Google tau tshaj tawm tias Android ib puag ncig rau qhov tsis ntev los no tau tshaj tawm Pixel 7 thiab Pixel 7 Pro smartphones tau raug tshem tawm tag nrho cov cai los txhawb 32-ntsis apps. Cov qauv no yog thawj cov khoom siv hauv Android los txhawb kev siv 64-ntsis nkaus xwb. Nws tau thov tias kev tshem tawm cov khoom siv los txhawb 32-ntsis cov kev pabcuam, uas tau thauj khoom txawm tias 32-ntsis cov kev pabcuam tau pib lossis tsis tau, tau txo qhov kev siv RAM ntawm 150MB.
Qhov kawg ntawm kev txhawb nqa rau 32-ntsis cov kev pab cuam kuj muaj qhov cuam tshuam zoo rau kev ruaj ntseg thiab kev ua haujlwm - cov txheej txheem tshiab ua kom tiav 64-ntsis code sai dua (txog 25%) thiab muab cov cuab yeej tiv thaiv kev khiav dej num (CFI, Control Flow Integrity), thiab nce nyob rau hauv qhov chaw nyob ua rau nws muaj peev xwm ua kom cov efficiency ntawm xws li kev tiv thaiv xws li ASLR (chaw nyob qhov chaw randomization). Tsis tas li ntawd, cov tuam txhab lag luam muaj peev xwm ua kom muaj kev hloov kho tshiab los ntawm kev tshem tawm 32-ntsis kev sim thiab siv cov qauv Linux kernel tsim (GKI).
