Chipset

Lub chipset (Chipset) yog lub hauv paus tseem ceeb ntawm lub motherboard thiab feem ntau muab faib ua Northbridge chips thiab Southbridge chips raws li lawv cov kev npaj ntawm lub motherboard.Lub Northbridge chipset muab kev txhawb nqa rau CPU hom thiab lub ntsiab zaus, hom kev nco thiab lub peev xwm siab tshaj plaws, ISA / PCI / AGP slots, ECC kev kho yuam kev, thiab lwm yam.Lub Southbridge nti muab kev txhawb nqa rau KBC (Keyboard Controller), RTC (Lub Sijhawm Sijhawm Clock Controller), USB (Universal Serial Bus), Ultra DMA / 33 (66) EIDE cov ntaub ntawv hloov chaw, thiab ACPI (Advanced Power Management).Lub North Choj nti ua lub luag haujlwm tseem ceeb thiab tseem hu ua Host Bridge.

Lub chipset kuj yooj yim heev los txheeb xyuas.Siv lub Intel 440BX chipset, piv txwv li, nws lub North Choj nti yog Intel 82443BX nti, uas feem ntau yog nyob rau ntawm lub motherboard ze ntawm lub CPU qhov, thiab vim yog lub siab kub tiam ntawm nti, lub heatsink yog haum rau lub nti no.Lub Southbridge nti nyob ze ntawm ISA thiab PCI qhov thiab muaj npe hu ua Intel 82371EB.Lwm cov chipsets tau teeb tsa hauv qhov tseem ceeb tib txoj haujlwm.Rau cov chipsets sib txawv, kuj muaj qhov sib txawv ntawm kev ua haujlwm.

Chips tau dhau los ua txhua yam, nrog cov khoos phis tawj, xov tooj ntawm tes, thiab lwm yam khoom siv digital dhau los ua ib feem tseem ceeb ntawm kev sib raug zoo ntaub.Qhov no yog vim hais tias niaj hnub suav, kev sib txuas lus, kev tsim khoom, thiab kev thauj mus los, suav nrog Is Taws Nem, txhua yam nyob ntawm qhov muaj nyob ntawm kev sib xyaw ua ke, thiab kev loj hlob ntawm ICs yuav ua rau muaj kev lag luam loj hlob mus tom ntej, ob qho tib si ntawm kev tsim thev naus laus zis thiab hauv cov ntsiab lus. ntawm kev sib tsoo hauv cov txheej txheem semiconductor.

Ib nti, uas yog hais txog cov silicon wafer uas muaj cov kev sib xyaw ua ke, yog li lub npe nti, tej zaum tsuas yog 2.5 cm square loj tab sis muaj kaum lab ntawm transistors, thaum cov txheej txheem yooj yim yuav muaj ntau txhiab tus transistors etched rau hauv nti ob peb millimeters. square.Lub nti yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv hluav taws xob, ua haujlwm ntawm kev suav thiab khaws cia.

Cov txheej txheem tsim chip ya siab

Kev tsim cov nti tuaj yeem muab faib ua ob theem: tsim thiab tsim khoom.Cov txheej txheem ntawm kev tsim chip zoo li tsim lub tsev nrog Lego, nrog wafers ua lub hauv paus thiab tom qab ntawd txheej txheej ntawm cov txheej txheem chip tsim los tsim cov IC chip xav tau, txawm li cas los xij, tsis muaj kev tsim, nws tsis muaj txiaj ntsig kom muaj peev xwm tsim tau zoo. .

Hauv cov txheej txheem tsim khoom IC, ICs feem ntau yog npaj thiab tsim los ntawm cov tuam txhab tsim kev tshaj lij IC, xws li MediaTek, Qualcomm, Intel, thiab lwm cov tuam txhab lag luam uas paub zoo, uas tsim lawv tus kheej IC chips, muab cov kev qhia tshwj xeeb thiab kev ua haujlwm rau cov chaw tsim khoom hauv qab. xaiv los ntawm.Yog li, IC tsim yog qhov tseem ceeb tshaj plaws ntawm tag nrho cov txheej txheem tsim nti.
