1. Uyini umehluko omkhulu phakathi kwe-MCU ne-CPU?
An I-MCU ine-processor, inkumbulo, namathuluzi ku-chip eyodwa. Yenzelwe imisebenzi elula futhi isebenza ngesikhathi sangempela. A CPU iyashesha futhi iphatha izinhlobo eziningi zekhompuyutha. Idinga izingxenye ezengeziwe zenkumbulo nokokufaka/okuphumayo.
Ithiphu: Khetha i I-MCU amagajethi amancane kanye a CPU kumasistimu amakhulu.
2. Kungani ama-GPU engcono kumahluzo kunama-CPU?
Ama-GPU zinezinkulungwane zamacores asebenza ndawonye. Lokhu kubasiza ukuthi bacubungule izithombe, amavidiyo, nama-animation ngokushesha. Ama-CPU inama-cores ambalwa futhi ingcono ukwenza imisebenzi yesinyathelo nesinyathelo, hhayi ukwenza izinto eziningi njengezithombe.
Iqiniso: Ama-GPU futhi ukusiza ukusheshisa ukuhlolwa kwe-AI nesayensi.
3. Kufanele ukhethe nini i-APU esikhundleni se-CPU ne-GPU?
Sebenzisa i I-APU lapho udinga kokubili ikhompuyutha kanye nehluzo ku-chip eyodwa. Zilungele amakhompyutha aphathekayo, amakhonsoli amageyimu, nama-smart TV. Ama-APU yonga indawo namandla, okwenza kube lula futhi kusebenze kahle.
4. Yini eyenza ama-MPU alungele izinhlelo ezithuthukile?
Ama-MPU zinamandla futhi ziyavumelana nezimo. Basebenza ngezingxenye ezengeziwe, okubenza balungele i-AI, izimboni, namadivayisi ahlakaniphile. Ngokungafani Ama-MCU, benza imisebenzi enzima kodwa basebenzisa amandla engeziwe.
5. Iyiphi iyunithi engcono kakhulu kumadivayisi anamandla aphansi?
Ama-MCU ukukhetha okuphezulu kwamadivayisi adinga amandla amancane. Basebenzisa amandla amancane kakhulu futhi banenkumbulo eyakhelwe ngaphakathi namathuluzi. Lokhu kubenza bafanelekele amagajethi e-IoT, amadivaysi ezokwelapha, nezinto zikagesi zasekhaya.
Qaphela: Ngaso sonke isikhathi hlola ukuthi idivayisi yakho idinga amandla angakanani ngaphambi kokukhetha iyunithi.
