TMS320C6748EZWTD4 IC DSP FIX/FLOAT POINT 361NFBGA

Incazelo

I-TMS320C6748 fixed- kanye nephoyinti elintantayo i-DSP iphrosesa yezinhlelo zokusebenza ezinamandla aphansi esekelwe kumongo we-C674x DSP.Le DSP inikeza amandla aphansi kakhulu kunamanye amalungu enkundla ye-TMS320C6000™ ye-DSPs.Idivayisi inika amandla abakhiqizi bezinto zoqobo (ama-OEM) kanye nabakhiqizi bomklamo woqobo (ama-ODM) ukuthi balethe ngokushesha kumadivayisi emakethe anezinhlelo zokusebenza eziqinile, izixhumanisi ezicebile zabasebenzisi, kanye nokusebenza kwephrosesa ephezulu ngokusebenzisa ukuguquguquka okukhulu kwesixazululo seprosesa esihlanganiswe ngokugcwele, esixubile.I-DSP core yedivayisi isebenzisa i-architecture esekelwe kunqolobane yezinga elingu-2.Inqolobane yohlelo yezinga 1 (L1P) iyinqolobane enemephu eqondile engu-32-KB, futhi inqolobane yedatha yeleveli 1 (L1D) iyinqolobane engu-32-KB 2-way, set-associative cache.Inqolobane yohlelo lweleveli 2 (L2P) iqukethe isikhala senkumbulo esingu-256-KB esabelwa phakathi kohlelo nesikhala sedatha.Imemori ye-L2 ingalungiswa njengememori emephu, inqolobane, noma inhlanganisela yakho kokubili.Nakuba i-DSP L2 ifinyelelwa abanye ababungazi ohlelweni, inkumbulo eyengeziwe engu-128KB ye-RAM eyabiwe iyatholakala ukuze isetshenziswe abanye ababungazi ngaphandle kokuthikameze ukusebenza kwe-DSP.Kumadivayisi anikwe amandla ukuvikeleka, i-Basic Secure Boot ye-TI ivumela abasebenzisi ukuthi bavikele ubunikazi bobunikazi bobunikazi futhi ivimbele amabhizinisi angaphandle ekuguquleni ama-algorithms athuthukiswe umsebenzisi.Ngokuqala kusukela ku-hardwarebased "root-of-trust," ukugeleza kwebhuthi okuvikelekile kuqinisekisa indawo yokuqala eyaziwayo enhle yokwenziwa kwekhodi. Ngokuzenzakalelayo, imbobo ye-JTAG ikhiyelwe phansi ukuze kuvinjelwe ukulingisa nokuhlaselwa kokususa iphutha; kodwa-ke, imbobo ye-JTAG ingaba inikwe amandla ngesikhathi senqubo yokuqalisa evikelekile phakathi nokuthuthukiswa kohlelo lokusebenza. Amamojula okuqalisa abhalwa ngekhodi ngenkathi ehlezi kumemori yangaphandle engaguquki, efana ne-flash noma i-EEPROM, futhi akhishwa ukubethela futhi agunyazwe uma alayishwa ngesikhathi sokuqalisa okuvikelekile. Ukubethela nokubhala kuvikela i-IP yamakhasimende futhi ibavumela ngokuvikelekile setha isistimu futhi uqale ukusebenza kwedivayisi ngekhodi eyaziwayo, ethenjwayo. I-Basic Secure Boot isebenzisa i-SHA-1 noma i-SHA-256, kanye ne-AES-128 ukuze kuqinisekiswe isithombe sokuqalisa. I-Basic Secure Boot isebenzisa i-AES-128 ekubetheleni isithombe sokuqalisa. Ukugeleza kwe-boot okuvikelekile kusebenzisa isikimu sokubethela sezendlalelo eziningi esingavikeli kuphela inqubo yokuqalisa kodwa futhi esinikeza amandla okuthuthukisa ngokuvikelekile ikhodi yokuqalisa nesofthiwe yohlelo lokusebenza. Ukhiye we-cipher wedivayisi othize we-128-bit, owaziwakudivayisi kuphela futhi ekhiqizwe kusetshenziswa i-NIST-800-22 eqinisekisiwe ijeneretha yenombolo engahleliwe, isetshenziselwa ukuvikela okhiye bokubethela bekhasimende.Uma kudingeka isibuyekezo, ikhasimende lisebenzisa okhiye bokubethela ukuze lidale isithombe esisha esibethelwe.
