Nyowani RISC-V processor inoti rekodhi kuita pane watt

Iyo RISC-V yekuvakisa iri nyowani, asi makambani anoishandisa kugadzira mapurosesa emazuva ano (CPU) vari kuwedzera kuita basa iyo dzimwe nguva inofananidzwa neyekare uye inozivikanwa mapurani (ARM, x86, x64, nezvimwewo).

Micro Magic, anoshanda RISC-V, akazivisa Munguva pfupi yapfuura ndiani akagadzira processor inokurumidza kupfuura makumi matanhatu nenomwe-RISC-V processor iyo inopfuura Apple's M1 chip uye ARM Cortex-A9. Iyi CPU iri, zvinoenderana neMicrosoft Magic, iyo chiratidzo chechiono chaDavid Patterson, mutevedzeri wemutungamiri webhodhi reRISC-V Foundation, yeiyo RISC yekuvakisa.

Uyu kuraira kwakamisikidza dhizaini kunofanirwa kuita inokwikwidza nemaindasitiri zviyero senge ARM, ane mukurumbira wakaputika mumakore achangopfuura, kunyanya nekuda kwema smartphones.

Semuenzaniso, iyo ARM-yakavakirwa M1 processor ichangobva kuburitswa neApple yakonzera kusagadzikana pakati pevanofarira, vaongorori, uye neindasitiri yeIT mune zvese. RISC-V inzira refu kubva mukuwana mukurumbira weARM kana imwe mirayiridzo yakamisikidzwa dhizaini, asi masangano anoishandisa arikudaira kuita rekodhi.

Saizvozvo, Micro Mashiripiti, a California-based kambani inonyanya kuzivikanwa neayo Elektroniki Dhizaini Yekushandisa (EDA) maturusi yataura kuti yanga ichishanda kwechinguva pane iyo yainofunga kuti inokurumidza kupfuura 64-bit RISC-V kernel. Kuti varatidze izvi, vashoropodzi vemaindasitiri vakati iyo nyowani Micro Magic processor inopa kuita kwakanaka nerekodhi-kuputsa kushanda.

Micro Mashiripiti inoti inokwanisa kurodha, kuona uye kugadzirisa dhizaini inodarika trillion transistors munguva chaiyo. Iyo kambani yakavambwa muna 1995, yakatengeswa kuJuniper Networks yemadhora mazana maviri nemakumi masere, uye muna260 yakawanikwa pasi pezita rimwe chete nevakavamba vepakutanga. Vakavamba, Mark Santoro naLee Tavrow, vakashanda pamwechete kuSun Microsystems uye vakatungamira timu yakagadzira microprocessor yeSPARC 2004MHz.

Sekureva kwaAndy Huang, chipangamazano weMicro Magic uye musiki wekugadzirwa kweFineSim redunhu simulator, Santoro akaudzawo Steve Jobs kuApple.

Inenge mwedzi yapfuura, Micro Magic yakaratidza 64-bit RISC-V kernel kune EETimes magazini. Magazini yakazotaura kuti iyo musimboti yakasvika pa5 GHz uye 13.000 CoreMark pa1,1 V.

Iyo bvunzo yekuyedza yaive ichimhanya pane Odroid SBC. Iri idanho rakakosha, asi kazhinji kamwechete Micro Magic musimboti unoshanda pa0.8V zita kupa 11,000 CoreMark pa4.25GHz, ichidya 200mW chete.

Micro Magicc yakazozivisa kuti processor imwecheteyo inogona kuendesa pamusoro pe8,000 CoreMark pa3 GHz ichingodya chete 69 mW yesimba.

Chekutanga pane zvese, chii chinonzi CoreMark?

Icho chishandiso chakaita nemaune CPU mabenchmarking chishandiso chakaburitswa neiyo Yakaburitswa Microprocessor Benchmark Consortium (EMBC), yakagadzirirwa kuve sepuratifomu isina kwayakare uye yakapusa kuvaka nekushandisa sezvinobvira.

CoreMark inotarisa chete pamabasa ekutanga epombi yeCPU, inosanganisira kuverenga kwekutanga / kunyora, manhamba, uye kutonga mashandiro.

Izvi zvinonyatso kudzivirira mhedzisiro yemhedzisiro musiyano mundangariro, I / O, nezvimwe. EMBC iboka rinomiririrwa zvakanyanya muindasitiri: Intel, Texas Instruments, ARM, Realtek neNokia ndidzo dzimwe dzenhengo dzayo dzinozivikanwa uye dzinozivikanwa nyore.

Kudzokera kuchipiko M1, Huang akaedza kutsanangura kukosha kwekuita kweMicrosoft Magic kana ichienzaniswa neApple's CPU.

"Tichishandisa chiratidzo cheEMBC, tinowana 55.000 CoreMark patt. Iyo M1 chip ingangoenzana neiyo zviuru gumi zveCoreMark neiyo imwecheteyo bhenji.

Govanisa iyo nhamba ne masere cores uye 15 W yakazara, uye izvo zviri pasi pezana CoreMark pa watt. Iyo inomhanyisa ARM processor neEMBC zviyero ndiyo Cortex-A100 (quad-core), ine nhamba ye9 CoreMark. Govanisa iyo nhamba nemana cores uye 22.343 W pachikamu, uye iwe unowana 5 CoreMark paWatt, ”akadaro.

Iye akabva atsanangura kukosha kweiyo 200 mW yekushandisa simba kweiyo nyowani Micro Magic CPU.

“Mumidziyo yanhasi-inofambiswa nebhatiri, CoreMark pa watt yakakura zvikuru kupfuura CoreMark pa Megahertz. Kune chaiwo 5W chishandiso, isu tinokwana makumi maviri nemashanu cores. Ndiani anogona kuita moyo makumi maviri neshanu muindasitiri yenharembozha? Vazhinji vanhu vanogumira kune mana kana masere cores. Saka kumakambani anoda kudzikisa mashandisiro ebhatiri, saTesla, tinogona kuzadzikisa mashandiro atinoda, ”akadaro.
