Chipset
O le chipset (Chipset) o le vaega autu o le motherboard ma e masani ona vaevaeina i Northbridge chips ma Southbridge chips e tusa ai ma la latou faʻatulagaga i luga o le motherboard.O le Northbridge chipset e tuʻuina atu le lagolago mo le ituaiga CPU ma le tele o taimi, ituaiga manatua ma le maualuga maualuga, ISA / PCI / AGP slots, faʻasaʻoga sese ECC, ma isi.O le Southbridge chip e maua ai le lagolago mo KBC (Keyboard Controller), RTC (Real Time Clock Controller), USB (Universal Serial Bus), Ultra DMA/33(66) EIDE faʻaliliuina faʻamatalaga, ma ACPI (Advanced Power Management).O le North Bridge chip o loʻo taʻitaʻia le matafaioi ma e lauiloa foi o le Host Bridge.
O le chipset e matua faigofie foi ona iloa.Ave le Intel 440BX chipset, mo se faʻataʻitaʻiga, o lona North Bridge chip o le Intel 82443BX chip, lea e masani ona tuʻu i luga o le motherboard i tafatafa o le CPU slot, ma ona o le maualuga o le vevela o le vaʻa, e faʻapipiʻi ai se masini i luga o lenei pu.O le Southbridge chip o loʻo tu latalata i le ISA ma PCI slots ma e faʻaigoaina Intel 82371EB.O isi chipsets o loʻo faʻatulagaina i le tulaga tutusa.Mo chipsets eseese, e iai foʻi eseesega i le faʻatinoga.
O chips ua avea ma mea uma, ma komepiuta, telefoni feʻaveaʻi, ma isi masini numera ua avea ma vaega taua o le ie lautele.E mafua ona o faʻamatalaga faʻaonaponei, fesoʻotaʻiga, gaosiga, ma felauaiga, e aofia ai le Initaneti, e faʻalagolago uma i le i ai o fesoʻotaʻiga tuʻufaʻatasia, ma o le matua o ICs o le a taʻitaʻia ai se oso tele i luma, e le gata i le tulaga o tekinolosi mamanu ma tulaga. o fa'alavelave i faiga semiconductor.
O se atigipusa, lea e fa'asino i le fa'ama'i silikoni o lo'o i ai le feso'ota'iga tu'ufa'atasi, o lea ua ta'ua ai le va'a, atonu e na'o le 2.5 cm sikuea le lapopoa ae o lo'o i ai le fiasefulu miliona o transistors, a'o fa'agasolo faigofie e mafai ona i ai le faitau afe o transistors e togitogia i totonu o se pu i ni nai millimita. sikuea.O le pu o le vaega pito sili ona taua o se masini faaeletonika, o loʻo faʻatinoina galuega o le komepiuta ma le teuina.
O le faiga o mamanu chip lele maualuga
O le fausiaina o se pu e mafai ona vaevaeina i ni vaega se lua: mamanu ma le gaosiga.O le faagasologa o le gaosiga o chip e pei o le fausiaina o se fale ma le Lego, faatasi ai ma wafers e fai ma faavae ona faʻapipiʻi lea i luga o faʻasologa o le gaosiga o chip e maua ai le IC chip manaʻomia, ae ui i lea, e aunoa ma se mamanu, e leai se aoga o le malosi o le gaosiga gafatia. .
I le faagasologa o le gaosiga o le IC, o ICs e tele lava ina fuafuaina ma mamanuina e kamupani faʻapolofesa IC design, e pei o MediaTek, Qualcomm, Intel, ma isi taʻutaʻua taʻutaʻua gaosi oloa, o loʻo mamanuina a latou lava IC chips, tuʻuina atu faʻamatalaga eseese ma meataalo faʻatinoga mo tagata gaosi oloa i lalo. e filifili mai ai.O le mea lea, o le IC design o le vaega pito sili lea ona taua o le faagasologa atoa o le faʻavaeina.
