IiRenesas yenye yeenkampani ezininzi ukuba ilungu RISC-V Izizwe ngezizwe, esele inamalungu agcwele iinkampani ezibalulekileyo ezifana ne-Intel, AMD, NVIDIA, Western Digital, Infineon, kunye nende kakhulu njl. Ewe, zonke ezi nkampani zikho ngenxa yomdla ekulandeleni i-ISA, kwiitshiphusi ezizayo ezisekwe kuyo.
Kwaye oko kuye kwaba ngumzekelo olandelwe nguRenesas, ukuyila i-CPU entsha esekwe kwi I-32-bit RISC-V ISA (RV32) kwaye oko kufezekise isiganeko sembali, ukuba ngowokuqala kwezi mpawu ukuphumeza inqaku le-3.27 CoreMark / Mhz, oku kuthetha ngaphezu kokusebenza okuphawulekayo.
Yintoni iCoreMark/Mhz
CoreMark/MHz sisimethrikhi esisetyenziselwa ukulinganisa usetyenziso lweprosesa okanye undoqo weprosesa ngokwenani lemisebenzi yeCoreMark enokuyenza ngeMegahertz (MHz) yobuninzi bewotshi. I-CoreMark luphawu oluphuhliswe yi-Embedded Microprocessor Benchmark Consortium (EEMBC) kwaye isetyenziselwa ukuvavanya ukusebenza kweecores zeprosesa kwiinkqubo ezifakwe kunye nezifakwe ngaphakathi.
Ngokwenyani, iCoreMark/MHz ibonelela nge umlinganiselo ozalanayo wobuchule bokusetyenzwa kondoqo, ukuvumela uthelekiso phakathi koyilo lweprosesa eyahlukeneyo kunye noyilo. Ukuphakama kwexabiso le-CoreMark / MHz, i-core esebenzayo iya kuba ekwenzeni imisebenzi yokucubungula.
Kubalulekile ukuba uqaphele ukuba iCoreMark i ibhentshi yokwenziwa yenzelwe ukuvavanya ukusebenza kwizicelo ezithile, kwaye iziphumo zisenokungabonakali ngokupheleleyo kwizicelo zehlabathi lokwenene. Ukongeza, usetyenziso olwahlukeneyo kunye nomthwalo womsebenzi unokuchaphazela ukusebenza ngokwahlukileyo, ngoko ke kubalulekile ukuqwalasela iimethrikhi ezininzi kunye nemeko yokusetyenziswa xa uvavanya ukusebenza komprosesa.
Okokuqala ukufikelela kwi-3.27 CoreMark / MHz
Njengoko benditshilo, iRenesas ibhengeze ukuba iyile i-RISC-V CPU core, isiseko sayo sokuqala esekwe kule ISA. Yi 32-bit CPU, oko kukuthi, kunye neseti yomyalelo we-RV32. Lo ngundoqo we-CPU uyahambelana ne-Renesas 'e2 studio ye-studio edibeneyo yophuhliso (IDE) kwaye iyahambelana nezinye ii-IDE zeqela lesithathu ze-RISC-V microcontrollers, okwenza izinto zibe lula kubaphuhlisi.
Ngokutsho kweRenesas, i-CPU iphumelele ukusebenza kwe 3.27 CoreMark/MHz, ukugqwesa ulwakhiwo olufanayo lwe-RISC-V kolu didi, kunye nezinye ii-cores ezinolunye ulwakhiwo olwahlukileyo. Nangona kunjalo, sinikwe isihloko sale bhlog, sivuyiswa kakhulu kukuba yayiyi-RISC-V engundoqo, ekubeni i-ISA evulekileyo, ifumana ngokukhawuleza ukuthandwa kwishishini le-semiconductor, kwaye abathengisi abaninzi be-microcontroller baye baqulunqa umanyano lotyalo-mali oludibeneyo ukukhawulezisa. ukuphuhliswa kweemveliso zayo zeRISC-V.
Ngaphambili, iRenesas yazisa ii-CPU ezimbini eziphuhliswe ngu Inkampani yeAndes Technology Corp, njengokuba kunjalo kwimeko ye-R9A02G020, i-microcontroller elula yezicelo ezithile (i-ASSP okanye i-Application-Specific Standard Products) yokulawula imoto, kunye ne-R9A06G150, i-ASSP microcontroller ye-interfaces yezwi, zombini ngokusekelwe kwi-RISC-V ngokunjalo, kodwa ayiyilwanga yedwa kwaye yayimalunga neMCU.
