Purosesa ya OMAP-L138 C6000 DSP + ARM ndi purosesa yamphamvu yotsika yotengera ARM926EJ-S ndi C674x DSP pachimake.Purosesa iyi imapereka mphamvu zotsika kwambiri kuposa mamembala ena a TMS320C6000™ nsanja ya DSPs.Chipangizochi chimathandizira opanga zida zoyambira (OEMs) ndi opanga mapangidwe oyambira (ODM) kuti abweretse mwachangu zida zamsika zokhala ndi machitidwe olimba ogwiritsira ntchito, mawonekedwe ogwiritsira ntchito olemera, komanso magwiridwe antchito apamwamba kudzera pakusinthasintha kwakukulu kwa njira yophatikizira yosakanikirana, yosakanikirana.Mapangidwe apawiri a chipangizochi amapereka mapindu a DSP komanso umisiri wocheperako wamakompyuta (RISC), kuphatikiza maziko apamwamba a TMS320C674x DSP ndi maziko a ARM926EJ-S.ARM926EJ-S ndi purosesa ya 32-bit RISC yomwe imapanga malangizo a 32-bit kapena 16-bit ndi ndondomeko 32-, 16-, kapena 8-bit data.Pakatikati imagwiritsa ntchito mapaipi kuti magawo onse a purosesa ndi kukumbukira kukumbukira azigwira ntchito mosalekeza.Pakatikati ya ARM9 ili ndi coprocessor 15 (CP15), gawo lachitetezo, ndi magawo owongolera ma data ndi mapulogalamu (MMUs) okhala ndi ma buffer owonera patebulo.Pakatikati pa ARM9 ili ndi malangizo apadera a 16-KB ndi ma cache a data a 16-KB.Ma cache onsewa ndi 4-way associative with virtual index virtual tag (VIVT).Pakatikati pa ARM9 ilinso ndi 8KB ya RAM (Vector Table) ndi 64KB ya ROM.Chipangizo cha DSP pachimake chimagwiritsa ntchito mamangidwe a 2-level cache-based.Cache ya pulogalamu ya Level 1 (L1P) ndi 32- KB yosungidwa mwachindunji, ndipo mulingo wa 1 data cache (L1D) ndi 32-KB 2-way, set-associative cache.Cache ya pulogalamu ya 2 (L2P) imakhala ndi malo okumbukira a 256-KB omwe amagawidwa pakati pa pulogalamu ndi data.Kukumbukira kwa L2 kumatha kukhazikitsidwa ngati kukumbukira kwamapu, cache, kapena kuphatikiza ziwirizi.Ngakhale kuti DSP L2 imapezeka ndi ARM9 ndi makamu ena mudongosolo, 128KB yowonjezera ya RAM yogawana kukumbukira ikupezeka kuti igwiritsidwe ntchito ndi makamu ena popanda kukhudza ntchito ya DSP.
