Kuyini inkumbulo isilondolozi

Akubona bonke abanikazi computer bazi ukuthi isilondolozi enjalo, nakuba ngenkuthalo esetshenziswa ngokuphelele zonke abakhiqizi, kokubili izilimi kanye nezinhlelo. Abanye abasebenzisi usanda kuphela usuqalile ukuzakhela ikhompyutha siqu, kwesinye isikhathi phezu izinkundla ingxoxo e-Global Network esekhala ukusebenza kancane abasizi babo electronic. Ngokwesibonelo, uma imizuzwana 5 badlule phakathi kokuqala ithegi izinhlelo ehhovisi futhi ukuvela Amafasitela alo, khona-ke ubhekwa isikhathi okukhulu. Noma ezifundazweni 10-15 imizuzwana ayadingeka ivuleke uhlelo lokusebenza kusukela idrayivu kanzima kuya izingqoko kazibuthe - Saze sadlala ngesikhathi. Okumangalisayo: iminyaka nedlanzana kuphela edlule, kwethulwa uhlelo kungathatha cishe kwesigamu somzuzu, futhi lalibhekwa okusheshayo. Enye into icacile - anda computer ukusebenza kakhulu futhi lokhu akuyona indima yokugcina eyadlalwa processor isilondolozi.

Njengoba lisetshenziswe zekhompyutha inkumbulo amamojuli esekelwe dram ubuchwepheshe (inkumbulo ashukumisayo ukufinyelela okungahleliwe). Izici lobu buchwepheshe endaweni eziphansi, enokwethenjelwa futhi ... isivinini iphansana. Dram esetshenziswa eminyakeni eyishumi edlule, nakuba namanje kancane ukulungiswa yayo. Uma ngesikhathi ukufinyelela inkumbulo amaseli imisiwe mayelana 200 nanoseconds ke manje lesi silinganiso enqobe okuvimbelayo NS 20. Kunengqondo - ijubane kufanele kube nje kumnandi! Nokho, ngo parallel ngcono dram lenyuka anoma ibhasi processor, ngakho isilinganiso jikelele ishintshile akunjalo njengoba kungenzeka. Nanku umbuzo yini inqolobane. Ngingayithola kanjani ukwandisa ukusebenza kohlelo subsystem Computer Memory? Impendulo isobala - kungenzeka ukuba esikhundleni akusebenzi dram okuthile ezithuthukayo ezingaphezu. Kodwa elidumile Intel isipiliyoni enamabha ezibizayo Rambus wasikisela ukuba esikhundleni akufanele ukwandisa Kubiza.

Ngaphandle ukugwenywa, akekho ayengeke akucabange ukuthi isilondolozi enjalo, ngoba indlela enjalo wawungeke ube iphuzu kakhulu. Kumanele esikhundleni okuthuthukile dram SRAM (static okungahleliwe inkumbulo ukufinyelela) futhi leyo nkinga ingaxazululwa. Kodwa lokhu Kwakuyohlanganisani nokwanda okuphawulekayo izindleko. Ngakho ngamcela inguqulo ebucayini kwaphumelela kangangokuthi osebenza kusukela esikhathini sokuqala 80286-speed inkumbulo amabhlogo ahlelwe ukwandisa ukusebenza kohlelo phakathi kuqhathaniswa kancane inkumbulo amamojuli kanye ngesivinini processor. Isihlobo elingamathalenta dram cell lemali abangelutho kakhulu, ezisukela 8 kbps (ezingeni L1) kufika ku amashumi wamamegabhayithi (L3 ezingeni). isilawuli Special sidlula a bi Ohlangothi ekusakazeni idatha kanye namakhophi nabo memory okusheshayo. Ngesicelo elilandelayo CPU ukuze amasheke dram isilawuli ukuthi akukho "elivulekile ngomqondo" IDATHA kwesokudla, futhi uma zitholakala, wokugaya ukudluliswa nje isilondolozi. Njengoba singabona, isimiso yokusebenza ulula. kuvela izinkinga izindlela kokusebenza: onjiniyela kudingeke ukuba anqume ukuthi uhlobo idatha impinda, indlela ukuzivuselela, indlela yokuthuthukisa umsebenzi kahle, njll Kodwa lokhu kuba indaba enkulu kakhulu, ngakho ngaphezulu ke ingatholakala kwimithombo ezikhethekile ..

Ngakho, impendulo yombuzo othi lokho kungase memory isilondolozi, kukwazi ukwakhiwa kanje: isilondolozi kuyinto sesikhashana kulo isilawuli ubhala / ofunda idatha, okwandisa ukusebenza kohlelo subsystem inkumbulo.

Futhi ngokuphathelene isicelo inethiwekhi okungukuthi isilondolozi? Isiphequluli umsebenzisi uma ubuka amakhasi ku-intanethi usebenzisa ikhambi efanayo. Lapho kuvulwa lokuqala yimiphi izakhi zawo, Amakhasi amaningi (idatha yesithombe) elondolozwe ku kwifolda phezu disc, futhi okwalandela efinyelela lokhu idatha alulayishiwe kusukela kuwebhu kancane, futhi zifakwe kufolda, ukukhuphula ijubane surfing. Ukusheshisa obonakalayo ikakhulukazi ngesivinini eliphansi Inthanethi.
