Ibisobanuro

Ubwubatsi bwa TI's KeyStone itanga urubuga rushobora guhuza porogaramu zitandukanye (C66x cores, sisitemu yo kwibuka, periferique, hamwe na moteri yihuta) kandi ikoresha ibice byinshi bishya hamwe nubuhanga kugirango hongerwe uburyo bwo gutumanaho no guhuza imiyoboro ituma umutungo wa DSP utandukanye ukora neza kandi nta nkomyi.Hagati muri ubu bwubatsi ni ibice byingenzi nka Multicore Navigator itanga uburyo bwo gucunga neza amakuru hagati yibikoresho bitandukanye.TeraNet nigitambambuga kidahagarikwa gishobora kwihuta kandi kitarimo amakimbirane yimbere yimbere.Multicore isangiwe yibuka igenzura yemerera kugera kububiko busanzwe kandi bwo hanze butarinze gushushanya bivuye mubushobozi bwimyenda.Kugirango ukoreshe ingingo-ngingo, C66x yibanze ifite 4 × kugwiza (MAC) ubushobozi bwa C64x + cores.Mubyongeyeho, intangiriro ya C66x ihuza ubushobozi bwo kureremba-ingingo kandi kuri buri-mikorere yibikorwa byo kubara ni inganda ziyobora inganda 40 GMACS kuri buri kintu na 20 GFLOPS kuri buri kintu (@ 1.25 GHz ikora inshuro).Intangiriro ya C66x irashobora gukora 8 imwe yuzuye ireremba-ingingo ya MAC ibikorwa kuri buri cyiciro kandi irashobora gukora ibikorwa bibiri kandi bivanze-byuzuye kandi byujuje IEEE 754.Intangiriro ya C66x ikubiyemo amabwiriza mashya 90 (ugereranije na C64x + yibanze) agenewe kureremba-ingingo na vector imibare itunganijwe.Iterambere ritanga umusaruro munini kunoza imikorere ya DSP izwi cyane ikoreshwa mugutunganya ibimenyetso, imibare, nibikorwa byo gushaka amashusho.Intangiriro ya C66x ni code yinyuma-ihuza na TI yabanjirije iyambere C6000 ihamye- kandi ireremba-ingingo ya DSP yibanze, itanga porogaramu igendanwa kandi ikagabanya iterambere rya software kugirango porogaramu yimuke yibikoresho byihuse.C665x DSP ihuza umubare munini wububiko bwa chip.Usibye 32KB ya porogaramu ya L1 na cache yamakuru, 1024KB yibikoresho byabugenewe birashobora gushyirwaho nka RAM yashushanyije cyangwa cache.Igikoresho kandi gihuza 1024KB ya Multicore Yisangije Ububiko bushobora gukoreshwa nka L2 SRAM isangiwe na / cyangwa L3 SRAM isangiwe.Byose L2 yibuka ikubiyemo amakosa yo kumenya no gukosora amakosa.Kugirango ubone uburyo bwihuse bwo kwibuka hanze, iki gikoresho kirimo 32-biti ya DDR-3 yo kwibuka hanze (EMIF) ikora ku gipimo cya 1333 MHz kandi ifite inkunga ya ECC DRAM.
