I-chipset

I-chipset (i-Chipset) licandelo eliphambili le-motherboard kwaye lihlala lihlulwe libe yi-Northbridge chips kunye ne-Southbridge chips ngokolungiselelo lwazo kwi-motherboard.I-chipset ye-Northbridge inikeza inkxaso yohlobo lwe-CPU kunye ne-frequency ephambili, uhlobo lwememori kunye nomthamo omkhulu, i-ISA / PCI / AGP slots, ukulungiswa kwephutha le-ECC, njalo njalo.I-chip ye-Southbridge inikeza inkxaso ye-KBC (i-Keyboard Controller), i-RTC (i-Real Time Clock Controller), i-USB (i-Universal Serial Bus), i-Ultra DMA / 33 (66) indlela yokudlulisa idatha ye-EIDE, kunye ne-ACPI (Ulawulo oluPhezulu lwaMandla).I-chip yaseNorth Bridge idlala indima ephambili kwaye yaziwa ngokuba yiBridge Bridge.

I-chipset nayo ilula kakhulu ukuyichonga.Thatha i-chipset ye-Intel 440BX, umzekelo, i-chip yayo yaseNorth Bridge yi-Intel 82443BX chip, ehlala ibekwe kwi-motherboard kufuphi ne-CPU slot, kwaye ngenxa yokushisa okuphezulu kwe-chip, i-heatsink ifakwe kule chip.I-chip ye-Southbridge ikufuphi ne-ISA kunye ne-PCI slots kwaye ibizwa ngokuba yi-Intel 82371EB.Ezinye iichipsets zicwangciswe ngokwesiseko kwindawo efanayo.Kwii-chipsets ezahlukeneyo, kukho umahluko ekusebenzeni.

Iichips ziye zaxhaphaka, kunye neekhompyuter, iifowuni eziphathwayo, kunye nezinye izixhobo zedijithali ziye zaba yinxalenye yelaphu lentlalontle.Oku kungenxa yokuba i-computing yanamhlanje, unxibelelwano, ukuvelisa, kunye neenkqubo zothutho, kubandakanywa ne-Intanethi, zonke zixhomekeke kubukho beesekethe ezidibeneyo, kunye nokuvuthwa kwee-ICs kuya kukhokelela ekuqhubeni phambili kwezobuchwepheshe, zombini ngokwemigaqo yoyilo kunye nangokwemiqathango. yempumelelo kwiinkqubo ze-semiconductor.

Itshiphu, ebhekisa kwisalukhwe yesilicon equlathe isekethe edityanisiweyo, kungoko igama letshiphu, linokuba yi-2.5 cm yesikwere kuphela ngobukhulu kodwa iqulethe amashumi ezigidi zeetransistors, ngelixa iiprosesa ezilula zinokuba namawakawaka e-transistors afakwe kwitshiphu iimilimitha ezimbalwa. isikwere.Itshiphu yeyona nxalenye ibalulekileyo yesixhobo sombane, esenza imisebenzi yekhompyutha kunye nokugcinwa kwayo.

Inkqubo yoyilo lwetshiphu ephezulu ebhabhayo

Ukwenziwa kwe-chip kunokwahlulwa ibe ngamanqanaba amabini: ukuyila kunye nokuvelisa.Inkqubo yokwenziwa kwetshiphu ifana nokwakha indlu ene-Lego, eneziqwenga ezisicaba njengesiseko kwaye emva koko izaleko phezu kweengqimba zenkqubo yokwenziwa kwetshiphu ukuvelisa itshiphu ye-IC efunwayo, nangona kunjalo, ngaphandle koyilo, akunamsebenzi ukuba nesakhono esinamandla sokuvelisa. .

Kwinkqubo yokuvelisa i-IC, ii-ICs ubukhulu becala zicwangcisiwe kwaye ziyilwe ziinkampani zoyilo ze-IC, ezinje ngeMediaTek, iQualcomm, i-Intel, kunye nabanye abavelisi abakhulu abaziwayo, abayila iitshiphusi zabo ze-IC, bebonelela ngeenkcukacha ezahlukeneyo kunye neetships zokusebenza kubavelisi abasezantsi. ukukhetha kuyo.Ke ngoko, uyilo lwe-IC yeyona nto ibalulekileyo kuyo yonke inkqubo yokwenziwa kwe-chip.
