Description

Technical Field

[0001] The present invention relates to the technical field of computer storage, and particularly to a data storage processing method, a data storage processing circuit, and an electronic device. Background Art

[0002] The non-volatile data on the motherboard of an electronic device includes the following four parts: 1. Data for describing the motherboard FRU (Field Replace Unit); 2. Data saved by the motherboard management module in the EMMC (Embedded MultiMedia Card); 3. Data saved by the BIOS (Basic Input Output System) in the non-volatile ROM of the PCH (computer motherboard BGA) RTC (Real Time Clock); 4. Data that needs to be restored when the motherboard FPGA is powered on and saved in the management module FLASH.

[0003] Currently, the above four parts of data are stored separately in different chips, with decentralized storage and separate maintenance. Among them, the first part of the data uses an independent Flash chip, which occupies the layout space of the motherboard. And when the Flash chip fails and needs to be replaced, it is easy to bring problems such as complex code development and maintenance due to the instruction differences of Flash chips from different manufacturers and models. Specifically, the position of the independent Flash chip on the motherboard can be referred to Figure 1 the U72 position shown, which occupies the motherboard layout space. And when reading and writing FRU data, the independent Flash chip needs to be connected to an I2C bus and read and written using a preset slave address, occupying the I2C resource. In the case of a failure of the motherboard management module, even the second part of the data cannot be directly read. The third part of the data requires independent battery power supply. When the battery power is insufficient, data loss will occur. In short, the current data management form of decentralized storage and separate maintenance of the non-volatile storage data on the motherboard occupies resources and is difficult to maintain data.

[0023] The principles and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and then implement the present invention, and do not limit the scope of the present invention in any way. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to be able to convey the scope of the present invention to those skilled in the art completely.

[0024] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Figure 2 Shows a schematic layout diagram of the EMMC on the motherboard in an embodiment of the first embodiment of the present invention.

[0026] Reference Figure 2As shown, the EMMC chip can be laid out at the U64 position of the motherboard layout. The EMMC chip consists of an embedded storage solution with an MMC (Multimedia Card) interface, a flash memory device, and a main controller. And all interfaces and controllers are encapsulated in a small BGA structure. Its interface speed is up to 52 MBytes per second. EMMC has fast and upgradeable performance. Based on the NAND flash memory chip, it additionally integrates a controller and encapsulates the two into a BGA-structured chip, thus greatly reducing the space occupied on the PCB motherboard. Therefore, the EMMC chip has a powerful data storage capacity and fast data processing capabilities, and the space it occupies on the motherboard layout is very small. In addition, EMMC integrates a Flash Controller (Flash chip controller) inside to complete functions such as wear-leveling, bad block management, and ECC (Error Correcting Code) verification. At the same time, eMMC can have very good read and write performance by using technologies such as Cache and Memory Array.

[0027] Therefore, in the data storage and processing method of the embodiment of the present invention, the non-volatile data that needs to be read during the startup processes of multiple systems of the motherboard of the electronic device is stored in the EMMC of the motherboard, and a suitable data management strategy is adopted to manage the non-volatile data stored thereon.

[0028] Figure 3 The implementation process schematic diagram of the data storage and processing method of the embodiment of the present invention is shown.

[0029] Reference Figure 3 , the data storage and processing method of the embodiment of the present invention at least includes the following operation processes: Operation 301, storing the non-volatile data that needs to be read during the startup processes of multiple systems of the motherboard of the electronic device in the EMMC of the motherboard; Operation 302, determining the management strategy for managing the data in the motherboard EMMC according to the working states of the BIOS and management module of the electronic device, and performing data management according to the strategy.

[0030] In Operation 301, the non-volatile data that needs to be read during the startup processes of multiple systems of the motherboard of the electronic device is stored in the EMMC of the motherboard.

[0031] In this embodiment of the present invention, the non-volatile data that needs to be read during the startup processes of multiple systems may include at least one of the following data: First data, data for describing the field replaceable units of the motherboard; Second data, system data of the BIOS; Third data, data that needs to be restored when the motherboard FPGA is powered on; Fourth data, data saved in the EMMC by the motherboard management module.

[0032] Specifically, after saving the data used to describe the motherboard FRU (Field Replace Unit) to the EMMC, firstly, an independent Flash can be no longer used to save this data, effectively saving the motherboard layout space. Secondly, there is no need to connect to a preset I2C bus to read and write this data, effectively improving the processing efficiency of the management module for the data describing the motherboard FRU (Field Replace Unit). Moreover, the selection of an independent Flash chip is avoided, as well as the instruction differences and the resulting complex and cumbersome code development and maintenance operations when accessing Flash chips of different manufacturers and models. Thus, when the Flash chip is damaged, the problem of the entire motherboard needing to be replaced is further avoided.

