Chipset

Iyo chipset (Chipset) ndiyo yakakosha chikamu chebhodhi reamai uye inowanzoganhurwa kuita machipisi eNorthbridge uye maSouthbridge machipisi zvichienderana nekurongeka kwavo pabhodhi reamai.Iyo Northbridge chipset inopa tsigiro yeCPU mhando uye main frequency, ndangariro mhando uye yakanyanya kuwanda, ISA/PCI/AGP slots, ECC kukanganisa kukanganisa, zvichingodaro.Iyo Southbridge chip inopa rutsigiro rweKBC (Keyboard Controller), RTC (Real Time Clock Controller), USB (Universal Serial Bus), Ultra DMA/33(66) EIDE nzira yekufambisa data, uye ACPI (Advanced Power Management).Iyo North Bridge chip inoita basa rinotungamira uye inozivikanwawo seHost Bridge.

Iyo chipset zvakare iri nyore kwazvo kuziva.Tora iyo Intel 440BX chipset, semuenzaniso, yayo yeNorth Bridge chip ndiyo Intel 82443BX chip, iyo inowanzowanikwa pabhodhi reamai padyo neCPU slot, uye nekuda kwekupisa kwakanyanya chizvarwa chechip, heatsink yakaiswa pane iyi chip.Iyo Southbridge chip iri padyo neISA uye PCI slots uye inonzi Intel 82371EB.Mamwe machipset akarongedzerwa mune imwechete chinzvimbo.Kune akasiyana chipsets, kune zvakare misiyano mukuita.

Chips zvave kuwanikwa kwese, nemakomputa, mbozhanhare, uye zvimwe zvigadzirwa zvedhijitari zvichiva chikamu chakakosha chesocial fabric.Izvi zvinodaro nekuti macomputer emazuva ano, kutaurirana, kugadzira, uye masisitimu ekufambisa, kusanganisira iyo Internet, zvese zvinoenderana nekuvapo kwemaseketi akabatanidzwa, uye kukura kweICs kunotungamira kune yakakura tekinoroji kusvetuka mberi, zvese maererano nehunyanzvi hwekugadzira uye maererano. yekubudirira mune semiconductor maitiro.

Chip, iyo inoreva silicon wafer ine dunhu rakasanganiswa, saka zita chip, ringangove 2.5 cm sikweya muhukuru asi ine makumi emamiriyoni ematransistors, nepo akareruka processor anogona kunge aine zviuru zvema transistors akaiswa muchip mamirimita mashoma. square.Iyo chip ndiyo inonyanya kukosha chikamu chemagetsi mudziyo, ichiita mabasa ekombuta uye kuchengetedza.

Iyo yepamusoro-inobhururuka chip dhizaini maitiro

Kusikwa kwe chip kunogona kukamurwa kuita matanho maviri: kugadzira uye kugadzira.Iyo nzira yekugadzira chip yakafanana nekuvaka imba ine Lego, ine zvimedu senheyo uyezve akaturikidzana pamusoro pematanho eiyo chip kugadzira process kuti ibudise inodiwa IC chip, zvisinei, pasina dhizaini, hazvibatsiri kuve nesimba rekugadzira rakasimba. .

Muchirongwa chekugadzirwa kweIC, maIC anonyanya kurongwa uye kugadzirwa nemakambani ekugadzira IC, akadai seMediaTek, Qualcomm, Intel, uye vamwe vagadziri vanozivikanwa zvikuru, vanogadzira yavo IC machipisi, vachipa akasiyana madhizaini uye machipisi ekuita kune vagadziri vepasi. kusarudza kubva.Naizvozvo, IC dhizaini ndiyo inonyanya kukosha chikamu chese chip kugadzirwa maitiro.
