[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on March 7, 2024, with application number 202410274917.4 and application name "A Chip System and Electronic Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of chip technology, and in particular to a chip system and electronic equipment. Background Art

[0004] In existing terminal devices, such as smartphones (including different forms such as candy-bar phones and foldable phones), tablets, and laptops, the communication between their motherboards and peripheral physical modules (such as the display chip and touch chip in the screen module) usually adopts independent connection solutions. As shown in Figure 1, the motherboard is equipped with an application processor (AP) chip and a power management integrated circuit (PMIC) chip, and the screen module side is equipped with a display driver integrated circuit (DDIC) and a touch chip. The middle shaded area is a physical adapter board. Among them, three groups of physical communication interfaces are set on the physical adapter board, including the mobile industry processor interface (MIPI) that supports communication between the AP chip and the DDIC chip, the serial peripheral interface (SPI) that supports communication between the AP chip and the touch chip, and the swire interface or I2C interface that supports communication between the PMIC chip and the DDIC.

[0005] Because each chip uses a separate physical communication interface, a large number of connection pins are required on the physical adapter board, which takes up a lot of physical space. To reduce the physical space occupied, the distance between the connection pins can be shortened. However, when the communication interfaces transmit signals simultaneously, signal crosstalk will occur, affecting the accuracy of signal transmission. Summary of the Invention

[0006] The present application provides a chip system and an electronic device to reduce the physical space occupied by connection pins in a physical adapter board and avoid signal crosstalk.

[0007] In the first aspect, an embodiment of the present application provides a chip system, comprising: a main board, a physical module and a physical adapter board; wherein, the main board comprises a plurality of first chips, which are communicatively interconnected with each other, and the physical module comprises a plurality of second chips, which are communicatively interconnected with each other; N groups of physical communication interfaces are provided in the physical adapter board, where N is a positive integer; the plurality of first chips and the plurality of second chips are respectively coupled to the N groups of physical communication interfaces, and the N groups of physical communication interfaces transmit S types of communication signals in a time-sharing manner, where S is greater than N and S is a positive integer.

[0008] It should be noted that the above-mentioned main board can be understood as the main board of an electronic device. For example, the main board of a mobile phone, the main board of a tablet computer, the main board of a smart speaker, etc., are only illustrative and not specifically limited here. The above-mentioned physical module can be understood as a chip module that communicates with the main board. For example, a screen module (including a touch chip, a display chip, etc.), a perception module (including: a gravity sensor chip, an image sensor chip, etc.), are only illustrative and not specifically limited here. The above-mentioned physical adapter board can be understood as a bridge for communication between the main board and the physical module.

[0009] In this application, because the multiple first chips in the mainboard communicate with each other, and the multiple second chips in the physical module communicate with each other, the number of communication interface groups provided in the physical adapter board is smaller than the number of communication signal types transmitted between the mainboard and the physical module. This reduces the number of connection pins in the physical adapter board. In addition, different types of communication signals are transmitted in a time-sharing manner, avoiding signal crosstalk caused by simultaneous signal transmission.

[0010] In an optional manner, multiple first chips include an application chip and a power management chip; multiple second chips include a touch chip and a display chip; N is 1; in the first time period, the physical communication interface is MIPI, and the physical communication interface transmits a display signal, which is a communication signal between the application chip and the display chip; in the second time period, the physical communication interface is SPI, and the physical communication interface transmits a touch signal, which is a communication signal between the application chip and the touch chip; or, in the second time period, the physical communication interface is a swire interface or an I2C interface, and the physical communication interface transmits a power signal, which is a communication signal between the power management chip and the display chip, and the second time period is different from the first time period.

[0011] Based on the above solution, it can be seen that the multiple first chips in the mainboard communicate and interconnect with each other, and the multiple second chips in the physical module also communicate and interconnect with each other. Therefore, a set of physical communication interfaces can be provided on the physical adapter board. Based on this, the number of connection pins on the physical adapter board can be reduced. In addition, communication between the mainboard and the physical module can be guaranteed by transmitting different types of signals at different time periods.

