Cov Kws Nruj Xyooj ntawm RisC

Mar 09, 2019

Nyob rau hauv nruab nrab xyoo 1980s txog rau xyoo 1990, qoob loo tshiab ntawm kev ua kom siv computer tsawg (RISC) microprocessor tau tshwm sim, cuam tshuam los ntawm RISC-xws li CPU cov qauv tsim xws li IBM 801 thiab lwm tus. RISC microprocessors tau pib siv cov cav hlau tshwj xeeb thiab Unix cov chaw ua haujlwm, tab sis tom qab ntawd tau txais kev txaus siab rau lwm txoj haujlwm.


Thawj kev lag luam RISC microprocessor tsim tau tawm xyoo 1984, los ntawm MIPS Computer Systems, lub 32-ntsis R2000 (lub R1000 tsis tso tawm). Nyob rau hauv 1986, HP tau tso tawm thawj qhov system nrog PA-RISC CPU. Xyoo 1987, nyob rau hauv lub non-Unix Acorn computers '32-ntsis, ces cache-tsawg, ARM2-raws li Acorn Archimedes ua thawj kev lag luam zoo siv ARM architecture, tom qab ntawd hu ua Acorn RISC Machine (ARM); thawj silicon ARM1 hauv 1985. Lub R3000 tau tsim cov qauv zoo tiag tiag, thiab R4000 nkag tau rau lub ntiaj teb thawj muag muaj muag 64-ntsis RISC microprocessor. Cov haujlwm sib tw yuav ua rau IBM Power thiab Sun SPARC architectures. Tsis ntev tom ntej txhua tus neeg muag khoom tau tso tawm RISC tsim, nrog rau AT & T CRISP, AMD 29000, Intel i860 thiab Intel i960, Motorola 88000, DEC Alpha.


Nyob rau xyoo 1990, tsuas yog ob lub qauv ntawm RISC tsuas muaj ob lub ntsiab lus tsim rau cov ntawv thov kev pabcuam (non-embedded applications): SPARC thiab Fais fab tuag, tabsis ARM tau dhau los ua ib qho tseemceeb, nyob rau xyoo 2010s, nws los ua tus qauv RISC thib peb xam ntu.
