Ngokubanzi, ekuphela kwezinto ezintsha esizibonayo kwinkqubo yokusebenza zezo zinento yokwenza nezinto ezibonakalayo, kwaye zihambela phambili kancinci, ezo zinokuqondwa ngokusebenza kunye nokuguquguquka kwe-smartphone. Nangona kunjalo, kukho iindaba ezibaluleke ngakumbi kunezo, ezifana naleyo inokufika kwakamsinya, ebizwa ngokuba yi-Optimizer.
Iqabane elitsha le-ART
I-ART yeza ne-KitKat, ibe lixesha elitsha lokuqhuba elaliza kuqhuba izicelo zeJava. Wayeza kwenzeka ukuba athathe indawo kaDalvik, into awayeyifumana kwiLollipop. Nangona kunjalo, enyanisweni yonke into ihamba ngakumbi kunokutshintsha nje umatshini wenyani. Kukwakho into engumqokeleli, enoxanduva "lokusetyenzwa" kwekhowudi ukuyiphumeza. Nge-Dalvik, umqambi wayeluhlobo lwe-JIT (nje-ngexesha), kwaye yayijongene nokuqulunqa nje ngexesha apho ikhowudi yayiza kusetyenziswa. NgeLollipop ukuhlanganiswa kwaba yi-AOT (ngaphambi kwexesha), kwaye iqulunqa ikhowudi ngaphambi kokuba uyisebenzise. Akukho mfuneko yokuchaza ukuba kutheni le nto ilula ukusebenza kwezicelo. Nangona kunjalo, ingxaki kukuba ukuququzelela utshintsho ukusuka eDalvik ukuya kwi-ART, inguqulo ye-AOT ye-Dalvik JIT compiler, ebizwa ngokuba yi-Quick, isetyenziswe. Uhlengahlengiso kulowo wangaphambili, ukuze athethe. Ngoku nantso into eza kutshintsha.
Bulisa kwi-Optimizer
Umqokeleli omtsha ngewakhiwe ukusuka ekuqaleni, kwaye zombini i-ARM kunye noGoogle bebesebenza kuyo. Iza kubizwa ngokuba yi-Optimizer, kwaye iya kuba neetekhnoloji zokuhlanganisa zangoku, kunye nokuhambelana nokuqulunqwa kwamabhithi angama-32 kunye nama-64. I-ARM inoxanduva lwecandelo le-64-bit, ngelixa i-Google inoxanduva lwe-32-bit. Kuyo nayiphi na imeko, kubonakala ngathi enye yezinto ezintsha ziya kuba nakho ukuhlaziya umqokeleli othe wachazelwa ngezinto ezintsha, ngoko ke i-priori sinethemba lokuba iya kuphucula ngokuhamba kwexesha. Kungakhathaliseki ukuba kunjalo, eyona nto iphawulekayo kukuba i-Optimizer iya kuba ngumqokeleli owenziwe ngokuchanekileyo ngenjongo yokuba ngumqambi wezicelo zeJava ze-Android kunye ne-ART njengomatshini wenyani, ngoko sinokulindela ukuphuculwa kokusebenza kunye nokusebenza. yee-smartphones, into ehlala yamkelekile.