[0033] The system data of the BIOS can include the data saved in the non-volatile ROM on the PCH RTC (Platform Controller Hub Real_TimeClock, real-time clock on the south bridge chip). After saving the system data of the BIOS in the EMMC chip, the problem of data loss in the non-volatile ROM caused by power failure of the PCH RTC after the independent power supply battery in the traditional PCH RTC solution fails to supply power normally can be effectively avoided. Thus, when the BIOS POST is abnormal due to the data saved in the non-volatile ROM of the PCH RTC, the problem of being unable to obtain data for specific analysis and having to clear the data can be effectively avoided.

[0034] For the data that needs to be restored when the FPGA on the management module FLASH is powered on, storing it in the EMMC can ensure that these data can be normally restored during the FPGA power-on process regardless of whether the management module can work properly, thus ensuring the normal startup of the motherboard system.

[0035] For the data saved by the motherboard management module in the EMMC (Embedded Multi Media Card, embedded memory), it can ensure the smooth startup of the BIOS.

[0036] In this embodiment of the present invention, for the first data used to describe the motherboard field replaceable unit, the following operations can be adopted to store multiple non-volatile data of the motherboard of the electronic device in the EMMC of the motherboard: partition the EMMC to obtain multiple storage areas, format the storage areas into a specified file system, further save the first data to the first specified storage area among the multiple storage areas, and perform file management on the first data based on the file system of the specified file area.

[0037] Specifically, inside the EMMC, the NAND Flash chip (Flash memory array) and the Device Controller chip (also called Flash controller, EMMC controller) are encapsulated together. The Flash controller is responsible for managing the memory and provides a standard interface, enabling the EMMC to automatically adjust the working modes of the host and the slave without bit limit and eliminating the need to handle other complex NAND Flash compatibility and management issues. Meanwhile, the controller serves as the connection medium between the applications of its card and the multimedia bus, and it can complete protocol conversion before the application program bus and the standard multimedia bus.

[0038] NAND Flash is a non-volatile memory, usually used in embedded systems to store systems, applications, data, etc., similar to the hard disk in a PC system. Inside the EMMC, the NAND Flash is divided into several main areas. For example, the EMMC can be divided into areas such as Boot Area Partitions, RPMB (Replay Protected Memory Block) Partition, General Purpose partition, and User Data Area.

[0039] Among them, Boot Area Partitions can further include Boot Area Partition 1 and Boot Area Partition 2. This partition is mainly designed to support booting the system from the EMMC. The data in this partition can be read out through a very simple protocol after the EMMC is powered on.

[0040] The RPMB Partition uses HMAC SHA-256 and Write Counter to ensure that the data stored inside the RPMB is not illegally tampered with. In practical applications, the RPMB Partition is usually used to store security-related data, such as fingerprint data, keys related to secure payment, etc.

[0041] General Purpose Partition can also include multiple sub-areas such as General Purpose Partition 1 to 4. The General Purpose Partition is mainly used to store system or user data. Usually, the General Purpose Partition does not exist when the EMMC chip leaves the factory and needs to be actively configured before it exists.

[0042] For example, the first data used to describe the motherboard field replaceable unit can be stored in this partition. The NAND Flash chip memory array of the EMMC chip can configure a file system, which specifies the rules for naming files, such as the maximum number of characters in the file name, which characters can be used, and how long the file name suffix can be in some systems. The file system also includes the format of the specified path for finding files through the directory structure. The file system can be one of various file systems such as FAT, NTFS, CDFS, RAW, JFFS2, or YAFFS2. As for which specific file system to adopt, no specific limitation is made here.

[0043] The User Data Area is mainly used to store system and user data. The User Data Area is usually repartitioned. For example, in the Android system, sub-areas such as boot, system, and user data are usually separated in this area.

[0044] In this way, by storing the motherboard FRU information in the EMMC, the Flash chip that independently stores the motherboard FRU information can be removed from the motherboard, effectively releasing the motherboard Layout space and the i2c resources occupied by the Flash chip.

[0045] In this embodiment of the present invention, for the second data of the BIOS system data and the third data that needs to be restored when the motherboard FPGA is powered on, the following operations can be used to store multiple non-volatile data of the motherboard of the electronic device in the EMMC of the motherboard: save the second data to the second specified storage area in the multiple storage areas, and manage the second data based on the data offset of the second data in the second specified storage area, and save the third data to the third specified storage area in the multiple storage areas, and manage the third data based on the data offset of the third data in the third specified storage area.

