I-chipset

I-chipset (Chipset) iyingxenye eyinhloko yebhodi lomama futhi ngokuvamile ihlukaniswa ngama-chips ase-Northbridge nama-Southbridge chips ngokuvumelana nokuhlelwa kwawo ebhodini lomama.I-chipset yaseNorthbridge inikeza ukusekelwa kohlobo lwe-CPU kanye nemvamisa eyinhloko, uhlobo lwememori nomthamo omkhulu, izikhala ze-ISA/PCI/AGP, ukulungiswa kwephutha le-ECC, nokunye.I-Southbridge chip inikeza usekelo lwe-KBC (Isilawuli Sekhibhodi), i-RTC (Isilawuli Sewashi Lesikhathi Sangempela), i-USB (Universal Serial Bus), i-Ultra DMA/33(66) indlela yokudlulisa idatha ye-EIDE, kanye ne-ACPI (Ukuphathwa kwamandla Okuthuthukile).I-chip yaseNorth Bridge idlala indima ehamba phambili futhi yaziwa nangokuthi i-Host Bridge.

I-chipset nayo kulula kakhulu ukuyibona.Thatha i-chipset ye-Intel 440BX, isibonelo, i-chip yayo yaseNorth Bridge iyi-Intel 82443BX chip, evame ukutholakala ebhodini lomama eduze ne-CPU slot, futhi ngenxa yokushisa okuphezulu kwe-chip, i-heatsink ifakwe kule chip.I-Southbridge chip itholakala eduze kwe-ISA kanye ne-PCI slots futhi ibizwa nge-Intel 82371EB.Amanye ama-chipset ahlelwe ngokuyisisekelo endaweni efanayo.Kuma-chipsets ahlukene, kukhona futhi umehluko ekusebenzeni.

Ama-chips asegcwele yonke indawo, njengoba amakhompuyutha, omakhalekhukhwini, nezinye izinto ezisetshenziswayo zedijithali ziba yingxenye ebalulekile yokuxhumana nabantu.Lokhu kungenxa yokuthi ikhompyutha yesimanje, ukuxhumana, ukukhiqiza, nezinhlelo zokuthutha, okuhlanganisa i-inthanethi, konke kuncike ekubeni khona kwamasekethe ahlanganisiwe, futhi ukuvuthwa kwama-ICs kuzoholela ekuqhubekeleni phambili okukhulu kwezobuchwepheshe, kokubili ngokobuchwepheshe bokuklama nangokwemibandela. yempumelelo kuzinqubo ze-semiconductor.

I-chip, esho isicwecwana se-silicon esiqukethe isekethe ehlanganisiwe, yingakho igama elithi chip, mhlawumbe libe yisikwele esingu-2.5 cm kuphela ngosayizi kodwa liqukethe amashumi ezigidi zama-transistors, kuyilapho ama-processor alula angase abe nezinkulungwane zama-transistors ajutshwe ku-chip amamilimitha ambalwa. isikwele.I-chip iyingxenye ebaluleke kakhulu yensiza ye-elekthronikhi, eyenza imisebenzi yekhompyutha nokugcina.

Inqubo yokuklama amashiphu endizela phezulu

Ukwakhiwa kwe-chip kungahlukaniswa ngezigaba ezimbili: ukuklama nokukhiqiza.Inqubo yokwenziwa kwama-chip ifana nokwakha indlu ene-Lego, enezinkwa eziyisinkwa njengesisekelo bese izingqimba phezu kwezingqimba zenqubo yokukhiqiza ama-chip ukuze kukhiqizwe i-IC chip edingekayo, nokho, ngaphandle komklamo, akusizi ukuba nekhono eliqinile lokukhiqiza. .

Enqubweni yokukhiqiza ye-IC, ama-IC ahlelwa kakhulu futhi aklanywa izinkampani zokuklama ze-IC ezingochwepheshe, njenge-MediaTek, i-Qualcomm, i-Intel, nabanye abakhiqizi abakhulu abaziwayo, abaklama ama-chips abo e-IC, banikeze ukucaciswa okuhlukile kanye nama-chips okusebenza kubakhiqizi abangaphansi komfula. ongakhetha kukho.Ngakho-ke, ukwakheka kwe-IC yingxenye ebaluleke kakhulu yayo yonke inqubo yokwakheka kwe-chip.