[0012] In an optional manner, the communication interconnection mode is a bridging mode.

[0013] In an optional manner, the bridging method includes one of the following:

[0014] Communication and interconnection are achieved through a bridge chip; or, a bridge functional unit is set in one or more chips.

[0015] In the second aspect, an embodiment of the present application provides a chip system, including: a main board, a physical module and a physical adapter board; wherein, the main board includes multiple first chips, and the multiple first chips are communicated and interconnected, and the physical module includes multiple second chips, and the multiple second chips are independent of each other; N groups of physical communication interfaces are provided in the physical adapter board, where N is a positive integer; the multiple first chips and the multiple second chips are respectively coupled to the N groups of physical communication interfaces, and the N groups of physical communication interfaces transmit S types of communication signals in time-sharing, where S is greater than N and S is a positive integer.

[0016] In this application, the multiple second chips in the physical module are independent of each other (i.e., the multiple second chips are not connected), and the multiple first chips in the mainboard are communicatively interconnected. This makes the number of communication interface groups provided in the physical adapter board smaller than the number of communication signal types transmitted between the mainboard and the physical module. Based on this, the number of connection pins in the physical adapter board can be reduced. In addition, different types of communication signals are transmitted in a time-sharing manner, avoiding signal crosstalk caused by simultaneous signal transmission.

[0017] In an optional manner, multiple first chips include an application chip and a power management chip; multiple second chips include a touch chip and a display chip; N is 2; N groups of physical communication interfaces include: SPI and a first physical communication interface; in a first time period, the first physical communication interface is MIPI, and the first physical communication interface transmits a display signal, which is a communication signal between the application chip and the display chip; in a second time period, SPI transmits a touch signal, which is a communication signal between the application chip and the touch chip; or, in the second time period, the first physical communication interface is a swire interface or an I2C interface, and the first physical communication interface transmits a power signal, which is a communication signal between the power management chip and the display chip, and the second time period is different from the first time period.

[0018] Based on the above solution, it can be seen that the multiple first chips in the mainboard communicate and interconnect with each other, so two sets of physical communication interfaces can be provided on the physical adapter board. Based on this, the number of connection pins on the physical adapter board can be reduced. In addition, communication between the mainboard and the physical module can be ensured by transmitting different types of signals at different time periods.

[0019] In an optional manner, the communication interconnection mode is a bridging mode.

[0020] In an optional manner, the bridging method includes one of the following:

[0021] Communication and interconnection are achieved through a bridge chip; or, a bridge functional unit is set in one or more chips.

[0022] In a third aspect, an embodiment of the present application provides a chip system, comprising: a main board, a physical module and a physical adapter board; wherein, the main board comprises a plurality of first chips, which are independent of each other, and the physical module comprises a plurality of second chips, which are communicatively interconnected with each other; N groups of physical communication interfaces are provided in the physical adapter board, where N is a positive integer; the plurality of first chips and the plurality of second chips are respectively coupled to the N groups of physical communication interfaces, and the N groups of physical communication interfaces transmit S types of communication signals in a time-sharing manner, where S is greater than N and S is a positive integer.

[0023] In this application, the multiple first chips in the mainboard are independent of each other (i.e., the multiple first chips are not connected), and the multiple second chips in the physical module are interconnected and communicate with each other. This makes the number of communication interface groups provided in the physical adapter board smaller than the number of types of communication signals transmitted between the mainboard and the physical module. Based on this, the number of connection pins in the physical adapter board can be reduced. In addition, different types of communication signals are transmitted in a time-sharing manner, avoiding signal crosstalk caused by simultaneous signal transmission.

[0024] In an optional manner, multiple first chips include an application chip and a power management chip; multiple second chips include a touch chip and a display chip; N is 2; N groups of physical communication interfaces include: a second physical communication interface and a third physical communication interface, the second physical communication interface is a swire interface or an I2C interface; in the first time period, the third physical communication interface is MIPI, and the third physical communication interface transmits a display signal, which is a communication signal between the application chip and the display chip; in the second time period, the third physical communication interface is SPI, and the third physical communication interface transmits a touch signal, which is a communication signal between the application chip and the touch chip; or, in the second time period, the second physical communication interface transmits a power signal, which is a communication signal between the power management chip and the display chip, and the second time period is different from the first time period.

