Chipset

Chipset (Chipset) ke karolo ea mantlha ea boardboard mme hangata e arotsoe ka lichifi tsa Northbridge le Southbridge chips ho latela tlhophiso ea tsona ho board ea mama.The Northbridge chipset e fana ka ts'ehetso bakeng sa mofuta oa CPU le maqhubu a mantlha, mofuta oa memori le bokhoni bo phahameng, li-slots tsa ISA / PCI / AGP, tokiso ea phoso ea ECC, joalo-joalo.Chip ea Southbridge e fana ka tšehetso bakeng sa KBC (Keyboard Controller), RTC (Real Time Clock Controller), USB (Universal Serial Bus), Ultra DMA/33(66) mokhoa oa ho fetisa data oa EIDE, le ACPI (Advanced Power Management).The North Bridge chip e bapala karolo e ka sehloohong 'me e boetse e tsejoa e le Host Bridge.

Chipset le eona e bonolo haholo ho e tseba.Nka Intel 440BX chipset, mohlala, chip ea eona ea North Bridge ke Intel 82443BX chip, eo hangata e leng holim'a lebokose la li-motherboard haufi le CPU slot, 'me ka lebaka la mocheso o phahameng oa mocheso, heatsink e kentsoe chip ena.Chip ea Southbridge e haufi le ISA le PCI slots 'me e bitsoa Intel 82371EB.Li-chipsets tse ling li hlophisitsoe ka mokhoa o ts'oanang.Bakeng sa li-chipsets tse fapaneng, ho boetse ho na le phapang ea ts'ebetso.

Li-chips li se li le hohle, 'me lik'homphieutha, liselefouno le lisebelisoa tse ling tsa digital li fetoha karolo ea bohlokoa ea lesela la sechaba.Lebaka ke hobane litsamaiso tsa sejoale-joale tsa likhomphutha, likhokahano, tlhahiso le lipalangoang, ho kenyeletsoa le Marang-rang, kaofela li itšetlehile ka boteng ba lipotoloho tse kopaneng, 'me ho hola ha li-IC ho tla lebisa katlehong e kholo ea thekenoloji, ka bobeli mabapi le theknoloji ea moralo le ho latela maemo. katleho ea lits'ebetso tsa semiconductor.

Chip, e bolelang sephaphatha sa silicon se nang le potoloho e kopaneng, ka hona lebitso chip, mohlomong e ka ba lisekoere-mithara tse 2.5 feela ka boholo empa e na le li-transistors tse limilione tse mashome, athe li-processor tse bonolo li ka ba le li-transistors tse likete tse kentsoeng ka har'a chip limilimithara tse 'maloa. sekwere.Chip ke karolo ea bohlokoa ka ho fetisisa ea sesebelisoa sa elektroniki, se etsang mesebetsi ea likhomphutha le polokelo.

Ts'ebetso ea moralo oa li-chips tse fofang holimo

Ho thehoa ha chip ho ka aroloa ka mekhahlelo e 'meli: moralo le tlhahiso.Mokhoa oa ho etsa chip o tšoana le ho haha ​​​​ntlo e nang le Lego, e nang le li-wafers e le motheo, 'me ka mor'a moo e arola holim'a likarolo tsa ts'ebetso ea tlhahiso ea chip ho hlahisa IC chip e lakatsehang, leha ho le joalo, ntle le moralo, ha ho na thuso ho ba le bokhoni bo matla ba ho etsa tlhahiso. .

Ts'ebetsong ea tlhahiso ea IC, li-IC hangata li reriloe ebile li entsoe ke lik'hamphani tsa meralo tsa IC, tse kang MediaTek, Qualcomm, Intel, le baetsi ba bang ba tsebahalang ba ka sehloohong, ba iketsetsang li-chips tsa bona tsa IC, ba fana ka litlhaloso tse fapaneng le lisebelisoa tsa ts'ebetso bakeng sa bahlahisi ba tlaase. ho khetha ho tloha.Ka hona, moralo oa IC ke karolo ea bohlokoahali ea ts'ebetso eohle ea ho theha chip.
