Information storage means, by NOR FLASH log file numbers during specific implementation, the information of file, when a system is powered up, automatically
The initial logical address of load document number information and last file, stops logical address, originates pipelining-stage, stops stream
Water level and stopping Page addresses etc., so that and then Nandflash array control units can be recorded next time, realize text
The operations such as the read-write wiping of part, not only the saving record time, simplify the efficiency of the operations such as operation, and the read-write wiping of raising file.
The content of the invention
The present invention provides a kind of file information storage method of Nandflash arrays, with highly versatile, is easy to implement
Feature, has broad application prospects.
Concrete scheme proposed by the present invention is：
A kind of file information storage method of Nandflash arrays：
Log file number information is read from specified NOR FLASH addresses by NOR FLASH controllers, is loaded into
Nandflash array control units, the information of last file is loaded to Nandflash antenna array controls according to file record number
Device,
The start information that Nandflash array control units determine to record next time according to the information of last file, when
Nandflash array control units receive start recording order, and stream is started by the start information of last obtained file
Water is stored,
Record is completed, NOR FLASH controllers more new file number, while being recorded this according to current file number information
Start information write NOR FLASH corresponding address.
The start information includes the initial logical address of last file, stops logical address, originates pipelining-stage, stops
Only pipelining-stage, Page addresses.
The start logical that Nandflash array control units determine to record next time according to the information of last file
Location, originates pipelining-stage, and stops relation and Page address of the pipelining-stage with starting pipelining-stage by loading, determines next text
The initial logical address of part, originates pipelining-stage, originates Page, carries out flowing water storage.
If the stopping pipelining-stage of the loading is equal to starting pipelining-stage and Page addresses are 0, of next file
Beginning logical address is the stopping logical address of loading, and starting pipelining-stage is the stopping pipelining-stage of loading, and starting Page is 0, otherwise
Initial logical address adds 1 to stop logical address, and starting pipelining-stage is the stopping pipelining-stage of loading, and starting page is 0.
It is described when Nandflash array control units receive erasing order, Nandflash array control units complete all
After Nandflash BLOCK erasings, NOR FLASH controllers more new file number is 0, simultaneously erased NOR FLASH records text
The corresponding SECTOR of part information.
When Nandflash array control units receive reading file command, NOR FLASH according to the file index of reading, from
The initial logical address of file is read in NOR FLASH, pipelining-stage is originated, stops logical address, stops pipelining-stage, stops Page
Information completes the read operation of file to Nandflash array control units.
Usefulness of the present invention is：
The invention provides a kind of file information storage method of Nandflash arrays, by NOR FLASH controllers from specifying
NOR FLASH addresses read log file number information, Nandflash array control units are loaded into, according to file record
Number loads the information of last file to Nandflash array control units,
The start information that Nandflash array control units determine to record next time according to the information of last file, when
Nandflash array control units receive start recording order, and stream is started by the start information of last obtained file
Water is stored,
Record is completed, NOR FLASH controllers more new file number, while being recorded this according to current file number information
Start information write NOR FLASH corresponding address；
By NOR FLASH log file numbers during specific implementation, the information of file, when a system is powered up, automatic load document
The initial logical address of number information and last file, stop logical address, originate pipelining-stage, stop pipelining-stage and
Stop Page addresses etc., so that and then Nandflash array control units can be recorded next time, realize the read-write of file
The operation such as wiping, not only the saving record time, simplifies the efficiency of the operations such as operation, and the read-write wiping of raising file.
Brief description of the drawings
Fig. 1 the inventive method schematic flow sheets.
Embodiment
The present invention provides a kind of file information storage method of Nandflash arrays, by NOR FLASH controllers from finger
Log file number information is read in fixed NOR FLASH addresses, Nandflash array control units is loaded into, according to file record
Number loads the information of last file to Nandflash array control units,
The start information that Nandflash array control units determine to record next time according to the information of last file, when
Nandflash array control units receive start recording order, and stream is started by the start information of last obtained file
Water is stored,
Record is completed, NOR FLASH controllers more new file number, while being recorded this according to current file number information
Start information write NOR FLASH corresponding address.
With reference to accompanying drawing, the present invention will be further described.
Comprised the following steps that using the inventive method：
First, when a system is powered up, NOR FLASH controllers read log file number letter from specified NOR FLASH addresses
Breath, is loaded into Nandflash array control units,
If wherein file record number is 0, fileinfo is not loaded with, upper electric LOAD processes terminate；Otherwise remembered according to file
Record number loads the start information of last file, comprising initial logical address, stops logical address, originates pipelining-stage, stops
Only pipelining-stage, stops the information such as Page addresses to Nandflash array control units；
The start logical that then, Nandflash array control units determine to record next time according to the information of last file
Location, originates pipelining-stage；
If wherein the stopping pipelining-stage of loading is equal to starting pipelining-stage and Page addresses are 0, the starting of next file is patrolled
Stopping logical address of the address for loading is collected, starting pipelining-stage is the stopping pipelining-stage loading, and starting Page is 0, is otherwise originated
Logical address adds 1 to stop logical address, and starting pipelining-stage is the stopping pipelining-stage of loading, and starting page is 0；
Then, when Nandflash array control units receive start recording order, the start logical obtained using upper step
Location, originates pipelining-stage, starting Page starts flowing water storage, after the completion of record, NOR FLASH controllers more new file number,
The initial logical address for simultaneously being recorded this according to current file number information, originates pipelining-stage, stops logical address, stops
Only pipelining-stage, stops the information such as Page addresses and writes NOR FLASH corresponding address.
In the storing process of the fileinfo of above-mentioned Nandflash arrays, when Nandflash array control units receive wiping
During except order, Nandflash array control units are completed after whole Nandflash BLOCK erasings, and NOR FLASH controllers are more
New file number is 0, the corresponding SECTOR of simultaneously erased NOR FLASH log file information；
Also, when Nandflash array control units receive reading file command, NOR FLASH according to the file index of reading, from
The initial logical address of file is read in NOR FLASH, pipelining-stage is originated, stops logical address, stops pipelining-stage, stops Page
Etc. information to Nandflash array control units, so as to complete the read operation of file.
Using the present invention realize Nandflash arrays fileinfo storage and realize file read-write wipe etc. operation,
The record time is saved, simplifies operation, the efficiency of the operations such as the read-write wiping of file is improved.