[0025] Based on the above solution, it can be seen that the multiple second chips in the physical module communicate and interconnect with each other, so two sets of physical communication interfaces can be provided on the physical adapter board. Based on this, the number of connection pins on the physical adapter board can be reduced. In addition, communication between the mainboard and the physical module can be guaranteed by transmitting different types of signals at different time periods.

[0042] In order to make the purpose, technical solutions and advantages of this application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The specific operating methods in the method embodiments can also be applied to the device embodiments or system embodiments. In the description of this application, unless otherwise specified, "multiple" means two or more. Therefore, the implementation of the device and method can refer to each other, and the repeated parts will not be repeated.

[0043] In addition, it should be understood that, in the description of this application, words such as "first" and "second" are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0044] It should be noted that in the embodiments of the present application, "coupling" refers to an electrical connection, and the connection between two electrical components can be a direct or indirect connection between the two electrical components. For example, the connection between A and B can be either a direct connection between A and B, or an indirect connection between A and B through one or more other electrical components. For example, the connection between A and B can also be a direct connection between A and C, a direct connection between C and B, and an indirect connection between A and B through C.

[0045] As described in the background, each chip uses a separate physical communication interface, requiring a large number of connection pins on the physical adapter board, which consumes a significant amount of physical space. To reduce this physical space, the distance between the connection pins can be shortened. However, when signals are transmitted simultaneously between the various communication interfaces, crosstalk can occur, affecting the accuracy of signal transmission.

[0046] Based on this, the present application provides a chip system to reduce the physical space occupied by the connecting pins in the physical adapter board and avoid the occurrence of signal crosstalk. As shown in Figure 2A, the chip system includes: a mainboard, a physical module and a physical adapter board, wherein the mainboard may include multiple first chips, and the physical module may also include multiple second chips. Figure 2A takes the example of the mainboard including X first chips and the physical module including X second chips as an example, wherein X is an integer greater than or equal to 2. In Figure 2A, the X first chips in the mainboard communicate and interconnect with each other, and the X second chips in the physical module communicate and interconnect with each other; N groups of physical communication interfaces are provided in the physical adapter board, where N is a positive integer; multiple first chips and multiple second chips are respectively coupled to the N groups of physical communication interfaces, and the N groups of physical communication interfaces transmit S types of communication signals in time-sharing, where S is greater than N and S is a positive integer. In addition, it should be noted that when multiple first chips are communicated and interconnected, and multiple second chips are communicated and interconnected, when N is equal to 1, the physical space occupied by the connecting pins in the physical adapter board is the least, and there is no crosstalk in the signals, and the communication effect between the mainboard and the physical module is the best.

[0047] The chip system may also be shown in FIG2B , including: a mainboard, a physical module, and a physical adapter board. FIG2B takes an example in which the mainboard includes X first chips and the physical module includes X second chips, where X is an integer greater than or equal to 2. The X first chips are interconnected and communicate with each other, and the X second chips are independent of each other (i.e., there is no connection or the second chips are not interconnected); the physical adapter board is provided with N groups of physical communication interfaces, where N is a positive integer; the plurality of first chips and the plurality of second chips are respectively coupled to the N groups of physical communication interfaces, and the N groups of physical communication interfaces transmit S types of communication signals in a time-sharing manner, where S is greater than N and is a positive integer.

[0048] The chip system may also be shown in FIG2C , including: a mainboard, a physical module, and a physical adapter board. FIG2C takes an example in which the mainboard includes X first chips and the physical module includes X second chips, where X is an integer greater than or equal to 2. The X first chips are independent of each other (i.e., there is no connection or the first chips do not communicate or interconnect with each other), and the X second chips communicate and interconnect with each other; the physical adapter board is provided with N groups of physical communication interfaces, where N is a positive integer; the multiple first chips and the multiple second chips are respectively coupled to the N groups of physical communication interfaces, and the N groups of physical communication interfaces transmit S types of communication signals in a time-sharing manner, where S is greater than N and is a positive integer.

