Chipset
Chipset (Chipset) shine babban bangaren motherboard kuma yawanci ana raba shi zuwa Northbridge chips da Southbridge chips bisa tsarinsu akan motherboard.Chipset na Northbridge yana ba da tallafi don nau'in CPU da babban mitar, nau'in ƙwaƙwalwa da matsakaicin iya aiki, ISA/PCI/AGP ramummuka, gyara kuskuren ECC, da sauransu.Guntu na Southbridge yana ba da tallafi ga KBC (Mai sarrafa Maɓalli), RTC (Mai Kula da Agogon Lokaci na Gaskiya), USB (Bas ɗin Serial na Duniya), Ultra DMA/33(66) Hanyar canja wurin bayanai na EIDE, da ACPI (Babban Gudanar da Wuta).Guntuwar Gadar Arewa tana taka rawar jagoranci kuma ana kuma san ta da Gadar Mai watsa shiri.
Chipset shima yana da sauƙin ganewa.Dauki Intel 440BX chipset, alal misali, guntu na North Bridge shine guntu na Intel 82443BX, wanda yawanci yana kan motherboard kusa da ramin CPU, kuma saboda tsananin zafi na guntu, ana sanya heatsink akan wannan guntu.Guntuwar Southbridge tana kusa da ramukan ISA da PCI kuma ana kiranta Intel 82371EB.Sauran kwakwalwan kwamfuta an shirya su a wuri guda.Ga chipsets daban-daban, akwai kuma bambance-bambancen aiki.
Chips sun zama a ko'ina, tare da kwamfutoci, wayoyin hannu, da sauran na'urori na dijital sun zama wani ɓangare na tsarin zamantakewa.Wannan shi ne saboda tsarin na'ura mai kwakwalwa, sadarwa, masana'antu, da sufuri na zamani, ciki har da Intanet, duk sun dogara ne akan wanzuwar haɗin gwiwar da'irori, kuma balagaggen ICs zai haifar da babban ci gaba na fasaha, ta fuskar fasahar ƙira da ma'auni. na ci gaba a cikin ayyukan semiconductor.
Guntu, wanda ke nufin wafer silicon ɗin da ke ɗauke da haɗaɗɗun da'ira, saboda haka guntun sunan, ƙila ya zama murabba'in 2.5 cm kawai amma ya ƙunshi dubun dubatar transistor, yayin da mafi sauƙi na'urori na iya samun dubban transistor a cikin guntu 'yan millimita kaɗan. murabba'i.Guntu ita ce mafi mahimmancin ɓangaren na'urar lantarki, mai gudanar da ayyukan kwamfuta da ajiya.
Tsarin ƙirar guntu mai tashi sama
Ƙirƙirar guntu za a iya raba zuwa matakai biyu: ƙira da ƙira.Tsarin kera guntu yana kama da gina gida tare da Lego, tare da wafers azaman tushe sannan kuma yadudduka kan tsarin ƙirar guntu don samar da guntuwar IC da ake so, duk da haka, ba tare da ƙira ba, ba shi da amfani don samun ƙarfin masana'anta mai ƙarfi. .
A cikin tsarin samar da IC, ICs galibi ana tsara su ne da ƙwararrun kamfanoni na ƙirar IC, kamar MediaTek, Qualcomm, Intel, da sauran sanannun manyan masana'antun, waɗanda ke tsara nasu guntun IC, suna ba da ƙayyadaddun ƙayyadaddun bayanai da kwakwalwan kwamfuta na wasan kwaikwayo don masana'antun ƙasa. zabi daga.Don haka, ƙirar IC ita ce mafi mahimmancin ɓangaren gabaɗayan tsarin samar da guntu.
