Embodiment
Embodiments of the present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, in store-and-forward unit of the present invention, realize the transmission method of 9 bit data bytes and install among the first embodiment that the method for this 9 bit data bytes transmission comprises the steps:
Step S1 deposits front 8 of each 9 bit data bytes in first store byte, the 9th deposits the second store byte in, and successively storage: 9 bit data bytes that in this step, will obtain (comprise producing or receiving and obtain) are stored according to common octet, are convenient to next step processing.Particularly, be exactly that with 9 bit data bytes front 8 and expand to 8 bit data bytes as the second store byte with the 9th bit data as the first store byte, and store successively respectively above-mentioned the first store byte and the second store byte.It is worth mentioning that, in the present embodiment, in storage 9 bit data bytes, its 8 store bytes put in order be the first store byte of first 9 bit data bytes, the second store byte of first 9 bit data bytes, the first store byte of second 9 bit data bytes, the second store byte of second 9 bit data bytes, the 3rd 9 bit data bytes the first store byte ... Deng, by that analogy.
Step S2 specifies 8 store bytes of numerical value expression 9 bit data bytes to be set to a data block, and will be converted to the octet that is less than above-mentioned appointment numerical value or continuous serial data: in this step, a plurality of store bytes of above-mentioned expression 9 bit data bytes are divided into data block, to specify numerical value (for example having represented 16 octets of 89 bit data bytes) 8 store bytes (comprising the first store byte and the second store byte) to be divided into a data block, then, again 16 octets in the data block are converted to 9 octets or a continuous serial data, for the purpose of difference, with unconverted, the octet of 9 bit data bytes of per two expressions is called store byte, and the octet after will changing is called the transmission byte.Why 16 8 store bytes can be converted to 98 in this step and send byte, be that it is significant that a data bit is only arranged because in above-mentioned the second store byte, and other data bit all is insignificant.
Step S3 transmits resulting octet or serial data: in this step, the 9(that obtains in the transmission above-mentioned steps is 16 o'clock at appointment numerical value) individual octet or above-mentioned continuous serial data, these bytes are transmission bytes recited above.
Step S4 receives octet or the serial data that transmits: in this step, receive successively the transmission byte or the serial data that transmit in the above-mentioned steps.
Step S3 is converted to the octet of arranging according to the first store byte, the second store byte with the data of 9 bit data bytes of expression in the octet that receives or the serial data, and store above-mentioned octet: in this step, 98 transmission bytes that receive are carried out the inverse transformation of step S2, obtain 16 8 store bytes, these store bytes represent respectively 89 bit data bytes, 8 the first store bytes are wherein arranged, 8 the second store bytes; In when storage, be equally according to first 9 bit data bytes, second 9 bit data bytes ..., arranged sequentially, and in each 9 bit data bytes, the order according to the first store byte, the second store byte is arranged in order again, has 16 octets.It is worth mentioning that above-mentioned byte number obtains when specifying numerical value take 16, if above-mentioned appointment numerical value is not 16, the numeral of above-mentioned each byte may be inappropriate.
As shown in Figure 2, in first embodiment of the invention, the concrete steps that the data block in the above-mentioned steps forms, sends and receives can further be decomposed into again:
Step S21 arranges the first memory cell and the second memory cell in the data block: in this step, arrange in the above-mentioned data block each and represent the store byte of 9 bit data bytes, in the first embodiment, the order of this arrangements of steps is: first 9 bit data bytes, second 9 bit data bytes, the 3rd 9 bit data bytes ... (above-mentioned appointment numerical value is 16 until the 8th 9 bit data bytes are arranged sequentially, expression has 89 bit data bytes, totally 16 8 store bytes), and in each 9 bit data bytes, again according to the first store byte, the order of the second store byte is arranged in order.It is worth mentioning that in the first embodiment, above-mentioned appointment numerical value can change, concrete condition can be decided according to the situation of processor or buffer memory, for example, can be the even number octet that 16,8 or buffer memory allow.Why being the even number octet, is because each 9 bit data bytes is represented, stored by 2 octets.
Step S22 displacement, make that data join end to end successively in the described memory cell, obtain transmission byte or serial data 8, that fill up data: in this step, data in the store byte after the above-mentioned arrangement are shifted, this displacement is unidirectional, shift forward in the present embodiment, so that no matter be data in which 9 bit data bytes, after through displacement all with on data in 9 bit data bytes join end to end, such result is that the data in the whole data block become one and join end to end, and obtains 98 of filling up data and sends bytes.At step S21) after the array data, it is idle, insignificant in the second store byte in per 28 store byte of 9 bit data bytes of expression 7 data bit being arranged; In this step, exactly with (this 9 bit data is distributed in 2 octets equally or/and significant 9 bit data are shifted in 9 bit data bytes and next 9 bit data bytes between 9 data in 9 bit data bytes (being stored in respectively in two octets), its the second store byte has the data bit of 7 free time equally) so that data are filled up each store byte of 8 or are obtained an end to end continuous data string of order; In this step, be that step-by-step is carried out if send, then only need proceed to significant last position of serial data and get final product, send successively this serial data during transmission; If can only send by octet when sending, the situation that last octet is not filled after the above-mentioned displacement then may appear, when the situation of discontented 8 of last byte occurring, need to it be filled to full 8 bit data with insignificant data, obtain a complete octet.
