Area；The target matrix that the areas RAM import is sent to host by data/address bus.
Wherein, all tables of data of optical module are stored in the areas FLASH of optical module, and target matrix continues for host
The tables of data taken.
Data/address bus can be I2C (Inter-Integrated Circuit) bus, and I2C buses are by Philips public affairs
A kind of simple, bidirectional two-line synchronous serial bus of department's exploitation, it only needs the device that both threads can be on being connected to bus
Information is transmitted between part, host and optical module can be communicated by I2C buses.
In a kind of realization method, target matrix is determined from the areas FLASH of optical module, including：
Optical module after the power is turned on, the default data table in the areas FLASH is determined as target matrix；
It, will after detecting the data table numbering that host is written by data/address bus at the default identification byte in the areas RAM
The tables of data with obtained data table numbering is determined as target matrix in all tables of data of the areas FLASH storage.
Wherein, default data table is preset for giving tacit consent to the data for importing the areas RAM in all tables of data in the areas FLASH
Table, data table numbering are used for unique identification data table.
Some tables of data can be selected as default data table from all tables of data in the areas FLASH in advance, for example, can be with
In advance in tables of data, the tune-up data table of optical module manufacturer internal, calibration data table, offset data table as defined in selection agreement etc.
One or more as each default data table.
Specifically, the every data table size stored in the areas FLASH can be identical, and store needed for all default data tables
Storage total capacity can be equal to the size in the areas RAM, after the areas Gu RAM size is determining and every data table size determines, acquiescence
The sum of tables of data can determine.For example, the size in the areas RAM is 256 bytes, the size of every tables of data is 128 bytes, then writes from memory
It is 2 to recognize tables of data, if the size in the areas RAM is 512 bytes, the size of every tables of data is 128 bytes, then default data table is
4.
As can be seen that optical module after the power is turned on, default data table can directly be imported into the areas RAM of optical module, therefore give tacit consent to
Tables of data is to be imported into the tables of data of optical module at first.
Theoretically, the areas RAM can correspond to a storage address by byte addressing, each byte, and the byte in the areas RAM is got over
More, the memory space in the areas RAM is bigger.Specifically, a byte can be set from each byte in the areas RAM in advance as default
Identification byte, host can be counted as tables of data by the data that data/address bus is written at the default identification byte in the areas RAM
Number, and the tables of data number-mark is host tables of data to be read, it is thus possible to all numbers that the areas FLASH are stored
It is determined as target matrix according to the tables of data with obtained data table numbering in table.
In a kind of realization method, the areas RAM may include default fixed area and default multiplexing area, and target matrix is directed into
The areas RAM of optical module, including：
When target matrix is default data table, a part of target matrix is imported to the default fixed area of optical module,
Another part target matrix is imported to the default multiplexing area of optical module；
When target matrix for tables of data with the data table numbering obtained when, target matrix is directed into default
It is multiplexed area.
Default fixed area can be preset low byte area in the areas RAM, and it can be preset height in the areas RAM to preset multiplexing area
The efficiency that target matrix is directed into default multiplexing area is improved in byte regions in order to reduce the occupancy to default multiplexing area, pre- to be marked with
Character learning section may be in default fixed area.
In addition, in order to improve the read-write efficiency of data, every data table size in the areas FLASH is identical, and every data
The size of table is the greatest common divisor of default fixed area size and default multiplexing area's size, for example, default fixed area size and pre-
If multiplexing area's size is respectively：128 bytes and 384 bytes, since 128 and 384 greatest common divisor is 128, then every data
Table size can be 128 bytes.
The I2C mailing addresses of optical module are A0/A2, and host can once access the number of 256 bytes by the addresses A0/A2
According to, therefore in order to save the space in the areas RAM, the production cost of optical module is saved, the size in the areas RAM can be 256 byte addresses, when
So, in other embodiment, the size in the areas RAM may be 512 bytes, 382 bytes etc., the present invention to the size in the areas RAM not
It limits.
The areas RAM are segmented into multiple regions, do not limit the size in each region, for example, the size in each region can
Think 128 bytes, 256 bytes etc..
Specifically, when the size in the areas RAM is 256 bytes, the size in each region is 128 byte, the areas RAM are segmented into
2 pieces of regions, the areas Di Ban (the 0th~127 byte) and the areas Gao Ban (the 128th~255 byte), and can be using the areas Di Ban as default
Fixed area, using the areas Gao Ban as default multiplexing area, using the 127th byte of default fixed area as default identification byte；For another example, when
When the size in the areas RAM is 512 bytes, the size in each region is 128 byte, the areas RAM are segmented into 4 pieces of regions, each region
Bytes range be respectively：0th~127 byte, the 128th~255 byte, the 256th~383 byte, the 384th~511 byte, and
And it can be using the 0th~127 byte as default fixed area, the 128th~255 byte, the 256th~383 byte, the 384th~511 word
Section presets multiplexing areas as three, and using the 127th byte of default fixed area as default identification byte.
