Keeb kwm ntawm Mikroprocessor

Mar 09, 2019

Lub advent ntawm qes-nqi computers ntawm kev sib txuas ua ke tau hloov lub sijhawm niaj hnub no. General-purpose microprocessors nyob rau hauv tus kheej computers yog siv rau kev lwv, text editing, multimedia zaub, thiab kev sib txuas lus hauv Internet. Muaj ntau lub microprocessors yog ib feem ntawm lub nruab nruab nrab, muab cov kev tswj ntawm cov khoom siv ntawm cov khoom siv los ntawm cov khoom siv mus rau cov xov tooj ntawm cev thiab cov txheej txheem tsim.


Kev siv thawj zaug ntawm "microprocessor" yog los ntawm Viatron Computer Systems [11] piav qhia txog qhov kev sib xyaws ua ke uas siv hauv lawv qhov System 21 computer uas tshaj tawm rau xyoo 1968.


Thaum xyoo 1960 los, cov neeg tsim qauv siv tau los sib sau ua ke rau hauv chav ua haujlwm (CPU) ntawm lub computer mus rau ib qho kev sib txoos ntawm cov hlau-oxide semiconductor chips, hu ua microprocessor unit (MPU) chipsets. Lub tsev kawm ntawv tau tsim los ntawm Busicom ua ntej 1969, Intel pib ua cov thawj microprocessor, 4-bit Intel 4004, hauv 1971, raws li nws cov 8-ntsis microprocessor 8008 nyob rau hauv 1972. Hauv xyoo 1969, Lee Boysel, raws li b8-ntsis arithmetic logic (3800/3804) nws tsim los ntawm Fairchild, tau tsim plaub-Phase Systems Inc. AL-1, ib daim npog 8-ntsis CPU uas tau nthuav dav rau 32-npav. Xyoo 1970, Steve Geller thiab Ray Holt ntawm Garrett AiResearch tsim cov MP944 chipset los ua kom F-14A Central Air Data Computer nyob rau ntawm lub rooj hlau-hlau chips tsim los ntawm AMI.


Cov thawj microprocessors tau tshwm sim rau xyoo 1970s thiab siv cov tshuab computer, siv binary-coded decimal (BCD) ntawm 4-ntsis lo lus. Lwm yam kev siv ntawm 4-ntsis thiab 8-ntsis microprocessors, xws li terminals, tshuab luam ntawv, ntau hom automation thiab lwm yam, tom qab tsis ntev tom qab. Nqis 8-ntsis microprocessors nrog 16-ntsis chaw nyob kuj coj mus thawj cov hom phiaj-microcomputers los ntawm mid-1970s rau.


Txij li thaum xyoo 1970, qhov kev nce ntawm kev siv microprocessors tau ua raws li Moore txoj cai; qhov no Ameslikas pom zoo tias tus naj npawb ntawm cov cheebtsam uas tuaj yeem siv rau ib nti doubles txhua xyoo. Nrog rau tam sim no technology, nws yog qhov ua tau txhua txhua ob xyoo, [12] thiab vim li ntawd Moore tau hloov lub sijhawm mus rau ob xyoos.
