Zomangamanga za TI's KeyStone zimapereka nsanja yosinthika yophatikiza ma subsystems osiyanasiyana (C66x cores, memory subsystem, peripherals, and accelerators) ndipo amagwiritsa ntchito zida zingapo zatsopano kuti apititse patsogolo kulumikizana kwa intradevice ndi interdevice komwe kumapangitsa kuti zida zosiyanasiyana za DSP zizigwira ntchito bwino komanso mosasunthika.Pakatikati mwazomangamangazi ndi zigawo zikuluzikulu monga Multicore Navigator zomwe zimalola kuwongolera bwino kwa data pakati pa zida zosiyanasiyana.TeraNet ndi nsalu yosinthira yosatsekereza yomwe imathandizira kusuntha kwa data mkati mwachangu komanso kopanda mikangano.Wowongolera kukumbukira wogawana nawo wamitundu yambiri amalola mwayi wogawana nawo komanso wakunja kukumbukira mwachindunji popanda kujambula kuchokera pakusintha kwa nsalu.Pogwiritsa ntchito mfundo zokhazikika, C66x core ili ndi 4 × kuchulukitsa (MAC) mphamvu ya C64x + cores.Kuphatikiza apo, C66x core imaphatikizira kuthekera koyandama ndipo magwiridwe antchito amtundu uliwonse ndi 40 GMACS pachimake ndi 20 GFLOPS pachimake (@1.25 GHz opareshoni pafupipafupi).C66x pachimake imatha kugwira ntchito 8 zoyandama zoyandama za MAC pa kuzungulira ndipo imatha kuchita maopaleshoni awiri komanso osakanikirana ndipo imagwirizana ndi IEEE 754.C66x core imaphatikizanso malangizo 90 atsopano (poyerekeza ndi C64x+ core) omwe amayang'ana pakuyandama ndi ma vector masamu.Zowonjezera izi zimabweretsa kusintha kwakukulu kwa magwiridwe antchito mu ma kernels otchuka a DSP omwe amagwiritsidwa ntchito pokonza ma sign, masamu, ndi ntchito zopezera zithunzi.C66x pachimake ndi khodi yakumbuyo-yogwirizana ndi m'badwo wam'mbuyo wa TI C6000 wokhazikika- komanso woyandama wa DSP cores, kuwonetsetsa kusuntha kwa mapulogalamu ndikufupikitsa kakulidwe ka mapulogalamu a mapulogalamu omwe akusamukira ku hardware yachangu.C665x DSP imaphatikiza kukumbukira kwakukulu pa-chip.Kuphatikiza pa 32KB ya pulogalamu ya L1 ndi cache ya data, 1024KB yamakumbukidwe odzipatulira imatha kukhazikitsidwa ngati mapu a RAM kapena posungira.Chipangizochi chimaphatikizanso 1024KB ya Multicore Shared Memory yomwe ingagwiritsidwe ntchito ngati L2 SRAM yogawana ndi / kapena kugawana L3 SRAM.Zokumbukira zonse za L2 zimaphatikizapo kuzindikira zolakwika ndi kukonza zolakwika.Kuti mufike mwachangu kukumbukira zakunja, chipangizochi chimakhala ndi mawonekedwe a 32-bit DDR-3 akunja (EMIF) omwe akuyenda pamlingo wa 1333 MHz ndipo ali ndi chithandizo cha ECC DRAM.
