Detailed Description
In order to make the objects, features and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
DSI is used for image output, such as a screen of electronic equipment, and CSI is used for image access, such as an image sensor and a camera; in the related art, the DSI and the CSI are two independent and completely unrelated interfaces, and the implementation needs to configure two D-PHYs (one physical layer) respectively, which is expensive.
Furthermore, since DSI is used for display and CSI is used for transmitting image data to other electronic devices or system on chip (SoC), both are not generally used at the same time, two different modules (IPs) are required to support both protocols, which may cause duplication of functions and waste of resources.
Based on the defects in the related art, the present disclosure provides a data processing method, which enables one module (interface) to simultaneously support two protocols, namely DSI and CSI, so as to solve some or all of the above technical problems.
Fig. 1 shows an alternative flow chart of a data processing method provided in an embodiment of the present disclosure, which will be described according to various steps.
The data processing method provided by the embodiment of the disclosure is applied to an image output module, wherein the image output module is used for displaying data or transmitting image data; specifically, the image output module may output data of a DSI protocol when used for displaying data, and may output data of a CSI protocol when used for transmitting image data.
Step S201, determining a protocol corresponding to data to be generated.
In some embodiments, an execution carrier (hereinafter referred to as an execution carrier) of the data processing method confirms a protocol corresponding to data to be generated based on indication information stored in a register. The indication information is used to indicate a protocol corresponding to data to be generated, and may be at least one of a full chinese name, an english full pinyin, or an abbreviation of the protocol, or may be a symbol indicating the protocol, such as a DSI protocol of 0, a CSI protocol of 1, a DSI protocol of a, a CSI protocol of b, and the like, which is not specifically limited in this disclosure.
In some embodiments, the protocol includes a display serial interface protocol or a camera serial interface protocol, and the device generates the data to be generated corresponding to the protocol after confirming the protocol.
Step S202, based on the time sequence control signal and the protocol, outputting the data to be generated from the only target port of the image output module.
In some embodiments, the timing control signal includes a control signal in a vertical direction and a control signal in a horizontal direction, the vertical direction including a vertical synchronization sub-signal, a vertical synchronization sub-signal leading shoulder, and a vertical resolution sub-signal; the horizontal direction includes a horizontal synchronization sub-signal, a horizontal synchronization sub-signal front shoulder, and a horizontal resolution sub-signal.
In some embodiments, the data to be generated comprises at least one data packet; unlike the related art, the at least one data packet is output from a unique destination port included in the image output module. The specific use of the image output module or the protocol of the data may be determined according to the indication information stored in the register, it should be noted that the use of the image output module is not fixed, and switching may be performed based on the indication information, such as switching from display data to transmission image data, or switching from transmission image data to display data; accordingly, the protocol of the output data is switched from the DSI protocol to the CSI protocol or from the CSI protocol to the DSI protocol.
In some embodiments, the execution carrier outputs the data to be generated based on the target port. Optionally, the execution carrier sends the data to be generated to a bottom layer Protocol layer (Low Level Protocol), and sends the data to be generated to the target port through the bottom layer Protocol layer; wherein the destination port is a physical port.
Therefore, by the data processing method provided by the embodiment of the disclosure, the DSI protocol and the CSI protocol that need to be supported by two modules in the related art are optimized as one module, and when the output data are different, the corresponding protocol of the data can be confirmed based on the indication information in the register, so that the function of the module for outputting the DSI protocol data or the CSI protocol data is realized, and the function repetition and the resource waste are avoided.

In some embodiments, as shown in fig. 3, the data processing method provided by the embodiments of the present disclosure is applied to an image output module, which is used for displaying data or transmitting image data; specifically, the image output module may output data of a DSI protocol when used for displaying data, and may output data of a CSI protocol when used for transmitting image data.
Step S301, confirming a protocol corresponding to the data to be generated.
In some embodiments, the execution carrier of the data processing method confirms the protocol corresponding to the data to be generated based on the indication information stored in the register. The indication information is used to indicate a protocol corresponding to data to be generated, and may be at least one of a full chinese name, an english full pinyin, or an abbreviation of the protocol, or may be a symbol indicating the protocol, such as a DSI protocol of 0, a CSI protocol of 1, a DSI protocol of a, a CSI protocol of b, and the like, which is not specifically limited in this disclosure.
In some embodiments, the protocol includes a display serial interface protocol or a camera serial interface protocol, and after the carrier confirmation protocol is executed, if the protocol is a DSI protocol, step S302 is executed, or if the protocol is a CSI protocol, step S303 is executed.
Step S302, outputting data to be generated corresponding to the DSI protocol based on the time sequence control signal.
