[0026] The embodiments of the present application provide a plug-in Flash storage processing system, method, device and storage medium thereof, which are specifically described through the following embodiments.

[0027] In the first aspect, a plug-in Flash storage processing system in an embodiment of the present application is first described.

[0028] Reference Figure 1 As shown, Figure 1 This is an architecture diagram of a plug-in Flash storage processing system provided in some embodiments of the present application. The plug-in Flash storage processing system 100 includes a first conversion module nftl_interface, a driver module nftl_core and a second conversion module nftl_port. The driver module nftl_core is communicatively connected to the first conversion module nftl_interface, and the second conversion module nftl_port is communicatively connected to the first conversion module nftl_interface.

[0029] Among them, the first conversion module nftl_interface is configured to receive file operation instructions sent by the DFS file system, standardize the file operation instructions in the form of interface calls, obtain abstract transaction instructions, and send transaction instructions to the driver module nftl_core. Based on the interface encapsulation of the first conversion module, a unified operation interface is provided for DFS file systems of different platforms, thereby improving the system's adaptability to storage management on different platforms.

[0030] It should be noted that the DFS file system is an underlying system of the operating platform. The DFS file system is used by the operating platform to manage files and generate corresponding file operation instructions according to the operation instructions input by the user.

[0031] Furthermore, the driver module nftl_core is configured to receive a transaction instruction, initialize the transaction instruction into a corresponding instance transaction and execute the instance transaction, and feed back the transaction execution content of the instance transaction to the first conversion module.

[0032] Next, the first conversion module nftl_interface is further configured to receive the transaction execution content, convert the transaction execution content into a bottom-level driving instruction in the form of an interface call, and send the bottom-level driving instruction to the second conversion module nftl_port.

[0033] It should be noted that the second conversion module nftl_port is provided with a modified interface nftl_port_hw.c, and the modified interface nftl_port_hw.c is configured with a modifier __weak, and the modifier __weak is used to weakly associate the modified interface nftl_port_hw.c with the read-write driver file Spinand / mtdcore of the Flash hardware.

[0034] Furthermore, the second conversion module nftl_port is configured to receive the underlying driver instructions, and call the modified interface nftl_port_hw.c according to the underlying driver instructions, so that the Flash hardware can execute the reading and writing driver files Spinand / mtdcore in a relational manner during the process of calling the modified interface nftl_port_hw.c, and then provide a modified interface containing modifiers in the second conversion module. In the process of system porting and use on different platforms, it is only necessary to rewrite the modified interface to complete the adaptation work of storage management for multiple platforms, which solves the problem of complex parameter configuration under different platforms or communication interfaces, and makes the storage use process of Flash more streamlined.

[0035] Further, it should be noted that the first conversion module nftl_interface includes a first interface layer nflt_api.c, a second interface layer nftl_init.c and a third interface layer nftl_hw_interface.c. The first interface layer nflt_api.c is provided with a standardized interface, the second interface layer nftl_init.c is provided with a transaction driver interface, and the third interface layer nftl_hw_interface.c is provided with a bottom-level driver interface. The transaction driver interface is associated with the standardized interface.

[0036] The first interface layer nflt_api.c is configured to receive a file operation instruction and call a standardized interface according to an instruction type of the file operation instruction to perform standardized processing on the file operation instruction.

[0037] Furthermore, the second interface layer nftl_init.c is configured to, in response to the standardized interface being called, call the transaction driver interface according to the association between the transaction driver interface and the standardized interface to encapsulate the standardized file operation instructions into transaction instructions and send the transaction instructions to the driver module.

[0038] Furthermore, the third interface layer nftl_hw_interface.c is configured to receive the transaction execution content fed back by the driver module, and call the underlying driver interface according to the transaction execution content to convert the transaction execution content into underlying driver instructions, thereby reducing the coupling between the driver module and the first conversion module. When a new transaction conversion function needs to be added, it only needs to be expanded at the underlying driver interface level without large-scale modifications to the entire system.

