TMS320C6657CZHA IC DSP FIX/FLOAT POINT 625FCBGA

Kev piav qhia

TI's KeyStone architecture muab lub programmable platform sib koom ua ke ntau yam subsystems (C66x cores, nco subsystem, peripherals, thiab accelerators) thiab siv ob peb lub tswv yim tshiab thiab cov tswv yim los ua kom loj tshaj intradevice thiab interdevice kev sib txuas lus uas cia ntau yam DSP kev pab cuam khiav hauj lwm zoo thiab seamlessly.Lub hauv paus rau cov qauv no yog cov khoom tseem ceeb xws li Multicore Navigator uas tso cai rau kev tswj cov ntaub ntawv zoo ntawm ntau yam khoom siv.TeraNet yog cov ntaub ntawv hloov pauv uas tsis muaj kev thaiv kev ua kom nrawm thiab tsis muaj kev sib cav-dawb cov ntaub ntawv sab hauv.Lub multicore sib koom nco xws li tso cai rau kev nkag mus rau kev sib koom thiab sab nraud nco ncaj qha yam tsis tau kos duab los ntawm kev hloov ntaub muaj peev xwm.Rau kev siv cov ntsiab lus tas, C66x cores muaj 4 × qhov sib npaug (MAC) muaj peev xwm ntawm C64x + cores.Tsis tas li ntawd, C66x core integrates floating-point peev xwm thiab ib-core raw computational kev ua tau zoo yog kev lag luam-ua 40 GMACS ib core thiab 20 GFLOPS ib core (@1.25 GHz kev khiav hauj lwm zaus).Cov tub ntxhais C66x tuaj yeem ua tiav 8 ib qho kev ua haujlwm ntawm MAC hauv ib lub voj voog thiab tuaj yeem ua haujlwm ob npaug thiab sib xyaw ua haujlwm thiab ua raws IEEE 754.Lub C66x core suav nrog 90 cov lus qhia tshiab (piv rau C64x + core) tsom rau kev ua lej thiab vector lej taw qhia.Cov kev txhim kho no ua rau muaj txiaj ntsig zoo txhim kho hauv DSP kernels nrov siv hauv kev ua cov teeb liab, lej, thiab cov duab nrhiav tau.C66x core yog rov qab code-tshaj nrog TI cov tiam dhau los C6000 tsau- thiab ntab-point DSP cores, kom ntseeg tau tias software portability thiab shortened software kev loj hlob mus rau kev siv migrating mus rau hardware sai.C665x DSP integrates ib tug loj npaum li cas ntawm on-chip nco.Ntxiv rau 32KB ntawm L1 kev pab cuam thiab cov ntaub ntawv cache, 1024KB ntawm kev mob siab rau lub cim xeeb tuaj yeem teeb tsa raws li mapped RAM lossis cache.Cov cuab yeej tseem koom nrog 1024KB ntawm Multicore Shared Memory uas tuaj yeem siv los ua L2 SRAM sib koom thiab / lossis sib koom L3 SRAM.Txhua qhov L2 nco suav nrog kev tshawb pom qhov yuam kev thiab kho qhov yuam kev.Rau kev nkag mus ceev rau sab nraud nco, cov cuab yeej no suav nrog 32-ntsis DDR-3 sab nraud nco interface (EMIF) khiav ntawm tus nqi ntawm 1333 MHz thiab muaj ECC DRAM kev txhawb nqa.
