Whakaahuatanga
Ko te OMAP-L138 C6000 DSP+ARM he tukatuka tono mana iti i runga i te ARM926EJ-S me te C674x DSP matua.He iti ake te mana o tenei tukatuka i era atu mema o te papaaho TMS320C6000™ o DSP.Ma te taputapu ka taea e nga kaihanga taputapu taketake (OEM) me nga kaihanga hoahoa taketake (ODMs) ki te kawe tere ki te maakete nga taputapu me nga punaha whakahaere pakari, nga atanga kaiwhakamahi whai rawa, me te mahinga tukatuka teitei na roto i te tino ngawari o te otinga tukatuka whakauru katoa.Ko te hoahoanga rua-matua o te taputapu e whakarato ana i nga painga o te DSP me te whakaiti i nga hangarau huinga tohutohu rorohiko (RISC), e whakauru ana i te TMS320C674x DSP matua me te ARM926EJ-S matua.Ko te ARM926EJ-S he 32-bit RISC pūtukatuka matua e mahi 32-bit ranei 16-bit tohutohu me te tukatuka 32-, 16-, 8-bit ranei raraunga.Ka whakamahia e te matua te pipelining kia taea ai e nga waahanga katoa o te tukatuka me te punaha mahara te mahi tonu.Ko te matua ARM9 he kaikohikohikohiko 15 (CP15), kōwae whakamarumaru, me nga raraunga me nga waeine whakahaere mahara o te hotaka (MMU) me nga parepare titiro-taha tepu.Ko te ARM9 matua he tohutohu 16-KB motuhake me nga keteroki raraunga 16-KB.Ko nga keteroki e rua he hononga 4-ara me te tohu tohu mariko mariko (VIVT).Ko te ARM9 matua he 8KB o RAM (Ripanga Vector) me te 64KB o ROM.Ko te taputapu DSP matua e whakamahi ana i te hoahoanga-a-keteroki taumata-2.Ko te keteroki papatono taumata 1 (L1P) he 32- KB keteroki mapi tika, a ko te keteroki raraunga taumata 1 (L1D) he 32-KB 2-ara, huinga-hononga keteroki.Kei roto i te keteroki papatono taumata 2 (L2P) he mokowā mahara 256-KB e tiritiria ana i waenga i te papatono me te mokowā raraunga.Ka taea te whirihora i te mahara L2 hei mahara mahere, keteroki, he huinga ranei o nga mea e rua.Ahakoa ko te DSP L2 ka taea e te ARM9 me etahi atu kaihautu i roto i te punaha, he taapiri 128KB o te mahara tiritahi RAM e waatea ana hei whakamahi ma etahi atu kaihautu me te kore e pa ki te mahi DSP.
