In the prior art, in order to speed up the startup speed of the camera and the image display speed, a faster startup chip is usually used to replace a slower startup chip to first control the startup of the camera and run the display function of the camera image. After the slower startup chip completes the startup, the slower startup chip takes over the processing function of the camera image.

[0004] However, this processing method may cause residual current to be generated in the slow-starting chip that has not yet been powered on, thereby causing the slow-starting chip to fail to start. Summary of the invention

[0005] Based on the above defects and shortcomings of the prior art, the present application proposes a chip startup method and related devices, which can solve the problem that the chip with slow startup in the existing image processing system cannot be started because a certain residual current has been generated inside it before power-on.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0033] Application Overview

[0034] The startup of the camera in the smart device and the processing of the captured image (such as image display) are generally completed by chips with high computing processing capabilities (such as system on chip (SoC)). However, the startup speed of such chips is slow, which affects the startup speed of the camera, image display speed, etc.

[0035] In order to meet the requirements of fast camera startup and timely image display in smart devices, a chip with faster startup (such as a microcontroller unit (MCU)) can be used to control the camera to start in advance and control the display of camera images. After the chip with slower startup is started, the camera control link is switched, and the chip with slower startup but stronger computing and processing capabilities takes over the camera image processing function.

[0036] As smart devices have higher and higher requirements for chip security levels, some system-level chips are equipped with residual current detection mechanisms. Before such chips are powered on, if current is detected inside the chip, the chip will not start for safety reasons. For the aforementioned solutions for achieving fast camera startup and timely image display, it may cause the chip that starts slowly to have a certain amount of residual current inside before powering on, causing the chip to fail to start.

[0037] For example, Figure 1 As shown, after the first chip that starts faster starts, it can control the camera and deserializer to start, and then the first chip controls the deserializer to output the image data collected by the camera through the camera serial interface (CSI). At this time, the second chip that starts slower may not be powered on, but the CSI of the second chip and the CSI of the deserializer will be turned on, causing current to flow into the second chip, so that the second chip has a certain residual current inside before powering on, and finally the second chip fails to start. This situation can also be called a series current or leakage current problem between circuit components.

[0038] In order to solve the above technical problems, in an embodiment of the present application, for the second chip in the image processing system that starts slower, before it is powered on, the first chip in the image processing system that starts slower can be used to prohibit the image data collected by the camera in the image processing system and received by the deserializer from being input into the second chip, thereby solving the problem that the port of the second chip for inputting image data (such as CSI) and the port of the deserializer for outputting image data (such as CSI) are turned on due to the transmission of image data, resulting in residual current generated inside the second chip before it is powered on, ultimately causing the second chip to fail to start.

[0039] Exemplary Methods

[0040] An embodiment of the present application provides a chip startup method, which is applied to intelligent devices including an image processing system, such as intelligent driving vehicles, drones, robots, etc.

[0041] like Figure 2 As shown, the image processing system may include: a camera, a deserializer, a first chip, a second chip and other hardware structures. Among them, the startup time of the first chip is shorter than the startup time of the second chip, that is, the first chip starts faster and the second chip starts slower, but the computing processing capability of the second chip is higher than that of the first chip. In addition, a residual current detection mechanism is provided in the second chip.

[0042] The camera is connected to the deserializer, and the first chip and the second chip are connected to the deserializer respectively.

[0043] The camera is used to collect image data and send serial image data to the deserializer.

[0044] The deserializer is used to convert the received serial image data into parallel image data, and at least send the parallel image data to the second chip so that the second chip performs subsequent image processing. Figure 2 As shown, the deserializer can transmit the parallel image data to the second chip through the CSI.

[0045] Optionally, the deserializer may also send the parallel image data to the first chip so that the first chip can control the display of the camera image before the second chip completes startup.

[0046] Alternatively, the deserializer may also send the parallel image data to the third chip so that the third chip can control the display of the camera image before the second chip completes the startup. Figure 3 As shown, the deserializer may send the parallel image data to the second chip via CSI_1 and may send the parallel image data to the third chip via CSI_2.

