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 kwesethi yemiyalelo ye-RISC yomthombo ovulekile - inkambu yesilawuli se-V jikelele, yethule ngokusemthethweni uchungechunge lokuqala lwe-3bit 2VD olusekelwe ku-GRISD emhlabeni jikelele -v jikelele MCU - GD32VF103 imikhiqizo yochungechunge, ukuhlinzeka kusukela ku-chip kuya ekwakhiweni kohlelo lwesisekelo sekhodi, amakhithi okuthuthukisa, amathuluzi aphelele afana nokusekelwa kwamaketanga nokuqhubeka nokwakha i-RISC - V ukuthuthukiswa kwemvelo.

Njengochungechunge lokuqala lomkhiqizo womndeni we-GD32 MCU olusekelwe ku-risc-v kernel, i-MCU entsha ye-GD32VF103 risc-v iqondiswe ekuhambiseni izidingo zentuthuko evamile, futhi inikeza inketho yokusungula engabizi kakhulu ukuze i-risc-v ingene emakethe evamile ngokusebenza kahle kokucubungula kanye nezinsiza zesistimu. Izinhlobo zokupakisha ze-LQFP100, futhi igcina ukuhambisana okuphelele nemikhiqizo ekhona ekuthuthukisweni kwesofthiwe nokupakishwa kwamaphini. Lo mklamo ongakaze ubonwe futhi omusha wakha isiteshi esisheshayo phakathi kwemikhiqizo ye-GD32 Arm® kernel nemikhiqizo ye-risc-v kernel, okwenza ukukhethwa komkhiqizo kanye nokushintsha komklamo kuwo wonke ama-processor cores kuguquguquke, okwenza ukuthutha kwekhodi kube lula ekuthuthukisweni kwemboni okujulile. ukulawula, ama-electronics abathengi, i-IOT esafufusa, i-edge computing, intelligence yokwenziwa kanye nezimboni eziqondile.

I-risc-v processor core elungiselelwe ngokugcwele

I-GD32VF103 uchungechunge lwe-MCU lwamukela okusha sha olususelwe kumthombo ovulekile we-RISC wokwakha isethi yemiyalo - I-V Bumblebee processor core, iyindlela entsha emisha elula (i-GigaDevice) ibambene ngesandla, i-IP ehamba phambili ye-RISC processor IP kanye nabathengisi besixazululo - I-V core kuya kwesayensi nobuchwepheshe (i-Nuclei System yezinhlelo zokusebenza ezizimele zohlelo lokusebenza lwe-Intanethi ye-Intanethi ye-Intanethi ye-Intanethi nezinye izinto zokuthuthukisa i-Intanethi ye-Intanethi) i-RISC processor core yezentengiselwano - 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 esingu-64-bit esibanzi esikhiqiza ukuphazamiseka kwesikhathi okuchazwe yizinga le-risc-v, kodwa futhi isekela inqwaba yemithombo nokuphazamiseka kwangaphandle16. Izindlela zokubamba eziphazamisa isidleke kanye ne-vector esheshayo.Ukuphathwa kwamandla aphansi kungasekela amazinga amabili emodi yokulala.I-kernel isekela isixhumi esibonakalayo se-JTAG esijwayelekile kanye nezinga lokulungisa iphutha le-risc-v, elifanele izindawo zokunqamuka kwezingxenyekazi zekhompuyutha kanye nokulungisa amaphutha okusebenzisana.I-Bumblebee kernel iphinde isekele uchungechunge lwamathuluzi okuhlanganiswa kwe-risc-v, kanye nemvelo ye-graphical edidiyelwe ye-Linux/Windows.

I-Bumblebee kernel iklanywe nge-microarchitecture yomugqa wephayiphi osayizi oguquguqukayo enamazinga amabili, ifakwe iyunithi yokulanda imiyalelo ehlelekile kanye nesibikezelo segatsha esiguqukayo, futhi ihlanganisa izindlela ezihlukahlukene zokuklama amandla aphansi. Ingakwazi ukufeza ukusebenza kanye nokuvama kwamapayipi endabuko anamazinga amathathu ngezindleko zamapayipi anamazinga amabili, futhi ibone inzuzo yezinga le-2V yezinga lokuqala le-G3F yamandla ivumela i-G3F yezinga eliphezulu inzuzo ye-G3F yezinga le-G3F embonini yamandla. I-MCU ukuzuza ukusebenza okungu-153 DMIPS ngefrikhwensi 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%.
