The action of storage card 50~53 then, is described.The operation of recording of general storage card at first, is described.
Generally, the flash memory that is built in storage card is made of a plurality of erase blocks, implements erasing move with erasure block unit under the situation of obliterated data.Erase block comprises a plurality of record blocks, and wiping the erase block of finishing can write with record block unit.
For example, constitute in the flash memory of erase block the algorithm the when data that write-once constituted 2 record blocks of erase block only write a record block again in record block by 2 512 bytes with reference to figure 6 (a)~(d) explanation.
Among Fig. 6 (a), the 61, the 62nd, erase block.Erase block 61 is made of 2 record block 61a, 61b, and erase block 62 is made of 2 record block 62a, 62b.In addition, among Fig. 6 (a), write data A, B in erase block 61, erase block 62 has been wiped and has been finished.
In the flash memory of the state of Fig. 6 (a) only during overwriting data B, according to following steps.At first, in wiping the erase block of finishing 62, write the data B (NEW) (with reference to figure 6 (b)) of rewriting.Then, move to erase block 62 (with reference to figure 6 (c)) with in erase block 61, writing the data A that finishes.Then, erase block 61 is wiped (with reference to figure 6 (d)).
These sequence of operations are called are involved in formula and preserve.Having taken place to be involved under the situation of formula preservation, owing to taking place to write for 2 times, so the writing rate step-down.In addition, upgrade owing to record the physical location of data, thus except above-mentioned action, also need be when being involved in the formula preservation at every turn the correlation table of new logical addresses and physical address more.
At this, Fig. 7 illustrates the concept map of the storage card of present embodiment use.
The storage card 50~53 that present embodiment is used is (at Fig. 7 illustration storage card 50) as shown in Figure 7, and 1 erase block 71 is made of 32 record blocks 72.The size of each record block 72 is 512B, and the size of erase block 71 is 16KB.
For example, if to record block 72 additional #0, #1, #2 ... serial number, then the record block of #0~#31 becomes 1 erase block.
If to the also additional serial number of erase block 71, then the serial number R (n) of record block 72 becomes following relation with the serial number E (n) of erase block 71.
E(n)=R(n)/32
Because erase block 71 is made of a plurality of record blocks 72, therefore, 2 kinds of patterns take place when for example writing the 16KB data in continuous record block, promptly (1) (example: record block #0~#31), (2) cross over 2 erase blocks record 16KB data conditions (example: record block #1~#32) with the situation of data record to 1 erase block of 16KB.
Under the situation of the pattern of above-mentioned (1), record is moving to be undertaken by 3 steps of following (a1)~(a3).
(a1) check out Unrecorded erase block,
(a2) data of the 16KB that record upgrades in the erase block of being checked out by above-mentioned (a1),
(a3) wipe the preceding data of renewal.
On the other hand, under the situation of the pattern of above-mentioned (2), operation of recording is undertaken by 8 steps of following (b1)~(b8).
(b1) check out Unrecorded erase block,
(b2) the corresponding data of record in the record block #1~#31 of the erase block of checking out by above-mentioned (b1),
(b3) data of preservation corresponding record piece #0 in the erase block of checking out by above-mentioned (b1),
(b4) wipe the erase block that records the record block #0~#31 before upgrading,
(b5) check out Unrecorded erase block
(b6) data of record corresponding record piece #32 in the erase block of checking out by above-mentioned (b5),
(b7) data of preservation corresponding record piece #33~#63 in the erase block of checking out by above-mentioned (b5),
(b8) wipe the erase block that records the record block #32~#63 before upgrading.
As mentioned above, when new data more, bring into play the conveying function of storage card, it is very important that the erase block of considering to aim at (alignment) storage card writes down.
Therefore, in the present embodiment, transmit data from photography portion 1 to recording portion 2, in recording portion 2, the data of 64KB are divided into the 16KB and the record of the erase block of corresponding each storage card with 64KB unit.
