Chipset
Chipset (Chipset) ndiye chigawo chachikulu cha bolodi la amayi ndipo nthawi zambiri amagawidwa kukhala tchipisi ta Northbridge ndi tchipisi ta Southbridge malinga ndi kakonzedwe kawo pa boardboard.Chipset ya Northbridge imapereka chithandizo cha mtundu wa CPU ndi ma frequency akuluakulu, mtundu wa kukumbukira ndi mphamvu zambiri, ISA / PCI / AGP mipata, kukonza zolakwika za ECC, ndi zina zotero.Chip Southbridge imapereka chithandizo kwa KBC (Keyboard Controller), RTC (Real Time Clock Controller), USB (Universal Serial Bus), Ultra DMA/33(66) EIDE njira yotumizira deta, ndi ACPI (Advanced Power Management).Chip cha North Bridge chimakhala chotsogola komanso chimadziwikanso kuti Host Bridge.
Chipset ndiyosavuta kuzindikira.Tengani chipangizo cha Intel 440BX, mwachitsanzo, chipangizo chake cha North Bridge ndi chipangizo cha Intel 82443BX, chomwe nthawi zambiri chimakhala pa bolodi la amayi pafupi ndi CPU slot, ndipo chifukwa cha kutentha kwakukulu kwa chip, heatsink imayikidwa pa chip ichi.Chip cha Southbridge chili pafupi ndi malo a ISA ndi PCI ndipo chimatchedwa Intel 82371EB.Ma chipset enawo amakonzedwa m'malo omwewo.Kwa ma chipsets osiyanasiyana, palinso kusiyana kwa magwiridwe antchito.
Ma chips akhala ponseponse, pomwe makompyuta, mafoni am'manja, ndi zida zina za digito zakhala gawo lofunikira kwambiri pazamasewera.Izi zili choncho chifukwa makina amakono a makompyuta, kulankhulana, kupanga, ndi zoyendetsa, kuphatikizapo intaneti, zonse zimadalira kukhalapo kwa mabwalo ophatikizika, ndipo kukhwima kwa ma ICs kudzatsogolera ku chitukuko chachikulu chaumisiri, ponse pakupanga luso lamakono komanso ponena za teknoloji. Kupititsa patsogolo njira za semiconductor.
Chip, chomwe chimatanthawuza chophatikizira cha silicon chokhala ndi gawo lophatikizika, chifukwa chake dzina la chip, mwina lingakhale lalikulu masentimita 2.5 kukula kwake koma lili ndi ma transistors mamiliyoni makumi ambiri, pomwe mapurosesa osavuta amatha kukhala ndi masauzande a transistors okhazikika mu chip mamilimita angapo. lalikulu.Chip ndi gawo lofunika kwambiri la chipangizo chamagetsi, chomwe chimagwira ntchito zamakompyuta ndi kusunga.
Njira yopangira chip yowuluka kwambiri
Kupanga chip kungagawidwe m'magawo awiri: kupanga ndi kupanga.Njira yopangira chip imakhala ngati kumanga nyumba yokhala ndi Lego, yokhala ndi zopyapyala ngati maziko kenako ndikuyika pazigawo za chip kupanga kupanga chip chomwe mukufuna, komabe, popanda kapangidwe, sikungakhale kothandiza kukhala ndi luso lopanga kupanga. .
Popanga ma IC, ma IC nthawi zambiri amakonzedwa ndikupangidwa ndi akatswiri opanga ma IC, monga MediaTek, Qualcomm, Intel, ndi opanga ena odziwika bwino, omwe amapanga tchipisi tawo ta IC, kupereka mafotokozedwe osiyanasiyana ndi tchipisi tambiri kwa opanga otsika. kusankha.Chifukwa chake, kapangidwe ka IC ndiye gawo lofunikira kwambiri pakupanga chip chonse.