Step S23 sends above-mentioned byte or serial data: in this step, the byte or the serial data that obtain in the transmission above-mentioned steps, these bytes are to be 9 (byte that the needs that obtain send is certainly less than above-mentioned appointment numerical value) in 16 the situation specifying numerical value, when data trailer, also may occur a data block be less than 16 store bytes situation, the byte that need to send this moment also may less than 9.In the situation of processor and modulator permission, can step-by-step send one by one, also can send one by one by byte.
Step S24 receives above-mentioned byte or serial data, and deposits successively buffer memory in: in this step, receive above-mentioned transmitting element, and according to the sequencing that receives, deposit successively above-mentioned data bit in buffer memory.
Step S25 taking-up front 8 bit data obtain the first store byte, take out the 9th is the second store byte: in this step, from above-mentioned buffer memory, take out successively 8 data bit, deposit successively it in octet, obtain representing the first store byte of 9 bit data bytes; Take out the 9th bit data position, expand to an octet, obtain representing the second store byte of this 9 bit data bytes.
9 of the data cached reaches of step S26: in this step, the data in the buffer memory are shifted forward 9, replenish data removed among the step S25.
Step S27 judges whether the processing of notebook data piece is finished; In this way, execution in step S28; Otherwise, jump to step S25; In the present embodiment, 16 8 store bytes are arranged in the data block, represent 89 bit data bytes, judge that a data block is exactly the number according to these store bytes; If the situation of discontented 16 8 store bytes occurred at the afterbody of transfer of data, it judges that data block processes the whether invalid data bit of appearance in byte of foundation of whether finishing.It is worth mentioning that set in the above-mentioned steps that 16 8 bit data are arranged in the data block is in order to narrate conveniently fully, in fact, the byte number in the above-mentioned data block can be set for example 4 or 16 according to the concrete condition of system.
Step S28 withdraws from: in this step, withdraw from the processing of notebook data piece, prepare to enter the processing of next data block.
Also relate to the device of realizing the transmission of 9 bit data bytes in a kind of store-and-forward unit among the first embodiment, as shown in Figure 3, the device of this 9 bit data bytes transmission comprises: memory module 1, data block form and sending module 2 and data block reception and memory module 3.Wherein, memory module 1 will be stored with two octets successively for each 9 bit data bytes that receives or produce; Per 16 octets that data block forms and sending module 2 is used for storing are converted to 9 octets, and send successively the octet after the described conversion as a data block; Data block reception and memory module 3 are used for receiving successively serial data or the byte of described transmission, the described serial data that receives are carried out the inverse transformation opposite with transmission, become each 9 bit data and take 2 bytes store.

Fig. 4, Fig. 5 illustrate respectively in data block formation in the present invention's the second enforcement, the particular flow sheet that sends and receive and the store-and-forward unit and realize the apparatus structure schematic diagram that 9 bit data bytes are transmitted.As shown in Figure 4, in second embodiment of the invention, the concrete steps that the data block in the above-mentioned steps forms, sends and receives can further be decomposed into again:
Step S41 will represent that 16 8 store bytes of 89 bit data bytes are as a data block, be arranged in order wherein 8 the first store bytes: in this step, data block is 16 octets fixing, and it can only be 16, these 16 octets are obtained by 89 bit data bytes, have namely comprised 8 the first store bytes and 8 the second store bytes; If existing above-mentioned 89 bit data bytes of data deficiencies that will transmit, the part that then lacks no matter be its first store byte or the second store byte, all use insignificant data bit to fill, so that still comprise 16 octets in a data block.Arrange in the above-mentioned data block each and represent the store byte of 9 bit data bytes, in a second embodiment, the order of this arrangements of steps is: the first store byte of the first store byte of first 9 bit data bytes, second 9 bit data bytes, the 3rd 9 bit data bytes the first store byte ..., until the 8th 9 bit data bytes the first store byte is arranged sequentially.It is the odd bytes in above-mentioned 16 octets arranged sequentially.
