Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic structural diagram of an expansion device of an electronic product according to an embodiment of the present invention is shown, where the expansion device includes: the system comprises a control module 1, a bus gating module 2 and at least one expansion interface 3; at least one expansion interface 3 is connected with the control module 1; the bus gating module 2 is connected between the control module 1 and at least one expansion interface 3; the control module 1 is configured to:
detecting whether the expansion interface 3 has the number of pins and the pins are set to be accessed by the expansion module consistent with the expansion interface 3;
if detecting that an expansion module is accessed on the expansion interface 3, reading module information of the expansion module; the module information is pre-stored in the expansion module;
and controlling the bus gating module to gate the corresponding bus of the electronic product for the expansion interface according to the module information, and performing initialization configuration on the expansion module.
In the embodiment of the present invention, by setting the bus gating module 2, the control module 1, and at least one expansion interface 3, when an electronic product needs to add a function required by a user, the user can access an expansion module capable of implementing a corresponding function to the expansion interface 3, and when the control module 1 detects that the expansion interface 3 has the expansion module access, the control module reads module information related to the expansion module; then controlling the bus gating module 2 to gate the corresponding bus of the electronic product for the expansion interface 3 according to the module information; and finally, performing initialization configuration on the expansion module according to the module information, so that the expansion module can normally work. From the above analysis, it can be seen that the electronic product can have function expansion by the above technical solution of the present invention, so that the required functions can be flexibly increased according to the requirements of the user, thereby enabling the application of the electronic product to be wider.
As an example, the module information includes module type information of the expansion module, bus type information of the expansion module; the control module is specifically configured to:
controlling the bus gating module to gate a corresponding bus of the electronic product for the expansion interface according to the bus type information;
and performing initialization configuration on the expansion module according to the module type information.
It is understood that the number of pins and the pin arrangement of the expansion module for accessing the expansion interface 3 are the same as those of the expansion interface 3. As an example, the bus may include two types of high-speed bus and low-speed serial bus, and both the high-speed bus and the low-speed serial bus of the electronic product are connected to the gating module. The high-speed bus of the electronic product may be of various types, for example, a PCIE bus, a SATA bus, a USXGMII bus, and the like. The low-speed serial bus of the electronic product may also be various, for example, a UART bus, an IIC bus, an I2S bus, an SPI bus, an SMI bus, and other bus types. The control module 1 controls the bus gating module 2 to gate the corresponding bus for the expansion interface 3 according to the bus type information read to the expansion module, for example, if the bus type information read by the control module 1 for the expansion module is a PCIE bus, the control module 2 controls the expansion interface 3 inserted into the expansion module to gate the PCIE bus. Of course, the bus may also include only the high speed bus type described above, or a low speed serial bus type, etc.
It should be noted that the module type information is used to indicate a module type of the extension module, for example, to indicate that the extension module is a WIFI module or a bluetooth module. The module type information may be an ID code including an extension module, and the module type of the extension module may be identified by the ID code, for example, if the ID code is 01, the extension module is identified as a WIFI module, and if the ID code is 02, the extension module is identified as a bluetooth module. In addition, the control module 1 is preset with the content of the initialization configuration for the corresponding expansion module. When the control module 1 reads the module type information of the extension module, the control module 1 performs initialization configuration on the extension module according to the preset initialization configuration content corresponding to the extension module, so that the extension module can normally work. The initialization configuration content preset by the control module 1 may include corresponding initialization configuration parameters and/or initialization programs, and the control module 1 may perform initialization configuration on the extension module according to an existing initialization configuration mode.
It is to be understood that the module information may also include only type information (e.g., module ID) of the module. Of course, the module information may also include other information contents, as long as the information contents included in the module information enable the control module to identify the type and bus type of each expansion module, which is not specifically limited herein.
Specifically, before the initial configuration of the extension module, the control module 1 is further configured to:
the control module 1 itself is reset.
In this embodiment, before the initialization configuration of the expansion module, the control module 1 itself may be reset, so that the initialization configuration of the expansion module can be better performed subsequently.
Further, the number of the expansion interfaces 3 is at least two, and the number of pins and the pin setting of each expansion interface 3 are the same.
In this embodiment, at least two expansion interfaces 3 are provided, and the number of pins and the pin setting of each expansion interface 3 are the same, so that different expansion modules can be arbitrarily accessed into the expansion interfaces 3, and it is not necessary to configure a specific expansion interface 3 for each expansion module, thereby making the use of the expansion interfaces 3 more general and flexible, and further enabling a user to add various expansion modules for electronic products more flexibly. It is understood that the pin number and the pin arrangement of each expansion module are the same as those of the expansion interface 3.
