Umthelela wememori kumakhompyutha wezimboni
2024-02-27
Ngokuthuthuka okuqhubekayo kwe-Industrial automation Technology, ukusetshenziswa kwamakhompyutha okulawula izimboni ezikhampandeni emikhakheni ehlukahlukene sekubanzi ngokwengeziwe. Kodwa-ke, umthelela wememori kumakhompyutha wezimboni awunakunakwa ngesikhathi sokusetshenziswa. Le ndatshana izohlola umthelela wememori kumakhompyutha wokulawula izimboni ezivela ezicini zohlobo lwememori, usayizi wememori kanye nesivinini sememori.
1. Umthelela wohlobo lwememori kumakhompyutha wezimboni
Uhlobo lwememori lunomthelela obalulekile ekusebenzeni nasekuzinzweni kwamakhompyutha wezimboni. Njengamanje, izinhlobo zememori ezisetshenziswayo ezisetshenziswayo zifaka i-DDR, DDR2, DDR3, njll. Imemori yazo, i-DDR Memory inezinzuzo zesivinini esikhulu sokudlulisela kanye ne-bandwidth enkulu, kepha ngasikhathi sinye, inokusebenzisa amandla aphezulu nezindleko. Uma kuqhathaniswa ne-DDR, i-DDR2 ne-DDR3 Memory inokusebenzisa amandla aphansi kanye nokuqina okuphezulu, okwenza kusetshenziswe kabanzi kumakhompyutha wezimboni.
Ngaphezu kwalokho, ezincwadini ezithile zekhompyutha zezimboni, imemori ye-ECC nayo ingasetshenziswa njengezinketho. Imemori ye-ECC uhlelo lwememori olunokutholwa kwephutha nomsebenzi wokulungisa, ongathuthukisa ngempumelelo ubuqotho nokwethenjwa kwedatha, ikakhulukazi efanelekile ukunemba kwemininingwane ephezulu.
2. Umthelela wosayizi wememori kumakhompyutha alawulwa yizimboni
Ubukhulu bememori buthinta ngqo ukusebenza kanye nemisebenzi yamakhompyutha okulawula izimboni. Ngokuvamile, umthamo omkhulu wememori ungathuthukisa isivinini sokusebenza kanye namandla okucubungula amakhompyutha alawulwa yizimboni. Lapho ubhekene nemisebenzi eyinkimbinkimbi noma amanani amakhulu emininingwane, amakhompyutha okulawula izimboni anenkumbulo eyanele yememori angasebenza kahle futhi anciphise i-lag.
Ngaphezu kwalokho, kwabanye amakhompyutha alawulwa yizimboni abadinga ukusebenzisa imisebenzi eminingi noma izinhlelo ngasikhathi sinye, umthamo omkhulu wememori ungathuthukisa namandla ayo okucubungula amaningi, ukuze ukusebenzisana kahle phakathi kwemisebenzi kungafinyelelwa.
3. Umthelela wesivinini sememori kumakhompyutha okulawula izimboni
Ngaphezu kwezinhlobo zememori nosayizi, ijubane lememori libuye libe yinto ebalulekile ethinta ukusebenza kwamakhompiyutha wezimboni. Ngokuvamile, ukushesha ijubane lememori, ukushesha impendulo kanye nokucubungula umthamo wamakhompyutha wezimboni. Lapho ubhekene nenani elikhulu lemininingwane noma imisebenzi eyinkimbinkimbi, uma ijubane lememori lihamba kancane, ikhompyutha yezimboni ingahle idlule kuLag noma ukubambezeleka, okuzothinta ukusebenza kwayo okujwayelekile.
Ngaphezu kwalokho, ezincwadini ezithile zokulawula izimboni ezidinga ukuphendula ngesikhathi sangempela, ukuqina kwesivinini sememori nakho kubaluleke kakhulu. Uma i-Memory Speed iguquguquka kakhulu, kungathinta ukunemba nokusebenza kwangempela kwedatha, ngaleyo ndlela kuthinte ukuqina kohlelo lonke lwezimboni.
4. Ekuphetheni
Ngamafuphi, umthelela wememori kumakhompyutha wokulawula izimboni uboniswa ikakhulukazi ngohlobo lwememori, usayizi wememori kanye nesivinini sememori. Ukuze uthuthukise ukusebenza nokuqina kwamakhompyutha wezimboni, kuyadingeka ukuthi ukhethe izinhlobo ezifanele zememori namakhono ngokuya ngezidingo zangempela zohlelo lokusebenza, futhi uqinisekise ukuqina kanye nokwethenjwa kwesivinini sememori. Ngasikhathi sinye, kufanele futhi unake isikhumba kanye nokuhambisana kwememori ukuze ithuthukiswe kalula noma ithathelwe indawo ekuthuthukisweni okuzayo noma ekunwebiseni.
Namuhla, ngokuthuthukiswa okuqhubekayo kwezobuchwepheshe bezimboni ezenzakalelayo, izinkambu zohlelo lokusebenza zamakhompiyutha ezimbonini ziya ngokuya zibanzi, futhi izidingo zokusebenza nokuqina nazo ziyanda. Ngokukhetha uhlobo lwememori olufanele, umthamo kanye nesivinini, kungathuthukisa ngempumelelo ukusebenza nokuqina kwamakhompiyutha okulawula izimboni, ngaleyo ndlela kuthuthukiswe ukuthuthukiswa kanye nokusetshenziswa kobuchwepheshe bezenzeli bezimboni.
