Tsanangudzo

TI's KeyStone architecture inopa inorongwa chikuva inobatanidza akasiyana masisitimu (C66x cores, memory subsystem, peripherals, uye accelerators) uye inoshandisa akati wandei ekugadzira zvinhu uye matekiniki ekuwedzera intradevice uye interdevice kutaurirana izvo zvinoita kuti akasiyana DSP zviwanikwa zvishande nemazvo uye zvisina musono.Pakati peiyi dhizaini zvinhu zvakakosha zvakaita seMulticore Navigator inobvumira manejimendi e data pakati pezvakasiyana zvemidziyo.Iyo TeraNet ndeye isingavharike switch jira inogonesa kukurumidza uye kukakavara-isina yemukati data kufamba.Iyo multicore yakagovaniswa memory controller inobvumira kuwana yakagovaniswa uye yekunze ndangariro zvakananga pasina kudhirowa kubva kuchinjika machira kugona.Nekugadziriswa-point kushandiswa, iyo C66x musimboti ine 4 × iyo yakawedzera kuunganidza (MAC) kugona kweC64x + cores.Pamusoro pezvo, iyo C66x musimboti inosanganisa inoyangarara-poindi kugona uye iyo-yepakati-yakaomeswa computational kuita iindasitiri inotungamira makumi mana GMACS pamusimboti uye makumi maviri GFLOPS pamusimboti (@1.25 GHz inoshanda frequency).Iyo C66x musimboti unogona kuita masere chaiwo anoyangarara-poinzi MAC mashandiro pakutenderera uye anogona kuita kaviri- uye musanganiswa-chaiyo mashandiro uye iIEEE 754 inowirirana.Iyo C66x musimboti inosanganisira makumi mapfumbamwe mirairo mitsva (ichienzaniswa neC64x + musimboti) yakanangwa yekuyangarara-point uye vector math oriented processing.Izvi zvinowedzeredzwa zvinopa hukuru hwekuita kuvandudzwa mune dzakakurumbira DSP kernels dzinoshandiswa mukugadzirisa zviratidzo, masvomhu, uye mabasa ekutora mifananidzo.Iyo C66x musimboti ndeyekumashure kodhi-inoenderana neTI yechizvarwa chekare C6000 yakagadziriswa- uye inoyangarara-poinzi DSP cores, ichiva nechokwadi chekutakurika kwesoftware uye kupfupisa magadzirirwo esoftware maapplication ari kutamira kune nekukurumidza Hardware.Iyo C665x DSP inobatanidza huwandu hukuru hwe-on-chip memory.Pamusoro pe32KB yeL1 chirongwa uye data cache, 1024KB yeakazvitsaurira ndangariro inogona kugadzirwa semepu RAM kana cache.Chishandiso ichi chinosanganisawo 1024KB yeMulticore Shared Memory iyo inogona kushandiswa seyakagovaniswa L2 SRAM uye/kana yakagovaniswa L3 SRAM.Yese L2 ndangariro dzinosanganisira kuona kukanganisa uye kugadzirisa kukanganisa.Kuti uwane nekukurumidza kundangariro yekunze, mudziyo uyu unosanganisira 32-bit DDR-3 yekunze memory interface (EMIF) inomhanya pamwero we1333 MHz uye ine ECC DRAM rutsigiro.