[0046] For example, the second data and the third data can be stored in the User Data Area of the EMMC chip. The NAND Flash in the EMMC is configured with multiple areas. For each partition, the position where the file is stored in the EMMC is managed by the data offset.

[0047] In operation 302, according to the working states of the BIOS and the management module of the electronic device, determine the management policy for managing the data in the motherboard EMMC, and perform data management according to the policy.

[0048] In this embodiment of the present invention, according to the working states of the BIOS and the management module of the electronic device, a management strategy for the data in the management mainboard EMMC is determined, and data management is performed according to the strategy, including: when the management module is working normally, reading and writing multiple non-volatile data in the EMMC through the management module.

[0049] Specifically, when the management module is working normally, the management module itself manages the data included in the data that needs to be restored when the mainboard FPGA is powered on, and saves the relevant information to the EMMC. The management module will also actively read the data that needs to be restored when the mainboard FPGA is powered on from the EMMC and transfer it to the FPGA for data restoration when powered on or after the FPGA is updated. In addition, the BIOS can read and modify the information included in the system data of the BIOS through in-band commands.

[0050] In this embodiment of the present invention, according to the working states of the BIOS and the management module of the electronic device, a management strategy for the data in the management mainboard EMMC is determined, and data management is performed according to the strategy, including: when the management module fails and the BIOS works normally, the BIOS reads and writes multiple non-volatile data in the EMMC through the controller of the mainboard.

[0051] Specifically, when the management module is abnormal and cannot work normally, and the BIOS can work normally, the BIOS can read and modify the information included in the system data of the BIOS by communicating with the FPGA. In addition, the data at a specified position in the EMMC can be read out by communicating with the FPGA through the shell tool integrated in the BIOS. At this time, the FPGA itself can read data from the EMMC to complete data restoration.

[0052] In this embodiment of the present invention, according to the working states of the BIOS and the management module of the electronic device, a management strategy for the data in the management mainboard EMMC is determined, and data management is performed according to the strategy, including: when the working states of the management module show that both the management module and the BIOS have failed, reading and writing multiple non-volatile data in the EMMC through an external general-purpose reading and writing device connected to the EMMC.

[0053] Specifically, the reserved pins of the EMMC chip can be used to enable the EMMC to perform data reading and writing operations through an external reader and writer. When both the management module and the BIOS cannot work normally, an external general-purpose reader and writer can be used to read and write the data in the EMMC through the reserved pins of the EMMC chip.

[0054] For example, the pins VCC, VCCQ, GND (or VSS), CLK, CMD, and D0 of the EMMC chip can be connected to independent jumpers on the motherboard so that the data in the EMMC can be read or written to the EMMC with the help of an external general-purpose reader / writer. At the same time, these pins are also connected to the FPGA. The FPGA reads and modifies the data in the EMMC through these pins by implementing the EMMC read / write protocol.

[0055] In the data storage and processing method according to the embodiment of the present invention, non-volatile data that needs to be read during multiple system startup processes of the motherboard of an electronic device is stored in the EMMC of the motherboard; according to the working states of the BIOS and the management module of the electronic device, a management strategy for managing the data in the motherboard EMMC is determined, and data management is performed according to the strategy. In this way, various types of dispersed motherboard data are saved in the EMMC and managed through a specific management strategy. For example, it can be saved in a specific data format, and the FPGA can be used as a converter to accelerate the reading of the data in the EMMC. Thereby, the complexity of motherboard data maintenance is effectively reduced, the over-reliance of the electronic device system startup and operation on the management module is avoided, and the resilience of the electronic device system is effectively improved.

[0056] Similarly, based on the above data storage and processing method, the embodiment of the present invention further provides a computer-readable storage medium. The computer-readable storage medium stores a program, and when the program is executed by a processor, the processor is caused to perform at least the following operation steps: Operation 301, storing non-volatile data that needs to be read during multiple system startup processes of the motherboard of the electronic device in the EMMC of the motherboard; Operation 302, determining a management strategy for managing the data in the motherboard EMMC according to the working states of the BIOS and the management module of the electronic device, and performing data management according to the strategy.

The EMMC is used to store multiple non-volatile data of the motherboard, and the electronic device can determine a management strategy for managing the data in the motherboard EMMC according to the working states of the BIOS and the management module of the electronic device, and perform data management according to the strategy.

[0058] In this embodiment of the present invention, the data storage and processing circuit further includes: a general-purpose reader / writer, which is connected to the EMMC through the controller and is used to read and write multiple non-volatile data in the EMMC when the working state of the management module shows that both the management module and the BIOS have failed.
