Imibuzo Evame Ukubuzwa

Iyini isethi yemiyalelo ye-ARM64 futhi kungani ukuyibona ngeso lengqondo kubalulekile?

I-ARM64 (ephinde ibizwe ngokuthi i-AArch64) isethi yemiyalelo engu-64-bit esetshenziswa kuma-smartphones amaningi esimanje, amaphilisi, futhi ngokwandayo kumaseva namadeskithophu afana ne-Apple Silicon Macs. Ukuyibona ngeso lengqondo kusiza onjiniyela nabafundi baqonde amaphethini ombhalo wekhodi, ukuqoqwa kwekhodi ye-opcode, nokuthi iziqondiso zakhiwe kanjani ezingeni elibili - okwenza izinhlelo ezisezingeni eliphansi kanye nokulungisa iphutha kube lula nakakhulu.

Ubani ozuza kakhulu ngokuqonda izakhiwo ze-ARM64?

Onjiniyela bamasistimu ashumekiwe, onjiniyela abahlanganisayo, onjiniyela abahlehlayo, nabacwaningi bezokuphepha bazuza kakhulu. Kodwa-ke, noma yimuphi unjiniyela osebenza eduze kwehadiwe noma othuthukisa ukusebenza kwekhodi ebalulekile uthola inzuzo. Abafundi abafunda i-architecture yekhompuyutha baphinde bathole izethulo ezibonakalayo zibalulekile ekubambeni ukuthi amaphrosesa anquma kanjani futhi asebenzise imiyalelo kahle.

Ihluke kanjani i-ARM64 kokuthi x86-64 ekubhalweni ngekhodi kwemiyalo?

I-ARM64 isebenzisa umbhalo wekhodi weziyalezo wobude obumisiwe obungu-32-bit, ikwenze kujwayeleke kakhulu futhi kube lula ukukubona uma kuqhathaniswa nombhalo wekhodi we-x86-64 wobude obuguquguqukayo (1–15 bytes). Lokhu kufana kwenza ukuqoshwa kwamakhodi kube lula, kuthuthukisa ukusebenza kahle kwamapayipi, futhi kwenza ukubonwa kwephethini kumamephu abonakalayo kube nesakhiwo kakhulu. Kuyisizathu esisodwa sokuthi i-ARM64 ithandwa kumiklamo eyonga amandla.

Ngingafunda kuphi okwengeziwe mayelana nezihloko ezifana ne-ARM64 kanye nezinhlelo zamasistimu ezisezingeni eliphansi?

Amabhulogi obuchwepheshe, amamanuwali ereferensi yezakhiwo, nezinkundla zokufunda ezikhethiwe yizindawo ezinhle kakhulu zokuqala. I-Mewayz inikeza amamojula angu-207 amboza izinhlelo zezinhlelo, ukwakheka kwekhompuyutha, nezihloko ezihlobene ngo-$19/mo kuphela - ihlinzeka ngokuqukethwe okuhlelekile, okujulile okuvala igebe phakathi kolwazi lwethiyori kanye nokwenza, ukuqonda ngokusebenza ngezandla kwemiqondo yezinga eliphansi lekhompuyutha.