Ukongeza kuloo nto, ngoku uRenesas wazisa le ntsapho I-RZ / emihlanu, intsapho ye-64-bit ye-RISC-V microprocessors ekwaziyo ukuqhuba iLinux, kunye neRH850/U2B, iNkqubo kwiChip (SoC) yeemoto. Oku kuzalisekisa uluhlu lwemveliso yenkampani esekwe kwiRISC-V.
Renesas RISC-V CPU Iinkcukacha
Ngokuphathelele Ukucaciswa kobugcisa Kule Renesas RISC-V CPU, oku kulandelayo kufuneka kugxininiswe:
- I-CPU entsha ye-Renesas esekelwe kwi-RISC-V iguquguqukayo, kwizicelo ezahlukeneyo, kwaye ayinqunyelwe njengezinye iimeko. Ngokomzekelo, inokusetyenziswa kuzo zombini ii-MCUs, ii-SoCs, ii-ASIC, ii-AASPs, njl. Ngokukodwa ijoliswe kwishishini kunye ne-embedded okanye eyakhelwe-ngaphakathi.
- Intsebenzo iphuculwe kakhulu kuyilo lwayo, yiyo loo nto ifikelela kuloo manqaku kwibenchmark. Le CPU inokuphumeza umyalelo we-RV32 njengoko benditshilo, zombini ulwandiso lweemodyuli I kunye no-E, olwenza ukuba lulungele usetyenziso lwenjongo ngokubanzi.
- Ikwanayo nezinye iimodyuli ezidibeneyo ze-RISC-V okanye izandiso, ezifana ne-M ukuphucula ukuphindaphinda kunye nokusebenza kokwahlula, ukwandiswa kwe-A ukuxhasa ukufikelela kwe-athomu kwi-concurrency kwiinkqubo ezisekelwe kwi-RTOS, i-extension C enikezela ukuhambelana nemiyalelo ecinezelweyo ye-16-bit yokugcina imemori. isithuba, kunye ne-B, ebonelela ngezakhono zokuqhatha kancinci.
- Ngakolunye uhlangothi, ukunakekelwa okukhulu kuye kwathathwa ngokufanelekileyo, kungekhona nje ukusebenza, okwenza kube yinto efanelekileyo kwizicelo zokusetyenziswa okuphantsi.
- Inkqubo yeRejista ye-Stack Monitor idibaniswe, evimbela ukugqithiswa kwememori ye-stack, ngoko ke, ngokuphepha oku kugqithisa unokuphucula ukunyaniseka kwenkqubo, engayi kuphumelela ngenxa yezi ngxaki.
- Ikwabandakanya iYunithi yokuQikelela kweSebe leDynamic, eya kuphucula ukwenziwa kwekhowudi.
- Ewe kunjalo, ibandakanya i-JTAG debugging interface, esebenzayo, epheleleyo kunye nekhawulezayo ukulungisa, ukwenza ubomi bube lula kakhulu kubaphuhlisi.
- Kwelinye icala, ibandakanya i-ITU okanye iYunithi yokuJonga uMyalelo, ukunika abaphuhlisi ulwazi olunzulu malunga nokuziphatha kwenkqubo.
I-CPU entsha ye-Renesas RISC-V nayo iyahambelana ne Renesas e2 Studio IDE kunye neentlobo ezininzi zee-IDE zomntu wesithathu ukuphuhlisa izixhobo zale ecosystem. Ukongeza, i-chip eyenziwe yavavanywa zombini ngokwemigaqo yokusebenza kunye nemisebenzi, ngoko unovavanyo lokugqibela lwemveliso. Ngokubhekiselele ekuqalisweni, kuya kusungulwa ngo-2024, kwangethuba. Ke siya kubona iimveliso ezisekwe kwezi chips, eziya kuba nomdla kakhulu, kwaye into yeRISC-V ibonakala ingenakunqandwa kwihlabathi lehardware, njengoko iLinux yayikade ikwicala lesoftware...
