Indasteri ea likoloi e ntse e hlalosoa bocha ka nts'etsopele e potlakileng ea theknoloji ea tlhahisoleseling le khokahanyo.Litheknoloji tsa ho khanna li etsa hore ho be le maemo a ntseng a eketseha a likoloi likoloing, moo pono ea k'homphieutha e fetelang butle-butle ho neural network AI, e re lumellang ho ntlafatsa ho khanna ka mokhoa o ikemetseng ka mokhoa o hlophisitsoeng.Ntle le tikoloho ea kantle ea koloi, ho na le mokhoa o moholo o lebisang tlhokomelo e ntlafalitsoeng ea kahare, ea mokhanni le bapalami.Ts'ebeliso ea mahlale a ka mpefalang ts'ebetsong ena e ka etsa hore ho be le phetoho e kholo indastering, ho kenyeletsoa le phetoho ea lipalangoang le phano ea litšebeletso, hammoho le mekhoa ea khoebo e sa tsoa qala.

E le mofani ea ka sehloohong oa lefats'e oa litharollo tse felletseng bakeng sa logic e ka khonehang, Xilinx e na le lihlahisoa tse fapaneng lekaleng la likoloi, tse koahelang lits'ebetso tse fapaneng tse fapaneng ka koloing.Haufinyane tjena, Xilinx e phatlalalitse lihlahisoa tse peli tse ncha, ZU7EB7 le ZU7EB11, ha e ntse e nka theknoloji ea ho khanna e ikemetseng boemong bo bocha.Sebokeng se le seng sa boralitaba, Dan Isaacs, Motsamaisi oa Leano la Likoloi le Papatso ea Bareki Xilinx, o ile a arolelana likarolo tsa lihlahisoa tsa Xilinx, melemo ea FPGAs, le theknoloji ea ho khanna e ikemetseng.

Ho kopanya ho ikamahanya le maemo, scalability

Mabapi le semelo le boiphihlelo, Xilinx o na le boiphihlelo bo tebileng haholo lefapheng la likoloi.Ho tloha ho fana ka mefuta e 14 le mefuta e 29 ka 2014, e se e holile ho ea ho mefuta e 29 le mefuta e 111 ka 2018. Ka ho khanna ka boithaopo, lihlahisoa tsa Xilinx li teng lihlahisoa le liforomo tse ngata tsa bahlahisi, ho kenyeletsoa Apollo ea Baidu, BYD, Daimler, Magna, ZF, le Pony Smart.Dan Isaacs o hlalositse lisebelisoa tsa sehlahisoa sa Xilinx e le tse koahelang litlhoko tsohle tsa bareki ho tloha ho tse nyane ho isa ho tse kholo, ekaba ke li-sensor kapa li-pre-control bakeng sa ts'ebetso e bohareng.

Tseleng ea ho hlahloba theknoloji ea ho khanna e ikemetseng, bahlahisi ba bang ba setso ba atisa ho ea pele ho li-detectors tsa ring ring, ho tloha ka ntle ho koloi ho ea ka hare ho koloi, ebe ba etsa li-pre-controller tsa ADAS joalo-joalo.Likhamphani tsa thekenoloji ea Marang-rang tse kang Baidu, li na le tšekamelo ea ho khetha tsela e 'ngoe eo e seng ea setso le ho sebelisa mokhoa oa ho etsa li-modules tsa tšebetso tse bohareng ka kotloloho ho fihlela ho khanna ka boikemelo.Hajoale, lihlahisoa le tharollo ea Xilinx li koahetse likarolo tsohle litseleng ka bobeli.Ka mohlala, LiDAR, lik'hamphani tse fetang 30 li sebelisa lihlahisoa le mahlale a Xilinx.

Dan Isaacs o boletse hore potso ea ho sireletseha e lula e le likelellong tsa Xilinx.Ha litlhoko tsa li-sensor li ntse li eketseha, ho joalo le ka litlhoko tsa ts'ebetso ea data, e hlokang hore lisebelisoa tsena le lisebelisoa tse ka koloing li fokotsehe.Ts'ebetso le thekenoloji ea Xilinx Autonomous Driving Central Module, ka bobeli mabapi le ho kopanya data le sensor fusion, e bonts'a hape hore theknoloji ea Xilinx e senyeha haholo, ho tloha ho lisebelisoa tse nyane haholo ho isa ho tse kholo haholo.