[0047] In the case where the smart device is a smart driving vehicle, the first chip and the second chip may be chips in the smart driving control domain, and the second chip may be the main control chip in the smart driving control domain. Since smart driving has high requirements for data processing speed and accuracy, the second chip needs to be a chip with strong computing and processing capabilities, and therefore the internal system of the second chip is more complex, resulting in a slower startup speed. The third chip can be a chip that starts faster in the smart cockpit control domain, or it can be a system-level chip. The smart cockpit control logic is relatively simple, so there is no need for a system-level chip with too high computing and processing capabilities, and its internal system is also simpler than the second chip, so its startup speed is faster, and the smart cockpit control domain has lower requirements for the chip's safety level, and there is no need to set a residual current detection mechanism inside it, so before the second chip is powered on, the display of the camera image can be controlled by the third chip that starts faster. Among them, the first chip can be a power supply main control chip in a smart device, such as a chip that is mainly used to control the power supply of each chip in a smart device.

[0048] The first chip can control the camera and the deserializer to start, such as controlling the camera and the deserializer to power on, initialize, etc. The first chip and the second chip can both control the deserializer to output the image data collected by the camera. Optionally, the second chip can also control the camera and the deserializer to start (not shown in the figure). For example, in some cases, such as the failure of the first chip, the second chip may start before the first chip. At this time, the second chip can control the camera and the deserializer to start. Among them, the second chip can monitor whether the first chip is started.

[0049] Among them, the execution subject of the chip startup method provided in the embodiment of the present application can specifically be the aforementioned first chip.

[0050] The method is described in detail below through some embodiments. The following embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0051] like Figure 4 As shown, the method may include steps 401 to 402, as described below:

[0052] Step 401: When the first chip is started up, the deserializer is controlled to be powered on, and image data collected by the camera and received by the deserializer is prohibited from being input to the second chip.

[0053] In the embodiment of the present application, after the smart device is powered on, the image processing system starts to be powered on, and the first chip in the image processing system can be started at a faster speed. After that, the first chip can be enabled through the enable port (Enable port, i.e., Figure 2The EN port in the first chip controls the deserializer to enable, thereby powering on the deserializer. Of course, the first chip can also control the camera to start through the camera's use port so that the camera can collect image data.

[0054] After the camera is started, the collected image data can be sent to the deserializer. In order to avoid the port of the second chip used to input image data and the port of the deserializer used to output image data from being connected before the second chip is powered on, the first chip can prohibit the image data collected by the camera in the image processing system and received by the deserializer from being input into the second chip in the image processing system. In this way, the current will not be backflowed into the second chip due to the conduction between the two ports, making the second chip unable to start.

[0055] Step 402: when it is detected that the second chip is powered on, the image data collected by the camera and received by the deserializer is allowed to be input into the second chip.

[0056] In the embodiment of the present application, the first chip can detect whether the second chip is powered on. After the second chip is successfully powered on, the residual current detection mechanism will not be triggered, and the second chip can be successfully started. Therefore, at this time, the first chip can control the image data collected by the camera received by the deserializer to be input to the second chip. Since the second chip needs to be initialized after powering on, image processing cannot be performed during this period. Therefore, at this time, the deserializer can send the image data to Figure 2 The first chip in or Figure 3 The third chip in the display is used to display the camera image.

[0057] In some optional embodiments, “forbidding the image data collected by the camera and received by the deserializer from being input into the second chip” in step 401 may include:

[0058] Step A1: prohibiting the deserializer from outputting the image data collected by the camera.

[0059] In an embodiment of the present application, the first chip can prohibit the image data collected by the camera in the image processing system and received by the deserializer from being input into the second chip in the image processing system by prohibiting the deserializer from outputting the image data collected by the camera.

[0060] Accordingly, in step 402, “allowing the image data collected by the camera and received by the deserializer to be input into the second chip” may include:

[0061] Step B1: Allow the deserializer to output image data collected by the camera.

[0062] After the first chip detects that the second chip is powered on, the deserializer may be allowed to output the image data collected by the camera, thereby transmitting the image data to the second chip.

