Sharaxaada
TMS320C6748 go'an iyo barta sabaynta DSP waa processor codsiyo hooseeya oo ku salaysan C674x DSP xudunta.DSP-kan waxa uu bixiyaa awood aad uga hooseeya xubnaha kale ee TMS320C6000™ ee madal DSPs.Qalabku wuxuu awood u siinayaa soosaarayaasha qalabka asalka ah (OEMs) iyo soosaarayaasha naqshadaynta asalka ah (ODMs) inay si dhakhso ah u keenaan aaladaha suuqa oo leh nidaamyo hawlgal oo adag, is-dhexgal isticmaale oo hodan ah, iyo waxqabadka processor-ka sare iyada oo loo marayo dabacsanaanta ugu badan ee isku-dhafan oo isku-dhafan, xal processor isku dhafan.Aaladda DSP xudunta waxay isticmaashaa qaab dhismeedka kaydka ku salaysan ee 2-heer ah.Kaydinta barnaamijka heerka 1 (L1P) waa kayd khariidad toos ah oo 32-KB ah, iyo heerka 1 xogta kaydinta (L1D) waa 32-KB 2-way, khasnad-isku-xidhka.Cache barnaamijka heerka 2 (L2P) wuxuu ka kooban yahay 256-KB meel xusuusta ah oo la wadaago inta u dhaxaysa barnaamijka iyo booska xogta.Xusuusta L2 waxa loo habayn karaa sidii xusuusta khariidad, kaydinta, ama isku darka labada.Inkasta oo DSP L2 ay heli karaan martigeliyayaasha kale ee nidaamka, 128KB dheeraad ah oo RAM ah oo la wadaago ayaa diyaar u ah isticmaalka martida kale iyada oo aan saameyn ku yeelan waxqabadka DSP.Aaladaha amniga u shaqeeya, TI's Basic Secure Boot wuxuu u oggolaanayaa isticmaaleyaasha inay ilaaliyaan hantida garaadka lahaanshaha oo waxay ka ilaalisaa hay'adaha dibadda inay wax ka beddelaan algorithms-ka isticmaala- horumariyay.Adiga oo ka bilaabaya qalab ku salaysan "xidid-kalsoonida", socodka bootka ee sugan waxa uu xaqiijiyaa meel fiican oo laga bilaabo fulinta koodka Qaybaha boot-ka waxa la sir ah marka ay dhex fadhiyaan xusuusta aan isbeddelayn ee dibadda, sida flash ama EEPROM, waana la furfuraa oo la hubiyaa marka la shubo inta lagu jiro bootinta sugan. Samee nidaamka oo bilow hawlgalka aaladda kood la yaqaan oo la aamini karo.Basic Secure Boot waxay isticmaashaa midkood SHA-1 ama SHA-256, iyo AES-128 si loo xaqiijiyo sawirka boot. socodka boot ee sugani waxa uu shaqeeyaa nidaam sireed dhawr lakab ah kaas oo aan ilaalinayn habka bootinta oo kaliya balse sidoo kale bixisa awooda lagu cusboonaysiiyo boot iyo code software codsiga furaha khaaska ah ee 128-bit, oo la yaqaanKaliya aaladda oo la soo saaray iyadoo la adeegsanayo NIST-800-22 koronto-dhaliye lambar aan sugnayn, ayaa loo isticmaalaa si loo ilaaliyo furayaasha sirta macaamiisha.Marka cusboonaysiinta loo baahdo, macmiilku wuxuu isticmaalaa furayaasha sirta ah si uu u abuuro sawir cusub oo sir ah.