In some embodiments, as shown in fig. 4 and 5, if the protocol is DSI, the data to be generated includes a vertical data packet and a horizontal data packet; the Vertical DATA packets comprise a Vertical synchronization Start DATA packet (VSS), a Vertical synchronization End DATA packet (VSE), and a second DATA packet (DT and DATA in the Vertical DATA packets); the horizontal packets include a horizontal synchronization start packet (HSS), a horizontal synchronization end packet (HVSE), and a first packet (DT and DATA in the horizontal packet). The vertical direction (vtotal) of the time sequence control signal comprises a vertical synchronization sub-signal (vsync), a vertical synchronization sub-signal front shoulder (vbp), a vertical resolution sub-signal (vactive) and a vertical synchronization sub-signal back shoulder (vfp); the horizontal direction (htotal) includes a horizontal synchronization sub-signal (hsync), a horizontal synchronization sub-signal front shoulder (hbp), a horizontal resolution sub-signal (reactive), and a vertical synchronization sub-signal back shoulder (hfp).
In specific implementation, as shown in fig. 4 and 5, the execution carrier generates a vertical synchronization start packet (VSS) in response to receiving the vertical synchronization sub-signal (vsync); generating a vertical synchronization end packet (VSE) in response to receiving the vertical synchronization sub-signal shoulder (vbp); in response to receiving a vertical resolution sub-signal (vactive), generating a second DATA packet (DT and DATA in a vertical DATA packet) of a resolution corresponding to the vertical resolution sub-signal; in response to receiving the horizontal synchronization sub-signal (hsync), generating a horizontal synchronization start packet (HSS); generating a horizontal synchronization end packet (HSE) in response to receiving the horizontal synchronization sub-signal shoulder (hbp); in response to receiving the horizontal resolution sub-signal (active), a first DATA packet (DT and DATA in a horizontal DATA packet) of a resolution corresponding to the horizontal resolution sub-signal is generated.
In some embodiments, the execution carrier further outputs the vertical synchronization start packet, the vertical synchronization end packet, the horizontal synchronization start packet, the horizontal synchronization end packet, and the first and second packets corresponding to data based on a destination port. Optionally, the execution carrier may output the generated data packet based on the destination port after generating the data packet, or may output the data packet based on the destination port after all the data packets are generated and packed. As shown in fig. 2, the data packet needs to pass through the bottom protocol layer and then be output by the destination port.
Step S303, outputting to-be-generated data corresponding to the CSI protocol based on the timing control signal.
In some embodiments, as shown in fig. 4 and 5, if the protocol is CSI, the data to be generated includes a frame data packet and a row data packet; the Frame DATA packets comprise a Frame synchronization Start DATA packet (FS), a Frame synchronization End DATA packet (FE) and a third DATA packet (DT and DATA in the Frame DATA packets); the row DATA packets include a row synchronization start DATA packet (LS), a row synchronization end DATA packet (LE), and a fourth DATA packet (DT and DATA in the row DATA packet). The vertical direction of the time sequence control signal comprises a vertical synchronization sub-signal (vsync), a vertical synchronization sub-signal front shoulder (vbp), a vertical resolution sub-signal (vactive) and a vertical synchronization sub-signal back shoulder (vfp); the horizontal direction includes a horizontal sync sub-signal (hsync), a horizontal sync sub-signal front shoulder (hbp), a horizontal resolution sub-signal (reactive), and a vertical sync sub-signal back shoulder (hfp).
In a specific implementation, as shown in fig. 4 and 5, the execution bearer generates a frame synchronization end packet (FE) in response to receiving the vertical synchronization sub-signal (vsync); generating a frame sync start packet (FS) in response to receiving the vertical sync sub-signal shoulder (vbp); in response to receiving a vertical resolution sub-signal (vactive), generating a third DATA packet (DT and DATA in a frame DATA packet) of a resolution corresponding to said vertical resolution sub-signal; generating a line synchronization end packet (LE) in response to receiving the horizontal synchronization sub-signal (hsync); generating a line sync start data packet (LS) in response to receiving the horizontal sync sub-signal shoulder (hbp); in response to receiving the horizontal resolution sub-signal (active), a fourth DATA packet (DT and DATA in the horizontal DATA packet) of a resolution corresponding to the horizontal resolution sub-signal is generated.
In some embodiments, the execution carrier further outputs the frame synchronization start packet, the frame synchronization end packet, the line synchronization start packet, the line synchronization end packet, and the third packet and the fourth packet corresponding to data based on a destination port. Optionally, the execution carrier may output the generated data packet based on the destination port after generating the data packet, or may output the data packet based on the destination port after all the data packets are generated and packed. As shown in fig. 2, the data packet needs to pass through the bottom protocol layer and then be output by the destination port.
Therefore, by the data processing method provided by the embodiment of the disclosure, the DSI protocol and the CSI protocol which need to be supported by two modules respectively in the related art are optimized to be supported by one module, and the function of the module for outputting the DSI protocol data or the CSI protocol data is realized based on the indication information confirmation protocol in the register, thereby avoiding the function repetition and the resource waste.
