Tshiab RISC-V processor thov kom cov ntaub ntawv kev ua haujlwm ib watt

Lub RISC-V architecture yog qhov tshiab, tab sis cov tuam txhab uas siv nws los tsim cov txheej txheem niaj hnub (CPU) yog nce tiav qhov ua tau zoo uas qee zaum piv rau cov tuam tsev qub thiab nrov (ARM, x 86, x 64, thiab lwm yam).

Micro Khawv koob, ib tus neeg ua haujlwm RISC-V, tshaj tawm Tsis ntev los no leej twg tsim lub ntiaj teb ceev tshaj 64-ntsis RISC-V processor uas outperforms Apple lub M1 nti thiab ARM Cortex-A9. Qhov CPU no yog, raws li Micro Khawv koob, lub cim ntawm lub zeem muag ntawm David Patterson, tus thawj coj ntawm pawg thawj coj ntawm lub RISC-V Foundation, rau RISC architecture.

Qhov kev qhia teeb tsa architecture tsim nyog sib tw nrog cov qauv kev lag luam xws li ARM, nws lub koob meej tau tawg nyob rau xyoo tas los, tshwj xeeb ua tsaug rau cov smartphones.

Piv txwv, ARM-based M1 processor tsis ntev los no qhia los ntawm Apple tau ua rau muaj kev cuam tshuam ntawm cov neeg txhawb zog, cov neeg tshuaj ntsuam, thiab IT kev lag luam ntawm lub lag luam loj. RISC-V yog qhov kev deb los ntawm kev ua tiav qhov kev paub txog ARM lossis lwm yam kev qhia teeb tsa cov qauv txheej txheem, tab sis cov koom haum uas ua haujlwm nws tau thov cov ntawv sau ua haujlwm.

Xws li, Khawv koob me me, California lub tuam txhab lag luam paub zoo tshaj plaws rau nws cov khoom siv Hluav Taws Xob Tsim Kho Hluav Taws Xob (EDA) tau hais tias nws tau ua haujlwm ib ntus rau qhov uas nws xav tias lub ntiaj teb ceev tshaj 64-ntsis RISC-V lub noob pob. Los ua pov thawj nws, kev lag luam cov neeg thuam tau hais tias Micro Magic cov txheej txheem tshiab muaj cov kev ua tau zoo nrog cov ntaub ntawv ntsuas rhuav.

Khawv koob me me thov kom muaj peev xwm thauj khoom, saib thiab kho tus qauv tsim ntawm ntau tshaj ib trillion ntawm transistors hauv lub sijhawm. Lub tuam txhab tau tsim nyob rau xyoo 1995, muag rau Juniper Networks rau $ 260 lab, thiab hauv 2004 nws tau los ntawm tib lub npe los ntawm cov thawj cov tsim. Cov neeg tsim tsa, Mark Santoro thiab Lee Tavrow, ua haujlwm ua ke ntawm Sun Microsystems thiab tau coj pab pawg uas tsim SPARC 300MHz microprocessor.

Raws li Andy Huang, tus kws pab tswv yim rau Micro Khawv koob thiab tus tsim kom muaj kev tsim FineSim Circuit Court sim, Santoro tseem hais qhia txog Steve Jobs ntawm Apple.

Kwv yees li ib hlis dhau los, Micro Khawv koob tau pom nws cov 64-ntsis RISC-V ntsiav rau EETimes magazineCov. Cov ntawv xov xwm tshaj tawm hais tias cov tub ntxhais mus txog 5 GHz thiab 13.000 CoreMarks ntawm 1,1 V.

Cov tub ntxhais ntsuas tau khiav ntawm ib qho Odroid SBC. Qhov no yog kauj ruam tseem ceeb, tab sis feem ntau ib qho Micro khawv koob tseem ceeb ua haujlwm ntawm 0.8V nominal los muab 11,000 CoreMarks ntawm 4.25GHz, thaum noj tsuas yog 200mW.

Micro Covc tom qab tshaj tawm tias tib cov processor tuaj yeem xa tau ntau dua 8,000 CoreMarks ntawm 3 GHz thaum noj tsuas yog 69 mW ntawm lub zog.

Ua ntej tshaj plaws, CoreMark yog dab tsi?

Nws yog lub hom phiaj ua kom yooj yim CPU cov khoom siv tau luam tawm los ntawm Embedded Microprocessor Benchmark Consortium (EMBC), tsim los ua lub platform nruab nrab thiab yooj yim los tsim thiab siv li sai tau.

CoreMark tsom rau cov haujlwm yooj yim ntawm cov kav dej ntawm CPU, suav nrog kev nyeem / sau ntawv, tus lej, thiab kev tswj haujlwm.

Qhov no tshwj xeeb zam dhau qhov feem ntau ntawm cov teebmeem ntawm cov kab ke sib txawv hauv lub cim xeeb, I / O, thiab lwm yam. EMBC yog ib pab pawg muaj npe thoob plaws hauv kev lag luam: Intel, Texas Cov Khoom Siv, ARM, Realtek thiab Nokia yog qee tus neeg tseem ceeb tshaj plaws thiab pom tau yooj yim.

Rov qab mus rau M1 nti, Huang sim piav qhia qhov tseem ceeb ntawm Micro Khawv koob ua piv rau Apple lub CPU.

"Siv lub EMBC kev ntsuas, peb tau txais 55.000 CoreMarks ib watt. M1 nti yog kwv yees qhov sib npaug ntawm 10,000 tus CoreMarks los ntawm qhov ntsuas sib tw no.

Faib cov lej ntawd los ntawm yim tus lej thiab 15 W tag nrho, thiab uas tsawg dua 100 CoreMarks ib watt. ARM cov txheej txheem ceev tshaj plaws los ntawm EMBC cov qauv yog Cortex-A9 (plaub-core core-tub ntxhais), nrog rau daim duab ntawm 22.343 CoreMarks. Faib tus lej ntawd los ntawm plaub tus lej thiab 5 W ib tus tub ntxhais, thiab koj tau txais 1112 CoreMarks ib Watt, ”nws hais.

Tom qab ntawd nws piav qhia qhov tseem ceeb ntawm 200 mW ntawm lub zog noj ntawm lub Micro Micro CPU tshiab.

"Hauv cov khoom siv roj teeb uas niaj hnub no, CoreMarks ntawm ib lub watt loj dua li ntawm CoreMarks ntawm Megahertz. Rau cov khoom siv xws li 5W, peb tuaj yeem haum 25 cores. Leej twg tuaj yeem ua 25 lub siab hauv lub lag luam txawb xov tooj? Cov neeg feem coob tau txwv rau plaub lossis yim qhov me me. Yog li rau cov tuam txhab uas xav txo qis siv roj teeb, xws li Tesla, peb tuaj yeem ua tiav qhov kev ua tau zoo uas peb xav tau, "nws hais.
