Example one
Referring to fig. 1, the present invention provides a method for repairing firmware of a memory, which specifically includes the following steps:
step S100: data extraction is carried out on a memory to be overhauled, and equipment data information of the memory to be overhauled is obtained;
further, step S100 includes:
step S110: traversing the memory to be overhauled to obtain a system storage data set of the memory to be overhauled;

In particular, memories are memory devices used in modern information technology for storing information. The concept is wide, and has a plurality of layers, and in a digital system, the memory can be used as long as binary data can be stored; in an integrated circuit, a circuit without a physical form and with a storage function is also called a memory, such as a RAM, a FIFO and the like; in the system, the storage device in physical form is also called a memory, such as a memory bank, a TF card and the like. All information in the computer, including the input raw data, the computer program, intermediate run results, and final run results, is stored in memory.
The firmware refers to a device "driver" stored in the device, and through the firmware, the operating system can implement the operation of a specific machine according to the standard device driver. In general, FLASH memory-based solid state disks employ FLASH chips as storage media, which are also known as SSDs. Its appearance can be made in a variety of patterns, for example: notebook hard disks, micro hard disks, memory cards, U disks and the like. The SSD solid state disk has the greatest advantages of being movable, being free of power control for data protection, being suitable for various environments and being suitable for individual users.
However, in the prior art, in the process of circulating and calling data by using a storage medium of a solid state disk, the data of a key sector covered by a chip channel cannot be quickly overhauled, so that the calling response rate of the data is greatly reduced.
In order to solve the problems, the application provides a memory firmware maintenance method, which can obtain related data of a storage medium by extracting current data of a target memory, on the basis of which, the data of a key sector is screened and marked, so as to obtain higher maintenance parameters, and further scan a service area covered by a current chip channel of the target memory by the maintenance parameters, further filter a specific program of the storage medium on the scanned data, decode and extract program running data obtained by filtering, and compare and detect the extracted standard sector data and actual sector data, so as to determine the defect position of the actual sector data, further timely maintain, achieve the technical effects of quickly maintaining the key sector data covered by the chip channel and greatly improving the retrieval response rate of the data.
Specifically, the memory to be overhauled is a storage device with functions of data storage, calling and the like, and includes devices such as a notebook hard disk, a micro hard disk, a memory card and a U disk, and the device data information is data circulation information of the device during normal operation, and includes a channel size, a data response rate and the like. When data extraction is performed on a memory to be overhauled, specifically, the memory to be overhauled can be traversed to obtain a system storage data set of the memory to be overhauled, wherein the system storage data set is information of a solid state disk system and a chip of the memory. Meanwhile, the target application scenario is a computing device that the storage device can be used for, exemplarily, if the storage device is a hard disk of a notebook computer, most of the stored data are internal system operation driving data, external application operation data and the like, and then a data traversal screening model can be set up based on the target application scenario, generally, the application devices of the storage device are different, so that the emphasis points of data circulation are different, the data traversal screening model can perform differential screening on circulation data of different application scenarios, so that sectors covered by chip channels corresponding to the target device are accurately locked and effectively screened, and the device data information can be obtained by inputting the system storage data set into the data traversal screening model for training.
Step S200: determining a first overhaul parameter, a second overhaul parameter and a third overhaul parameter according to the equipment data information;
step S300: marking the first overhaul parameter, the second overhaul parameter and the third overhaul parameter by parameter labels respectively, and performing advanced optimization of data on the marked parameters to generate advanced overhaul parameters;
specifically, after the equipment data information is obtained, the equipment data information needs to be screened for key feature overhaul data, wherein the first overhaul parameter, the second overhaul parameter and the third overhaul parameter are the screened key feature overhaul data, the first overhaul parameter can be understood as the number of chips, the second overhaul parameter can be understood as the number of channels, and the third overhaul parameter can be understood as the page size, and then parameter label marking is respectively performed on the first overhaul parameter, the second overhaul parameter and the third overhaul parameter, that is, the first overhaul parameter is marked as a label representing the number of chips, the second overhaul parameter is marked as a label representing the number of channels, the third overhaul parameter is marked as a label representing the page size, and then advanced optimization of data is performed on the three label, so that the three label labels are fused into one advanced overhaul parameter, and the advanced overhaul parameter can be realized in a feature fusion manner, and the advanced overhaul parameter covers the three label.