[0063] Optionally, step A1: prohibiting the deserializer from outputting image data collected by the camera may include: after the deserializer is powered on, prohibiting the deserializer from initializing so as to prohibit the deserializer from outputting image data.

[0064] After the deserializer is powered on, it needs to be initialized. Only after the initialization is completed can the image data collected by the camera be output externally. Therefore, in the embodiment of the present application, the first chip can control the initialization of the deserializer, temporarily prohibit the deserializer from entering the initialization process, thereby prohibiting the deserializer from outputting image data. After the second chip is powered on, the deserializer is allowed to initialize, so that the deserializer that has completed the initialization can output the image data collected by the camera externally.

[0065] Optionally, a PWDNB port is provided on the deserializer for initializing and controlling the deserializer, and can be configured: when the PWDNB port is in a low level state, it indicates that the deserializer initialization is prohibited; when the PWDNB port is in a high level state, it indicates that the deserializer can be initialized. Therefore, the first chip can prohibit the deserializer initialization by controlling the PWDNB port of the deserializer to be in a low level state. After the second chip is powered on, the PWDNB port is pulled high again, that is, the PWDNB port is controlled to be in a high level state, so as to initialize the deserializer.

[0066] Optionally, in the embodiment of the present application, a switch module may be provided between the first port of the deserializer and the second port of the second chip, that is, the switch module is connected to the first port of the deserializer and the second port of the second chip respectively. Figure 5 and Figure 6 As shown, a switch module is provided between the CSI of the deserializer and the CSI of the second chip. In addition, the switch module is also connected to the first chip, and the first chip can control the opening and closing of the switch module.

[0067] The first port of the deserializer described here is used to output image data collected by the camera, and the second port of the second chip described here is used to input image data collected by the camera.

[0068] In step 401, “prohibiting the image data collected by the camera and received by the deserializer from being input into the second chip” may include:

[0069] Step A2: Control the switch module to be in the disconnected state.

[0070] In the embodiment of the present application, a switch module can be set between the first port of the deserializer and the second port of the second chip, and then the first chip controls the on and off of the switch module. After the first chip is started, the switch module can be controlled to be in an off state, so that the connection circuit between the deserializer and the second chip is disconnected, so as to prohibit the image data output by the deserializer from being input to the second chip.

[0071] Accordingly, in step 402, “allowing the image data collected by the camera and received by the deserializer to be input into the second chip” may include:

[0072] Step B1: Control the switch module to be in a closed state.

[0073] After the first chip detects that the second chip is powered on, the switch module can be controlled to be in a closed state, so that the connection circuit between the deserializer and the second chip is turned on, thereby transmitting the image data collected by the camera output by the deserializer to the second chip.

[0074] It should be noted that the type of the switch module can also be selected according to actual needs, and the embodiment of the present application does not limit this. In addition, in addition to setting a switch module between the first port of the deserializer and the second port of the second chip, the switch module in this case is still electrically connected to the first chip, so that the first chip can control the on-off state of the switch module, especially before the second chip is powered on, by controlling the switch module to be in an off state, the image data output by the deserializer is prohibited from being input to the second chip.

[0075] In some optional embodiments, when the first chip completes startup, the chip startup method may further include:

[0076] The state of the input / output port of the second chip is obtained; when it is detected that the state of the input / output port of the second chip is at a high level, it is determined that the second chip is powered on.

[0077] The first chip is connected to the input and output ports of the second chip.

[0078] By detecting the state of the input and output ports of the second chip, it can be determined whether the second chip is powered on. Among them, it can be configured that: the input and output ports are in a low level state, indicating that they are not powered on; the input and output ports are in a high level state, indicating that they are powered on. Therefore, if the input and output ports of the second chip are in a low level state, it can be determined that the second chip is not powered on; if the input and output ports of the second chip are in a high level state, it can be determined that the second chip is powered on.

[0079] Alternatively, if Figure 2 and Figure 3 as well as Figure 5 and Figure 6As shown, the input / output port may be a general purpose input / output port (GPIO). Both the first chip and the second chip are provided with GPIO ports, and the GPIO ports of the two chips are connected, so the first chip can monitor the status of the GPIO port of the second chip.