[0049] The above-mentioned main board can be understood as the main board of an electronic device. For example, the main board of a mobile phone, the main board of a tablet computer, the main board of a smart speaker, etc., are only illustrative here and not specifically limited. The above-mentioned physical module can be understood as a chip module that communicates with the main board. For example, a screen module (including a touch chip, a display chip (for example, a DDIC chip), etc.), a perception module (including: a gravity sensor chip, an image sensor chip, etc.), are only illustrative here and not specifically limited. The above-mentioned physical adapter board can be understood as a bridge for communication between the main board and the physical module. Specifically, the physical adapter board can support the transmission of different types of signals between the main board and the physical module. For example, SPI signals, MIPI signals, etc. This is only an illustrative description and does not specifically limit the type of signal.

[0050] Optionally, the motherboard may include multiple first chips, which may be of the same type or different types, and this application does not specifically limit this. For example, the motherboard may include one AP chip and one PMIC chip; or one MCU chip and two PMIC chips. This is merely an example, and does not specifically limit the number and type of chips in the motherboard. The physical module may include multiple second chips, which may be of the same type or different types, and this application does not specifically limit this. For example, the physical module may be a screen module, wherein the screen module includes one touch chip and one display chip; or the physical module includes two touch chips and one display chip. The physical module may be a sensing module, wherein the sensing module includes one gravity sensor chip, one image sensor chip, and one touch chip. This is merely an example, and does not specifically limit the number and type of chips in the physical module.

[0051] Assume that the mainboard includes three first chips, namely the first chip 1, the first chip 2 and the first chip 3, as shown in Figure 3. Among them, the first chip 1 in Figure 3 (a) communicates and interconnects with the first chip 2, and the first chip 2 communicates and interconnects with the first chip 3. The first chip 1 in Figure 3 (b) communicates and interconnects with the first chip 3, and the first chip 3 communicates and interconnects with the first chip 2. The first chip 1 in Figure 3 (c) communicates and interconnects with the first chip 3, and the first chip 1 communicates and interconnects with the first chip 2. This is not specifically limited here, only exemplified. The communication and interconnection of multiple second chips in the physical module can also be understood with reference to Figure 3, and will not be explained in detail here.

[0052] The communication interconnection method of the multiple first chips in the above-mentioned mainboard can be a bridging method. The communication interconnection method of the multiple second chips in the above-mentioned physical module can also be a bridging method. Among them, bridging can build a channel for chip communication, so that more types of signals can be transmitted between chips. Specifically, the bridging method can be to communicate and interconnect through a bridge chip, or to set a bridge function unit in one or more chips. As shown in Figure 4, the mainboard includes: 1 AP chip and 1 PMIC chip. In Figure 4 (a), a bridge chip is set between the AP chip and the PMIC chip. The bridge chip can transmit swire signals or I2C signals (for example, power signals) between the AP chip and the PMIC chip. In Figure 4 (b), a bridge function unit is set in the AP chip. The bridge function unit can transmit swire signals or I2C signals between the AP chip and the PMIC chip. In Figure 4 (c), a bridge function unit is set in the PMIC chip. The bridge function unit can transmit swire signals or I2C signals between the AP chip and the PMIC chip. A bridging function unit is usually provided in the AP chip, which can reduce the physical space occupied in the motherboard, and the integration of the bridging function unit in the AP chip can ensure data processing efficiency.

[0053] As shown in Figure 5, the screen module includes: a touch chip and a display chip. In Figure 5 (a), a bridge chip is provided between the touch chip and the display chip. The bridge chip enables SPI signal transmission between the touch chip and the display chip. In Figure 5 (b), a bridge function unit is provided in the touch chip. The bridge function unit enables SPI signal transmission between the touch chip and the display chip. In Figure 5 (c), a bridge function unit is provided in the display chip. The bridge function unit enables SPI signal transmission between the touch chip and the display chip. Generally, a bridge function unit is provided in the display chip to reduce the physical space occupied in the screen module, and the display chip integrated bridge function unit can ensure data processing efficiency.

