Because each communication interface all have employed circulation double-buffering pool technology, following steps only introduce the circulation double-buffering pool technology of wherein a certain communication interface.The step of circulation double-buffering pool technical finesse is adopted to comprise:
31) two Buffer Pools are built.If the peak-peak communication data rate Abps of communication interface, minimum processing unit holding time sheet is Bs, and the initial process memory rate of data is Cbps.If A*B≤C*B, then open up the Buffer Pool that two sizes are (C*B) b, otherwise open up the Buffer Pool that two sizes are (A*B) b.The cooperation principle of two Buffer Pools is: Buffer Pool one is for accepting the high data rate from communication interface, and this part is based on DMA technology (DirectMemoryAccess) and Buffer Pool lock technology.After the data of Buffer Pool one are filled with, Buffer Pool two proceeds data and stores, the now input data that just stored of Data Analysis and processing module process Buffer Pool one, the information flow in conjunction with human-computer interaction interface flows to option, result is stored in corresponding queue with the form of array and goes.After the data processing of Buffer Pool one is complete, then process the data in Buffer Pool two, and the input data of communication interface then be stored in Buffer Pool one are gone.Circulation like this repeatedly.

the incremental time that the complete later discontinuous storage of input data processing brings is
minimum processing unit holding time sheet is T
unit.The time that then new processing unit takies is about:
then a new round for the size of the Buffer Pool stored is:
33) speed of Data Analysis and processing module is adjusted.In step 32) in, if we find that the processing speed of Data Analysis and processing module is less than the data entry rate of communication interface all the time, will cause undyingly increasing progressively for storing Buffer Pool, it is depleted that final result is exactly whole system internal memory.Data Analysis and processing speed must be adjusted, make two Buffer Pools expand dynamically in controlled scope and reduce, reach and utilize minimum overhead to realize protocol conversion and rate matching issue.The method of adjustment has: the parallel plus-minus of Data Analysis and processing module quantity, reduce system unexpected situation (reducing software and hardware to interrupt), improve storage means and reduce unnecessary file read-write operations.
34) according to step 32) in the change curve matching of four factors of influence.Scientific and reasonable matched curve makes circulation double-buffering pool technology play most powerful key.F
