Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
One embodiment of the invention provides set top box data storage method, and as shown in Figure 1, concrete steps comprise described method:
In step S101, mark off the first memory block and the second memory block that data storage capacity equates in Flash.
In the present embodiment, the first memory block and the second memory block are all Block, and certain the first memory block and the second memory block, according to different use occasions, can be also other file layouts.
In step S102, the data type size of the data of set top box of storage, divided the data storage capacity of described the first memory block and the second memory block respectively as required, marks off a plurality of data blocks identical with the data type size.
It should be noted that, the data type size refers to the minimized storage space size that data type needs, different data types is different to the data storage capacity demand of data block, according to the data type size, the data storage capacity of the first memory block and the second memory block is divided successively, can be marked off a plurality of data blocks identical with the data type size.If the integral multiple that the data storage capacity of the first memory block and the second memory block is the data type size can be divided fully, otherwise last blocks of data piece and data type vary in size, and gives up.For example, the data storage capacity of supposing the first memory block and the second memory block is all 64K, if the data type size is 8K, the first memory block and the second memory block are respectively by the complete data block that is divided into 8 8K so; If but the data storage capacity of data type corresponding data piece is 9K, namely the data type size is 9K, the first memory block and the second memory block are divided into respectively the data block of 7 9K and the data block of 1 1K so, and the data block of this 1K will be not used in the storage data.
In step S103, when writing the data of set top box that needs storage, determine the current data block of the first memory block and the current data block of the second memory block.
It should be noted that, current data block refers to a rear data block of the data block of storing data, take the first memory block as example, suppose that the first memory block is divided into the data block of 7 9K and 1 1K, if the data block of front 3 9K has all been stored data, but the data block of the 4th 9K is not stored data, the 4th data block is exactly the current data block of the first memory block so, if the data block of 7 9K has all been stored data, and the data block of 1 1K can not be stored the data of the type, the first memory block does not just have current data block so, perhaps being expressed as the first memory block all is fully written, do not write space.
Particularly, realize that the current data block method of determining the first memory block is:
From the start address of the first memory block, according to the data of order read block from left to right;
The data of described data block are carried out to each byte traversal verification;
It is that the data block of 0xff is current data block entirely that verification obtains first.
It should be noted that, take the first memory block describes as example, suppose that from left to right there is A the first memory block, B, C, D, E is totally 5 data blocks, at first the data of read block A, traveled through verification, if it is not the data of 0xff that the data of data block A exist, illustrate in data block A with valid data, the data that continue in read block B are traveled through verification, if it is not the data of 0xff that the data of data block B exist, illustrate that data block B is with valid data, the data that continue in read block C are traveled through verification, if there are not the data that are not 0xff in the data of data block C, illustrate that so data block C is exactly current data block.
In step S104, the current data block of the current data block of the first memory block and the second memory block is hocketed and writes.
Particularly, the method for performing step S104 is specially:
According to controlling data (the English: (English: Index), the data of set top box of needs storage is write to the current data block of the memory block that odd even Index is corresponding of the parity flag Control Data);
When at described odd even Index, corresponding memory block writes described data of set top box, for described data of set top box adds packet header (English: Head), described Head comprises sequence number (English: Identity, be called for short: ID), version (English: Version) and the cyclic redundancy check (CRC) (English: Cyclic Redundancy Check of described data of set top box, be called for short: CRC), described Version equates with the odd even Index in Control Data;
Odd even Index in Control Data is added to 1.
It should be noted that, control data and be stored in internal memory, odd even Index is used for controlling data of set top box and writes which memory block.When odd even Index is even number, the memory block that odd even Index is corresponding is the first memory block, and when odd even Index is odd number, the memory block that odd even Index is corresponding is the second memory block.When the odd even Index in controlling data is even number, data of set top box can be written into the current data block of the first memory block, and then odd even Index adds 1, becomes odd number; When the odd even Index in controlling data is odd number, data of set top box can be written into the current data block of the second memory block, and then odd even Index adds 1, becomes even number, so alternately writes the current data block of the first memory block and the second memory block.When in two memory blocks, also there is no data, odd even Index can be initialized to 0, if this time is in the time of need to writing data of set top box, can write first data block of first memory block, perhaps become the initial data piece of first memory block, after first data block of first memory block is written into data of set top box, odd even Index in Control Data has changed the odd even attribute by add 1 on 0 basis, fashionable when again there being data of set top box to write, can write first data block of the second memory block.Confirmable, by additive method or other parameters, also can control, realization will need the data of set top box of storage alternately to write the first memory block and the second memory block.
With reference to figure 2, Head comprises sign ID, CRC and Version totally 3 fields, and ID fixes, CRC does the value that the CRC32 verification obtains to the data in data block, when data writing, the odd even Index in Control Data is write to Version, so Version equates with odd even Index.
In the present embodiment, by subregion is carried out in two memory blocks, data of set top box is alternately write to the data block of two memory blocks, make when writing new data and need not frequently wipe the data on memory block, guaranteed serviceable life and the utilization ratio of Flash, and alternately two memory blocks are write, even writing fashionable outage, cause the data that newly write on a certain memory block unsuccessful, but data are also preserved in another memory block, can not cause the situation that affects Set Top Box work to occur.
Optionally, described method also comprises:
When the first memory block does not write space, wipe the first memory block, the data of set top box of needs storage is write to the initial data piece of the first memory block;
When the second memory block does not write space, wipe the second memory block, the data of set top box of needs storage is write to the initial data piece of the second memory block.
It should be noted that, while supposing that the first memory block does not write space, while carrying out write operation, wipe the first memory block, data of set top box can be written to first data block of the first memory block, the initial data piece that perhaps is called first memory block is also same reason for second memory block; Wiping the first memory block and do not wipe subregion, is only that the data of set top box of the inside storage is wiped.
Optionally, after described step S104, also comprise:
When Set Top Box restarts, read all data blocks from the first memory block and the second memory block respectively;

Version in the valid data piece is compared, and what the Version value was maximum is valid data piece;
Data of set top box in valid data piece is read in to internal memory;
According to the odd even Index in the Version replacement Control Data in the Head of the data of set top box in described valid data piece;
Wipe the memory block that described odd even Index is corresponding, the data of set top box in described valid data piece is copied to the initial data piece of the memory block that described odd even Index is corresponding;
After described odd even Index is added to 1, wipe the memory block that described odd even Index is corresponding.
It should be noted that, be specially according to the odd even Index in the Version replacement Control Data in the Head of the data of set top box in described valid data piece:
When the Version in Head is odd number, the odd even Index in Control Data is reset to 0, when the Version in Head is even number, the odd even Index in Control Data is reset to 1.
