Chipset
ʻO ka chipset (Chipset) ka mea nui o ka motherboard a ua māhele pinepine ʻia i nā chips Northbridge a me Southbridge chips e like me kā lākou hoʻonohonoho ʻana ma ka motherboard.Hāʻawi ka Northbridge chipset i ke kākoʻo no ke ʻano CPU a me ke alapine nui, ke ʻano hoʻomanaʻo a me ka hiki ke kiʻekiʻe, nā slot ISA / PCI / AGP, hoʻoponopono hewa ECC, a pēlā aku.Hāʻawi ka Southbridge chip i ke kākoʻo no KBC (Keyboard Controller), RTC (Real Time Clock Controller), USB (Universal Serial Bus), Ultra DMA/33(66) EIDE data transfer method, a me ACPI (Advanced Power Management).He kūlana koʻikoʻi ka North Bridge chip a ʻike ʻia hoʻi ʻo Host Bridge.
He maʻalahi hoʻi ka chipset e ʻike.E lawe i ka chipset Intel 440BX, no ka laʻana, ʻo kāna chip North Bridge ka Intel 82443BX chip, aia ma ka motherboard kokoke i ka slot CPU, a ma muli o ka hana wela nui o ka chip, ua hoʻokomo ʻia kahi heatsink ma kēia chip.Aia ka puʻupuʻu Southbridge ma kahi kokoke i nā ISA a me PCI a ua kapa ʻia ʻo Intel 82371EB.Hoʻonohonoho ʻia nā chipsets i ke kūlana like.No nā chipsets ʻokoʻa, aia kekahi ʻokoʻa i ka hana.
Ua lilo nā chips ma nā wahi a pau, me nā kamepiula, kelepona paʻalima, a me nā mea hana kikohoʻe ʻē aʻe i lilo i ʻāpana koʻikoʻi o ka lole kaiapuni.ʻO kēia no ka mea, ʻo nā ʻōnaehana kamepiula hou, kamaʻilio, hana ʻana, a me nā ʻōnaehana kaʻa, me ka Pūnaewele, ke hilinaʻi nei nā mea a pau i ka noho ʻana o nā kaapuni i hoʻohui ʻia, a ʻo ka oʻo ʻana o nā IC e alakaʻi i kahi lele ʻenehana nui i mua, ma ke ʻano o ka ʻenehana hoʻolālā a me nā huaʻōlelo. o nā holomua i nā kaʻina semiconductor.
ʻO kahi puʻupuʻu, e pili ana i ka wafer silicon i loko o ka kaapuni i hoʻohui ʻia, no laila ka inoa chip, aia paha he 2.5 knm square ka nui akā aia nā ʻumi miliona o nā transistors, aʻo nā mea hana maʻalahi he mau tausani o nā transistors i kālai ʻia i loko o kahi chip he mau millimeters. huinaha.ʻO ka chip ka mea nui loa o kahi mea uila, e lawe ana i nā hana o ka helu a me ka mālama ʻana.
ʻO ke kaʻina hana hoʻolālā chip lele lele
Hiki ke hoʻokaʻawale ʻia ka hana ʻana o kahi chip i ʻelua mau pae: hoʻolālā a me ka hana ʻana.ʻO ke kaʻina hana o ka hana chip e like me ke kūkulu ʻana i hale me Lego, me nā wafers ke kumu a laila kau ʻia ma luna o nā papa o ke kaʻina hana chip e hana ai i ka chip IC i makemake ʻia, akā naʻe, me ka ʻole o ka hoʻolālā ʻana, he mea ʻole ka loaʻa ʻana o ka mana hana ikaika. .
Ma ke kaʻina hana IC, ua hoʻolālā a hoʻolālā ʻia nā IC e nā ʻoihana hoʻolālā IC ʻoihana, e like me MediaTek, Qualcomm, Intel, a me nā mea hana nui kaulana ʻē aʻe, nāna i hoʻolālā i kā lākou mau pahu IC ponoʻī, e hāʻawi ana i nā kikoʻī like ʻole a me nā pahu hana no nā mea hana i lalo. e koho mai.No laila, ʻo ka hoʻolālā IC ka mea nui loa o ke kaʻina hana chip holoʻokoʻa.
