TI's KeyStone architecture na-enye usoro mmemme nke na-ejikọta sistemu dị iche iche (Cores C66x, subsystem memory, peripherals, and accelerators) ma na-eji ọtụtụ ihe ọhụrụ na usoro iji bulie intradevice na nkwurịta okwu interdevice nke na-ahapụ ụdị DSP dị iche iche na-arụ ọrụ nke ọma na n'enweghị nsogbu.Central na ụkpụrụ ụlọ a bụ isi ihe dị ka Multicore Navigator nke na-enye ohere maka njikwa data nke ọma n'etiti ngwa ngwaọrụ dị iche iche.TeraNet bụ akwa mgba ọkụ na-anaghị egbochi ya na-eme ka mmegharị data dị n'ime ngwa ngwa na enweghị esemokwu.Ihe njikwa ebe nchekwa multicore na-enye ohere ịnweta ebe nchekwa nkekọrịta na nke mpụga ozugbo na-enweghị eserese site na ikike ngbanwe.Maka iji ihe eji eme ihe, isi C66x nwere 4 × ikike ịba ụba (MAC) nke C64x + cores.Na mgbakwunye, isi C66x na-ejikọta ike na-ese n'elu mmiri yana arụmọrụ mgbako nke kwa-isi bụ ụlọ ọrụ na-eduga 40 GMACS kwa isi yana 20 GFLOPS kwa isi (@1.25 GHz arụ ọrụ ugboro).Isi C66x nwere ike rụọ ọrụ MAC nke ọma 8 na-ese n'elu mmiri n'otu okirikiri ma nwee ike ịrụ ọrụ abụọ na nke ọma agwakọta yana IEEE 754 kwadoro.Isi C66x na-agụnye ntuziaka ọhụrụ 90 (tụnyere isi C64x+) ezubere iche maka nhazi ihe na-ese n'elu mmiri na mgbakọ na mwepụ vector.Nkwalite ndị a na-ewepụta nkwalite arụmọrụ dị oke na kernel DSP ewu ewu nke ejiri na nhazi mgbaama, mgbakọ na mwepụ na ọrụ nweta onyonyo.Isi C66x bụ koodu azụ azụ-dakọtara na ọgbọ nke TI gara aga C6000 nke edobere na isi ihe DSP, na-ahụ na mbugharị ngwanrọ na okirikiri mmepe ngwanrọ dị mkpụmkpụ maka ngwa na-akwaga na ngwaike ngwa ngwa.C665x DSP na-ejikọta nnukwu ebe nchekwa na mgbawa.Na mgbakwunye na 32KB nke mmemme L1 na cache data, 1024KB nke ebe nchekwa raara onwe ya nye nwere ike ịhazi ya dị ka RAM ma ọ bụ ihe nchekwa.Ngwa ahụ na-ejikọta 1024KB nke Multicore Shared Memory nke enwere ike iji dị ka L2 SRAM na / ma ọ bụ nkekọrịta L3 SRAM.Ihe ncheta L2 niile na-agụnye nchọta mperi na mgbazi mperi.Maka ịnweta ngwa ngwa na ebe nchekwa mpụga, ngwaọrụ a gụnyere 32-bit DDR-3 interface ebe nchekwa mpụga (EMIF) na-agba ọsọ na ọnụego 1333 MHz ma nwee nkwado ECC DRAM.
