TMS320C6748EZWTD4 IC DSP FIX/FLOAT POINT 361NFBGA

Tsanangudzo

Iyo TMS320C6748 yakagadziriswa- uye inoyangarara-poindi DSP ndeye yakaderera-simba application processor yakavakirwa paC674x DSP musimboti.Iyi DSP inopa simba rakaderera zvakanyanya kupfuura dzimwe nhengo dzeTMS320C6000™ chikuva cheDSPs.Chishandiso chinogonesa vagadziri vezvigadzirwa zvepakutanga (OEMs) uye vagadziri vekutanga-dhizaini (ODMs) kuti vakurumidze kuunza kumusika zvishandiso zvine akasimba masisitimu anoshanda, akapfuma mushandisi interfaces, uye yakakwirira processor mashandiro kuburikidza nekunyanya kuchinjika kweyakasanganiswa yakazara, yakasanganiswa processor mhinduro.Iyo mudziyo DSP musimboti inoshandisa 2-level cache-based architecture.Iyo level 1 chirongwa cache (L1P) ndeye 32-KB yakananga mepu cache, uye nhanho 1 data cache (L1D) ndeye 32-KB 2-nzira, set-associative cache.Iyo level 2 chirongwa cache (L2P) ine 256-KB ndangariro nzvimbo inogovaniswa pakati pechirongwa nenzvimbo yedata.L2 ndangariro inogona kugadzirwa semepu memory, cache, kana musanganiswa wezviviri.Kunyangwe iyo DSP L2 ichisvikika nemamwe mauto muhurongwa, imwe 128KB ye RAM yakagovaniswa ndangariro inowanikwa kuti ishandiswe nemamwe mauto pasina kukanganisa DSP kuita.Zvemidziyo inogonesa kuchengetedza, TI's Basic Secure Boot inoita kuti vashandisi vadzivirire pfuma yehungwaru uye inodzivirira masangano ekunze kubva pakugadzirisa maalgorithms akagadzirwa nemushandisi.Nekutanga kubva kune hardware yakavakirwa "mudzi-we-kuvimba," iyo yakachengeteka bhutsu kuyerera inovimbisa inozivikanwa yakanaka yekutanga nzvimbo yekuita kodhi. Nekumisikidza, iyo JTAG chiteshi inovharirwa pasi kudzivirira emulation uye debug kurwiswa; zvisinei, iyo JTAG port inogona inogoneswa panguva yakachengeteka yebhutsu panguva yekuvandudzwa kwekushandisa seta sisitimu uye wotanga kushanda kwemudziyo uchishandisa kodhi inozivikanwa, inovimbika. Basic Secure Boot inoshandisa SHA-1 kana SHA-256, uye AES-128 yekuona mufananidzo webhoot. Kuyerera kwakachengeteka kwebhutsu kunoshandisa multilayer encryption scheme iyo isingachengetedze maitiro ebhutsu chete asiwo inopa kugona kukwidziridza zvakachengetedzeka boot uye application software code.A 128-bit mudziyo-specific cipher key, inozivikanwakumudziyo chete uye wakagadzirwa uchishandisa NIST-800-22 yakasimbiswa isina nhamba jenareta, inoshandiswa kuchengetedza makiyi encryption makiyi.Kana imwe update ichidiwa, mutengi anoshandisa encryption kiyi kugadzira mufananidzo mutsva wakavharidzirwa.