[0039] In general, the plug-in Flash storage processing system adopts a plug-in design and can be compiled independently, making it highly flexible and customizable. Users can then choose and install different plug-ins according to their needs to achieve specific functions.

[0040] In addition, the storage processing system of the plug-in Flash is very lightweight, takes up little space, and does not burden the device. This design not only saves storage space, but also improves the overall efficiency and response speed of the system. Moreover, the storage processing system has the characteristics of multi-platform applicability and can run on various operating systems and devices, providing users with great convenience and seamless experience. Whether on RTOS, operating system programs, or Linux systems, the storage processing system can run stably to meet the needs of different users. In summary, the storage processing system of the present application has the characteristics of high performance, flexibility, lightweight and multi-platform applicability, which will bring users a more convenient and efficient use experience.

[0041] Furthermore, it should be noted that the storage processing system of the plug-in Flash uses C language for instruction editing, and thus can be compiled separately in the form of a black box without the need for secondary compilation through the operating platform, thereby improving the versatility of the storage processing system.

[0042] further, Figure 2 This is a flowchart of the first interface layer calling the standardized interface according to the instruction type of the file operation instruction provided by some embodiments of the present application. The method of calling the standardized interface of the first interface layer may include but is not limited to steps S201 to S204.

[0043] Step S201: receiving a file operation instruction and parsing the instruction type of the file operation instruction.

[0044] Specifically, a file operation instruction is received, and an instruction type of the file operation instruction is parsed.

[0045] Among them, the instruction types of file operation instructions include initialization type, read type and write type, and the interface types of standardized interfaces include a first standardized type, a second standardized type and a third standardized type. The standardized interface of the first standardized type is used to perform standardized encapsulation of file operation instructions of the initialization type, the standardized interface of the second standardized type is used to perform standardized encapsulation of file operation instructions of the read type, and the standardized interface of the third standardized type is used to perform standardized encapsulation of file operation instructions of the write type.

[0046] Step S202: When the instruction type of the file operation instruction is an initialization type, a corresponding calling interface type is a standardized interface of a first standardized type, so as to perform standardized processing on the file operation instruction.

[0047] In a possible implementation, when the instruction type of the file operation instruction is an initialization type, the corresponding calling interface type is a standardized interface nftl_api_init of a first standardized type, so as to perform initialization type standardization processing on the file operation instruction.

[0048] Among them, the standardized interface nftl_api_init belongs to the interface in the first interface layer nflt_api.c.

[0049] Step S203: Alternatively, when the instruction type of the file operation instruction is a read type, the corresponding calling interface type is a standardized interface of a second standardized type, so as to perform standardized processing on the file operation instruction.

[0050] In a possible implementation, when the instruction type of the file operation instruction is an initialization type, the corresponding calling interface type is a standardized interface nftl_api_write of the second standardized type, so as to perform standardized processing on the file operation instruction.

[0053] In a possible implementation, when the instruction type of the file operation instruction is an initialization type, the corresponding calling interface type is a standardized interface nftl_api_read of the third standardized type, so as to perform standardized processing on the file operation instruction.

[0054] Among them, the standardized interface nftl_api_read belongs to the interface in the first interface layer nflt_api.c.

[0055] Reference Figure 3 As shown, Figure 3 It is a flowchart of the second interface layer calling the transaction driven interface according to the association relationship between the transaction driven interface and the standardized interface provided by some embodiments of the present application. The method of the second interface layer calling the transaction driven interface may include but is not limited to steps S301 to S304.

[0056] Step S301: In response to a standardized interface being called, the interface type of the standardized interface is read.

[0057] In a possible implementation, in response to the standardized interface being called, the interface type of the standardized interface is read.

The transaction-driven interface of the first transaction type is associated with a standardized interface of a first standardized type, the transaction-driven interface of the second transaction type is associated with a standardized interface of a second standardized type, and the transaction-driven interface of the third transaction type is associated with a standardized interface of a third standardized type.

