U32 const rtbTable[] = {0, 473195, 504333, 520860, 550000, 700000, 750000, 830000}

622

scale等于62减tableLog

623

step等于div_u64 - unsigned 64bit divide with 32bit divisor*@dividend: unsigned 64bit dividend*@divisor: unsigned 32bit divisor* This is the most common 64bit divide and should be used if possible,* as many 32bit archs can optimize this variant better than a full

624

vStep等于1ULL左移scale减20位

625

stillToDistribute等于1左移tableLog位

627

largest等于0

628

largestP等于0

629

lowThreshold等于total右移tableLog位

631

以s小于等于maxSymbolValue 循环

632

如果count[s]恒等于total则返回:0

634

如果count[s]恒等于0则

635

normalizedCounter[s]等于0

636

继续下一循环

638

如果count[s]小于等于lowThreshold则

639

normalizedCounter[s]等于负1

640

stillToDistribute自减

641

否则

642

proba等于count[s]乘step右移scale位

643

如果proba小于8则

644

restToBeat等于vStep乘rtbTable[proba]

645

proba加等于count[s]乘step减proba左移scale位的值大于restToBeat

647

如果proba大于largestP则largestP等于proba, largest等于s

649

normalizedCounter[s]等于proba

650

stillToDistribute减等于proba

653

如果负stillToDistribute大于等于normalizedCounter[largest]右移1位则

655

errorCode等于Secondary normalization method.To be used when primary method fails.

656

如果Error Management 则返回:errorCode

658

否则normalizedCounter[largest]加等于stillToDistribute
