A method of it effectively can reduce the resource utilization of main control chip, and reduces and occur with the stochastic source of privately owned communication protocol
The cost that device is communicated causes user experience bad and problem at high cost.
The present invention provides a kind of processing methods of random number, and the method includes the following steps:
Micro-control unit is set, and micro-control unit is connect with main control chip and randomizer respectively, microcontroller list
Member obtains the random number that the randomizer occurs in real time, and carries out pretreatment to the random number and supply the main control chip
Directly read use.
Preferably, the random number is divided into multiple groups, exclusive or is carried out to the random number in described group and generates the first sequence
Column.
Preferably, it detects whether the random number in the First ray has randomness, has randomness then to described the
One sequence carries out displacement and generates the second sequence, and carries out exclusive or to second sequence and obtain processing result to the end；It is on the contrary then pick up
It takes the original random number progress sequence in the First ray to upset and supplement random number and forms third sequence.
Preferably, whether the random number detected in the third sequence has randomness, has randomness then by described the
Multiple random numbers in three sequences are inserted into respectively in multiple described groups, on the contrary then delete the third sequence.
Preferably, the micro-control unit is connected with the main control chip by I2C bus or SPI interface.
Preferably, the micro-control unit by the communication protocol of randomizer described in I/O port analog with it is described
Randomizer connection is communicated.
The present invention adds micro-control unit on mainboard, and micro-control unit obtains the random of randomizer generation in real time
Number, and random number is pre-processed and directly reads use for main control chip；Present invention employs micro-control unit simulation is random
The privately owned communication protocol of number generator and carry out standard interface conversion, at the same the inside of micro-control unit to read with
Machine number carries out corresponding algorithm process, can according to actual needs using different algorithm or data processing method to data into
It is available to main control chip use after row pretreatment, the resource of main control chip is greatly saved, is saved in embedded device
The resource of main control chip can improve user experience well, while avoid having saved cost using programmable logic device,
And it due to can flexibly pre-process random number using algorithm, can be needed to update micro-control unit at any time according to client
Firmware realize pretreatment to data, saved cost, while function modoularization can be made, weight do not had to for hardware design
Multiple design, can add according to actual needs or customizing functions can be completed in removing module；Realization saves main control chip
Resource improves user experience to the greatest extent.
