Samalani, ARM? Ma cores atsopano a 64-bit Synopsy ARC adzagwira ntchito katatu

Ndi anthu ochepa omwe amadziwa kuti zomangamanga za ARC ndi imodzi mwazomangamanga zodziwika bwino pamodzi ndi ARM, MIPS ndi x86. Zopangidwa m'ma 1980s, zomangamanga za ARC zimagwiritsidwa ntchito muzowongolera zazing'ono zingapo pamitundu yambiri yaukadaulo wapamwamba, ndipo pafupifupi chaka chilichonse. 1,5 biliyoni zipangizo.

Posachedwapa, Synopsys Corporation yalengeza mbadwo watsopano wa 32- ndi 64-bit ARC processor cores, yomwe imalonjeza kuti idzachita katatu poyerekeza ndi oyambirira awo, ndipo idzalolanso kumanga machitidwe-pa-chip ndi 12 cores. Chifukwa chake, ma cores atsopano adzalola Synopsys kupikisana ndi ARM m'malo angapo atsopano.

"Mapulogalamu ophatikizidwa monga olamulira a SSD kapena ma network akuchulukirachulukira, omwe amafunikira kupindula kwakukulu kwa magwiridwe antchito ndi mphamvu zochepa ndi kukula," atero a John Koeter, wachiwiri kwa purezidenti wamkulu wamalonda ndi nzeru zamaluso ku Synopsys. "Ndikutulutsidwa kwa kamangidwe katsopano ka ARCv3 ndi ARC HS5x ndi HS6x cores, omanga azitha kukwaniritsa zomwe zikuchulukirachulukira za ma SoC awo lero komanso mtsogolo."

Mabanja atsopano a Synopsys DesignWare ARC amaphatikiza ma 32-bit cores HS56/HS57D/HS58 ndi 64-bit maso HS66/HS68. Mapurosesa omwe angolengezedwa kumene amayang'ana ntchito zosiyanasiyana monga olamulira a solid-state drive (SSD), owongolera ma netiweki, oyendetsa magalimoto, ma infotainment system yamagalimoto ndi ena ambiri. Poganizira za kukula kwa RAM, 64-bit ARC HD6x ikulolani kuti mupange machitidwe okhala ndi 4,5 PB ya DRAM, pamene zipangizo zochokera ku ARC HD5x ziyenera kudzichepetsera ku mavoliyumu ang'onoang'ono. Komabe, kuchuluka kwenikweni kwa RAM yothandizidwa ndi njira yogwiritsira ntchito yomwe ikugwiritsidwa ntchito, ndipo zabwino zowonekera za 64-bit CPUs zidzayendetsedwa ndi payipi yotakata komanso fayilo yayikulu yolembetsa.

Ponena za mapangidwe a DesignWare ARC HS5x ndi DesignWare ARC HS6x, amathandizira dongosolo la malangizo la ARCv3, lomwe limatha kukulitsidwa ndi malangizo a APEX (ARC processor EXtensions) ngati ena mwa makasitomala akufunika china chake. Kuphatikiza apo, ARC HS57D ili ndi purosesa ya digito ya ARCv3DSP yothandizidwa ndi malamulo 150. Ma cores atsopanowa ali ndi kuzama kwa mapaipi a magawo 10, amatha kupereka malangizo awiri pa wotchi iliyonse, komanso ali ndi gawo loyandama la 128-bit. Nthawi yomweyo, mitundu yapamwamba kwambiri ya ma maso imathandizira posungira yachiwiri (L2) mpaka 16 MB kukula.

Ponena za magwiridwe antchito, Synopsys imati 3 DMIPS pa MHz pakuwerengera kwathunthu, komanso 5,1 CoreMark pa MHz, yomwe ndiyabwino kwambiri kwa tinthu tating'ono tomwe timagwiritsa ntchito mphamvu zochepa. Chifukwa chake, 3 DMIPS pa MHz ndiyokwera kuposa ya mapurosesa amphamvu kwambiri Kotekisi-A55, pomwe 5,1 CoreMark pa MHz ndiyokwera kuposa iliyonse ARM purosesa kwa microcontrollers.

Chimodzi mwazinthu zazikulu za banja latsopano la DesignWare ARC HS5x ndi DesignWare ARC HS6x ndikutha kupanga system-on-chip (SoC) yokhala ndi 12 general processor cores ndi 16 ma accelerator apadera. Chilichonse chapakati / chothamangitsira mu purosesa yotere chimayenda pa liwiro la wotchi yake ndipo chimagwiritsa ntchito makina ake amagetsi kuti apititse patsogolo mphamvu zamagetsi. Pamodzi ndi ma cores atsopano, Synopsys imaperekanso kulumikizana kogwirizana kwa cache pa-chip ndi kusamutsa kwa data kwa 800 GB/s.

SoC yamtunduwu yochokera pamapangidwe a ARC sizodziwika kwambiri masiku ano, koma poganizira mapurosesa olonjeza a makina oyendetsa ma autopilot, kusungidwa kwa data, kuwongolera kwa data, ma cores ambiri ndi mitundu yosiyanasiyana ya ma accelerator abwera mwachangu. Izi zidzathandiza Synopsys kupikisana ndi ma ARM cores kuti apeze malo mu SoC pazogwiritsa ntchito izi, zomwe sizinachitikepo. Chifukwa chake, wopanga SSD Starblaze wayamba kale chidwi ndi DesignWare ARC HS5x ndi DesignWare ARC HS6x cores.

"Madivelopa ophatikizidwa ochita bwino nthawi zonse amakumana ndi zovuta zatsopano kuti akwaniritse magwiridwe antchito ambiri okhala ndi kukumbukira kwakukulu ndi mphamvu komanso kukula," atero a Bruce Cheng, wasayansi wamkulu ku Starblaze. "Kuthekera kosiyanasiyana kwa mapurosesa atsopano a Synopsys a 32-bit ARC HS5x ndi 64-bit HS6x kudzatithandiza kukwaniritsa mphamvu zatsopano zomwe sizikuperekedwa ndi mapurosesa ena omwe ali pamsika."

Synopsys iyamba kupereka ma ARC cores HS56, HS57D, HS58, HS66, HS68, komanso mitundu yawo yamitundu yambiri HS56MP, HS57DMP, HS58MP, HS66MP, HS68MP, kuyambira kotala lachitatu la 2020. Kuphatikiza apo, kampaniyo ipereka ARC MetaWare Development Toolkit popanga tchipisi totengera ma cores, komanso simulator ndi verifier kuti ayang'ane magwiridwe antchito a SoC asanakhazikitsidwe mu silicon. Ponena za chithandizo chochokera ku machitidwe opangira opaleshoni, ma kernels atsopano adzakhala ogwirizana ndi magawo angapo a Linux, Zephyr, komanso mitundu yosiyanasiyana ya machitidwe ogwiritsira ntchito eni ake.
