Iyo OMAP-L138 C6000 DSP + ARM processor ishoma-simba application processor yakavakirwa paARM926EJ-S uye C674x DSP core.Iyi processor 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 mbiri-yepakati dhizaini yedhizaini inopa mabhenefiti ezvese DSP uye yakaderedzwa yekuraira set komputa (RISC) tekinoroji, inobatanidza yakakwirira-inoshanda TMS320C674x DSP musimboti uye ARM926EJ-S musimboti.Iyo ARM926EJ-S ndeye 32-bit RISC processor core inoita 32-bit kana 16-bit mirairo uye maitiro 32-, 16-, kana 8-bit data.Iyo yakakosha inoshandisa pipelining kuitira kuti zvikamu zvese zve processor uye memory system zvigone kushanda zvichienderera.Iyo ARM9 musimboti ine coprocessor 15 (CP15), kudzivirira module, uye data uye chirongwa chendangariro manejimendi zvikamu (MMUs) ine tafura yekutarisa-padivi mabuffer.Iyo ARM9 musimboti ine yakaparadzana 16-KB kuraira uye 16-KB data cache.Ose macache ane 4-nzira inoshamwaridzana neiyo virtual index virtual tag (VIVT).Iyo ARM9 musimboti zvakare ine 8KB ye RAM (Vector Tafura) uye 64KB yeROM.Iyo mudziyo DSP musimboti inoshandisa 2-level cache-based architecture.Iyo level 1 chirongwa cache (L1P) ndeye 32- KB yakananga mepu cache, uye level 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 neArM9 uye mamwe mauto ari muhurongwa, imwe 128KB ye RAM yakagovaniswa ndangariro inowanikwa kuti ishandiswe nemamwe mauto pasina kukanganisa DSP kuita.
