Khoom piav qhia
Nrog rau kev txhim kho txuas ntxiv ntawm thev naus laus zis, kev kub ceev serial VO thev naus laus zis tau dhau los ua cov qauv tam sim no los hloov cov cuab yeej sib luag I / O. Qhov ceev tshaj plaws thaum uas tig mus lub tsheb npav interface ceev yog 133 MB / s ntawm ATA7. Tus nqi hloov pauv tau muab los ntawm SATA1.0 specification tso tawm hauv 2003 tau mus txog 150 MB/s, thiab qhov theoretical ceev ntawm SATA3.0 tau mus txog 600 MB/s. Thaum lub cuab yeej ua haujlwm ntawm kev kub ceev, lub tsheb npav thaum uas tig mus ua rau muaj kev cuam tshuam thiab kev sib tham sib tham, ua rau kev sib txuas lus nyuaj heev. Kev siv ntawmserial transceiverstuaj yeem ua kom yooj yim layout tsim thiab txo tus naj npawb ntawm cov connectors. Nrog tib lub tsheb npav bandwidth, lub zog noj ntawm lub serial interface kuj tseem me dua li ntawm qhov chaw nres nkoj sib npaug. Thiab hom kev ua haujlwm ntawm cov cuab yeej hloov pauv los ntawm kev sib kis mus rau qhov sib txuas mus rau serial kis tau tus mob thiab cov serial ceev tuaj yeem ua ob npaug raws li qhov ntau zaus.
Raws li FPGA qhov zoo ntawm embedded GB tus nqi qib thiab qis zog noj architecture, nws ua rau cov neeg tsim qauv siv cov cuab yeej ua haujlwm siab EDA kom daws tau qhov teeb meem ntawm kev cai thiab kev hloov pauv sai. Nrog rau kev siv dav dav ntawm FPGAs, kev sib koom ua ke ntawm transceivers rau hauv FPGAs tau dhau los ua txoj hauv kev zoo los daws cov teeb meem ntawm cov khoom siv sib kis ceev.
Kev faib tawm
Raws li kev tswj hwm network, nws tuaj yeem muab faib ua kev tswj hwm network hom optical fiber transceiver thiab tsis yog network tswj homoptical fiber ntau transceiver.
Raws li lub network txhim kho mus rau qhov kev coj ua thiab tswj tau, feem ntau cov neeg ua haujlwm cia siab tias txhua yam khoom siv hauv lawv lub network tuaj yeem tswj tau nyob deb. Fiber optic transceiver cov khoom, zoo li cov keyboards thiab routers, yog maj mam txhim kho nyob rau hauv cov kev taw qhia no. Cov kev tswj xyuas network ntawm cov tuam txhab lag luam feem ntau yog tsim los ntawm SNMP network raws tu qauv thiab txhawb ntau txoj kev tswj hwm suav nrog Web, Telnet, thiab CLI. Cov ntsiab lus ntawm kev tswj hwm suav nrog kev teeb tsa kev ua haujlwm ntawm fiber ntau optic transceiver, saib xyuas hom module, kev ua haujlwm, qhov kub thiab txias, lub zog hluav taws xob, qhov hluav taws xob tso tawm thiab tso zis hluav taws xob ntawm fiber ntau optic transceiver thiab lwm yam. Raws li cov tswv lag luam xav tau ntau thiab ntau cov khoom siv network tswj, nws ntseeg tau tias kev tswj xyuas network ntawm optical fiber transceivers yuav ua tau zoo dua thiab ntse.
Optical fiber ntau transceiversrhuav tshem 100-meter txwv ntawm Ethernet cables hauv kev xa cov ntaub ntawv. Kev cia siab rau kev ua haujlwm siab hloov cov chips thiab lub peev xwm loj buffers, thaum ua tiav qhov tsis thaiv kev sib kis thiab hloov kev ua tau zoo, lawv kuj muab kev sib npaug ntawm kev sib tw, kev sib cais ntawm kev tsis sib haum xeeb thiab kev tshawb nrhiav yuam kev thiab lwm yam haujlwm ua kom muaj kev ruaj ntseg thiab ruaj khov thaum cov ntaub ntawv xa mus. Yog li ntawd, rau lub sijhawm ntev, cov khoom siv fiber ntau optic transceiver tseem yuav yog ib feem tseem ceeb ntawm kev tsim network tiag tiag. Nyob rau hauv lub neej yav tom ntej, fiber ntau optic transceivers yuav txuas ntxiv txhim kho nyob rau hauv cov kev taw qhia ntawm kev txawj ntse, kev ruaj ntseg siab, kev tswj xyuas network, thiab tus nqi qis.
Lub high-ceev transceiver ua rau nws muaj peev xwm xa tau ib tug loj npaum li cas ntawm cov ntaub ntawv point-to-point. Qhov kev sib txuas lus serial no ua rau kev siv tag nrho ntawm lub peev xwm ntawm cov kis nruab nrab. Piv nrog rau cov ntaub ntawv thaum uas tig mus, nws txo qhov yuav tsum tau sib kis channel thiab tus naj npawb ntawm cov cuab yeej pins, yog li txo cov nqi sib txuas lus zoo heev. Lub transceiver nrog kev ua tau zoo heev yuav tsum muaj qhov zoo ntawm kev siv hluav taws xob tsawg, me me, kev teeb tsa yooj yim, kev ua haujlwm siab, thiab lwm yam, kom nws tuaj yeem yooj yim sib xyaw rau hauv lub tsheb npav. Nyob rau hauv lub high-ceev serial cov ntaub ntawv kis raws tu qauv, kev ua tau zoo ntawm lub transceiver plays lub luag hauj lwm txiav txim siab nyob rau hauv tus nqi kis tau tus mob ntawm lub tsheb npav interface, thiab kuj muaj feem xyuam rau cov kev ua tau zoo ntawm lub tsheb npav interface system rau ib tug tej yam. Qhov kev tshawb fawb no txheeb xyuas qhov kev siv ntawm high-speed transceiver modules ntawm FPGA platform, thiab tseem muab cov ntaub ntawv siv tau zoo rau kev siv ntau yam kev sib txuas ceev ceev.
