Kev piav qhia
OMAP-L138 C6000 DSP + ARM processor yog lub zog siv hluav taws xob tsawg raws li ARM926EJ-S thiab C674x DSP core.Cov txheej txheem no muab lub zog qis dua li lwm tus tswv cuab ntawm TMS320C6000 ™ platform ntawm DSPs.Cov cuab yeej ua rau cov tuam txhab tsim khoom qub (OEMs) thiab cov tuam txhab tsim qauv qub (ODMs) kom sai sai coj mus rau cov khoom lag luam nrog cov kev ua haujlwm zoo, cov neeg siv nplua nuj interfaces, thiab kev ua haujlwm siab ntawm cov txheej txheem los ntawm qhov siab tshaj plaws ntawm kev sib xyaw ua ke, cov txheej txheem sib xyaw ua ke.Lub dual-core architecture ntawm lub cuab yeej muab cov txiaj ntsig ntawm DSP thiab txo cov kev qhia teeb tsa lub khoos phis tawj (RISC) thev naus laus zis, suav nrog kev ua haujlwm siab TMS320C674x DSP core thiab ARM926EJ-S core.ARM926EJ-S yog 32-ntsis RISC processor core uas ua haujlwm 32-ntsis lossis 16-ntsis cov lus qhia thiab cov txheej txheem 32-, 16-, lossis 8-ntsis cov ntaub ntawv.Cov tub ntxhais siv cov raj xa dej kom txhua qhov chaw ntawm lub processor thiab lub cim xeeb tuaj yeem ua haujlwm tsis tu ncua.ARM9 core muaj ib tug coprocessor 15 (CP15), kev tiv thaiv module, thiab cov ntaub ntawv thiab cov kev pab cuam lub cim xeeb tswj units (MMUs) nrog lub rooj saib-sib sab buffers.ARM9 core muaj cais 16-KB kev qhia thiab 16-KB cov ntaub ntawv caches.Ob lub caches yog 4-txoj kev sib koom nrog virtual index virtual tag (VIVT).ARM9 core kuj muaj 8KB ntawm RAM (Vector Table) thiab 64KB ntawm ROM.Cov cuab yeej DSP core siv 2-theem cache-based architecture.Qib 1 program cache (L1P) yog 32- KB ncaj qha mapped cache, thiab qib 1 cov ntaub ntawv cache (L1D) yog 32-KB 2-txoj kev, teeb tsa-kev koom ua ke cache.Qib 2 qhov kev pab cuam cache (L2P) muaj 256-KB qhov chaw nco uas tau sib koom ntawm qhov program thiab cov ntaub ntawv chaw.L2 lub cim xeeb tuaj yeem teeb tsa raws li mapped nco, cache, lossis kev sib txuas ntawm ob.Txawm hais tias DSP L2 tuaj yeem nkag tau los ntawm ARM9 thiab lwm tus tswv hauv lub cev, ntxiv 128KB ntawm RAM sib koom nco muaj rau siv los ntawm lwm tus tswv yam tsis cuam tshuam rau DSP kev ua haujlwm.
