Zhaoyi adapanga zatsopano zoyambitsa GD32V mndandanda wa risc-v kernel 32-bit general MCU zatsopano, tsopano, gwiritsani ntchito mwachindunji GD32V mndandanda wa 32-bit general MCU kukumbatira dziko lachitukuko la risc-v ndi kudzoza kwaluso!
Pa Ogasiti 22, 2019, Beijing, China - omwe akutsogolera makampani opanga ma semiconductor thililiyoni mosavuta GigaDevice (code code: 603986) adalengeza kuti mumakampani atsogolere poyambitsa mapangidwe otseguka a RISC - V general micro controller field, idakhazikitsa mwalamulo mndandanda woyamba wapadziko lonse lapansi wa 32V2V RISD RISD RISD -v General MCU - GD32VF103 mndandanda wazinthu, kuti apereke kuchokera ku chip kupita ku dongosolo la ma code base, zida zachitukuko, zida zonse monga chithandizo cha unyolo ndikupitiriza kumanga RISC - V chitukuko cha chilengedwe.
Monga gulu loyamba lazogulitsa za GD32 MCU banja lozikidwa pa risc-v kernel, GD32VF103 risc-v MCU yatsopano imayang'ana pazofunikira zachitukuko, ndipo imapereka njira yotsika mtengo yopangira risc-v kuti alowe mumsika wodziwika bwino ndikuwongolera bwino komanso zida zamadongosolo. Mitundu yolongedza ya LQFP100, ndikusunga kugwirizana kwathunthu ndi zinthu zomwe zilipo pakupanga mapulogalamu ndi mapini. kuwongolera, zamagetsi zamagetsi, IOT yomwe ikubwera, makompyuta am'mphepete, luntha lochita kupanga ndi mafakitale oyimirira.
Wokometsedwa kwathunthu risc-v purosesa pachimake
GD32VF103 mndandanda wa MCU utenga zatsopano kutengera kamangidwe kotseguka kwa RISC - V Bumblebee processor core, ndiukadaulo wosavuta (GigaDevice) wotsogola, wotsogola waku China wa RISC processor IP ndi ogulitsa mayankho - V pachimake ku sayansi ndi Technology (Nuclei System ophatikizana amagetsi otsika ndi kugwiritsa ntchito intaneti yamagetsi otsika). malonda a RISC processor core - V.
Bumblebee kernel IMAGWIRITSA NTCHITO mamangidwe a 32-bit risc-v otseguka gwero la malangizo ndikuthandizira makonda a malangizo kukhathamiritsa makina osokonekera. Nesting and fast vector interrupt systems.Kuyang'anira mphamvu zochepa kungathe kuthandizira magawo awiri a njira yogona.Nkhokwe imathandizira mawonekedwe a JTAG ovomerezeka ndi ndondomeko yowonongeka ya risc-v, yoyenera kusokoneza hardware ndi kusokoneza ma interactive debugging.Bumblebee kernel imathandiziranso risc-v standard compilation toolchain, komanso Linux/Windows graphical Integrated development environment.
Bumblebee kernel idapangidwa ndi kachipangizo kakang'ono ka mapaipi amitundu iwiri, okhala ndi gawo lowongolera komanso cholozera champhamvu chanthambi, ndikuphatikiza njira zingapo zopangira mphamvu zochepa. MCU kuti ikwaniritse magwiridwe antchito a 153 DMIPS pama frequency apamwamba kwambiri. Mayeso a CoreMark® adapezanso mfundo za 360 zochita bwino kwambiri. Poyerekeza ndi GD32 Cortex® -m3 kernel product, magwiridwe antchito amawongoleredwa ndi 15%, pomwe mphamvu yogwiritsira ntchito mphamvu imachepetsedwa ndi 50% ndipo kugwiritsa ntchito mphamvu zoyimirira kumachepetsedwa ndi 25%.
Kusakaniza koyenera koyambirira kwa mankhwala
GD32VF103 mndandanda wa risc-v MCU imapereka ma frequency a 108MHz masamu, 16KB mpaka 128KB pa-chip flash memory ndi 6KB mpaka 32KB SRAM cache. GFlash ® luso lovomerezeka lachidziwitso limathandizira kernel access flash high-speed zero wait.Bumblebee kernel imaphatikizansopo nthawi imodzi yowonjezera hardware, hardware divider, ndi accelerator kwa makompyuta apamwamba ndi zovuta zowonongeka.
Chip AMAGWIRITSA NTCHITO 2.6v-3.6v magetsi, doko la I / O lingathe kupirira mlingo wa 5V. Wokhala ndi 16-bit yowonjezera timer yothandizira magawo atatu a PWM owonjezera ndi mawonekedwe ogulira holo kuti azilamulira vekitala, ilinso ndi 4 16-bit general timers, 2 16-bit controller interruptly controller DMA2. (ECLIC) imapereka zosokoneza zakunja za 68 ndipo zimatha kukhazikitsidwa ndi zinthu 16 zomwe zimakonzedweratu kuti zithandizire kuwongolera magwiridwe antchito munthawi yeniyeni.
