Incazelo yesithombe
Isithombe siyi-infographic ebanzi, egxile endaweni enesihloko esithi "MurmurHash3A Algorithm" eboniswe ngokugqamile phezulu ngombhalo ogqamile, omnyama. Ngaphansi kwesihloko, umdwebo wethula ishadi lokugeleza elisuka kwesobunxele liye kwesokudla kanye nelisuka phezulu liye phansi elichaza ngomqondo ukuthi inqubo ye-MurmurHash3A hashing iguqula kanjani idatha yokufaka ibe umphumela we-hash osayizi ohleliwe. Isitayela sisezingeni eliphezulu ngamabomu futhi singabonakali, sigwema ama-constant aqondile noma imininingwane yokusetshenziswa ngenkathi sisadlulisela isakhiwo sonke se-algorithm.
Ngaphezulu kwesobunxele kukhona ibhokisi eliyindilinga elingunxande elibhalwe ukuthi "Idatha Yokufaka" ngetimu yombala oluhlaza okwesibhakabhaka. Ngaphakathi kwaleli bhokisi, kuboniswa umugqa omfushane wezinombolo ezimbili, omelela ama-bits okufaka angahleliwe. Umcibisholo uhola kusukela kuleli bhokisi uye kwesokudla uye komunye unxande oyindilinga onombala ophuzi obhalwe ukuthi "Thola Ukhiye We-32-bit," okubonisa ukuthi okufakwayo kuqala kucutshungulwa ngezingcezu ukuze kukhishwe okhiye abasebenzayo. Imicibisholo ijiyile futhi imnyama, okwenza ukugeleza kwedatha kube lula ukuyilandela.
Ngaphansi kwendawo yokufaka, kuvela ibhokisi eliphuzi elibhalwe ukuthi "Mix & Rotate", elixhunywe ngomcibisholo obheke phansi kusukela kokufakayo. Leli bhokisi liqukethe izithonjana ezilula ezingokomfanekiso njengophawu lokuhlanganisa, uphawu lokuphindaphinda, kanye nomcibisholo wokujikeleza ogobile, okuphakamisa ukuxubana kwezibalo kanye nokujikeleza kwe-bit ngaphandle kokuzibophezela ekusebenzeni okuqondile. Kusukela kuleli bhokisi eliphuzi, umcibisholo ovundlile ukhomba ebhokisini elilandelayo eliphuzi elibhalwe ukuthi "Multiply & Shift." Leli bhokisi lesibili eliphuzi lihlanganisa izithonjana ezilula zokuphindaphinda kanye nokushintsha kwe-bit, okuqinisa ukuthi idatha iguqulwa kakhulu ekusakazeni i-entropy.
Ngakwesokudla sebhokisi elithi "Multiply & Shift" kukhona ibhokisi elinsomi elibhalwe ukuthi "XOR & Scramble." Lixhunywe ngomcibisholo ovundlile, futhi ingaphakathi lalo liphinde libonise izimpawu ezingabonakali, okuhlanganisa isithonjana esifana ne-XOR nomcibisholo ojikelezayo, okudlulisela umqondo wokuqhubeka nokuxova nokuhlanganisa amanani aphakathi. Ukusetshenziswa njalo kombala—ophuzi ekuxubeni, owolintshi ekuphindaphindeni nasekushintsheni, onsomi we-XOR nasekuxova—kusiza ukuqoqa izinhlobo zokusebenza ezihlobene ngokubonakalayo.
Kusukela ebhokisini elithi "Multiply & Shift", umcibisholo obheke phansi uholela ebhokisini eliluhlaza elibhalwe ukuthi "Finalization" ngesihlokwana esithi "Mix & XOR." Le ndawo imele isigaba sokugcina se-avalanche se-algorithm, lapho isimo sangaphakathi sixutshwa khona okokugcina ukuqinisekisa ukuthi izinguquko ezincane zokufaka zikhiqiza umehluko omkhulu wokukhipha. Umbala oluhlaza uhlukanisa ngokubonakalayo lesi sigaba sokugcina nezinyathelo eziyinhloko zokucubungula umzimba ezingenhla.
Ezansi maphakathi nomdwebo kukhona unxande omkhulu oluhlaza okwesibhakabhaka ozungezayo obhalwe ukuthi "Ukuphuma kwe-Hash okungu-32-bit." Ngaphakathi kwawo, kuboniswa olunye uchungechunge lwezinombolo ezimbili, olumelela inani lokugcina le-hash elikhiqizwa yi-algorithm. Umcibisholo owodwa obheke phansi ovela ebhokisini eliluhlaza "lokuGcina" uxhuma ngqo kuleli bhulokhi lokukhipha, okwenza kucace ukuthi lesi yisigaba sokugcina senqubo.
Sekukonke, ukwakheka kuhlanzekile, kuyalingana, futhi kulula ukuskena, kunesikhala esikhulu phakathi kwamabhokisi nezitayela zemicibisholo ezihambisanayo. Ingemuva limhlophe, liqinisekisa ukungafani okunamandla nezinto ezinemibala. Umdwebo udlulisa umsele womqondo we-MurmurHash3A—kusukela kokufakwayo okungahluziwe, ngokusebenzisa imisebenzi yokuxuba nokuskena ephindaphindwayo, kuya ku-hash yokugcina engu-32-bit—ngaphandle kokuthembela ezintweni ezithile eziphansi noma ezingase zibe namaphutha, okwenza kufanelekele izincazelo zemfundo noma zesethulo.
