Kev piav qhia
TSB83AA23 yog ib qho kev sib koom ua ke IEEE Std 1394b-2002 txuas-txheej tswj (LLC) tsim thiab txheej txheej lub cev (PHY) tsim ua ke hauv ib pob kom tau raws li qhov xav tau ntawm 1394 daim ntawv thov tsheb npav niaj hnub no. TSB83AA23 ntaus ntawv muaj peev xwm tshwj xeeb 800-Mbps kev ua haujlwm; yog li, muab cov kev nkag mus thiab bandwidth txav cov ntaub ntawv kom zoo thiab nrawm ntawm PCI thiab 1394 tsheb npav. TSB83AA23 ntaus ntawv tseem muab kev ua haujlwm zoo tshaj plaws ntawm lub zog qis thiab muaj peev xwm tswj hwm lub zog ntse. Cov cuab yeej muab IEEE 1394 LLC muaj nuj nqi thiab PHY muaj nuj nqi thiab sib xws nrog 100-Mbps, 200-Mbps, 400-Mbps, thiab 800-Mbps serial-bus cov ntaub ntawv tus nqi.
TSB83AA23 ua haujlwm raws li qhov sib txuas ntawm 33-MHz/32- ntsis PCI lub tsheb npav hauv zos thiab IEEE Std 1394a-2000 lossis IEEE Std 1394b-2002 serial-bus interface. Nws muaj peev xwm txhawb nqa cov ntaub ntawv serial ntawm 98.304, 196.608, 393.216, 491.52, lossis 786.432 Mbps (hu ua S100, S200, S400, S400B, lossis S800 speeds, ntsig txog). Thaum ua raws li PCI tus tswv tsheb npav, TSB83AA23 ntaus ntawv muaj peev xwm ntawm ntau lub cache-line tawg ntawm cov ntaub ntawv, uas tuaj yeem hloov ntawm 132M bytes / s rau 32- hloov pauv me ntsis tom qab txuas rau lub cim xeeb tswj. Vim tias muaj peev xwm dhau los ntawm TSB83AA23 ntaus ntawv, nws tuaj yeem ntsib PCI loj thiab legacy1394 tsheb npav latencies, uas tuaj yeem ua rau 1394 cov ntaub ntawv dhau mus. Txhawm rau kov yeej qhov teeb meem no, TSB83AA23 siv qhov sib sib zog nqus xa mus thiab tau txais FIFOs kom tsis txhob 1394 cov ntaub ntawv, yog li, tiv thaiv cov teeb meem tshwm sim vim lub tsheb npav latency. Qhov no kuj ua kom paub tseeb tias lub cuab yeej tuaj yeem xa thiab tau txais kev txhawb nqa
Qhov siab tshaj plaws-loj isochronous lossis asynchronous cov ntaub ntawv them nyiaj ntawm S800.
Tshooj TSB83AA23 LLC siv lwm yam kev ua tau zoo los txhim kho kev ua tau zoo tag nrho ntawm cov cuab yeej, xws li cov ntaub ntawv lub cev muaj zog rau kev txhim kho SBP-2 kev ua tau zoo, kev sau ntawv lub cev tsis muaj zog, ntau lub ntsiab lus isochronous, thiab kev txiav txim siab sab hauv siab. TSB83AA23 LLC ntu kuj tseem siv kho vajtse txhim kho kom zoo dua kev txhawb nqa digital video (DV) thiab
MPEG cov ntaub ntawv kwj txais thiab kis tau tus mob. Cov kev txhim kho no tau qhib los ntawm isochronous tau txais digital video txhim kho npe ntawm TI extension offset A80h. Cov kev txhim kho no suav nrog lub sijhawm tsis siv neeg-stamp tso rau kis DV thiab MPEG-formatted kwj, thiab cov pob ntawv isochronous (CIP) header stripping rau DV kwj.
CIP hom yog txhais los ntawm IEC 61883-1: 1998 specification. Qhov kev txhim kho rau cov ntaub ntawv isochronous cov ntsiab lus tau siv los ua cov khoom siv txhawb nqa rau lub sijhawm synchronization stamp rau ob qho tib si DV thiab audio / video CIP hom. TSB83AA23 ntaus ntawv txhawb kev hloov kho ntawm synchronization lub sij hawm-stamp teb kom paub meej tias tus nqi tso ntawm software tsis stale - uas yog, tsawg dua lub voj voog timer tam sim no thaum lub pob ntawv xa mus.
TSB83AA23 kev ua tau zoo thiab kev txhim kho dhau los ua rau nws yog qhov kev xaiv zoo tshaj plaws rau hnub no 1394 PC kev ua lag luam; Txawm li cas los xij, portable, mobile, thiab txawm tias desktop PC fais fab kev tswj cov txheej txheem txuas ntxiv xav kom cov cuab yeej siv hluav taws xob tsawg thiab tsawg dua, thiab TI's 1394 cov khoom lag luam tau txuas ntxiv nce qhov bar los ntawm kev muab cov khoom siv qis tshaj 1394 hauv kev lag luam. TSB83AA23 ntaus ntawv sawv cev rau kev hloov pauv tom ntej ntawm TI kev cog lus kom ua tau raws li qhov kev sib tw ntawm cov ntawv thov hluav taws xob. TSB83AA23 cov cuab yeej muaj lub zog ua haujlwm siab heev thiab muaj peev xwm tswj xyuas lub zog muaj peev xwm uas tso cai rau nws txuag lub zog ntawm nws tus kheej raws li lub cuab yeej.
kev siv. Tshooj TSB83AA23 LLC txhawb nqa tag nrho D0, D1, D2, thiab D3hot/cold power states, raws li tau teev tseg hauv PC 2001 Design Guide requirements and the PCI Power Management Specification. PME kev txhawb nqa kev tshwm sim yog raug rau kev txhawb nqa kev ua haujlwm thiab kev siv.
Raws li qhov yuav tsum tau ua los ntawm 1394 Qhib Lub Tswv Cuab Tswj Tus Kheej Interface Specification (OHCI) thiab IEEE Std 1394a-2000, kev tswj xyuas sab hauv yog lub cim xeeb mapped thiab tsis tuaj yeem rov qab tau. PCI configuration header yog nkag los ntawm kev teeb tsa lub voj voog raws li tau teev tseg los ntawm PCI Local Bus Specification, thiab muab plug-and-play (PnP) compatibility. Tsis tas li ntawd, ntu TSB83AA23 LLC tau ua raws li qhov tseeb PCI Local Bus Specification, PCI Bus Power Management Interface Specification, IEEE Std 1394b-2002, IEEE Std 1394a-2000,
thiab 1394 Qhib Lub Tswv Cuab Tswj Tus Kheej Interface Specification.
