Gamuchira risc-v budiriro yenyika mega yakagadziridzwa GD32VF103 yakatevedzana risc-v MCU

Zhaoyi yakagadziridza kuvhura GD32V yakatevedzana risc-v kernel 32-bit general MCU zvigadzirwa zvitsva, ikozvino, shandisa zvakananga GD32V akatevedzana 32-bit general MCU kugashira nyika yebudiriro ye risc-v nekurudziro yekugadzira!

Musi waNyamavhuvhu 22, 2019, Beijing, China - indasitiri inotungamira mutengesi we semiconductor trillion nyore innovation GigaDevice (stock code: 603986) yakazivisa kuti muindasitiri inotungamira mukuunza yakavhurika sosi RISC yekuraira seti yekuvaka - V general micro controller munda, zviri pamutemo. yakatanga nyika yekutanga yakavakirwa pa kernel's GD32V series 32-bit RISC -v general MCU - GD32VF103 series products, kupa kubva ku chip kuenda kuchirongwa chekugadzira code base, makiti ekusimudzira, maturusi akazara akadai secheni rutsigiro uye ramba uchivaka RISC. - V kukura kwezvakatipoteredza.

Seyekutanga chigadzirwa cheGD32 MCU mhuri yakavakirwa parisc-v kernel, iyo itsva GD32VF103 risc-v MCU yakanangana nekusimudzira zvinodikanwa zvebudiriro, uye inopa inodhura-inoshanda innovation sarudzo yerisc-v yekupinda mumusika mukuru nekugadzirisa kwakaringana. kushanda zvakanaka uye zviwanikwa zvehurongwa.Batch yekutanga yechigadzirwa chitsva chinopa mhando gumi nemana, kusanganisira QFN36, LQFP48, LQFP64 uye LQFP100 mhando dzekurongedza, uye inochengetedza kuwirirana kwakakwana nezvigadzirwa zviripo mukugadzirwa kwesoftware uye kurongedza kwepini.Ichi chisati chamboitika uye chitsva chekugadzira chinovaka nzira inokurumidza. pakati peGD32 Arm® kernel zvigadzirwa uye risc-v kernel zvigadzirwa, zvichiita kuti kusarudzwa kwechigadzirwa uye dhizaini ichinjike kuchinjika processor cores, zvichiita kuti kutama kwekodhi kuve nyore uye kupfupisa kutenderera kwebudiriro. , inobuda IOT, kumucheto komputa, hungwaru hwekugadzira uye maindasitiri akatwasuka.

Yakanyatsogadziriswa risc-v processor musimboti

GD32VF103 yakatevedzana MCU inotora iyo nyowani-yakavakirwa yakavhurika sosi RISC yekuraira seti yekuvaka - V Bumblebee processor musimboti, iri mega iri nyore innovation (GigaDevice) ruoko muruoko, China inotungamira RISC processor core IP uye mhinduro vatengesi - V musimboti kusainzi neTekinoroji. (Nuclei System Tekinoroji) yeInternet yezvinhu uye mamwe ekupedzisira akaderera simba application mamiriro akazvimirira akabatana kusimudzira kweiyo yekutengesa RISC processor core - V.

Iyo Bumblebee kernel INOSHANDISA iyo 32-bit risc-v yakavhurika sosi yekuraira seti yezvivakwa uye inotsigira magadzirirwo emirayiridzo kukwenenzvera inovhiringidza mabatirwo emuchina. risc-v chiyero, asi inotsigirawo akawanda ekunze kwekuvhiringidza masosi, 16 inovhiringidza mazinga uye zvakakosha, uye inotsigira inovhiringidza nesting uye inokurumidza vector inovhiringidza mabatirwo ekugadzirisa maitiro.Low power management inogona kutsigira mazinga maviri ehope mode.Iyo kernel inotsigira JTAG interface uye risc-v debugging standard, yakakodzera for hardware breakpoints and interactive debugging.Bumblebee kernel inotsigirawo risc-v standard compilation toolchain, pamwe neLinux/Windows graphical integrated development environment.

Iyo Bumblebee kernel yakagadzirwa neaviri-level-siyana-saizi pombi microarchitecture, yakashongedzerwa yakarongeka yekuraira prefetch unit uye ine simba rebazi rekufanotaura, uye inobatanidza dzakasiyana-siyana-yakaderera-simba nzira dzekugadzira. -level pipeline pamutengo wepiipi yemazinga maviri, uye ziva yekutanga-class simba rekushandisa reshiyo uye mutengo mukana muindasitiri.Izvi zvinobvumira GD32VF103 MCU kuti iwane kuita kwe153 DMIPS pane yakanyanya huru frequency.CoreMark® bvunzo zvakare yakawana 360 mapoinzi ekuita kwakanaka.Kuenzaniswa neGD32 Cortex® -m3 kernel chigadzirwa, kushanda kunovandudzwa ne15%, nepo kushandiswa kwesimba kunoderedzwa ne50% uye kushandiswa kwemagetsi kunoderedzwa ne25%.
