Posungira pamtima Kodi

Si onse eni kompyuta mukudziwa kuti posungira zimenezi, ngakhale kuti amagwira ntchito ndi mwamtheradi opanga onse, mapurosesa ndi mapulogalamu. Ena amene angoyamba kukhala kompyuta munthu, nthawizina pa maonekedwe zokambirana mu Global Network amadandaula ntchito pang'onopang'ono wa omuthandizira awo amagetsi. Mwachitsanzo, ngati masekondi 5 padutse chiyambi cha mapulogalamu ofesi opatsidwa ndi zikamera wa mawindo ake, ndiye amaona kuti nthawi yopambana. Kapena zigawo zimene masekondi 10-15 ndi zofunika jombo ya opaleshoni dongosolo kwa litayamba yovuta kwa platters maginito - akungotaya nthawi. Chodabwitsa: zaka khumi zapitazo, kukhazikitsidwa kwa dongosolo angayambane pafupifupi theka yokha, ndipo ankaona kudya. Chinthu chimodzi ndi bwino - kuchuluka ntchito kompyuta kwambiri ndipo zimenezi si otsiriza ntchito za purosesa posungira.

Monga ntchito zigawo kukumbukira hardware kompyuta zochokera DRAM luso (zazikulu kukumbukira mwachisawawa kupeza). Features njira imeneyi mu mtengo wotsika, mkulu kudalirika ndi ... ndi wotsika liwiro. DRAM ntchito zaka khumi zapitazo, ngakhale kuti anali adakali pang'onopang'ono zosintha ake. Ngati pa nthawi yopempherera kwa maselo kukumbukira mochedwerapo 200 nanoseconds, ndiye tsopano mtengo uwu wagonjetsedwa chotchinga 20 NS. Zingaoneke - liwiro akhale monga wosangalatsa! Komabe, limodzi ndi kusintha kwa DRAM komanso kuchuluka mphamvu basi purosesa, kotero chiŵerengero chonse chasintha si monga momwe ndikanathera. Apa tafika pa funso la chimene posungira lapansi. Kodi ndingatani kuwonjezera ntchito ya subsystem Computer Memory? yankho ndi lodziwikiratu - n'zotheka m'malo lotha DRAM chinachake kwambiri patsogolo. Koma wathuwu Intel zinachitikira ndi mipiringidzo mtengo Rambus ankatanthauza kuti m'malo sayenera kwambiri pa mtengo weniweni.

Popanda lamulo ili, palibenso wina n'komwe kuti posungira zimenezi, chifukwa limagwirira ngati sangakhale mfundo zambiri. Yokwanira m'malo patsogolo kwambiri DRAM SRAM (malo amodzi mwachisawawa kukumbukira mwayi) ndi vuto kuti kuthetsedwa. Koma ndinkaona zikuphatikizapo kuwonjezeka kwambiri mtengo. Chotero ine akufuna kukondera Baibulo bwino kwambiri moti likukhudza kuchokera nthawi ya woyamba midadada kukumbukira 80286-liwiro imakonzedwa kuonjezera ntchito za dongosolo pakati pa zigawo ndi wosakwiya kukumbukira ndi mkulu-liwiro purosesa. Poyerekeza ndi kuchuluka kwa maselo DRAM ndi zonyozeka kwambiri ndalama, kuyambira 8 kbps (mlingo L1) mpaka makumi megabytes (L3 mlingo). Mtsogoleri Special umadutsa ndi zina kuti adzipeza mbali deta mtsinje ndi magazini a iwo mu kukumbukira kudya. Pa pempho lotsatira CPU kwa macheke DRAM Mtsogoleri ngati palibe "anasiya" DETA bwino, ndipo ngati angapezeke kufala purosesa ndi chabe posungira. Monga mmene taonera, mfundo opaleshoni ndi wosavuta. Mavuto mu njira kukhazikitsa: kutukula zoti mtundu deta ndi chibwereza, mmene zosinthika iwo, mmene kusintha ntchito dzuwa, etc. Koma ili ndi mutu waukulu kwambiri, makamaka a angapezeke magwero apadera ..

Choncho yankho la funso la chimene posungira kukumbukira, akhoza anakonza motere: posungira ndi gawo lotetezedwa limene Mtsogoleri analemba / limati deta, kuwonjezera ntchito ya kukumbukira subsystem.

Ndipo yokhudza ntchito zopezera kuti ndi posungira? Osatsegula wosuta pamene kuonera masamba pa Intaneti pogwiritsa ntchito njira yomweyo. Pamene kutsegula loyamba aliyense wa zanyengo, masamba ambiri (deta image) kusungidwa mu chikwatu pa chimbale, ndi wotsatira accesses deta si yodzaza kuchokera pa intaneti pang'onopang'ono, ndipo anaikapo mu fodayi, kuwonjezeka kukasambira liwiro. Mofulumira makamaka noticeable imathamanga otsika Intaneti.
