Whakaahuatanga

Ko te hoahoanga KeyStone a TI e whakarato ana i te papaaho ka taea te whakauru i nga momo punaha iti (C66x cores, subsystem mahara, peripheral, me te whakatere) me te whakamahi i nga waahanga me nga tikanga hou hei whakanui ake i te whakawhitiwhitinga-a-roto me te whakawhitiwhiti whakaaro e taea ai e nga momo rauemi DSP te mahi pai me te pai.Ko te mea nui o tenei hoahoanga ko nga waahanga matua penei i te Multicore Navigator e taea ai te whakahaere raraunga pai i waenga i nga momo taputapu.Ko te TeraNet he papanga whakawhiti kore aukati e taea ai te neke tere me te kore tautohetohe o roto.Ka taea e te pūmana mahara tiritahi maha te uru ki te mahara tiritahi me te mahara o waho me te kore e tuhi mai i te kaha papanga whakawhiti.Mo te whakamahi ira-waahi, ko te C66x matua he 4x te kaha whakaemi (MAC) o C64x+ matua.I tua atu, ko te C66x matua e whakauru ana i te kaha o te maanu-tohu me te mahinga o te mahinga rorohiko mata-a-umanga he 40 GMACS e arahi ana i te ahumahi me te 20 GFLOPS mo ia matua (@1.25 GHz te auau mahi).Ka taea e te matua C66x te whakahaere i nga mahinga MAC maanu-waahi kotahi e 8 mo ia huringa ka taea te mahi i nga mahi rua-rua me te whakauru-tika me te whai IEEE 754.Ko te matua C66x he 90 nga tohutohu hou (i whakaritea ki te C64x+ matua) e whaaia ana mo te tukatuka i runga i te tohu maanu me te pangarau vector.Ko enei whakapainga ka nui ake nga whakapainga mahi i roto i nga kakano DSP rongonui e whakamahia ana i roto i te tukatuka tohu, te pangarau, me nga mahi tango whakaahua.Ko te matua C66x he whakamuri-waehere-hototahi ki nga reanga o mua a TI C6000 kua pumau- me te maanu-ira DSP, e whakarite ana i te kawe rorohiko me te whakapoto i nga huringa whanaketanga rorohiko mo nga tono e heke ana ki nga taputapu tere ake.Ko te C665x DSP e whakauru ana i te nui o te mahara ki runga maramara.I tua atu i te 32KB o te kaupapa L1 me te keteroki raraunga, 1024KB o te mahara whakatapua ka taea te whirihora hei RAM mapi, keteroki ranei.Ka whakauru ano hoki te taputapu i te 1024KB o te Mahara Tiri Mahaka Ka taea te whakamahi hei L2 SRAM tiritahi me/ranei L3 SRAM tiritahi.Ko nga mahara L2 katoa e whakauru ana i te kitenga hapa me te whakatika hapa.Mo te uru tere ki te mahara o waho, kei roto i tenei taputapu he 32-bit DDR-3 atanga mahara o waho (EMIF) e rere ana i te tere o te 1333 MHz me te tautoko ECC DRAM.
