Informatec Digital » Hardware » Ama-Multi-Core processors: Izinzuzo kanye Nokubi

Esikhathini samanje sedijithali, ama-multi-core processors asegcwele yonke indawo ezinhlobonhlobo zemishini kagesi, kusukela kumakhompuyutha edeskithophu namalaptop kuya kuma-smartphone namathebulethi. Lawa maphrosesa, aqukethe ama-cores amabili noma ngaphezulu acutshungulwayo, anikezela ngenani lezinzuzo kanye nokubi okufanele kuhlolwe. Kulesi sihloko, sizohlukanisa izici ezibalulekile zama-multi-core processors, sihlole izinzuzo nemikhawulo yawo, futhi sixoxe ngomthelela wazo ekusebenzeni kwemishini yesimanje kagesi.

Ayini ama-multi-core processors?

Amaprosesa amaningi angama-core angamayunithi okucubungula aphakathi (ama-CPU) aqukethe ama-core amabili noma ngaphezulu ngamanye, ngalinye likwazi ukwenza imisebenzi ngokuzimela. I-core ngayinye isebenza njengeyunithi yokucubungula ephelele, enememori yayo ye-cache kanye namakhono okusebenzisa imiyalelo. La ma-core angasebenza ngesikhathi esisodwa ukwenza imisebenzi eminingi ngasikhathi sinye, athuthukise ukusebenza kwesistimu iyonke futhi enze kube nokusebenza kahle okukhulu ekucubungulweni kwedatha.

Izinzuzo zama-multi-core processors
