RISC vs CISC processor
RISC thiab CISC yog cov khoos phis tawj tsim los rau cov khoos phis tawj. Qhov sib txawv ntawm RISC thiab CISC yog qhov tseem ceeb rau kev nkag siab tias lub computer ua raws li koj cov lus qhia. Cov no feem ntau nkag siab tsis zoo thiab tsab xov xwm no npaj siab qhia lawv lub ntsiab lus thiab cov ntsiab lus tom qab ob lub ntsiab lus.
RISC
Hais tau zoo ib yam li RISK, nws yog cov lus luv luv rau Txo Cov Kev Qhia Teeb Meem Computer. Nws yog hom microprocessor uas tau tsim los ua cov lus qhia ob peb zaug tib lub sijhawm. Txog xyoo 1980 cov tuam txhab kho vajtse tau sim tsim CPU uas tuaj yeem ua tiav ntau cov lus qhia ntawm tib lub sijhawm. Tab sis tus qauv tau thim rov qab thiab cov neeg tsim khoom tau txiav txim siab los tsim cov khoos phis tawj uas muaj peev xwm ua tiav cov lus qhia tsawg heev. Cov lus qhia yooj yim thiab tsawg, CPU's tuaj yeem ua tiav lawv sai. Lwm qhov zoo ntawm RISC yog kev siv cov transistors tsawg dua ua rau lawv pheej yig los tsim.
Features of RISC
– Xav tau kev txiav txim tsawg dua
– Uniform instruction set
– Cov hom phiaj dav dav zoo ib yam siv rau hauv txhua lub ntsiab lus
– hom chaw nyob yooj yim
– Tsawg dua hom ntaub ntawv hauv kho vajtse
CISC
CISC sawv cev rau Cov Lus Qhia Ua Kom Yooj Yim Siv Lub Computer. Nws yog qhov tseeb CPU uas muaj peev xwm ua tau ntau yam haujlwm los ntawm ib qho kev qhia. Cov haujlwm yooj yim no tuaj yeem thauj khoom los ntawm kev nco, ua haujlwm lej thiab lwm yam.
Features of CISC
– Cov lus qhia nyuaj
– Ntau tus lej ntawm qhov chaw nyob
– Cov raj xa dej siab heev
– Ntau hom ntaub ntawv hauv hardware
Lub sijhawm dhau los, cov ntsiab lus RISC thiab CISC tau dhau los ua qhov tsis muaj txiaj ntsig vim tias ob qho tib si RISC thiab CISC tau dhau los ua qhov hloov pauv thiab qhov sib txawv ntawm ob tau nce mus ua qhov muag plooj nrog ob qho tib si siv hauv tshuab computer. Ntau ntawm RISC chips niaj hnub no txhawb ntau cov lus qhia raws li nag hmo CISC chips. Muaj CISC chips siv tib cov txheej txheem uas tau txiav txim siab ua ntej siv rau RISC chips nkaus xwb. Txawm li cas los xij, qhov sib txawv ntawm ob qho yooj yim nkag siab thiab muaj raws li hauv qab no.
Hais txog qhov sib txawv, RISC tso lub nra rau cov neeg tsim software vim lawv yuav tsum tau sau ntau kab rau tib txoj haujlwm. RISC yog pheej yig dua CISC vim tias tsawg dua transistors xav tau. Kev ceev ntawm lub khoos phis tawj kuj tseem siab dua nrog cov lus qhia tsawg dua kom ua raws li tib lub sijhawm.
