Inkcazo

I-OMAP-L138 C6000 DSP + ARM iprosesa yinkqubo yokusetyenziswa kwamandla aphantsi ngokusekelwe kwi-ARM926EJ-S kunye ne-C674x DSP core.Le prosesa 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.I-design-core ye-device ye-device inikezela ngeenzuzo zombini i-DSP kunye nokunciphisa i-teknoloji ye-computer (RISC) yokufundisa, ebandakanya i-high-performance TMS320C674x DSP core kunye ne-ARM926EJ-S engundoqo.I-ARM926EJ-S yi-32-bit ye-RISC yeprosesa engundoqo eyenza i-32-bit okanye i-16-bit imiyalelo kunye neenkqubo ze-32-, 16-, okanye i-8-bit data.Ingundoqo isebenzisa ipayipi ukwenzela ukuba zonke iindawo zeprosesa kunye nenkqubo yememori zikwazi ukusebenza ngokuqhubekayo.Ingundoqo ye-ARM9 ine-coprocessor 15 (CP15), imodyuli yokukhusela, kunye nedatha kunye neeyunithi zokulawula imemori yeprogram (i-MMUs) kunye ne-table look-side buffers.Undoqo we-ARM9 unomyalelo owahlukileyo we-16-KB kunye ne-16-KB yokugcina idatha.Zombini ii-cache zi-4-way associative kunye ne-virtual index virtual tag (VIVT).Ingundoqo ye-ARM9 nayo ine-8KB ye-RAM (Itheyibhile yeVector) kunye ne-64KB ye-ROM.Isixhobo se-DSP esingundoqo sisebenzisa i-2-level cache-based architecture.I-Level 1 program cache (L1P) yi-32- KB ye-direct mapped cache, kunye nenqanaba 1 ledatha yedatha (L1D) yi-32-KB 2-way, 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 yi-ARM9 kunye neminye imikhosi kwinkqubo, i-128KB eyongezelelweyo ye-RAM ekwabelwana ngayo imemori iyafumaneka ukuze isetyenziswe ngabanye ababuki zindwendwe ngaphandle kokuchaphazela ukusebenza kwe-DSP.
