Description

Technical Field

[0001] The present disclosure relates to the field of computer storage technologies, and in particular, to a processing method, apparatus, electronic device, and storage medium for storage units. Background Art

[0002] UFS (Universal Flash Storage) chips adopt BGA (Ball Grid Array) packaging technology and are directly soldered onto the motherboard. This method not only increases the difficulty in the R & D and testing stages, is not conducive to the introduction of asynchronous verification, but also raises the after-sales maintenance cost.

[0040] To make the objectives, features, and advantages of the present disclosure more obvious 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. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0041] According to the first aspect of the embodiments of the present disclosure, a processing method for a storage unit is provided, as Figure 1 shown, the method includes the following steps:

[0042] Step 101, determine the type of the storage unit inserted into the electronic device through the first detection method or the second detection method, where the first detection method is a hardware detection method and the second detection method is a software detection method.

[0043] The electronic device can be any device that can receive and process data and support the insertion of a storage unit. For example, a laptop computer, an in-vehicle intelligent system, etc. When a storage unit is inserted into the electronic device, its type is first determined through a hardware detection method or a software detection method. Specifically, the hardware detection method analyzes the physical characteristics or electrical characteristics of the storage unit through the hardware circuit of the electronic device to determine its type. The software detection method is to identify the type of the storage unit by running a pre-set software program. These software programs can analyze and determine the type of the storage unit by reading the metadata of the storage unit or sending specific commands to the storage unit to obtain its response. The types of storage units can include SSD, UFS, etc.

[0044] Step 102, determine the data transmission protocol corresponding to the type of the storage unit.

[0045] Each type of storage unit corresponds to a specific data transmission protocol to meet its data transmission requirements. For example, SSD usually uses the PCIe protocol for data transmission, and UFS uses the UFS protocol. Therefore, once the type of the storage unit is determined, the corresponding data transmission protocol is immediately determined.

[0046] Step 103, control the conduction of the transmission line corresponding to the data transmission protocol through a switching element, so that the storage unit performs data interaction with the electronic device through the transmission line.

[0047] Inside the electronic device, data is transmitted between the storage unit and other components of the electronic device through a specific transmission line. The transmission line is designed according to the data transmission protocol adopted. The switching element can be an electronic device with switching characteristics such as a transistor or a multiplexer. When the system detects the type of the storage unit and determines the corresponding data transmission protocol, a control signal is sent to the switching element. The control signal changes the state of the switching element, making it conduct or cut off the transmission line corresponding to the determined data transmission protocol.

[0048] The processing method for the storage unit in this embodiment automatically identifies the type of the storage unit inserted into the electronic device. Then, it determines the transmission protocol corresponding to this type and controls the conduction of the transmission line corresponding to this transmission protocol, enabling the storage unit to perform data interaction with the electronic device through this transmission line. Different types of storage units can be shared through one socket without affecting the performance of the storage unit.

[0049] In an embodiment of the present disclosure, the type of the storage unit inserted into the electronic device is determined through a first detection method, which can be specifically implemented by the following technical means: based on the pin information of the storage unit inserted into the electronic device or the internal device identification register, determine the type of the storage unit.

[0050] The storage unit usually has a specific pin layout or identification. For example, there are differences in the arrangement and quantity of power pins and data pins. Based on these differences, a detection circuit is designed to detect the connection of the pins of the storage unit, thereby determining its type. For example, an SSD usually has more pins for high-speed data transmission, such as pins related to the PCIE interface. By detecting whether these specific pins are connected, the type of the storage unit can be determined.

[0051] In addition to the pin identification method, the type of the storage unit can also be determined by using the device identification register inside the storage unit. The storage unit usually has a device identification register inside, which is used to store information such as the manufacturer name, device model, and storage capacity. The motherboard of the electronic device can communicate with the storage unit through a specific bus (such as the SPI bus or I2C bus, etc.) and read the information in the device identification register. According to this information, the type of the storage unit can be determined. For example, if the information in the device identification register represents the specific model code of a certain SSD manufacturer, it can be determined that the storage unit is of the SSD type. If the information in the device identification register conforms to the coding rule of the UFS device, it is determined that the storage unit is of the UFS type.

[0052] In this embodiment, by identifying the pin layout and connection of the storage unit, as well as reading the device identification register information inside the storage unit, the type of the storage unit is accurately and efficiently determined.

[0053] In one embodiment of the present disclosure, the type of the storage unit inserted into the electronic device is determined by a second detection method, including: sending a device identification command to the storage unit inserted into the electronic device; obtaining the response information of the storage unit to the device identification command; and determining the type of the storage unit according to the response information.

[0054] Specifically, a dedicated storage unit detection program can be embedded in the BIOS. The detection program sends a device identification command to the storage unit and determines its type according to the response of the storage unit. For example, the BIOS sends a general device identification command, and different types of storage units such as SSDs and UFSs will return different response information according to their respective communication protocols. The BIOS determines the type of the storage unit by analyzing this response information.

[0055] In another embodiment, after the operating system is started, the operating system's device driver can interact with the storage unit and obtain detailed information about the storage unit. Taking the Linux system as an example, the storage driver module in the kernel can query relevant attributes of the storage unit, such as obtaining type information by accessing a specific file system or device interface of the storage unit. If the operating system finds specific identifiers or attributes related to an SSD in the file system, it determines that the storage unit is of the SSD type. Similarly, if identifiers related to UFS are found, it can be determined that the storage unit is of the UFS type.