Step S400: scanning a service area of a chip channel of the memory to be overhauled through the high-level overhaul parameters to obtain a scanning data set;
step S500: performing firmware data filtering on the scanning data set to obtain target firmware data;
specifically, after the advanced overhaul parameters are obtained, service area scanning may be performed on a chip channel of the memory to be overhauled based on the advanced overhaul parameters, that is, a service area of data circulation of the memory chip is scanned, and a scanned data set may be obtained, where the scanned data set is a data set covered by the number of chips, a data covered by the number of channels, and a data set covered by the page size.
Furthermore, the scanning data set can be filtered to obtain target firmware data, that is, important firmware information is filtered for data covered by the number of chips, data covered by the number of channels, and data covered by the size of pages, and generally, software solidified on hardware is damaged, including bad blocks, read errors, module loss, logic bad tracks, verification errors and the like, and the corresponding repairing method includes methods of firmware repairing, chip data recombination, interface conversion, physical replacement and the like. Different technical solutions are used for different situations. Therefore, the target firmware data is damaged software data, including bad block data, read error data, module lost data, logic bad track data, check error data, and the like.
Step S600: and performing decoding data extraction on the target firmware data to obtain extracted decoding data, and performing mirror image extraction on logic data of the target firmware data based on the extracted decoding data.
Further, as shown in fig. 2, step S600 includes:
step S610: calling a first initialization instruction of the memory to be overhauled, and initializing the memory to be overhauled;
step S620: transmitting the sector data address of the target firmware data to the memory to be overhauled, and decoding the sector data address based on an embedded decoding table to obtain the extracted decoded data;
step S630: acquiring preset byte information of the sector data address;
step S640: obtaining conversion byte information of the extracted decoding data;
step S650: judging whether the conversion byte information and the preset byte information are consistent or not;
step S660: and if the converted byte information is consistent with the preset byte information, generating a first extraction instruction, and performing mirror image extraction on the logic data of the target firmware data.
Specifically, after the target firmware data is obtained, decoding data extraction needs to be performed on the target firmware data, specifically, a first initialization instruction of the memory to be overhauled may be called first, the memory to be overhauled is initialized, that is, circulation data of the storage device is initialized, and after the initialization is successful, a sector data address of the target firmware data may be transmitted to the memory to be overhauled, that is, a sector data address covered by damaged software data is uploaded to the storage device, data decoding is performed through a decoding table embedded in the storage device, that is, the sector data address is decoded, and the extracted decoding data is a result obtained by decoding.
Further, in order to verify the decoded result, the byte information before and after decoding may be compared and corrected, specifically, preset byte information of the sector data address may be obtained, the sector data address may be understood as a data address where program damage occurs, the preset byte information may be understood as the first four bytes of the data address where program damage occurs, the converted byte information is the first four bytes of a data overlay address where damage occurs in the decoded result, by determining whether the converted byte information and the preset byte information are consistent, in other words, after initialization is successful, the address of the sector data to be read is transmitted to the hard disk through an instruction, the inside of the hard disk is converted through a decoding table, then response data of the hard disk is read using the instruction, the flag of the conversion success is stored in the data, if the first four bytes of the returned data are addresses previously transmitted to the hard disk, the conversion is successful, otherwise, if the conversion is failed, the two are consistent, a first extraction instruction may be generated, and mirror image extraction of the target firmware data is performed, generally, a mirror image storage form is a type of a file, that is a redundant copy of the same disk. Many files can be made into an image file, and the image file and programs such as GHOST are placed in a disk and are restored into many files after being opened by software such as GHOST, and RAID 1 and RAID 10 use the image. Common image file formats are ISO, BIN, IMG, TAO, DAO, CIF, FCD. That is, by performing a mirror extraction of logical data on the target firmware data, data that has been corrupted by the program can be extracted against an identical copy on another disk.
