TMS320C6748EZWTD4 IC DSP FIX / INGINGO ZIKURIKIRA 361NFBGA

Ibisobanuro

TMS320C6748 itunganijwe- kandi ireremba-ingingo DSP ni progaramu yingufu nkeya zikoreshwa zishingiye kuri C674x DSP yibanze.Iyi DSP itanga imbaraga nke cyane ugereranije nabandi bagize TMS320C6000 ™ platform ya DSPs.Igikoresho gifasha ibikoresho-byumwimerere (OEMs) nabakora-bishushanyo-byumwimerere (ODMs) kuzana byihuse kubikoresho byisoko hamwe na sisitemu ikora ikomeye, interineti ikungahaye cyane, hamwe n’imikorere ihanitse binyuze mu buryo bworoshye bwo guhuza ibisubizo byuzuye, bivanze bitunganijwe.Igikoresho DSP yibanze ikoresha ibyiciro 2-cache-ishingiye kububiko.Urwego rwa 1 rwihishwa (L1P) ni 32-KB ya mape ya cache itaziguye, naho urwego 1 rwamakuru cache (L1D) ni 32-KB 2-nzira, gushiraho-gufatanya.Urwego rwa 2 cache ya progaramu (L2P) igizwe na 256-KB yibibanza bisangiwe hagati ya progaramu n'umwanya wa data.L2 yibuka irashobora gushyirwaho nkububiko bwa mape, cache, cyangwa guhuza byombi.Nubwo DSP L2 igerwaho nabandi bashitsi muri sisitemu, iyindi 128KB ya RAM isanganywe ububiko iraboneka kugirango ikoreshwe nabandi bashitsi bitagize ingaruka ku mikorere ya DSP.Kubikoresho bifasha umutekano, TI Yibanze Yumutekano Yibanze ituma abayikoresha barinda umutungo bwite wubwenge kandi ikabuza ibigo byo hanze guhindura algorithm-yatezimbere.Mugutangirira kumashanyarazi "imizi-y-ikizere,", umutekano wogutangiza umutekano utanga ahantu heza hazwi ho gutangirira kode. Mubisanzwe, icyambu cya JTAG gifunzwe kugirango wirinde kwigana no kugaba ibitero; icyakora, icyambu cya JTAG gishobora kuba bishobozwa mugihe cyogutangiza umutekano mugihe cyo gutezimbere porogaramu. Module ya boot irabitswe mugihe wicaye mububiko bwo hanze butavangura, nka flash cyangwa EEPROM, kandi burafungurwa kandi bwemejwe mugihe bipakiye mugihe cya boot boot umutekano. shiraho sisitemu hanyuma utangire gukora ibikoresho hamwe na code izwi, yizewe. Shingiro yumutekano wibanze ukoresha SHA-1 cyangwa SHA-256, na AES-128 mugutangiza amashusho ya boot. umutekano wibikoresho bitekanye ukoresha gahunda yo kugenzura ibintu byinshi ntabwo irinda inzira ya boot gusa ahubwo inatanga ubushobozi bwo kuzamura umutekano kode ya boot na progaramu ya software. Urufunguzo rwa 128-bit-igikoresho cyihariye cipher, kizwigusa kubikoresho kandi byakozwe hakoreshejwe NIST-800-22 yemejwe numubare utanga numero itanga, ikoreshwa mukurinda urufunguzo rwibanga rwabakiriya.Iyo ivugurura rikenewe, umukiriya akoresha urufunguzo rwibanga kugirango akore ishusho nshya ihishe.