[0056] In one embodiment of the present disclosure, a data transfer protocol corresponding to the type of the storage unit can be determined based on a preset relationship look-up table.

[0057] Specifically, in the control chip (such as the south bridge chip or a dedicated storage controller chip) of the electronic device motherboard, a preset relationship look-up table is established in advance. The preset relationship look-up table is a data structure used to associate storage unit types with their corresponding data transfer protocols. After the type of the storage unit is detected, the appropriate data transfer protocol can be quickly determined by looking up the preset relationship look-up table.

[0058] For example, a preset relationship look-up table is established, which records the following information: "SSD - PCIe, HDD - SATA, UFS - UFS". When the system detects that the storage unit is an SSD, the corresponding PCIe protocol is found through this table.

[0059] In the BIOS or the driver of the operating system, establish a query function for looking up a preset relationship comparison table. When the system detects the type of the storage unit, call this query function to look up the corresponding protocol.

[0060] For example, in the storage initialization code of the BIOS, when the system detects that the storage unit is an SSD, it will call a function to query the preset relationship comparison table. This function will return the PCIe protocol corresponding to the SSD.

[0061] The method of this embodiment is simple and efficient. By using a lookup table instead of a cumbersome algorithm, the running speed of the program is improved, and the complexity of the code is simplified.

[0062] In an embodiment of the present disclosure, a data transmission protocol corresponding to the type of the storage unit can be determined by a hardware logic module. The hardware logic module can be a logic circuit composed of logic gates or a programmable logic device, which will be described separately below:

[0063] The hardware logic circuit is composed of logic gates (such as AND gates, OR gates, NOT gates, etc.). It can output a corresponding data transmission protocol signal through logical operations according to the input signal of the storage unit type.

[0064] For example, assume a hardware logic circuit with two inputs. One represents the type of the storage unit (high level represents SSD, low level represents UFS), and the other is an enable signal (used to control the opening and closing of the circuit). When the input of the storage unit type is high level, after a series of logical operations by the logic gates, the circuit outputs a signal representing the PCIe protocol. When the input of the storage unit type is low level, the circuit will output a signal representing the UFS protocol.

[0065] A programmable logic device (such as an FPGA) is a chip whose logic function can be changed. By writing code, the programmable logic device can determine the data transmission protocol according to the type of the storage unit.

[0066] For example, in an FPGA (Field Programmable Gate Array), write a program to implement the function of a lookup table or logical judgment. When the signal of the storage unit type is input to the FPGA, the FPGA will perform logical operations according to the internally written program and output the corresponding protocol signal. For example, if the input signal represents that the storage unit is an SSD, the FPGA will output a signal representing the PCIe protocol; if the input signal represents that the storage unit is a UFS, the FPGA will output a signal representing the UFS protocol. This embodiment uses hardware logic execution, which has a higher processing speed and parallel processing ability.

[0067] In one embodiment of the present disclosure, the transmission line corresponding to the data transmission protocol is controlled to be turned on by a switching element, so that the storage unit can perform data interaction with the electronic device through the transmission line. Specifically, it can be achieved by software, such as the driver of the BIOS or the operating system, sending a control instruction to control the state of the corresponding transistor or the selection of the multiplexer:

[0068] If the switching element is a transistor (such as a MOSFET transistor), the on - off state between the source and the drain can be changed by controlling its gate voltage, thereby controlling the on - off of a specific data transmission line.

[0069] For example, when the storage unit is an SSD and it is recognized and the PCIe protocol is determined to be used, a high - level voltage is applied to the gate of the MOSFET transistor connected to the PCIe line. This changes the transistor from the cut - off state to the on - state, thus allowing data to be transmitted between the SSD and other components through the PCIe line.

[0070] If the switching element is a multiplexer, the multiplexer can select one of multiple input signals for output. It has multiple input ports inside, each port is connected to a line corresponding to a different protocol, and the output port is connected to other components. By selecting an appropriate input port, the multiplexer can transmit data from the selected storage unit to other components.

[0071] Assume that when an SSD is recognized, the multiplexer conducts the input port connected to the PCIe line inside with the output port. In this way, the SSD can transmit data to other components through the PCIe line.

[0072] Figure 2 Fig. shows a schematic diagram of an application scenario of an embodiment of the present disclosure, such as Figure 2 shown. First, determine the type of the inserted storage unit. If it is UFS, the transmission line corresponding to the UFS protocol is turned on through the switching element, thereby realizing interaction with the CPU. If it is an SSD, the transmission line corresponding to the PCIE protocol is turned on, thereby realizing interaction with the CPU.

[0073] According to the second aspect of the embodiments of the present disclosure, there is provided a processing device for a storage unit, as Figure 3 shown. The device includes:

[0074] A detection module 301, configured to determine the type of the storage unit inserted into the electronic device by a first detection method or a second detection method, where the first detection method is a hardware detection method and the second detection method is a software detection method;

[0076] The line conduction module 303 is configured to control the conduction of the transmission line corresponding to the data transmission protocol through a switching element, so that the storage unit performs data interaction with the electronic device through the transmission line.

[0077] In an embodiment of the present disclosure, the detection module 301 is further configured to determine the type of the storage unit based on the pin information of the storage unit inserted into the electronic device or the device identification register inside.

[0078] In an embodiment of the present disclosure, the detection module 301 is further configured to send a device identification command to the storage unit inserted into the electronic device; obtain the response information of the storage unit to the device identification command; and determine the type of the storage unit according to the response information.
