TMS320C6748EZWTD4 IC DSP FIX/FLOAT POINT 361NFBGA

Kev piav qhia

Lub TMS320C6748 tsau- thiab ntab-taw tes DSP yog lub tshuab hluav taws xob qis qis raws li C674x DSP core.Qhov DSP no muab lub zog qis dua li lwm tus tswv cuab ntawm TMS320C6000 ™ platform ntawm DSPs.Cov cuab yeej ua rau cov tuam txhab tsim khoom qub (OEMs) thiab cov tuam txhab tsim qauv qub (ODMs) kom sai sai coj mus rau cov khoom lag luam nrog cov kev ua haujlwm zoo, cov neeg siv nplua nuj interfaces, thiab kev ua haujlwm siab ntawm cov txheej txheem los ntawm qhov siab tshaj plaws ntawm kev sib xyaw ua ke, cov txheej txheem sib xyaw ua ke.Cov cuab yeej DSP core siv 2-theem cache-based architecture.Qib 1 program cache (L1P) yog 32-KB ncaj qha mapped cache, thiab qib 1 cov ntaub ntawv cache (L1D) yog 32-KB 2-txoj kev, teeb tsa-kev koom ua ke cache.Qib 2 qhov kev pab cuam cache (L2P) muaj 256-KB qhov chaw nco uas tau sib koom ntawm qhov program thiab cov ntaub ntawv chaw.L2 lub cim xeeb tuaj yeem teeb tsa raws li mapped nco, cache, lossis kev sib txuas ntawm ob.Txawm hais tias DSP L2 tuaj yeem siv tau los ntawm lwm tus tswv hauv lub kaw lus, ntxiv 128KB ntawm RAM sib koom nco muaj rau siv los ntawm lwm tus tswv yam tsis cuam tshuam rau DSP kev ua haujlwm.Rau cov cuab yeej siv kev ruaj ntseg, TI's Basic Secure Boot tso cai rau cov neeg siv tiv thaiv cov tswv cuab kev txawj ntse thiab tiv thaiv cov chaw sab nraud los ntawm kev hloov kho cov neeg siv tsim cov algorithms.Los ntawm kev pib los ntawm kev kho vajtse raws li "hauv paus-ntawm-kev ntseeg," kev ruaj ntseg khau raj ua kom paub qhov pib zoo rau kev ua lej. Cov txheej txheem khau raj tau encrypted thaum zaum hauv lub cim xeeb sab nraud, xws li flash lossis EEPROM, thiab decrypted thiab authenticated thaum loaded thaum muaj kev ruaj ntseg khau raj. teeb tsa lub kaw lus thiab pib cov cuab yeej ua haujlwm nrog cov lej paub, ntseeg siab. Basic Secure Boot siv SHA-1 lossis SHA-256, thiab AES-128 rau khau raj duab validation. Basic Secure Boot kuj siv AES-128 rau khau raj duab encryption. ruaj ntseg khau raj khiav ntiav ib tug multilayer encryption scheme uas tsis tsuas yog tiv thaiv cov txheej txheem khau raj tab sis kuj muaj peev xwm los txhim kho khau raj thiab daim ntawv thov software code.tsuas yog rau lub cuab yeej thiab tsim siv NIST-800-22 ntawv pov thawj random tooj generator, yog siv los tiv thaiv cov neeg siv khoom encryption yuam sij.Thaum xav tau kev hloov tshiab, tus neeg siv khoom siv tus yuam sij encryption los tsim cov duab encrypted tshiab.