[0059] Step S302: When the interface type of the standardized interface is the first standardized type, a transaction driven interface whose interface type is the first transaction type is correspondingly called to encapsulate the standardized file operation instruction into a transaction instruction.

[0060] In a possible implementation, when the interface type of the standardized interface is the first standardized type (ie, the standardized interface is nftl_api_init), the corresponding calling interface type is the transaction driver interface nftl_init of the first transaction type to encapsulate the standardized file operation instructions into transaction instructions.

[0061] The transaction driver interface nftl_init belongs to the interface in the second interface layer nftl_init.c.

[0062] Step S303: Alternatively, when the interface type of the standardized interface is the second standardized type, a transaction driver interface whose interface type is the second transaction type is correspondingly called to encapsulate the standardized file operation instruction into a transaction instruction.

[0063] In a possible implementation, when the interface type of the standardized interface is the second standardized type (ie, the standardized interface is nftl_api_write), the corresponding calling interface type is the transaction driver interface _nand_write of the second transaction type to encapsulate the standardized file operation instructions into transaction instructions.

[0064] Among them, the transaction driver interface _nand_write belongs to the interface in the second interface layer nftl_init.c.

[0065] Step S304: Alternatively, when the interface type of the standardized interface is the third standardized type, a transaction driver interface whose interface type is the third transaction type is correspondingly called to encapsulate the standardized file operation instruction into a transaction instruction.

[0066] In a possible implementation, when the interface type of the standardized interface is the third standardized type (ie, the standardized interface is nftl_api_read), the corresponding calling interface type is the transaction driver interface _nand_read of the third transaction type to encapsulate the standardized file operation instructions into transaction instructions.

The method of the third interface layer calling the underlying driver interface according to the transaction execution content may include but is not limited to steps S401 to S402.

[0069] Step S401: parse the transaction execution content.

[0070] Step S402: When the transaction execution content belongs to the content of the read operation, the underlying driver interface whose interface type is the first transaction type is correspondingly called to convert the transaction execution content into an underlying driver instruction of the read type.

[0071] In a possible implementation, when the transaction execution content belongs to the content of a read operation, that is, the instance transaction executes the transaction content belonging to a write operation during the running process, the corresponding calling interface type is the underlying driver interface nftl_nand_read_page of the first transaction type to convert the transaction execution content into an underlying driver instruction belonging to the read type.

[0072] Step S403: Alternatively, when the transaction execution content belongs to the content of a write operation, the underlying driver interface of the corresponding calling interface type is the second transaction type, so as to convert the transaction execution content into an underlying driver instruction of the write type.

[0073] In a possible implementation, when the transaction execution content belongs to the content of a write operation, that is, the instance transaction executes the transaction content belonging to a write operation during the running process, the corresponding calling interface type is the underlying driver interface nftl_nand_write_page of the second transaction type to convert the transaction execution content into an underlying driver instruction belonging to a read type.

[0074] Further, the interface type of the modified interface includes a first modification type and a second modification type, Figure 5 It is a flowchart of the second conversion module calling the modified interface according to the underlying driving instruction provided by some embodiments of the present application. The method of the second conversion module underlying driving instruction calling the modified interface may include but is not limited to steps S501 to S502. Step S501: parsing the underlying driver instructions.

[0075] Step S501: When the bottom-level driving instruction is of a read type, the corresponding calling interface type is a modified interface of a first modified type.

[0076] In a possible implementation, when the bottom-level driver instruction is of a read type, the corresponding calling interface type is a modified interface (__weak)_nftl_port_hw_read_page of a first modified type.

[0077] Step S502: Alternatively, when the bottom-level driving instruction is of a write type, the corresponding calling interface type is a modified interface of a second modified type.

[0078] In a possible implementation, when the bottom-level driver instruction is of a write type, the corresponding calling interface type is a modified interface (__weak)_nftl_port_hw_write_page of the second modified type.

[0079] Further, in some embodiments, Figure 6 This is a flowchart of a driver module provided by some embodiments of the present application that initializes a transaction instruction into a corresponding instance transaction and executes the instance transaction. The method for the driver module to initialize a transaction instruction into a corresponding instance transaction and execute the instance transaction may include but is not limited to steps S601 to S603.