Ntle le moo, lihlahisoa tsa Xilinx le li-chips li ikamahanya le maemo haholo 'me li ka fihlela litlhoko tse fetohang, ebang li hloka li-sensor tse ngata kapa ts'ebetso e phahameng ea komporo.Ka mohlala, LIDAR, ho na le lik'hamphani tse fetang 50 tsa LIDAR, 'me kaofela li sebetsana le data le ho bokella lintlha ka litsela tse sa tšoaneng, kahoo li batla ho khona ho bokella lintlha ka litsela tse sa tšoaneng.Dan Isaacs o hatelletse hore ke sehlahisoa se senyehileng le se feto-fetohang feela se ka kopanang le phetisetso ea kamehla ea lihlahisoa le mahlale.

Theknoloji le lihlahisoa tse ikhethang le tse molemo

Litsamaisong tsa ho khanna tse ikemetseng, fusion ea sensor ke tataiso ea bohlokoa haholo, e ka kopanyang melemo ea li-sensor tse fapaneng ho fana ka tlhahiso e ntle ea matšoao.U sebelisa litharollo tsa Xilinx's FPGA, ho kopanngoa ha matšoao a sensor ho ka sebelisoa hamolemo, ka hona ho fana ka melemo e meholo le bonolo ho sistimi ea kutlo.Dan Isaacs o boletse hore melemo e latelang e fanoa ke tharollo ea sehlahisoa sa Xilinx.

Ntlha ea pele, ts'ebetso e phahameng le latency e tlaase.Ka tloaelo, li-CPU tsa setso, li-GPU, kapa li-DSP li ka fihlela katleho e phahameng, empa eseng latency e tlase.Ka tharollo ea Xilinx FPGA, phallo e phahameng le latency e tlaase e ka finyelloa ka nako e le 'ngoe, ka keketseho ea 12x ea bokhoni bo loketseng le 1/10th ea tšebeliso ea matla ea meralo ea meralo ea lik'homphieutha ka kakaretso, ho phaella ho nako e matla haholo.

Taba ea bobeli, e nolofalletsa on-chip le in-run reconfiguration.Sena se boetse se amana le sebopeho sa eona sa ho ikamahanya le maemo, kaha lihlahisoa le theknoloji ea Cyrix ha e hloke ho hlahisoa ha lisebelisoa tse ncha ho thusa ho lokisa hang-hang.Mohlala, ho protocol ea MIPI, moo litefiso tsa data li ntseng li eketseha, litharollo tsa FPGA ha li hloke ho fetola lisebelisoa tsa mantlha empa li ka ts'ehetsa litefiso tse phahameng tsa data ka liphetoho tse hlophisitsoeng tsa logic.

Hape, tharollo ea Xilinx's FPGA e na le DFX, kapa Dynamic Function Exchange, bokhoni.Ha ho na tlhoko ea ho qala kapa ho tima lisebelisoa ho fetola mesebetsi lipakeng tsa tsona.Ka mohlala, I / O kapa li-sensor ha li hloke ho fetoloa haholo, empa ke karolo feela ea logic e hlophisitsoeng e sebelisetsoang phetoho.

Ka bokhutšoanyane, ntle le ts'ebetso e phahameng le latency e tlase, lihlahisoa le mahlale a Xilinx li ka thusa bareki ho fihlella phetoho e matla ea ts'ebetso kapa lisebelisoa tse hole, ke hore, lintlafatso tsa chip, ka logic e hlophisehileng.Sena se lumella hore ho be le tharollo e pharaletseng haholo le e ka senyehang, ho kenyelletsa le litlhoko tsa I / O bakeng sa tlhahisoleseding ea ho lemoha, hammoho le bokhoni ba ho potlakisa, le bokhoni ba ho bokella, ho hlophisa pele le ho aba lintlha.Bokhoni ba ho bokella lintlha tsohle ho tsoa ho lisebelisoa tse nyane tse pheletsong bakeng sa ts'ebetso, ebe o li sebetsa ka sesebelisoa se seholo, e leng setsi sa pele sa processor.Hammoho le ADAS, sena se nolofalletsa likhomphutha tse fapaneng, tse thusang lienjineri tsa vector, lienjineri tsa AI, le lienjineri tse fapaneng ho fihlela likhomphutha tse fapaneng.
