（The inverse of frequency, here for illustrating to facilitate direct service life）It it is 20 milliseconds, since 20 greatest common divisor is 20 institutes
Time-out time timer is arranged is 20 milliseconds, when the timer times out after fingerprint image will be directly obtained from fingerprint sensor
It is distributed to the algorithm (referring to fingerprint authentication algorithm).
SS44―2：If currently having turned on the multinomial algorithm for needing to use fingerprint sensor, the value of counter is added
One, image is directly passed to " corresponding algorithm "；" the corresponding algorithm " refers to：1/（t*f’）Aliquot counter
Or alternatively counter can be by 1/（t*f’）The algorithm divided exactly, t are the time-out time set by timer, and f ' is the algorithm
The frequency values of fingerprint image are obtained from fingerprint sensor, counter is the value of counter.
For example, only opening image detection algorithm at present, fingerprint authentication algorithm, they obtain fingerprint from fingerprint sensor
The periodic quantity of image（The inverse of frequency, here for illustrating to facilitate direct service life）Respectively 40 milliseconds, 20 milliseconds, by
In 40,20 greatest common divisor be 20 thus setting timer time-out time be 20 milliseconds.When each timer expiry,
Counter counter is added 1, when this timer expiry, fingerprint image will be obtained from fingerprint sensor and be distributed to " phase
The algorithm answered " is somebody's turn to do " corresponding algorithm " and refers to：" the corresponding algorithm " refers to：1/（t*f’）It can be divided exactly by counter
Algorithm, t is the time-out time set by timer, and f ' is that the algorithm obtains the frequency of fingerprint image from fingerprint sensor
Value, counter are the value of counter.
It is assumed herein that counter=1, for fingerprint authentication algorithm, its frequency is 1/20 khz, and counter=1 can quilt
1/（t*f’）=1/ (20*1/20)=2 is divided exactly or alternatively 1/（t*f’）=1/ (20*1/20)=1 aliquot
Counter=1, therefore give the data distribution to fingerprint authentication algorithm；For image detection algorithm, its frequency is 1/40 khz,
Counter=1 cannot be by 1/（t*f’）=1/ (20*1/40)=2 is divided exactly or alternatively 1/（t*f’）=1/ (20*1/
40)=2 aliquant counter=1, therefore do not give the data distribution to fingerprint authentication algorithm；
It is assumed herein that counter=2, for fingerprint authentication algorithm, its frequency is 1/20 khz, and counter=2 can be by 1/（t*
f’）=1/ (20*1/20)=2 is divided exactly or alternatively 1/（t*f’）=1/ (20*1/20)=1 aliquot counter=
2, therefore give the data distribution to fingerprint authentication algorithm；For image detection algorithm, its frequency is 1/40 khz, counter=2
It can be by 1/（t*f’）=1/ (20*1/40)=2 is divided exactly or alternatively 1/（t*f’）=1/ (20*1/40)=2 aliquot
Counter=2, therefore give the data distribution to fingerprint authentication algorithm；
It is assumed herein that counter=3, for fingerprint authentication algorithm, its frequency is 1/20 khz, and counter=3 can be by 1/（t*
f’）=1/ (20*1/20)=2 is divided exactly or alternatively 1/（t*f’）=1/ (20*1/20)=1 aliquot counter=
3, therefore give the data distribution to fingerprint authentication algorithm；For image detection algorithm, its frequency is 1/40 khz, counter=3
It cannot be by 1/（t*f’）=1/ (20*1/40)=2 is divided exactly or alternatively 1/（t*f’）=1/ (20*1/40)=2 cannot
Divide exactly counter=3, therefore does not give the data distribution to fingerprint authentication algorithm.
Compared with prior art, for the still above example, image detection algorithm, both fingerprint authentication algorithms are required for from fingerprint
Data are obtained at sensor, must be obtained twice, and the method for this case then need to only obtain once.This case be equivalent to each algorithm with
An intermediate station is established between fingerprint sensor, and finger print data is uniformly obtained by intermediate station and is distributed to each fingerprint correlation calculation again
Method.The prior art then without this intermediate station, is directly connected with fingerprint sensor respectively by each fingerprint related algorithm, each
Fingerprint related algorithm is mutual indepedent between each other, and data are obtained directly from fingerprint sensor, keep the number of acquisition data more.
Such as in this case, when assuming that when counter=2, for fingerprint authentication algorithm, its frequency is 1/20 khz, counter=2 energy
By 1/（t*f’）=1/ (20*1/20)=2 is divided exactly or alternatively 1/（t*f’）=1/ (20*1/20)=1 aliquot
Counter=2, therefore give the data distribution to fingerprint authentication algorithm；For image detection algorithm, its frequency is 1/40 khz,
Counter=2 can be by 1/（t*f’）=1/ (20*1/40)=2 is divided exactly or alternatively 1/（t*f’）=1/ (20*1/40)
=2 aliquot counter=2, therefore give the data distribution to fingerprint authentication algorithm；The method of this case herein only needs to pass from fingerprint
A data are obtained at sensor, and the prior art obtains two algorithms and obtains data from fingerprint sensor respectively, it altogether will be twice.