Zotumphukira zosiyanasiyana zamapulogalamu ambiri, kuphatikiza mpaka 3 USART, 2 UART, 3 SPI, 2 I2C, 2 I2S, 2 can2.0b ndi 1 USB 2.0fs OTG, komanso chowongolera mabasi akunja (EXMC) . (1MB / s), kawiri liwiro lapitalo.Mawonekedwe a SPI amathandizanso mawaya anayi ndikuwonjezera njira zosiyanasiyana zoyendera. Zimapangitsanso kuti zikhale zosavuta kukulitsa Quad SPI NOR Flash kuti mufike mofulumira kwambiri.Mawonekedwe a USB 2.0 FSOTG omangidwa angapereke Chipangizo, HOST, OTG ndi mitundu ina.Woyang'anira mabasi akunja (EXMC) ndi osavuta kugwirizanitsa kukumbukira kunja monga NOR Flash ndi SRAM.
Chogulitsa chatsopanocho chimaphatikiza ma 2 12-bit othamanga kwambiri adcs okhala ndi sampuli mpaka 2.6M SPS, imapereka mpaka 16 njira zochulukirachulukira, zimathandizira kusefa kwa 16-bit hardware oversampler ntchito ndi ntchito yosinthika, ndipo ili ndi 2 12-bit dacs. mapulogalamu otukuka omwe ali ndi kulumikizana kosinthika komanso kolemera.
GD32VF103 mndandanda wa risc-v kernel wapadziko lonse wa 32-bit MCU mzere wazogulitsa
"Siuyi luso ndi chizindikiro cha makampani China Integrated dera ndi kutsogolera katundu wa MCU ambiri ku China," anati Hu zhenbo, CEO wa xinlai technology.At panopa, xinlai luso ali patsogolo kafukufuku ndi chitukuko mphamvu pachimake IP ndi chida unyolo wa risc-v purosesa, ndipo ali patsogolo pa r & d ndi kupititsa patsogolo mgwirizano pakati pa China. risc-v pansi, kubweretsa zopambana zatsopano ndikupanga njira yatsopano ya China General MCU mu nthawi ya AIoT, ndikugwirira ntchito limodzi ndi ogwiritsa ntchito ambiri kuti apambane.
"Risc-v dongosolo wakhala kukwera mofulumira mu dziko ndipo wakhala akukula mofulumira azimuth mu makampani semiconductor, kulamulira mafakitale, Internet wa zinthu, wanzeru terminal ndi zina ntchito minda," anati Deng yu, wamkulu wachiwiri kwa Pulezidenti wa luso ndi bwana wamkulu wa MCU malonda division.Zhaoyi luso ndi kampani yoyamba mu makampani kukhazikitsa 32-bit risccture ambiri ercology yochokera ku chitukuko cha MCU ndi-v kupitiriza mankhwala risc-v, yomwe ikwaniritsanso kufunika kwa msika wamapangidwe otseguka ndikuthandizira kusewera pamtengo wake, kotero kuti GD32 MCU 'sitolo ya dipatimenti', yomwe imalemeretsedwa ndikuwongolera nthawi zonse, ipitiliza kupereka njira zatsopano kwa ogwiritsa ntchito.

Kukula kosalekeza kwa risc-v Development ecology
Zhaoyi zatsopano zakhala zikupereka chithandizo cholemera komanso changwiro ku chilengedwe cha GD32. Ecology yachitukuko cha Risc-v, kuphatikiza ma board osiyanasiyana achitukuko ndi mapulogalamu ogwiritsira ntchito, nawonso ali okonzeka. Ogwiritsa ntchito GD32V mndandanda wazogulitsa amatha kuzindikira mosavuta lingaliro la kapangidwe kake ndi zida zatsopano zachitukuko ndi ma code code base.Zida zatsopano zachitukuko zikuphatikizapo gd32vf103v-eval full function evaluation board, gd32vf103r-start, gd32vf1033c-start ndi gd32vf103t-starte kuyambika kwa maphukusi osiyanasiyana, kuthandizira maphukusi osiyanasiyana, kuthandizira maphukusi osiyanasiyana. ndi kukonza zolakwika kwa ogwiritsa ntchito. Kuphatikiza apo, gd32vf103-bldc motor control board board, gd-link debugging mass production tool and series of GD32 risc-v terminal design solutions from partners are given.
Trilioni zosavuta kugwirizanitsa pakati pa sayansi ndi luso lamakono limaperekanso malo osakanikirana a chitukuko cha GD32V mndandanda wa MCU Nuclei Studio.IDE yatsopanoyi imachokera ku malo otseguka a Eclipse architecture ndipo imagwirizanitsa ndi GCC, OpenOCD ndi zida zogwirizana ndi risc-v. ogwirizana nawo, kuphatikizapo Huawei IoT Studio, SEGGER j-link V10 ndi Embedded Studio.Makina ogwiritsira ntchito ophatikizidwa kuphatikizapo micc / OS II, FreeRTOS, rt-thread, Huawei LiteOS, ndi zina zotero zasinthidwa mokwanira ndipo zimatha kugwirizanitsa mwachindunji ndi mtambo.Izi zonse zimachepetsa kwambiri zovuta za chitukuko.
Yambitsani chitukuko cha risc-v nthawi yomweyo
Mndandanda wa GD32V wazinthu zatsopano zonse zimakumana ndi kudalirika kwakukulu kwa mafakitale ndi kutentha, ndipo zimapereka zaka zosachepera 10 za chitsimikizo chokhazikika.Mlingo wa chitetezo cha ESD wa chip ukhoza kufika ku 5KV mumayendedwe otulutsa thupi laumunthu (HBM) ndi 2KV mumayendedwe otulutsa chipangizo (CDM), omwe ndi apamwamba kwambiri kuposa muyezo wa chitetezo chamakampani, choncho ndiyenera kugulitsa zinthu zodalirika komanso zodalirika.