In the above embodiment, referring to fig. 2, the pins of each of the expansion interfaces 3 include a bus pin, a detection pin, a power supply pin, a control bus pin, and a ground pin; the low-speed serial bus gating unit 21 is connected between the control module 1 and the low-speed serial bus pin of each expansion interface 3; the control module 1 detects whether an expansion module is accessed to the expansion interface 3 through a detection signal of the detection pin; the control module 1 reads the module information of the expansion module through a control bus pin.
Further, the bus pins include a high-speed bus pin and a low-speed serial bus pin; the bus gating module 2 comprises a high-speed bus gating unit 20 and a low-speed serial bus gating unit 21; the high-speed bus gating unit 20 is connected between the control module 1 and the high-speed bus pins of each expansion interface 3; and after the control module 1 obtains the bus type information, controlling a corresponding gating unit to gate a corresponding bus for the expansion interface 3 according to the bus type information.
As an example, the number of pins and the pin arrangement of the expansion interface 3 are shown in table 1:
TABLE 1 pin description of expansion interface 3
As an example, the control module 1 reads the module information of the expansion module through the control bus pins IIC _ SCL and IIC _ SDA.
Specifically, the manner that the control module 1 detects whether the expansion interface 3 has an expansion module access through the detection pin may be: the control module 1 judges whether the expansion interface 3 is accessed by an expansion module or not by detecting the high-low level state of the module on-position signal M _ Online of the pin, wherein the module of the control module 1 is pulled up (high level) under the default condition of the module on-position signal M _ Online (the expansion module is not accessed), the expansion module pulls the signal down to low level after the expansion module is accessed, and the control module 1 immediately detects that the signal is changed into low level, namely the expansion module is accessed.
Illustratively, the control module 1 obtains the relevant module information by accessing register values of registers (e.g., EEPROM registers) of the expansion module on the expansion interface 3. For example, table 2 shows the register value definition for the EEPROM register on the module, wherein the control module 1 reads the EEPROM register value on the extension module through the control bus pin (IIC bus pin) and identifies the module type of the extension module from the value of the 0x0000 register; identifying a high speed bus type of the extension module from a value of a 0x0001 register; the low speed serial bus type of the expansion module is identified from the values of the 0x0002 to 0x0006 registers.
TABLE 2 register value definition of registers
Specifically, the control module 1 flexibly configures a high-speed bus of an accessed expansion module as shown in fig. 3, wherein the high-speed gating unit is a high-speed switch unit, and the high-speed bus is configured on demand of the accessed expansion module by the high-speed switch unit. For example, when the expansion interface 3P1 accesses a Wi-Fi module with a PCIe interface, the high-speed switch switches the PCIe bus of the CPU to the expansion interface 3P 1.
In addition, the control module 1 flexibly configures the low-speed serial bus of the accessed expansion module as shown in fig. 4, and gates the accessed expansion module to the required low-speed serial bus by internal bus simulation of the CPLD or the EPLD. For example, the low-speed serial bus of the control module 1 and the CPLD/EPLD is an I2C bus, and the extension interface 3P1 is connected to a bluetooth module with a UART interface, so that the I2C bus of the control module 1 is converted into a UART bus by using a UART bus simulator of the CPLD/EPLD, thereby realizing the module communication of the control module 1 to the extension interface 3 connected to the P1.
By way of example, the electronic product is a wireless communication device, such as a router, a wireless CPE, or the like.
As an example, the type of the extension module may include at least one of: the system comprises a WIFI module, a mobile wireless module, an NAS data storage module, a LAN/WAN wired module, a Bluetooth module, a ZigBee module, a Z-Wave module, a 4G/5G module, a voice module and a sensor module; it should be noted that the type of the extension module is not specifically limited herein, and the extension module may also be of another type.
As an example, if the expansion interface 3 is a slot structure, correspondingly, the interface structure of the expansion module is a plug structure, where the plug interface of the expansion module is adapted to the slot interface of the expansion interface 3.

s10, detecting whether the expansion module is accessed to the expansion interface 3;
s11, if it is detected that an expansion module is accessed on the expansion interface 3, reading module information of the expansion module; the module information is pre-stored in the expansion module;