[0080] In some optional embodiments, after disabling the deserializer from outputting an image, the chip startup method may further include: controlling the second chip to power on.

[0081] In the embodiment of the present application, the first chip can control the power-on of the second chip, for example, Figure 2 and Figure 3 as well as Figure 5 and Figure 6 As shown, the GPIO port of the first chip is connected to the EN port of the second chip, and the first chip can control the EN port of the second chip through the GPIO port to control the power-on timing of the second chip.

[0082] Specifically, the first chip can control the second chip to start powering on after prohibiting the deserializer from outputting the image collected by the camera, so that each component can be powered on in order. By reasonably controlling the power-on timing of each component, the problem that the second chip cannot start due to serial power can be better solved.

[0083] It is understandable that the power-on of the second chip may not be controlled by the first chip. After the image processing system is powered on, it can be powered directly by the power supply of the second chip. In this case, before prohibiting the deserializer from outputting the image captured by the camera, the first chip can first detect whether the second chip is powered on. If the second chip is not powered on, the step of "prohibiting the deserializer from outputting the image captured by the camera" is executed; if it is detected that the second chip is powered on, the deserializer can be directly controlled to output the image captured by the camera.

[0084] In some optional embodiments, after the deserializer is prohibited from outputting the image data collected by the camera, the chip startup method may further include:

[0085] If the second chip is not detected to be powered on within the detection time threshold, the image processing system is controlled to be powered on again.

[0086] In the embodiment of the present application, a detection time threshold can be set for the detection time of the second chip power-on. If the second chip power-on is not detected within the detection time threshold, it means that the second chip power-on time has timed out, and there may be a certain fault. At this time, the image processing system can be powered on again, and the steps in the chip startup method provided in the embodiment of the present application can be re-executed.

[0087] When the image processing system is repeatedly powered on for a number of times reaching a threshold, the power-on can be stopped and an alarm message can be output.

[0088] Among them, the above-mentioned detection time threshold can be set according to actual needs, and the embodiments of the present application do not specifically limit this.

[0089] Optionally, in an embodiment of the present application, within a detection time threshold, the first chip may periodically detect whether the second chip is powered on.

[0090] In some optional embodiments, the first chip is a micro control unit (MCU), and the second chip is a system-on-chip (SoC).

[0091] MCU chips are usually specially designed for embedded systems, with relatively simple functions and fewer integrated hardware resources. Therefore, their initialization process is relatively simple and fast. The initialization of SoC chips may involve multiple steps such as initialization of multiple processor cores, memory configuration, and peripheral initialization. Therefore, more time is required to complete the initialization process. Therefore, the initialization of MCU chips is usually faster than that of SoC chips, which makes the startup speed of MCU chips faster than that of SoC chips. Therefore, when the MCU chip completes initialization, it can enable the camera and deserializer one step earlier than the SoC chip, complete the startup of the camera and deserializer, and complete the display of the camera image.

[0092] Optionally, the first chip may also be a Field Programmable Gate Array (FPGA) chip.

[0093] To summarize, the chip startup method provided in the embodiment of the present application can control the deserializer to prohibit the external output of image data collected by the camera by starting the first chip faster, thereby solving the problem that before the second chip is powered on, its port for inputting image data and the port for outputting image data of the deserializer are turned on due to the transmission of image data, resulting in residual current generated inside the second chip before it is powered on, which ultimately causes the second chip to fail to start.

[0095] Accordingly, the embodiment of the present application also provides a chip startup device, which is applied to an intelligent device including an image processing system, such as an intelligent driving vehicle, a drone, a robot, etc. The image processing system may include: a camera, a deserializer, a first chip, a second chip and other hardware structures.

[0096] The camera is connected to the deserializer, and the first chip and the second chip are connected to the deserializer respectively.

[0097] The startup time of the first chip is shorter than that of the second chip, that is, the first chip starts faster and the second chip starts slower, but the computing processing capability of the second chip is higher than that of the first chip. In addition, a residual current detection mechanism is provided in the second chip.