In a kind of realization method, a part of default data table is imported to the default fixed area of optical module, another part is write from memory
Recognize the default multiplexing area that tables of data imports optical module, including：
According to data table numbering from small to large/sequence from big to small, each default data table is imported successively default solid
Determine area, it, will not imported default data after the total size of imported default data table is equal to the size of default fixed area
Table imports default multiplexing area successively.
Each default data table all has data table numbering, to illustrate according to the sequence of data table numbering from small to large
Illustrate, for example, the data table numbering of default data table is respectively 1,2,3,4, the size of every default data table is 128 bytes,
The size of default fixed area is 128 bytes, and the size for presetting multiplexing area is 384 bytes, the then data for being first 1 by data table numbering
Table, which imports, presets fixed area, and the tables of data that data table numbering is 2,3,4 is then imported default multiplexing area successively.
In another implementation, target matrix is directed into the areas RAM of optical module, including：
Determine target matrix the areas FLASH storage address, according to preset RAM regional address and FLASH regional address
Correspondence imports address using the corresponding RAM regional address of identified storage address as target, target matrix is directed into
Target imports address.
For each tables of data in the areas FLASH, it can determine the tables of data in the storage address in the areas FLASH, sheet
Invention does not limit method of determination, for example, can utilize default corresponding between data table numbering and the areas FLASH storage address
Relationship determines the corresponding areas the FLASH storage address of target data table numbering, using the identified areas FLASH storage address as mesh
Storage address of the mark tables of data in the areas FLASH.
For example, target matrix is stored in the third page (areas FLASH are stored by page) in the areas FLASH, according to preset
The third page of the correspondence of RAM regional address and FLASH regional address, the areas FLASH corresponds to the 128th~255 byte in the areas RAM, then
Address is imported using the 128th~255 byte in the areas RAM as target, and target matrix is imported to the 128th~255 word in the areas RAM
Section.
In a kind of realization method, the corresponding areas RAM of each default data table can also be previously set and import address, for every
One default data table can directly obtain the corresponding default areas RAM of the default data table and import address, and by the default data table
It is directed into the corresponding default areas RAM of the default data table and imports address, a part of target matrix is imported into optical mode to realize
Another part target matrix is imported the default multiplexing area of optical module by the default fixed area of block.
S102, after having detected data write-in RAM areas, judge whether that the areas FLASH are written in the data that the areas RAM will be writtens,
If it is, the areas data write-in FLASH that the areas RAM will be written.
It is understood that when data are written to optical module by data/address bus in host, optical module can detect
RAM areas are written in data, in turn, it can be determined that whether will be written the areas data write-in FLASH in the areas RAM, it, can in a kind of realization method
, to judge whether that the areas data write-in FLASH in the areas RAM will be written in the following way：
When starting timer, whether detection still has the areas data write-in RAM in preset timing duration；
If it is, the areas data write-in FLASH in the areas RAM will be written in judgement；
If it is not, then the areas data write-in FLASH in the areas RAM will be written in judgement.
Timing duration can be previously set, such as can be 250 milliseconds, 300 milliseconds, 400 milliseconds etc., in preset meter
In Shi Shichang, if having detected the areas data write-in RAM again, showing host, there is still a need for data, host and light is written to optical module
Data communication between module should not be interrupted, and communication between host and optical module can be interrupted by writing data into the areas FLASH,
Therefore in order to keep the data between host and optical module to communicate, loss of data is reduced, it is possible to determine that the number in the areas RAM will not be written
According to the areas write-in FLASH；In preset timing duration, if detecting the areas no data write-in RAM, show host temporarily without to
Data are written in optical module, and the data communication between host and optical module can be interrupted, therefore can be determined that will be written the number in the areas RAM
According to the areas write-in FLASH.
In order to simplify deterministic process, and the areas FLASH are successfully write data into, in a kind of realization method, will in judgement
After the areas data write-in FLASH in the areas RAM are written, method can also include：Reset timer restarts timing, and return executes inspection
Whether survey still has the step of areas RAM are written in data in preset timing duration.
It can restart timing by reset timer, and return to whether still execution detects in preset timing duration
There is the step of areas RAM are written in data, to realize simplified deterministic process, and can be in detection in preset timing duration
After there is no the areas data write-in RAM, the areas data write-in FLASH in the areas RAM will be written, realize the persistence of data.
In order to economize on resources, in a kind of realization method, the FLASH is written in the data that the areas RAM will be written in judgement
Qu Hou, the method further include：