[0054] It should be noted that the signal types transmitted between the motherboard and the physical module in different time periods may be different. By statistically analyzing the signal types transmitted in different time periods, the signal transmission pattern can be obtained. Among them, the signal transmission pattern can be understood with reference to the following Table 1. In the Active phase, the signal transmitted between the motherboard and the physical module is the display signal. In the Blank phase (that is, the blanking area of ​​the display chip), the signal transmitted between the motherboard and the physical module is the touch signal or PMIC signal or swire signal (I2C signal). Based on this, different types of signals can be transmitted between the motherboard and the physical module in different time periods.

[0055] Table 1

[0056] Specifically, the duration of the Active phase may be the working duration of the display chip (eg, DDIC chip), which is merely an example and not a limitation.

[0057] For example, four different types of signals can be transmitted between the motherboard and the screen module. These signals are display signals, touch signals, PMIC signals, and power signals. The chips in the motherboard and the screen module communicate with each other via a bridge chip, and the physical adapter board is equipped with a set of physical communication interfaces. Referring to Table 1, in the Active phase, display signals are transmitted between the motherboard and the screen module, so the physical communication interfaces in the physical adapter board transmit display signals. In the Blank phase, touch signals are transmitted between the motherboard and the screen module.

[0058] In this application, because the multiple first chips in the mainboard communicate with each other, and the multiple second chips in the physical module communicate with each other, the number of communication interface groups provided in the physical adapter board is smaller than the number of communication signal types transmitted between the chips in the mainboard and the chips in the physical module. This reduces the number of connection pins in the physical adapter board. In addition, different types of communication signals are transmitted in a time-sharing manner, avoiding signal crosstalk caused by simultaneous signal transmission.

[0059] In order to better illustrate the solution of this application, the following situations are explained, specifically as follows:

[0060] Case 1: Multiple first chips in the mainboard communicate and interconnect, and multiple second chips in the physical module communicate and interconnect

[0061] Among them, the multiple first chips include application chips (such as AP chips) and power management chips (such as PMIC chips); the multiple second chips include touch chips and display chips (for example, DDIC chips); N is 1; in the first time period (that is, the Active stage in Table 1 above), the physical communication interface is MIPI, and the physical communication interface transmits a display signal, which is a communication signal between the application chip and the display chip; in the second time period (that is, the Blank stage in Table 1 above), the physical communication interface is SPI, and the physical communication interface transmits a touch signal, which is a communication signal between the application chip and the touch chip; or, in the second time period, the physical communication interface is a swire interface or an I2C interface, and the physical communication interface transmits a power signal, which is a communication signal between the power management chip and the display chip. The second time period is different from the first time period.

[0062] As shown in Figure 6A, the motherboard includes an AP chip and a PMIC chip, and the physical module is a screen module, which includes a touch chip and a DDIC chip. The AP chip is equipped with a bridging function unit, which enables Swire signals or I2C signals (illustrated as power signals in Figure 6A) to be transmitted between the AP chip and the PMIC chip. The DDIC chip is equipped with a bridging function unit, which enables SPI signals to be transmitted between the touch chip and the DDIC chip. The motherboard and the screen module transmit different types of signals in a time-sharing manner via a set of physical communication interfaces on the physical adapter board. In the first time period (i.e., the Active phase in Table 1 above), the physical communication interface is MIPI, and the AP chip transmits display signals to the DDIC chip via the physical communication interface. In the second time period (i.e., the Blank phase in Table 1 above), the physical communication interface is SPI, and the AP chip transmits touch signals to the touch chip via the physical communication interface. Alternatively, in the second time period, the physical communication interface is a Swire interface or an I2C interface, and the PMIC chip transmits power signals via the physical communication interface.

[0063] Based on the above solution, it can be seen that the multiple first chips in the mainboard communicate and interconnect with each other, and the multiple second chips in the physical module also communicate and interconnect with each other. Therefore, a set of physical communication interfaces can be provided on the physical adapter board. Based on this, the number of connection pins on the physical adapter board can be reduced. In addition, communication between the mainboard and the physical module can be guaranteed by transmitting different types of signals at different time periods.

