Sabon mai sarrafa RISC-V yayi ikirarin yin rikodin ta watt

Gine-ginen RISC-V sabon sabo ne, amma kamfanonin da suke amfani da shi don tsara injiniyoyi na zamani (CPU) suna ƙara samun nasara wanda a wasu lokuta yake kwatankwacin tsoffin mashahuran gine-gine (ARM, x86, x64, da sauransu).

Micro Magic, mai ba da sabis na RISC-V, ya sanar kwanan nan wanda ya tsara mai sauri 64-bit RISC-V processor ta duniya wanda yafi karfin M1 na Apple da ARM Cortex-A9. Wannan CPU shine, a cewar Micro Magic, kwatankwacin hangen nesan David Patterson, mataimakin shugaban kwamitin RISC-V Foundation, na tsarin RISC.

Wannan koyarwar saita tsarin gine-gine ya kamata yayi gasa tare da matsayin masana'antu kamar ARM, wanda shahararsa ta fashe a 'yan shekarun nan, musamman saboda wayoyin zamani.

Misali, masarrafar M1 mai tushen ARM da Apple ya gabatar kwanan nan ya haifar da daɗaɗa tsakanin masu sha'awar, manazarta, da masana'antar IT gaba ɗaya. RISC-V hanya ce mai nisa daga samun sanannen sanannen kayan aiki na ARM ko wasu tsarin koyarwar da aka tsara, amma ƙungiyoyin da ke aiki da ita suna neman yin rikodin.

Saboda haka, Micro Sihiri, wani kamfani ne na California wanda aka fi sani da kayan aikin Electronic Design Automation (EDA) Ya ce ya yi aiki na ɗan lokaci a kan abin da ya ɗauka mafi sauri 64-bit RISC-V kernel a duniya. Don tabbatar da hakan, masu sukar masana'antu sun ce sabon mai sarrafa Micro Magic yana ba da kyakkyawan aiki tare da ingantaccen rikodi.

Micro Sihiri yayi ikirarin zai iya lodawa, dubawa da canza fasalin fasalin transistors sama da tiriliyan a zahiri. An kafa kamfanin a 1995, an siyar da shi zuwa Juniper Networks akan dala miliyan 260, kuma a 2004 an samo shi a ƙarƙashin suna iri ɗaya ta waɗanda suka samo asali. Waɗanda suka kafa su, Mark Santoro da Lee Tavrow, sun yi aiki tare a Sun Microsystems kuma sun jagoranci ƙungiyar da ta haɓaka microprocessor na SPARC 300MHz.

A cewar Andy Huang, mai ba da shawara ga Micro Magic kuma mahaliccin kirkirar na'urar kwaikwayo ta FineSim, Santoro ya kuma yiwa Steve Jobs bayani a kamfanin Apple.

Kimanin wata daya ke nan, Micro Magic ya nuna kwayar RISC-V ta 64-bit ga mujallar EETimes. Daga baya mujallar ta ruwaito cewa asalin ya kai 5 GHz da 13.000 CoreMarks a 1,1 V.

Gwajin gwajin yana gudana akan Odroid SBC. Wannan mahimmin mataki ne, amma gabaɗaya ainihin Micro Magic yana aiki a 0.8V maras muhimmanci don samar da 11,000 CoreMarks a 4.25GHz, yayin cinye 200mW kawai.

Micro Magicc daga baya ya sanar cewa mai sarrafawa ɗaya zai iya sadar da CoreMarks sama da 8,000 a 3 GHz yayin cinye 69 mW kawai na makamashi.

Da farko dai, menene CoreMark?

Kayan aiki ne na daidaitaccen CPU wanda aka sanya shi da gangan wanda Embedded Microprocessor Benchmark Consortium (EMBC) ya wallafa, an tsara shi don zama tsaka tsaki a dandamali kuma mai sauƙin ginawa da amfani da shi.

CoreMark yana mai da hankali ne kawai ga ayyukan asali na bututun mai na CPU, gami da karatu / rubutu na asali, adadi, da ayyukan sarrafawa.

Wannan yana hana yawancin tasirin bambancin tsarin cikin ƙwaƙwalwar ajiya, I / O, da dai sauransu. EMBC rukuni ne da aka wakilta a cikin masana'antar: Intel, Texas Instruments, ARM, Realtek, da Nokia wasu sanannun mambobi ne sanannu.

Komawa gun M1, Huang yayi ƙoƙari ya bayyana mahimmancin aikin Micro Magic idan aka kwatanta da CPU na Apple.

“Ta amfani da ma'aunin EMBC, mun sami CoreMarks 55.000 a kowane watt. M1 ɗin M10,000 yayi daidai da XNUMX CoreMarks ta wannan maƙasudin.

Raba wannan lambar ta tsakiya takwas da jimlar 15 W, kuma wannan bai wuce 100 CoreMarks a kowace watt ba. Mai sarrafa ARM mafi sauri ta ma'aunin EMBC shine Cortex-A9 (quad-core), tare da adadi na 22.343 CoreMarks. Raba wannan lambar ta tsakiya hudu da 5 W a kowace kwakwalwa, kuma zaka samu 1112 CoreMarks ta Watt, ”inji shi.

Sannan ya bayyana mahimmancin 200 mW na amfani da wutar lantarki na sabon Micro Magic CPU.

“A cikin na’urorin da ke amfani da batir a yau, CoreMarks da watt sun fi CoreMarks girma a kan Megahertz. Don na'urar 5W ta al'ada, zamu iya dacewa da ƙwayoyin 25. Wanene zai iya sanya zukata 25 a cikin masana'antar wayar hannu? Yawancin mutane suna iyakance ga maɗaura huɗu ko takwas. Don haka ga kamfanonin da suke bukatar rage amfani da batir, kamar su Tesla, za mu iya cimma nasarar da muke bukata, ”inji shi.
