The embodiment of the present invention additionally provides the interpretation method of a kind of symbol data, and this interpretation method can be real by the present invention
The code translator that executing example foregoing is provided performs, and the interpretation method provided the embodiment of the present invention below is carried out
Illustrate.
Fig. 2 is the flow chart of interpretation method according to embodiments of the present invention, as in figure 2 it is shown, the method includes following
Step S202 is to step S210:
S202: read and need to carry out multiple code element fragments of the symbol data of ECC decoding, when ECC decodes, by
It is directly proportional in the area cost of decoding and the field capacity size of decoding, it is contemplated that amass cost to time dough-making powder,
Generally can limit the area of decoding, therefore decoding is to carry out according to the code element after being grouped, read is

The syndrome of one code element fragment.
S206: judge whether the element in the syndrome calculated is zero respectively；Correspondingly, can be in step S204
After disposably the syndrome of all code element fragments being calculated, whether the element in each syndrome is zero and enters
Row judges, it is also possible in the decoding flow process carry out a code element fragment to the element in the syndrome of this code element fragment be
No it be zero and judge.
S208: code element fragment corresponding to syndrome that element is not zero proceeds ECC decoding, i.e. to element
Code element fragment corresponding to syndrome not being zero carries out error correction；And
S210: code element fragment corresponding to syndrome that element is zero no longer carries out ECC decoding, i.e. stop unit
Element is the error correction of the code element fragment corresponding to syndrome of zero.
Owing to the decoding process of ECC decoding is generally divided into three phases: the first stage is for calculating syndrome；Second stage
For mistake in computation multinomial；Phase III is Search Error position.Second stage and the 3rd during decoding every time
Time required for stage occupies the ratio of more than half in decoding total time, and occurs during decoding
When special circumstances such as do not have mistake, if still carried out according to common decoding algorithm, then will cause temporal wave
Taking, the code translator of the embodiment of the present invention by whether the element in the syndrome of each code element fragment is zero enters
Row judges, to determine that element is the code element fragment corresponding to syndrome of zero, i.e. determines the code element that there is not mistake
Fragment, and then terminate the error correction to the code element fragment that there is not mistake, thus avoid the code element to there is not mistake to carry out
Check and error correction flow process, it is achieved that reduce workload when symbol data is carried out ECC decoding, solve prior art
The problem that middle ECC interpretation method causes decoding time to waste owing to work decoding amount is big, and then reached to shorten decoding
Time, improve the effect of decoding efficiency.

Executing the interpretation method of example compared with the interpretation method shown in Fig. 2, the two difference is, in the preferred embodiment of the present invention
Interpretation method in also include the element in syndrome is not zero (that is, code element fragment exist needs carry out checking and
The mistake of error correction) position multinomial in number of errors whether more than the judgement of ECC decoding error correcting capability.
Specifically, when each code element fragment is decoded, each code element fragment order, whole decoding in no particular order
As long as the code element fragment decoding that be there is a need to carry out decoding is terminated by process.The syndrome that each code element fragment is corresponding
And error location polynomial corresponding to syndrome can be with one-time calculation, it is also possible in the decoding flow process of a code element fragment
In once calculate, if as it is shown on figure 3, to from i-th (i is positive integer) group code element fragment start decoding, and
And the syndrome of each code element fragment calculates in the decoding flow process of each code element fragment, then the flow process of interpretation method
For: first i-th group of code element fragment is carried out syndrome calculating；Next to that judge in the syndrome of i-th group of code element fragment individual
Whether element is all ' 0 ', through judging, if each element in the syndrome of i-th group of code element fragment is all ' 0 ',
Then skip error location polynomial calculating and the Search Error position multinomial of i-th group, it may be judged whether complete all districts
The ECC decoding in territory, i.e. judges whether there is also the code element fragment not calculating syndrome in symbol data, if it does,
The syndrome then entering i+1 group code element fragment calculates, and circulates by that analogy；If i-th group of code element fragment is adjoint
Each element in formula is not all ' 0 ', then calculate the mistake of i-th group of code element fragment according to the syndrome of i-th group of code element fragment
Position multinomial by mistake, and the error location polynomial of i-th group is scanned for, determine errors present, and to mistake
Whether the number of position judges beyond ECC error correction ability, if i-th group of mistake is overflowed, proving to occur in that can not
The mistake corrected, now proves that the mistake of i-th group of code element fragment occurs in that spilling situation, it is impossible to complete institute vicious
Correct, so time should terminate ECC decoding；When the mistake of i-th group of code element fragment is not overflowed, then can be smooth
Complete the decoding process of i-th group, after completing the decoding of i-th group of code element fragment, it may be judged whether complete all regions
ECC decoding, i.e. judge whether symbol data there is also the code element fragment not calculating syndrome, if it is present
The syndrome entering i+1 group code element fragment calculates, and circulates by that analogy, until decoding terminates.
The interpretation method of the preferred embodiment of the present invention, when code element fragment mistake does not occurs, directly skips errors present many
Item formula calculates and Search Error position, saves the time of more than 50%；Directly jump out when mistake spilling situation occurs
Whole ECC decodes, and saves the decoding time of remaining decoding group, has reached further shortening decoding time, improves
The effect of decoding efficiency.
Preferably, when the number judging errors present decodes error correcting capability beyond ECC, interpretation method also includes raw
Becoming decoding to interrupt report, this content included can be: number of errors exceeds error correcting capability, is not fully complete the information of error correction.
Process interrupt is decoded, to facilitate user to carry out the operations such as false exclusion by generating decoding interruption advisory alarm user.
