Fumana amandla eBhodi ye-C906 RISC-V yabathengi
Iinkcukacha
I-Xuantie C906 yintsika ye-64-bit ye-RISC-V ye-architecture core processor ephuhliswe ngu-Alibaba Pingtouge Semiconductor Co., Ltd. I-Xuantie C906 isekwe kwi-architecture ye-64-bit ye-RISC-V kwaye yandise kwaye yaphucula i-RISC-V ye-architecture.Ukongezwa okongeziweyo kubandakanya:
1. Ukwandiswa kweseti yomyalelo: Gxininisa kwimiba emine yofikelelo kwimemori, ukusebenza kwe-arithmetic, ukusebenza kancinci, kunye nokusebenza kweCache, kwaye imiyalelo eyi-130 iyonke iye yandisiwe.Ngexesha elifanayo, iqela lophuhliso lweprosesa yeXuantie lixhasa le miyalelo kwinqanaba lomqambi.Ngaphandle kwemiyalelo yokusebenza kweCache, le miyalelo inokudityaniswa kwaye iveliswe, ukuquka i-GCC kunye nokuhlanganiswa kweLLVM.
2. Ukuphuculwa kwemodeli yememori: Yandisa iimpawu zekhasi lememori, iimpawu zekhasi lenkxaso ezifana neCacheable kunye ne-Strong order, kwaye uzixhase kwi-Linux kernel.
Iiparamitha eziphambili zoyilo lweXuantie C906 ziquka:
RV64IMA[FD]C[V] Uyilo lwezakhiwo
Ukwandiswa komyalelo wePingtouge kunye nokuphucula itekhnoloji
Itekhnoloji yokuphucula imodeli yememori yePingtouge
Umbhobho opheleleyo onamanqanaba ama-5, umcimbi omnye uphumezo olulandelelanayo
Iyunithi yekhompyutha ye-128-bit vector, ixhasa i-SIMD computing ye-FP16/FP32/INT8/INT16/INT32.
C906 i RV64-bit umyalelo iseti, 5-level sequential single launch, 8KB-64KB L1 Cache inkxaso, akukho L2 Cache inkxaso, isiqingatha / enye / kabini ngokuchanekileyo inkxaso, VIPT ezine-indlela indibanisela L1 cache data.
Ibhodi ityebile kwi-peripherals kunye ne-interfaces, kuquka i-USB, i-Ethernet, i-SPI, i-I2C, i-UART, kunye ne-GPIO, inikezela uxhulumaniso olungenamthungo kunye nonxibelelwano kunye nezixhobo zangaphandle kunye neenzwa.Oku bhetyebhetye kuvumela abaphuhlisi ukuba badibanise ngokulula ibhodi kwiinkqubo ezikhoyo kunye nojongano kunye nezixhobo ezahlukeneyo.Ibhodi ye-C906 inemithombo yememori eyaneleyo, kuquka i-flash kunye ne-RAM, ukulungiselela izicelo ezinkulu zesofthiwe kunye neeseti zedatha.Oku kuqinisekisa ukwenziwa ngokutyibilikayo kwemisebenzi yezibonelelo kwaye ixhasa uphuhliso lwezicelo ezinzima.I-motherboard ye-C906 iyilwe ngo-scalability engqondweni, ibonelela ngeendawo ezahlukeneyo zokubeka iindawo zokubeka kunye nojongano, njenge-PCIe kunye ne-DDR, yokuqhagamshela ezinye iimodyuli kunye neeperipherals.Oku kuvumela abaphuhlisi ukuba benze ibhodi ukuba ihlangabezane neemfuno zabo ezithile kwaye yongeze ngokulula imisebenzi eyongezelelweyo.Ibhodi ye-C906 ixhasa iinkqubo zokusebenza ezithandwayo ezifana ne-Linux kunye ne-FreeRTOS, ibonelela ngemekobume yophuhliso eqhelekileyo kwaye ivumela ukusetyenziswa kwezixhobo zesoftware ezahlukeneyo kunye namathala eencwadi.Oku kwenza lula inkqubo yophuhliso kwaye kunciphisa ixesha lokuthengisa.Ukunceda abaphuhlisi, ibhodi ye-C906 iza namaxwebhu abanzi kunye ne-SDK ezinikeleyo equlethe ikhowudi yomzekelo, izifundo kunye noyilo lwereferensi.Oku kuqinisekisa ukuba abaphuhlisi banezixhobo eziyimfuneko zokuqalisa ngokukhawuleza kwaye bakhe izicelo zabo nzulu.Ngombulelo kuyilo lwayo olomeleleyo kunye nezinto ezikumgangatho ophezulu, ibhodi ye-C906 ithembekile kakhulu kwaye inokusebenza kwiimeko ezinzima.Ikwadibanisa iimpawu zolawulo lwamandla akumgangatho ophezulu ukwandisa ukusetyenziswa kwamandla kunye nokwandisa ubomi bebhetri kwizicelo ezisebenza ngebhetri.Ukongeza, kukho uluntu olusebenzayo noluxhasayo lwabaphuhlisi kunye nabanomdla abanxulumene nebhodi yeC906.Uluntu lubonelela ngezixhobo ezixabisekileyo, iiforam zokwabelana ngolwazi, kunye nenkxaso yobugcisa kwimo engqongileyo yobambiswano lokusungula izinto ezintsha kunye nokusombulula iingxaki.Isishwankathelo, ibhodi ye-C906 RISC-V yiplatifomu yophuhliso enamandla kwaye eguquguqukayo efanelekileyo ngokufanelekileyo kwiintlobo ezahlukeneyo zezicelo.Ngeprosesa yayo ephezulu yokusebenza, izibonelelo zememori ezaneleyo, ukhetho lokulinganisa, kunye nenkxaso yophuhliso olubanzi, ibhodi yenza ukuba abaphuhlisi benze izisombululo ezitsha kunye nezokusika kwintsimi yeenkqubo ezidibeneyo.