Fig. 2 is the block diagram of an example of internal structure of the recording portion 2 of presentation graphs 1.Among Fig. 2, to omitting explanation with piece with Fig. 1 same numeral.Among Fig. 2, the 40th, the temporary transient storage, the 41st, the memory controller of control buffer storage 40 from the buffer storage of the numerical data of interface portion 3 transmission.The digital data conversion that memory controller 41 will for example be imported with the transfer rate serial of 16MB/sec is 4 string digital data strings with transfer rate of 4MB/sec.The 42nd, address transition portion will be converted to the storage card number that is attached to 4 storage cards 50~53 and the address of storage card inside through the sector number of the sector of interface portion 3 indication record-playbacks.The 43rd, according to the storage card control part of 4 storage cards 50~53 being controlled by the internal logic sector number of address transition portion 42 outputs.
More specifically explanation has the action of the recording portion 2 of above structure.
In the present embodiment, interface portion 3 is used the interface of following the PC card.In interface portion 3, send command set and the numerical data of following the ATA specification from photography portion 1.Generally, numerical data is to be the unit of integral multiple of the sector of units chunk with 512 bytes, transmits between recording equipment and main frame.In the present embodiment, numerical data as 1 grouping, is transmitted with 64KB (512B * 32 * 4) unit in 32 * 4 sectors.Like this, the piece that will compile a plurality of sectors is called bunch (cluster), carries out file management with bunch unit in file system (for example FAT).In the present embodiment, carry out file management, carry out data with 4 bunches of units (64KB) and transmit with bunch unit of 16KB.
Fig. 3 illustrates the sequential of input and output bunch of the control part 4 of present embodiment.
Fig. 3 (a) be sent to interface portion 3 bunch sequential chart, label is bunch number.The byte number that sends 1 bunch to is the 16K byte, and the clock synchronization ground of per 4 bytes and 66MHz transmits.
In the DVCPR050 specification, transfer rate is 9MB/sec, is 9/ (66 * 4) so transmit the occupation rate of data.In the present embodiment, in the signal processing part 11 of photography portion 1, in memory (not shown), after the buffered data, be sent to recording portion 2 continuously with 4 bunches of units (16KB * 4).
Fig. 3 (b) be send to storage card 0 bunch sequential chart, (c) of this figure be send to storage card 1 bunch sequential chart, (d) of this figure be send to storage card 2 bunch sequential chart, (e) of this figure be send to storage card 3 bunch sequential chart, note the label of (b), (c), (d), (e) corresponding to note (a) bunch number.
To send the buffer storage 40 of control part 4 by each bunch that per 2 byte 66MHz speed send interface portion 3 to the sequential shown in Fig. 3 (a), and utilize memory controller 41 shown in (b), (c) of Fig. 3, (d), (e), to interweave like that and send storage card control part 43 to sector unit.
In address transition portion 42, will be through interface portion 3 indication bunch number be converted to the storage card number of storage card 50~53 and inner tuft that each storage card has number.
Fig. 4 be address transition portion 42 utilize bunch number conversion table.To send bunch number (transmission of Fig. 4 bunch number) remainder of interface portion 3 to as the storage card number divided by 4.Promptly be expressed as
Storage card number=transmission bunch number %4.
Wherein, " % " is the remainder operation symbol.
In addition, transmit bunch number divided by 4 merchant's integer part as storage card bunch number.Promptly be expressed as
Storage card bunch number=transmit bunch number/4.
Wherein, "/" at this is the oeprator of asking merchant's integer part.
Storage card control part 7 will be as described above bunch number sends 4 storage cards 50~53, per 4 bunches of parallel each storage cards that record by buffer storage 40 parallelizations to bunch according to 42 conversions of address transition portion.
Like this, by cutting apart with the erasure block unit of storage card 50~53 from the data that photography portion 1 is transmitted, parallel recording in the storage card 50~53, the conveying function of can not can lose the storage card of recording rate 4MB/sec, 4 are moved concurrently, can realize the dominant record speed of 16MB/sec.
More than illustrated and to have cut apart and to have recorded the example of each storage card through the data that interface portion 3 transmits with erasure block unit, below as the example of modified embodiment of the present embodiment explanation with record block unit's partition data and record.
Fig. 8 is the key diagram of modified embodiment of the present embodiment.As shown in Figure 8, in this example, will cut apart with the record block unit of flash memory and record each storage card through the data that interface portion 3 transmits.
That is, the data that will transmit through interface portion 3 by each record block (512B) segmentation (stripe) of flash memory to each storage card.In addition, from photography portion 1 with the block unit (64KB) of 4 times of sizes of erase block to recording portion 2 transmitted image data.
