纯整数运算分块并行Turbo编译码器的FPGA设计 Title:FPGADesignofBlock-basedParallelTurboEncoderforPureIntegerOperations Abstract: Turbocodeshavegainedsignificantattentioninthefieldofcommunicationsystemsduetotheirsuperiorerrorcorrectionperformance.Parallelturboencodingisanefficienttechniquetoacceleratetheencodingprocessbyusingaparallelarchitecture.ThispaperfocusesontheFPGAdesignofablock-basedparallelturboencoderthatperformspureintegeroperations.Theproposeddesignaimstomaximizethroughputwhileminimizingresourceutilization. 1.Introduction: Turbocodesarewidelyusedinmoderncommunicationsystemstoprovidereliabledatatransmissionovernoisychannels.Theturboencodingprocessinvolvestheuseofmultiplecomponentencoderstogenerateredundantbits,whichareaddedtotheoriginaldata.Theseredundantbitsenhanceerrorcorrectioncapabilities. 2.TurboEncodingandParallelism: Turboencodinginvolvesiterationsbetweenmultiplecomponentencoders,knownasconstituentencoders.Eachconstituentencoderoperatesonadifferentinterleavedversionoftheinputdata.Toeffectivelyparallelizetheturbocodingprocess,ablock-basedapproachcanbeemployed.Inthisapproach,inputdataisdividedintoblocks,andeachblockisprocessedindependently.Thisallowsforparallelprocessingofmultipleblocks. 3.PureIntegerOperations: Theuseofpureintegeroperationsintheturboencoderdesignprovidesseveraladvantages,suchasreducedresourceutilization,higherclockfrequencies,andsimplifiedimplementation.Byeliminatingtheneedforfloating-pointarithmetic,thedesignbecomesmoreefficientandsuitableforimplementationonFPGAplatforms. 4.ArchitectureandImplementation: Theproposedblock-basedparallelturboencoderarchitectureconsistsofthreemainblocks:theinterleaver,componentencoders,andinterleavercontroller.Theinterleaverblockperformsblock-wiseinterleavingoftheinputdata,providingmultipleinterleavedversions.Theseversionsarethenprocessedbyeachcomponentencoderinparallel,usingonlyintegeroperations.Theinterleavercontrollermanagestheinterleaverblockandcontrolstheorderofdataprocessing. 5.ResourceUtilizationandThroughputAnalys