Further, as shown in fig. 3, step S130 includes:
step S131: determining a data storage threshold value, a data calling threshold value and a data response frequency of the memory to be overhauled according to the target application scene;
step S132: marking the data storage threshold value as a first associated parameter, the data calling threshold value as a second associated parameter and the data response frequency as a third associated parameter;
step S133: collecting historical circulation data of the memory to be overhauled to obtain a historical circulation data set;
step S134: and taking the historical circulation data set as training data, taking the first association parameter, the second association parameter and the third association parameter as comparison identification data, performing comparison training on the training data, and building the data traversal screening model.
Wherein, step S134 includes:
step S1341: carrying out user-defined splitting on the training data to obtain a data training set and a data verification set;
step S1342: training the data training set based on the comparison identification data to generate a preliminary data traversal screening model;
step S1343: inputting the data verification set into the preliminary data traversal screening model, and performing data verification training to generate a first verification result;
step S1344: and optimizing the preliminary data traversal screening model according to the first verification result to generate the data traversal screening model.
Specifically, when the data traversal screening model is set up, specifically, a data storage threshold, a data retrieval threshold, and a data response frequency of the to-be-overhauled memory may be determined according to the target application scenario, where when the target usage scenario is applied to hard disk storage of a notebook computer, the data storage threshold is a size of a maximum capacity storage data space on the hard disk, the data retrieval threshold is a maximum retrieval threshold on the hard disk, the data response frequency is a response rate when the storage data on the hard disk is retrieved, and further, the data storage threshold may be marked as a first association parameter, the data retrieval threshold is marked as a second association parameter, and the data response frequency is marked as a third association parameter.
Meanwhile, historical circulation data of the memory to be overhauled can be collected to obtain a historical circulation data set, the historical circulation data set is the historical circulation data set on the hard disk of the notebook computer, and then the historical circulation data set can be used as training data, and the first correlation parameter, the second correlation parameter and the third correlation parameter are used as comparison identification data to conduct comparison training on the training data.
In the training process, in order to train a relatively accurate data traversal screening model, custom splitting can be performed on the training data to obtain a data training set and a data verification set, wherein the custom splitting can be understood as that the training data is divided in a custom mode according to actual data requirements, one part of the training data is used as the data training set and is used for training the data traversal screening model, and the rest part of the training data is used as the data verification set and is used for verifying the trained model. Specifically, after the user-defined splitting is finished, the data training set can be trained based on the comparison identification data to generate a preliminary data traversal screening model, the preliminary data traversal screening model is a product obtained by performing model training for the first time, and then the data verification set can be input into the preliminary data traversal screening model to perform data verification training to generate a first verification result, the first verification result represents the verification condition of the model training result and an actual production result, and if the first verification result is not matched with the actual production result, the preliminary data traversal screening model can be optimized to generate the data traversal screening model, the data traversal screening model is a model obtained by final training, and a system storage data set can be screened based on the model.
Further, step S660 includes:
step S661: performing mirror image extraction on the logic data of the target firmware data to obtain preset standard sector data of the memory to be overhauled;
step S662: based on the preset standard sector data, carrying out contrast detection on the target firmware data to obtain a first detection difference result;
step S663: and correspondingly overhauling the memory to be overhauled according to the first detection difference result.
Specifically, after the target firmware data is subjected to mirror image extraction of logic data, preset standard sector data of the memory to be overhauled can be obtained, the preset standard sector data is storage data in a standard mirror image file before occurrence of damaged data, the target firmware data is subjected to contrast detection through the preset standard sector data, a first detection difference result is obtained, namely the preset standard sector data is compared according to byte information of a sector data address, actual firmware data of the storage device is contrasted, a data difference represented by the two data differences can be obtained, namely the first detection difference result is obtained, the memory to be overhauled can be correspondingly overhauled on the basis, and quick overhaul of key sector data covered by a chip channel is achieved.
In summary, the method for repairing the firmware of the memory provided by the invention has the following technical effects:
the method comprises the steps of extracting current data of a target memory, obtaining relevant data of a storage medium, screening and marking data of a key sector, obtaining higher maintenance parameters, scanning a service area covered by a current chip channel of the target memory through the maintenance parameters, filtering a specific program of the storage medium of the scanned data, decoding and extracting program running data obtained through filtering, contrasting and detecting extracted standard sector data and actual sector data, determining the defect position of the actual sector data, and timely maintaining.