In this example, because the erase block of each flash memory is consistent with the data block that transmits from photography portion 1, so as a result of can not preserve the data that can high-speed record transmit from photography portion 1.
In addition, in this example, not only can high-speed record, and when reading, can also read storage card so that 4 times of units of record block are parallel, so can read the data of smaller piece at a high speed.
In addition, when being divided into 4 storage cards, when the data of record 512B, rewrite 4 record blocks with the unit littler (for example 128B) than record block (512B).Therefore, compare with the situation of cutting apart 4 storage cards with 512B unit, number of rewrites increases 4 times, is disadvantageous for the limited flash memory of number of rewrites as can be known.
In addition,, when the flash memory of the inner parallel work-flow N of storage card (N is the integer 2 or more), carry out operation of recording, can carry out high-speed record by N times block unit with the erase block of corresponding flash memory at the built-in a plurality of flash memories of storage card.
The data flow of the reproducing movement of present embodiment is opposite with operation of recording.
At first, read bunch number in interface portion 3 input.Above-mentioned read bunch number by address transition portion 42 be converted to the storage card number that should read and storage card bunch number.Storage card control part 43 according to said memory card number and storage card bunch number, read the numerical data of this bunch from predetermined storage card.The numerical data that reads from storage card temporarily stores into after the buffer storage 40, through interface portion 3 outputs.
Since be input to interface portion 3 bunch number with the starting cluster that reads number form input with the number of clusters that reads continuously, so storage card control part 43 can read bunch and sends buffer storage 40 to from 4 storage cards are parallel, so can make and read high speed.
The signal processing part 11 of the photography portion 1 that bunch is input to that reads.Signal processing part 11 reverts to image data with packed data, outputs to monitor etc.
In addition, reproduce operation and also can in camera recorder, implement, but, then can unload recording portion 2 and insert personal computer, and reproduce the signal of video signal of taking from camera recorder if realize recording portion 2 with PC card shape.
Like this, if recording portion 2 is embodied as the PC card, the new workflow of broadcasting station then can be provided, that is: carrying mobile personal computer and camera recorder photographs in the open air, take off the recording portion 2 of PC card shape and insert the mobile personal computer from camera recorder, after in the mobile personal computer, shot image data being edited, send the broadcasting center to through means of communication such as internets.
In addition, do not need to make transfer rate identical, get final product with high speed upload with the recording rate of signal of video signal to PC.
In addition, because the recording portion 2 of PC card shape does not have the movable structure of machinery, so can be used as more than the more impact-resistant displacement disc of HDD by efficient, flexible as the external record medium of PC yet.In addition, recording portion 2 also can be a rod shape except the card shape.
Fig. 5 illustrates with PC card shape and constitutes recording portion 2, has inserted the concept map of a plurality of camera recorders.As shown in Figure 5, if camera recorder is the structure that can insert a plurality of recording portion 2, then can realize the record of the signal of video signal of longer time.
In addition, if two recording portion 2 are installed on camera recorder, the recording portion of being failure to actuate by exchange then can be carried out the unconfined recording occurring continuously of picture signal.
In addition, present embodiment has illustrated the example of structure with 4 storage cards, but the present invention is not limited thereto certainly, also can have the individual storage card of N (N is a natural number), according to its storage card number of correspondence and the internal logic sector number of address transition portion N storage card be controlled.
As mentioned above, by constituting camera recorder, can realize two-forty record-playback signal of video signal by recording portion that makes a plurality of storage card concurrent activities and photography portion.
In addition,, carry out record accordingly with each storage card, control, can realize good conveying function by record block, the erase block of corresponding stored card with above-mentioned by carrying out piecemeal with predetermined unit according to the characteristic of the storage card that constitutes recording portion.
In addition, by with the N of the record block of flash memory doubly (N is a natural number) carry out piecemeal, and carry out record accordingly with each storage card with above-mentioned, can prevent that number of rewrites from increasing.
In addition, by with the N of the erase block of flash memory doubly (N is a natural number) carry out piecemeal, carry out record with above-mentioned accordingly with each storage card, prevent to use a plurality of storage cards and the erasing times that causes increases, as a result of can carry out high-speed record.