Step S42 inserts an octet successively with the data in the second store byte in each 9 bit data bytes, obtain the 9th byte: in this step, owing to only have on the data bit meaningful in the second store byte of each 9 bit data bytes of expression, and other data bit all is insignificant, so, data in the second memory cell of 89 bit data bytes are combined, just can obtain the 9th transmission byte of filling up.In merging process, data in the second store byte of first 9 bit data bytes be put into the 7th (item is 6) that data in the second store byte of the 8th (item is 7) of the 9th transmitting element, second 9 bit data bytes are put into the 9th transmitting element ..., the rest may be inferred.It is worth mentioning that (usually appearing at the afterbody of transfer of data) is take insignificant data stuffing as 9 bytes when 9 bytes of data deficiencies.
Step S43 sends above-mentioned 9 bytes: in this step, send successively 9 of obtaining in the above-mentioned steps and fill up bytes data, 8.
Step S44 receives above-mentioned 9 bytes, and deposits successively buffer memory in: in this step, receive above-mentioned 9 and send byte, and put into successively buffer memory by byte.
Step S45 stores front 8 octets respectively as the first store byte of 89 bit data bytes: in this step, 8 of fronts in 9 bytes that receive are assigned as respectively the 1st the first store byte to the 8th 9 bit data bytes in the notebook data piece.
Step S46 expands to the second store byte that a byte also deposits respectively 89 bit data bytes in each data bit of the 9th byte: in this step, according to the rule of putting into the 9th transmission byte among the step S42, each data bit in the 9th byte is expanded to respectively an octet, as the second store byte of 9 bit data bytes of correspondence, until the data in the 9th byte are all distributed; Store above-mentioned the first store byte and the second store byte, finish the processing of notebook data piece.
Also relate to the device of realizing the transmission of 9 bit data bytes in a kind of store-and-forward unit among the second embodiment, as shown in Figure 4, the device of this 9 bit data bytes transmission comprises: memory module 1, data block form and sending module 2 and data block reception and memory module 3.Wherein, memory module 1 will be stored with two octets successively for each 9 bit data bytes that receives or produce; Per 16 octets that data block forms and sending module 2 is used for storing are converted to 9 octets, and send successively the octet after the described conversion as a data block; Data block receives and memory module 3 is used for receiving successively the octet of described transmission, and 9 octets of a described data block that receives are converted to 16 octets and storage.
In a second embodiment, memory module 1 also comprises: front 8 that are used for 9 bit data bytes are stored in first octet and form unit 11 with the first store byte that forms this 9 bit data bytes; Be used for the 9th the second store byte that is stored in second this 9 bit data bytes of this formation of octet of 9 bit data bytes formed unit 12.In a second embodiment, the 9th bit data expands to an octet and is stored in the second store byte.And data block forms and sending module 2 further comprises: being used for per 16 store bytes of described data block is a data block, odd bytes forms 8 octets of data block, the valid data position of even bytes is inserted by the sequencing of its storage in each data bit of the 9th octet becomes 1 byte, and the data block that obtains the serial data that 9 octets form forms unit 24; For the transmitting element 23 that above-mentioned 98 bit data are sent successively.
In a word, by the description of above-mentioned two embodiment, when adopting special chip to realize modulation and demodulation, often running into unit of transfer is the situation of byte, and transmission must be that 8 bit data are as unit of transfer take byte.Can realize efficient transmission by two kinds of methods.To be transmit leg reconfigure 9 bit data streams by displacement a kind of method is the data flow of 8 bit data units, namely the 1st byte of storage becomes the 1st byte of synchronous transmission, the 2nd byte conversion of storage is 1 wherein 7 the 2nd byte of form transmitting with the 3rd byte of storage, the 4th byte conversion of 1 of the residue of the 3rd byte of storage, storage is 1, wherein 6 the 3rd bytes that form transmission of the 5th byte of storage, the like, 16 bytes of storage are transformed to 9 bytes of transmission.The recipient carries out inverse transformation, is stored as two bytes after being reduced to 9 bit data.The advantage of this way is that conversion is on one side transmitted on one side, and data delay is little, and afterbody does not have the transmission of unnecessary byte simultaneously, and channel transport efficiency is high, and is complicated when shortcoming is processing.Another kind method is will store first data take 16 bytes as a data block, transmits after it is transformed to the data block of 9 bytes.Wherein 8 bytes are the 1st, 3,5,7,9,11,13,15 bytes of storing, and another byte is a byte (each store byte is transformed to) that forms after the 2nd, 4,6,8,10,12,14, the 16 byte conversion of storage.The recipient carries out inverse transformation.The advantage of this way is that conversion process is simpler, and shortcoming is just can carry out inverse transformation after the recipient will receive 9 bytes, has increased data delay, and afterbody on average increases the hash of 4.5 bytes, and the front a kind of mode of channel service efficiency is low.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
