Zitholele Amandla Ebhodi Le-C906 RISC-V Yabathengi
Imininingwane
I-Xuantie C906 iyiphrosesa eshibhile engu-64-bit ye-RISC-V ethuthukiswe yi-Alibaba Pingtouge Semiconductor Co., Ltd. I-Xuantie C906 isekelwe ekwakhiweni kwe-64-bit RISC-V futhi inwebise futhi yathuthukisa izakhiwo ze-RISC-V.Izithuthukisi ezinwetshiwe zihlanganisa:
1. Ukuthuthukiswa kwesethi yemiyalo: Gxila ezicini ezine zokufinyelela inkumbulo, ukusebenza kwezibalo, ukusebenza kwebhithi, kanye nokusebenza Kwenqolobane, kanye nemiyalo eyi-130 isiyonke inwetshiwe.Ngesikhathi esifanayo, ithimba lokuthuthukisa i-Xuantie processor lisekela le miyalo ezingeni lomdidiyeli.Ngaphandle kwemiyalo yokusebenza Yenqolobane, le miyalo ingahlanganiswa futhi yenziwe, okuhlanganisa ukuhlanganiswa kwe-GCC ne-LLVM.
2. Ukuthuthukiswa kwemodeli yenkumbulo: Nweba izibaluli zekhasi lememori, izici zekhasi lokusekela ezifana ne-Cacheable kanye ne-Strong order, futhi uzisekele ku-Linux kernel.
Imingcele yezakhiwo ezibalulekile ze-Xuantie C906 zifaka:
I-RV64IMA[FD]C[V] I-Architecture
Ukunwetshwa kweziyalezo ze-Pingtouge nokuthuthukiswa kobuchwepheshe
Ubuchwepheshe bokuthuthukisa imodeli yenkumbulo ye-Pingtouge
5-izigaba zephayiphi, ukukhishwa okulandelanayo kodaba olulodwa
Iyunithi yekhompuyutha ye-128-bit vector, isekela i-SIMD computing ye-FP16/FP32/INT8/INT16/INT32.
I-C906 iyisethi yemiyalo ye-RV64-bit, ukwethulwa okulandelanayo kwamazinga angu-5, 8KB-64KB L1 Ukusekelwa Kwenqolobane, akukho ukwesekwa Kwenqolobane ye-L2, ukwesekwa kokunemba okuyingxenye/okukodwa/okukabili, inhlanganisela ye-VIPT yendlela emine yenqolobane yedatha ye-L1.
Ibhodi licebile kuma-peripherals kanye ne-interfaces, okuhlanganisa i-USB, i-Ethernet, i-SPI, i-I2C, i-UART, ne-GPIO, ehlinzeka ngokuxhumeka okungenamthungo nokuxhumana ngamadivayisi angaphandle nezinzwa.Lokhu kuvumelana nezimo kuvumela abathuthukisi ukuthi bahlanganise kalula ibhodi kumasistimu akhona kanye nokuxhumana namadivayisi ahlukahlukene.Ibhodi le-C906 linezinsiza zenkumbulo ezanele, ezihlanganisa i-flash ne-RAM, ukuze kuhlangatshezwane nezinhlelo zokusebenza ezinkulu zesofthiwe namasethi edatha.Lokhu kuqinisekisa ukwenziwa kahle kwemisebenzi edinga izinsiza futhi kusekela ukuthuthukiswa kwezinhlelo zokusebenza eziyinkimbinkimbi.I-motherboard ye-C906 iklanywe inokuscalability engqondweni, ihlinzeka ngezikhala ezihlukahlukene zokunweba nokuxhumana, okufana ne-PCIe ne-DDR, yokuxhuma amanye amamojula nama-peripheral.Lokhu kuvumela onjiniyela ukuthi benze ibhodi ngokwezifiso ukuze lihlangabezane nezimfuneko zabo ezithile futhi bangeze kalula ukusebenza okwengeziwe.Ibhodi ye-C906 isekela izinhlelo zokusebenza ezidumile njenge-Linux ne-FreeRTOS, ihlinzeka ngendawo yokuthuthukiswa evamile futhi ivumela ukusetshenziswa kwamathuluzi esofthiwe ahlukahlukene nemitapo yolwazi.Lokhu kwenza inqubo yokuthuthukisa ibe lula futhi kunciphisa isikhathi sokumaketha.Ukusiza onjiniyela, ibhodi le-C906 liza nemibhalo ephelele kanye ne-SDK ezinikele equkethe ikhodi eyisibonelo, okokufundisa nemiklamo yereferensi.Lokhu kuqinisekisa ukuthi onjiniyela banezinsiza ezidingekayo ukuze baqalise ngokushesha futhi bakhe izinhlelo zabo zokusebenza ngokujula.Ngenxa yomklamo walo oqinile nezinto ezisezingeni eliphezulu, ibhodi le-C906 lithembeke kakhulu futhi lingasebenza ezindaweni ezinokhahlo.Iphinde ihlanganise izici zokuphatha amandla ezithuthukisiwe ukuze kuthuthukiswe ukusetshenziswa kwamandla nokwelula impilo yebhethri ezinhlelweni ezisebenza ngebhethri.Ukwengeza, kunomphakathi osebenzayo nowesekayo wabathuthukisi nabashisekeli abahlobene nebhodi le-C906.Umphakathi uhlinzeka ngezinsiza ezibalulekile, izinkundla zokwabelana ngolwazi, kanye nokwesekwa kwezobuchwepheshe endaweni yokuhlanganyela yokusungula izinto ezintsha nokuxazulula izinkinga.Kafushane, ibhodi le-C906 RISC-V liyinkundla yentuthuko enamandla futhi eguquguqukayo elungele ukusetshenziswa okunhlobonhlobo.Ngephrosesa yayo esebenza kahle kakhulu, izinsiza zenkumbulo ezanele, izinketho zokulinganisa, nokusekelwa okuphelele kwentuthuko, ibhodi lenza abathuthukisi bakwazi ukudala izixazululo ezintsha nezisikayo emkhakheni wezinhlelo ezishumekiwe.
