Meaho ea KeyStone ea TI e fana ka sethala se ka hlophisehang se kopanyang li-subsystem tse fapaneng (C66x cores, memory subsystem, peripherals, le accelerator) mme e sebelisa likarolo tse 'maloa tse ncha le mekhoa ea ho holisa puisano ea lisebelisoa le lisebelisoa tse lumellang lisebelisoa tse fapaneng tsa DSP ho sebetsa ka nepo le ka ntle ho seam.Bohareng ba mohaho ona ke likarolo tsa bohlokoa tse kang Multicore Navigator e lumellang hore ho be le tsamaiso e nepahetseng ea data pakeng tsa lisebelisoa tse sa tšoaneng tsa lisebelisoa.TeraNet ke lesela le sa thibeleng le lumellang motsamao oa data oa kahare o potlakileng le o se nang likhohlano.Taolo ea memori e arolelanoang ea multicore e lumella phihlello ea mohopolo o arolelanoang le oa kantle ka kotloloho ntle le ho hula ho tsoa ho matla a lesela.Bakeng sa tšebeliso ea lintlha tse tsitsitseng, C66x ea mantlha e na le 4 × matla a mangata a bokellang (MAC) a C64x + cores.Ntle le moo, C66x core e kopanya bokhoni ba lintlha tse phaphametseng 'me ts'ebetso ea khomphutha e tala ke 40 GMACS e etelletseng pele indastering le 20 GFLOPS ka mantlha (@1.25 GHz frequency operating).Mokotla oa C66x o ka etsa ts'ebetso ea MAC e 8 e nepahetseng e le 'ngoe ka potoloho e ngoe le e ngoe 'me e khona ho etsa ts'ebetso e nepahetseng habeli le e tsoakiloeng mme e lumellana le IEEE 754.Mokotla oa C66x o kenyelletsa litaelo tse ncha tse 90 (ha li bapisoa le C64x + core) tse lebisitsoeng bakeng sa ho sebetsa ka lipalo tse phaphametseng le vector.Lintlafatso tsena li fana ka ntlafatso e kholo ea ts'ebetso ho li-kernel tse tsebahalang tsa DSP tse sebelisoang ts'ebetsong ea mats'oao, mesebetsi ea lipalo le ea ho fumana litšoantšo.C66x ea mantlha e tsamaisana le khoutu ea morao-rao e tsamaellanang le li-cores tsa TI tsa C6000 tse tsitsitseng le tse phaphametseng tsa DSP, e netefatsang hore software e khona ho nkeha le ho khutsufatsa linako tsa nts'etsopele ea software bakeng sa lits'ebetso tse fallelang ho hardware e potlakileng.C665x DSP e kopanya palo e kholo ea memori ea on-chip.Ntle le 32KB ea lenaneo la L1 le cache ea data, 1024KB ea memori e inehetseng e ka hlophisoa joalo ka RAM kapa cache ea 'mapa.Sesebelisoa se boetse se kopanya 1024KB ea Multicore Shared Memory e ka sebelisoang e le L2 SRAM e arolelanoang le / kapa e arolelanoang L3 SRAM.Likhopotso tsohle tsa L2 li kenyelletsa ho lemoha liphoso le ho lokisa liphoso.Bakeng sa ho fihlella ka potlako mohopolong oa kantle, sesebelisoa sena se kenyelletsa sebopeho sa memori sa 32-bit DDR-3 (EMIF) se sebetsang ka sekhahla sa 1333 MHz mme se na le tšehetso ea ECC DRAM.