[0080] Step S601: receiving a transaction instruction and parsing the instruction type of the transaction instruction.

[0081] In a possible implementation, a transaction instruction is received and an instruction type of the transaction instruction is parsed, wherein the instruction type of the transaction instruction includes an initialization type, a read type, and a write type.

[0082] Step S602: when the instruction type of the transaction instruction is an initialization type, the transaction instruction is initialized as an instance transaction belonging to the first function type and the instance transaction is executed.

[0083] In a possible implementation, when the instruction type of the transaction instruction is an initialization type, the transaction instruction is initialized as an instance transaction belonging to the first function type and the instance transaction is executed.

[0084] Among them, the corresponding transaction execution content in the instance transaction belonging to the first function type includes an initialization parameter transaction and a power-off data recovery transaction.

[0085] Step S603: Alternatively, when the instruction type of the transaction instruction is a read type or a write type, the transaction instruction is initialized as an instance transaction belonging to the second functional type and the instance transaction is executed.

[0086] In a possible implementation, when the instruction type of the transaction instruction is a read type or a write type, the transaction instruction is initialized as an instance transaction belonging to the second function type and the instance transaction is executed.

[0087] The transaction execution contents correspondingly executed in the instance transaction belonging to the second functional type include write-balancing transactions, bad block management and recovery transactions, and logical address to physical address mapping transactions.

[0088] Furthermore, the present application embodiment also proposes a plug-in Flash storage processing method, which is applied to the plug-in Flash storage processing system 1000, referring to Figure 7 , Figure 7 This is a flowchart of a storage processing method of a plug-in Flash provided in some embodiments of the present application. The storage processing method may include but is not limited to steps S701 to S704.

[0089] Step S701: The first conversion module responds to the file operation instruction sent by the DFS file system, standardizes and encapsulates the file operation instruction in the form of interface call, obtains an abstract transaction instruction, and sends the transaction instruction to the driver module.

[0090] Step S702: the driving module receives the transaction instruction, initializes the transaction instruction into a corresponding instance transaction, executes the instance transaction, and feeds back the transaction execution content of the instance transaction to the first conversion module.

[0091] Step S703: the first conversion module receives the transaction execution content, converts the transaction execution content into a bottom-level driving instruction in the form of an interface call, and sends the bottom-level driving instruction to the second conversion module.

[0092] Step S704: the second conversion module receives the bottom-layer driver instruction, and calls the modified interface according to the bottom-layer driver instruction, so that the Flash hardware can execute the reading and writing of the driver file in a correlation manner during the process of calling the modified interface.

[0093] The storage processing method of the plug-in Flash and the storage processing system of the plug-in Flash are based on the same inventive concept. The first conversion module responds to the file operation instruction sent by the DFS file system, standardizes the file operation instruction in the form of interface call, obtains the abstract transaction instruction, and sends the transaction instruction to the driver module; then, the driver module receives the transaction instruction, initializes the transaction instruction to the corresponding instance transaction and executes the instance transaction, and feeds back the transaction execution content of the instance transaction to the first conversion module; then, the first conversion module receives the transaction execution content, converts the transaction execution content into the underlying driver instruction in the form of interface call, and feeds back the transaction execution content to the second conversion module. The module sends the underlying driver instruction; finally, the second conversion module receives the underlying driver instruction, and calls the modified interface according to the underlying driver instruction, so that the Flash hardware can execute the reading and writing of the driver file in a correlation manner during the process of calling the modified interface, and then based on the interface encapsulation of the first conversion module, a unified operation interface is provided for the DFS file systems of different platforms, which improves the adaptability of the system to storage management on different platforms. At the same time, in the process of transplantation and use on different platforms, it is only necessary to rewrite the modified interface to complete the adaptation work of storage management on multiple platforms, which solves the problem of complex parameter configuration under different platforms or communication interfaces, making the storage use process of Flash more streamlined.