[0064] Case 2: Multiple first chips in the mainboard communicate and interconnect, and multiple second chips in the physical module are independent of each other

[0065] Among them, the multiple first chips include application chips and power management chips; the multiple second chips include touch chips and display chips; N is 2; N groups of physical communication interfaces include: SPI and a first physical communication interface; in the first time period, the first physical communication interface is MIPI, and the first physical communication interface transmits a display signal, which is a communication signal between the application chip and the display chip; in the second time period, SPI transmits a touch signal, which is a communication signal between the application chip and the touch chip; or, in the second time period, the first physical communication interface is a swire interface or an I2C interface, and the first physical communication interface transmits a power signal, which is a communication signal between the power management chip and the display chip, and the second time period is different from the first time period.

[0066] As shown in Figure 6B, the mainboard includes: an AP chip and a PMIC chip, and the physical module is a screen module, wherein the screen module includes: a touch chip and a DDIC chip. The AP chip is provided with a bridging function unit, based on which a swire signal or an I2C signal can be transmitted between the AP chip and the PMIC chip (illustrated as a power signal in Figure 6B). The mainboard and the screen module transmit different types of signals in a time-sharing manner through two sets of physical communication interfaces in the physical adapter board. In the first time period (i.e., the Active phase in Table 1 above), the first physical communication interface is MIPI, and the AP chip transmits display signals to the DDIC chip through the first physical communication interface; in the second time period (i.e., the Blank phase in Table 1 above), the AP chip transmits touch signals to the touch chip through SPI; alternatively, in the second time period, the first physical communication interface is a swire interface or an I2C interface, and the PMIC chip transmits power signals through the first physical communication interface.

[0067] Based on the above solution, it can be seen that the multiple first chips in the mainboard communicate and interconnect with each other, so two sets of physical communication interfaces can be provided on the physical adapter board. Based on this, the number of connection pins on the physical adapter board can be reduced. In addition, communication between the mainboard and the physical module can be ensured by transmitting different types of signals at different time periods.

[0068] Case 3: Multiple second chips in the physical module communicate and interconnect, and multiple first chips in the mainboard are independent of each other

[0069] Among them, the multiple first chips include application chips and power management chips; the multiple second chips include touch chips and display chips; N is 2; N groups of physical communication interfaces include: a second physical communication interface and a third physical communication interface, the second physical communication interface is a swire interface or an I2C interface; in the first time period, the third physical communication interface is MIPI, and the third physical communication interface transmits a display signal, which is a communication signal between the application chip and the display chip; in the second time period, the third physical communication interface is SPI, and the third physical communication interface transmits a touch signal, which is a communication signal between the application chip and the touch chip; or, in the second time period, the second physical communication interface transmits a power signal, which is a communication signal between the power management chip and the display chip, and the second time period is different from the first time period.

[0070] As shown in Figure 6C, the motherboard includes an AP chip and a PMIC chip, and the physical module is a screen module, wherein the screen module includes a touch chip and a DDIC chip. The DDIC chip is provided with a bridge function unit, based on which SPI signals can be transmitted between the touch chip and the DDIC chip. The motherboard and the screen module transmit different types of signals in a time-sharing manner through two sets of physical communication interfaces in the physical adapter board. In the first time period (i.e., the Active phase in Table 1 above), the third physical communication interface is MIPI, and the AP chip transmits display signals to the DDIC chip via the third physical communication interface; in the second time period (i.e., the Blank phase in Table 1 above), the PMIC chip transmits power signals via the second physical communication interface; alternatively, in the second time period, the third physical communication interface is SPI, and the AP chip transmits touch signals to the touch chip via SPI.

[0071] Based on the above solution, it can be seen that the multiple second chips in the physical module communicate and interconnect with each other, so two sets of physical communication interfaces can be provided on the physical adapter board. Based on this, the number of connection pins on the physical adapter board can be reduced. In addition, communication between the mainboard and the physical module can be guaranteed by transmitting different types of signals at different time periods.
