Yamukela i-risc-v yentuthuko yomhlaba mega eqanjwe kabusha ye-GD32VF103 uchungechunge risc-v MCU

UZhaoyi usungule ukwethulwa kochungechunge lwe-GD32V i-risc-v kernel 32-bit general MCU imikhiqizo emisha, manje, isebenzisa ngokuqondile uchungechunge lwe-GD32V 32-bit general MCU ukwamukela izwe lokuthuthuka le-risc-v elinogqozi lokudala!

Ngo-Agasti 22, 2019, eBeijing, eChina - umphakeli ohamba phambili embonini we-semiconductor trillion lula innovation GigaDevice (ikhodi yesitoko: 603986) umemezele ukuthi embonini bayahola ekwethuleni ukwakhiwa komthombo ovulekile we-RISC - Inkambu yesilawuli esijwayelekile se-V, ngokusemthethweni. yethule eyokuqala emhlabeni ngokusekelwe ochungechungeni lwe-kernel lwe-GD32V 32-bit RISC -v jikelele MCU - GD32VF103 imikhiqizo yochungechunge, ukuhlinzeka kusukela ku-chip kuya ekwakhiweni kohlelo lwesisekelo sekhodi, amakhithi okuthuthukisa, amathuluzi aphelele njengokwesekwa kwamaketanga nokuqhubeka nokwakha i-RISC. - Ukuthuthukiswa kwemvelo.

Njengochungechunge lokuqala lomkhiqizo womndeni we-GD32 MCU olusekelwe ku-risc-v kernel, i-GD32VF103 risc-v MCU entsha iqondiswe ekuhambiseni izidingo zentuthuko, futhi inikeza inketho yokusungula engabizi kakhulu ukuze i-risc-v ingene emakethe evamile ngokucubungula okunokulinganisela. ukusebenza kahle kanye nezinsiza zesistimu.Iqoqo lokuqala lomkhiqizo omusha linikeza amamodeli angu-14, okuhlanganisa izinhlobo zokupakisha ze-QFN36, LQFP48, LQFP64 kanye ne-LQFP100, futhi igcina ukuhambisana okuphelele nemikhiqizo ekhona ekuthuthukisweni kwesofthiwe nokupakishwa kwamaphini.Lokhu kuklama okungakaze kubonwe ngaphambili kwakha isiteshi esisheshayo. phakathi kwemikhiqizo ye-GD32 Arm® kernel kanye nemikhiqizo ye-risc-v kernel, okwenza ukukhethwa komkhiqizo kanye nokushintshashintsha kwedizayini kuwo wonke ama-processor cores kube lula, okwenza ukuthutha kwekhodi kube lula futhi kufinyeze umjikelezo wokuthuthukiswa. , i-IOT esafufusa, i-edge computing, ubuhlakani bokwenziwa kanye nezimboni eziqondile.

I-risc-v processor core elungiselelwe ngokugcwele

I-GD32VF103 uchungechunge lwe-MCU yamukela okusha sha okusekelwe kumthombo ovulekile we-RISC wokwakha isethi yemiyalo - I-V Bumblebee processor core, iwuhlelo olusha olulula (i-GigaDevice) ngesandla, i-IP ehamba phambili ye-RISC processor IP kanye nabathengisi besixazululo - V core kusayensi nobuchwepheshe. (I-Nuclei System Technology) ye-inthanethi yezinto nezinye izimo zohlelo lokusebenza lwamandla aphansi kakhulu ezizimele zokuthuthukiswa okuhlanganyelwe kwe-RISC processor core - V.

I-Bumblebee kernel ISEBENZISA isakhiwo sesethi yomthombo ovulekile we-32-bit risc-v futhi isekela ukwenza ngokwezifiso imiyalelo ukuze kuthuthukiswe indlela yokubamba ephazamisayo. Akukhona nje ukuthi ifakwe isibali sikhathi sesikhathi sangempela esingamabhithi angu-64 esikhiqiza ukuphazamiseka kwesikhathi okuchazwa i-risc-v ejwayelekile, kodwa futhi isekela inqwaba yemithombo yokuphazamiseka yangaphandle, amazinga okuphazamiseka angu-16 nezinto eziza kuqala, futhi isekela ukuzalela izidleke eziphazamisayo kanye nezindlela zokusingatha ukuphazamiseka kwe-vector esheshayo.Ukuphatha amandla aphansi kungasekela amazinga amabili emodi yokulala.I-kernel isekela isixhumi esibonakalayo se-JTAG esijwayelekile kanye indinganiso yokulungisa iphutha ye-risc-v, ifanele izindawo zokunqanyulwa kwezingxenyekazi zekhompiyutha kanye nokulungisa iphutha lokusebenzisana.I-Bumblebee kernel iphinde isekele uchungechunge lwamathuluzi okuhlanganiswa okujwayelekile kwe-risc-v, kanye nendawo yokuthuthukisa edidiyelwe ye-Linux/Windows.

I-Bumblebee kernel idizayinelwe nge-microarchitecture yepayipi yosayizi oguquguqukayo enamazinga amabili, ifakwe iyunithi yokulanda imiyalelo ehlelekile kanye nesibikezelo segatsha esiguqukayo, futhi ihlanganisa izindlela zokuklama ezinamandla aphansi. -ipayipi lezinga ngezindleko zepayipi lamazinga amabili, futhi uqaphele isilinganiso sokuqala sokusebenza kahle kwamandla kanye nenzuzo yezindleko embonini.Lokhu kuvumela i-GD32VF103 MCU ukuthi ifinyelele ukusebenza kwe-153 DMIPS ngemvamisa ephezulu kakhulu.Ukuhlolwa kwe-CoreMark® kuphinde kwazuza amaphuzu angama-360 okusebenza okuhle kakhulu.Uma kuqhathaniswa nomkhiqizo we-GD32 Cortex® -m3 kernel, ukusebenza kuthuthukiswa ngo-15%, kuyilapho ukusetshenziswa kwamandla ashukumisayo kuncipha ngo-50% futhi ukusetshenziswa kwamandla okulindile kwehla ngo-25%.
