TMS320C6748EZWTD4 IC DSP FIX/FLOAT POINT 361NFBGA

Inkcazo

I-TMS320C6748 esisigxina- kunye neendawo ezidadayo ze-DSP yiprosesa yezicelo zamandla aphantsi ngokusekelwe kwi-core C674x DSP.Le DSP ibonelela ngamandla asezantsi kakhulu kunamanye amalungu eqonga le-TMS320C6000™ le-DSPs.Isixhobo senza ukuba abavelisi bezixhobo zangaphambili (i-OEMs) kunye nabavelisi be-original-design (ODMs) ukuba bazise ngokukhawuleza izixhobo zokuthengisa kunye neenkqubo zokusebenza ezinamandla, i-interfaces yomsebenzisi ocebileyo, kunye nokusebenza okuphezulu kweprosesa ngokusebenzisa ukuguquguquka okukhulu kwesisombululo esihlanganisiweyo esixutywe ngokupheleleyo.Isixhobo se-DSP esingundoqo sisebenzisa i-2-level cache-based architecture.Inqanaba le-1 yenkqubo ye-cache (L1P) yi-32-KB i-cache yemephu echanekileyo, kunye nenqanaba le-1 yedatha yedatha (L1D) yi-32-KB 2-way, i-set-associative cache.Inqanaba lesi-2 i-cache yeprogram (L2P) iqulethe i-256-KB yememori yendawo ekwabelwana ngayo phakathi kweprogram kunye nendawo yedatha.Imemori ye-L2 inokugcinwa njengememori emephu, i-cache, okanye indibaniselwano yezi zimbini.Nangona i-DSP L2 ifikeleleka ngezinye iinginginya kwinkqubo, i-128KB eyongezelelweyo ye-RAM ekwabelwana ngayo imemori iyafumaneka ukuze isetyenziswe ngabanye ababuki zindwendwe ngaphandle kokuchaphazela ukusebenza kwe-DSP.Kwizixhobo ezisebenza ngokhuseleko, i-TI's Basic Secure Boot ivumela abasebenzisi ukuba bakhusele ipropathi yobunini bengqondo kwaye ithintele amaqumrhu angaphandle ekuguquleni i-algorithms ephuhliswe ngumsebenzisi.Ngokuqala kwi "root-of-trust" esekwe kwihardware, ukuhamba kwenkqubo ekhuselekileyo kuqinisekisa indawo yokuqala eyaziwayo elungileyo yokwenziwa kwekhowudi.Ngokungagqibekanga, izibuko le JTAG litshixiwe ukunqanda ukulinganisa kunye nohlaselo lolungiso, nangona kunjalo, izibuko le JTAG Iimodyuli zesiqalo zifihliwe ngelixa uhleli kwimemori yangaphandle engaguquguqukiyo, efana neflash okanye EEPROM, kwaye zikhutshiwe kwaye zingqinwe xa zilayishiwe ngexesha lokuqalisa olukhuselekileyo. seta isixokelelwano kwaye uqalise ukusebenza kwesixhobo ngekhowudi eyaziwayo, ethembekileyo. UkuQalisa okuSiseko okuKhuselekileyo kusebenzisa nokuba yi-SHA-1 okanye i-SHA-256, kunye ne-AES-128 yoqinisekiso lomfanekiso wesiqalo. Ukuhamba ngokukhuselekileyo kwesiqalo kusebenzisa iskimu soguqulelo oluntsonkothileyo lwemaleko amaninzi engakhuseli kuphela inkqubo yokuqalisa kodwa inika isakhono sokuphucula ngokukhuselekileyo isiqalelo kunye nekhowudi yesoftware yesicelo.kuphela kwisixhobo kwaye iveliswe kusetyenziswa i-NIST-800-22 eqinisekisiweyo ye-random generator, isetyenziselwa ukukhusela izitshixo zofihlo lwabathengi.Xa uhlaziyo lufuneka, umthengi usebenzisa izitshixo ezifihliweyo ukwenza umfanekiso omtsha ofihliweyo.
