Incazelo

Isakhiwo se-KeyStone se-TI sinikeza inkundla ehlelekayo ehlanganisa amasistimu angaphansi ahlukahlukene (ama-C66x cores, i-memory subsystem, ama-peripherals, nama-accelerator) futhi isebenzisa izingxenye namasu amaningana amasha ukuze kukhuliswe ukuxhumana kwe-intradevice ne-interdevice okuvumela izinsiza ezahlukene ze-DSP zisebenze kahle futhi ngaphandle komthungo.Okubalulekile kulokhu kwakhiwa yizingxenye ezibalulekile ezifana ne-Multicore Navigator evumela ukuphathwa kahle kwedatha phakathi kwezingxenye ezihlukahlukene zedivayisi.I-TeraNet iyindwangu yokushintsha engavimbeli evumela ukunyakaza kwedatha yangaphakathi okusheshayo nokungenamibango.Isilawuli sememori eyabiwe ye-multicore sivumela ukufinyelela kumemori eyabiwe nangaphandle ngokuqondile ngaphandle kokudweba kusuka kumthamo wendwangu yokushintsha.Ngokusetshenziswa kwephoyinti elingashintshi, i-C66x core inamandla angu-4× wokuphindaphinda (MAC) wama-cores C64x+.Ukwengeza, i-C66x core ihlanganisa amandla ephoyinti elintantayo futhi ukusebenza kwekhompyutha kwe-per-core eluhlaza kungama-40 GMACS ahamba phambili embonini ngomongo ngamunye kanye no-20 GFLOPS ngomgogodla ngamunye (@1.25 GHz imvamisa yokusebenza).I-C66x core ingakwazi ukwenza imisebenzi ye-MAC yephoyinti elintantayo eyi-8 enembayo umjikelezo ngamunye futhi ingenza imisebenzi ephindwe kabili nenembayo futhi ithobela i-IEEE 754.I-C66x core ihlanganisa imiyalelo emisha engu-90 (uma kuqhathaniswa ne-C64x+ core) eqondiswe endaweni entantayo kanye ne-vector math oriented processing.Lezi zithuthukisi ziveza ukuthuthukiswa kokusebenza okulinganiselwe kuma-kernel e-DSP adumile asetshenziswa ekucubunguleni isignali, imisebenzi yezibalo, kanye nokutholwa kwesithombe.I-C66x core iyikhodi ebuyela emuva ihambisana nesizukulwane sangaphambilini se-TI C6000 cores ye-DSP engaguquki kanye nephuzu elintantayo, iqinisekisa ukuphatheka kwesofthiwe kanye nemijikelezo yokuthuthukiswa kwesofthiwe emifushane yezinhlelo zokusebenza ezithuthela kuhadiwe esheshayo.I-C665x DSP ihlanganisa inani elikhulu lememori eku-chip.Ngokungeziwe ku-32KB yohlelo lwe-L1 kanye nenqolobane yedatha, i-1024KB yememori enikelwe ingalungiswa njenge-RAM efakwe kumephu noma inqolobane.Idivayisi iphinde ihlanganise u-1024KB we-Multicore Shared Memory engasetshenziswa njenge-L2 SRAM eyabiwe kanye/noma i-L3 SRAM eyabiwe.Zonke izinkumbulo ze-L2 zihlanganisa ukutholwa kwamaphutha nokulungiswa kwamaphutha.Ukuze uthole ukufinyelela okusheshayo kumemori yangaphandle, le divayisi ihlanganisa isixhumi esibonakalayo sememori yangaphandle engu-32-bit DDR-3 (EMIF) egijima ngenani elingu-1333 MHz futhi inosekelo lwe-ECC DRAM.
