbps, 9.6Gbps, and 12Gbps.

Step S20: and descrambling the original data according to a preset descrambling algorithm.

Further, in order to increase the overall operating speed without interfering with the data, the descrambling the original data according to a preset descrambling algorithm includes: judging whether the original data are scrambled; if so, acquiring a descrambling algorithm corresponding to the target port, and descrambling the original data according to the descrambling algorithm; and if not, performing the step of packaging the descrambled current original data according to a preset rule through a preset Bypass strategy to generate an image data packet.

In specific implementation, the original Lane data of the Display Port decoded by 8B/10B descrambles the scrambled Lane data according to a descrambling algorithm defined in the Display Port specification, and if the original Lane data of the Display Port is not scrambled, descrambling treatment Bypass can be set to be removed, and the original data is directly output to a back-end application.

Step S30: and packaging the descrambled current original data according to a preset rule to generate an image data packet.

Further, in order to enable the data packet to run more smoothly in the execution main body of the embodiment, the step of grouping the descrambled current original data according to a preset rule to generate an image data packet includes: acquiring a data transmission coding rule corresponding to a target port and a preset image data packet length; and packing the original data according to the data transmission coding rule and the preset image data packet length to generate an image data packet.

It should be noted that the module is configured to package the received and descrambled Lane data according to a Lane data transmission encoding rule in the Display Port specification and a set image data packet length, and combine the corresponding Lane data into an image data packet, and the module may support data packages in the case of 1Lane, 2Lane, 3Lane, and 4 Lane.

Step S40: and acquiring an internal preset transmission rule, and packaging the image data packet according to the internal preset transmission rule to generate target data.

In specific implementation, in order to facilitate the internal cache transmission in the test box, the packaged image data needs to be packaged according to the internally defined data transmission rule, so that the Buffer module can perform cache transmission on the image data conveniently.

Step S50: and encapsulating the target data according to the mac protocol to generate a mac protocol encapsulation packet.

It can be understood that the image data cache control unit also includes read-write control over a DDR memory unit on the test box, writes the packaged data packet into the DDR for caching, and simultaneously reads out the data packet cached in the DDR and sends the data packet to the back-end MAC module, so as to transmit the data packet to the host end through the fiber gigabit network.

Further, in order to achieve the calling effect of the image through the storage device, before the step of encapsulating the target data according to the mac protocol to generate a mac protocol encapsulation packet, the method further includes: sending the image data packet to a target storage device for storage; and when receiving the calling instruction, sending a signal acquisition command to the target storage device to acquire the image data packet from the target storage device.

It should be noted that the image data cache control unit also includes read-write control over a DDR memory unit on the test box, writes the packaged data packet into the DDR for caching, and simultaneously reads out the data packet cached in the DDR and sends the data packet to the back-end MAC module, so as to transmit the data packet to the host end through the fiber gigabit network.

It can be understood that, the MAC packet received by the 10G Ethernet optical module is received and selected, and after being processed, the MAC packet is sent to the control command module for the MCU to execute, so as to implement communication control between the test box and the host, and meanwhile, the image data buffered by the Buffer is sent to the dedicated image acquisition card for reception through the 10G Ethernet optical module after being packaged according to the MAC protocol.

In a specific implementation, the step of obtaining an internal preset transmission rule and encapsulating the image data packet according to the internal preset transmission rule to generate target data includes: acquiring an internal preset transmission rule, wherein the internal preset transmission rule is a first-class rule and a second-class rule; when the image data packet is detected to be cached, encapsulating the image data packet according to a type of rule; and when detecting that the image data packet does not need to be cached, encapsulating the image data packet according to a second class rule.

It should be noted that the first rule and the second rule in this embodiment are only used to distinguish the two rules, and there is no sequential order. One type of rule is that in order to facilitate the internal cache transmission in the test box, packaged image data needs to be packaged according to an internally defined data transmission rule, so that a Buffer module can perform cache transmission on the image data conveniently; the second type of rule is a rule for encapsulating image data when the image data is directly processed in the next process without buffering.

Step S60: and sending the mac protocol encapsulation packet to a target image acquisition card to realize signal transmission of the target host.

It should be noted that, in this embodiment, special processing is performed on special low power consumption mode reception of the Display Port signal of the camera module, and the SerDes is controlled to switch between different stages of low power consumption and normal transmission, so that the SerDes can stably receive the Display Port signal in the low power consumption mode.

It can be understood that, the control unit is responsible for controlling the operation of the whole image test box FPGA, receiving the control command sent by the application end through the optical fiber transmission, and providing the relevant operating state in the test box for the host application end to read.

In specific implementation, the test box control command transceiver module forwards the control command analyzed by the MAC to the MCU, and feeds back the working state information of the test box collected by the MCU to the host application terminal, thereby implementing communication control between the test box and the host.

It should be noted that, the 10G Ethernet module controls to convert the data of the MAC packet into high-speed serial data and send the high-speed serial data through the optical module, and meanwhile deserializes the high-speed serial data received by the QSFP optical module to form a MAC packet, which is sent to the MAC module for analysis.

It can be understood that the test box is connected to the host end optical fiber gigabit network acquisition card through the QSFP optical module by optical fibers to realize data transmission and command communication control with the host end, and the highest data transmission between the test box and the host end through the QSFP optical module can reach 40Gbps bandwidth.

In specific implementation, the same effect can be achieved by other modes, for example, the FPGA can use different special chips or chips such as a single chip microcomputer and a DSP to respectively implement the functions of each sub-module; or QSFP optical fiber gigabit network transmission can be replaced by USB, gigabit network, thunder transmission, PCIe direct input and the like to achieve the same data transmission and communication control effects; in the interface aspect, the optical fiber port may be replaced by an interface provided in a host computer (PC) such as a USB port, a network port, a lightning port, or a PCIe jack.

In the embodiment, by receiving high-speed serial data from a preset Port, decoding the data, descrambling and packaging the decoded data, and encapsulating the data through a mac protocol and transmitting the encapsulated data to a host, display Port signals output by the host, a notebook or a camera Sensor can be received, image data can be transmitted to the host after being received and decoded for relevant test application, and the host can flexibly process the transmitted Display Port image data according to requirements; it is also more flexible and efficient in terms of image processing applications and supported rates.

Furthermore, an embodiment of the present invention further provides a computer-readable storage medium, where a program for display signal transmission is stored, and when the program for display signal transmission is executed by a processor, the steps of the method for display signal transmission are implemented as described above.
