ʻO ka OMAP-L138 C6000 DSP+ARM kaʻina hana hana haʻahaʻa haʻahaʻa e pili ana i kahi ARM926EJ-S a me kahi C674x DSP core.Hāʻawi kēia mea hana i ka mana haʻahaʻa haʻahaʻa ma mua o nā lālā ʻē aʻe o ka platform TMS320C6000™ o DSPs.Hāʻawi ka mea hana i nā mea hana mea hana kumu (OEM) a me nā mea hana hoʻolālā kumu (ODMs) e lawe koke i nā mea kūʻai aku me nā ʻōnaehana hana ikaika, nā mea hoʻohana waiwai nui, a me ka hana kiʻekiʻe o ka mīkini hana ma o ka hiki ke maʻalahi o ka hoʻohui piha ʻana i ka ʻōnaehana hui.Hāʻawi ka papa hana ʻelua-core o ka hāmeʻa i nā pōmaikaʻi o nā ʻenehana DSP a me nā ʻenehana hoʻonohonoho hoʻemi hoʻemi ʻia (RISC), e hoʻopili ana i kahi kumu TMS320C674x DSP kiʻekiʻe a me kahi kumu ARM926EJ-S.ʻO ka ARM926EJ-S he 32-bit RISC core processor e hana ana i nā ʻōlelo kuhikuhi 32-bit a i ʻole 16-bit a me nā kaʻina 32-, 16-, a i ʻole 8-bit ʻikepili.Hoʻohana ke kumu i ka pipelining i hiki i nā ʻāpana āpau o ka processor a me ka ʻōnaehana hoʻomanaʻo ke hana mau.Loaʻa i ka ARM9 core kahi coprocessor 15 (CP15), module pale, a me ka ʻikepili a me nā ʻāpana hoʻomanaʻo hoʻomanaʻo papahana (MMUs) me nā pale nānā ʻaoʻao.Loaʻa i ka ARM9 kumu ke aʻo ʻokoʻa 16-KB a me nā waihona ʻikepili 16-KB.ʻO nā ʻāpana ʻelua he 4-ala hui me ka virtual index virtual tag (VIVT).Loaʻa i ka ARM9 core ka 8KB o RAM (Vector Table) a me 64KB o ROM.Ke hoʻohana nei ka mīkini DSP core i kahi hoʻolālā cache-level 2.ʻO ka papa hoʻomoe papahana pae 1 (L1P) he 32-KB i hoʻopaʻa ʻia ma ka ʻaoʻao huna huna, a ʻo ka pae 1 data cache (L1D) he 32-KB 2-ala, set-associative cache.ʻO ka pae 2 polokalamu cache (L2P) he 256-KB wahi hoʻomanaʻo i hoʻokaʻawale ʻia ma waena o ka papahana a me ka ʻikepili.Hiki ke hoʻonohonoho ʻia ka hoʻomanaʻo L2 e like me ka hoʻomanaʻo palapala ʻāina, cache, a i ʻole nā ​​hui pū ʻana o nā mea ʻelua.ʻOiai hiki ke ʻike ʻia ka DSP L2 e ka ARM9 a me nā mea hoʻokipa ʻē aʻe i ka ʻōnaehana, loaʻa kahi hoʻomanaʻo hoʻomanaʻo 128KB hou o RAM no ka hoʻohana ʻana e nā pūʻali ʻē aʻe me ka ʻole e pili ana i ka hana DSP.
