Yuav ua li cas thiab hloov GMSL rau PCLE siv Serdes?

Txhawm rau hloov GMSL cim rau PCI cov cim ntawm Serdes, cov kauj ruam hauv qab no feem ntau yog koom nrog:

1. Serialization (GMSL rau cov ntaub ntawv)

Serializes: GMSL cuam tshuam feem ntau muaj cov ntaub ntawv kis tau zoo. Cov Serializer hloov pauv cov ntaub ntawv los ntawm cov cuab yeej siv (xws li lub koob yees duab, sensor, lossis FPGA) mus rau hauv lub teeb tsa siab-nrawm uas tuaj yeem kis tau los ntawm GMSL.
GMSL Serializer: Ib GMSL Serializer IC yog qhov yuav tsum tau ua, uas hloov siab cov ntaub ntawv ntawm lub koob yees duab lossis sensor rau serialized GMSL cim. Cov phiajcim no tau sib kis tau ntau dua cov khub cable lossis ob khub khub.

2. Kev sib kis ntawm GMSL

GMSL Cable: serialized cov ntaub ntawv yog kis tau los ntawm GMSL Cable, feem ntau yog siv Fakra txuas lossis cov coaxial cable. GMSL cov kev txuas tuaj yeem xa cov ntaub ntawv nkaus xwb, tab sis kuj muaj zog thiab tswj cov cim nyob ntawm GMSL (GMSL2, GMSL2 lossis GMSL3).

3. Kev dag zog (cov ntaub ntawv rau PCIE)

Kev xav: ntawm qhov tau txais kawg, qhov desererizer hloov dua cov kab mob serial ntws rov qab rau hauv cov ntaub ntawv sib piv. Desererializers feem ntau muaj peev xwm lis ob GMSL thiab PCIOLOLOLs.
GMSL rau PCIE Desererializer ic: GMSL rau PCIE deserialer yuav tsum muaj. Cov khoom siv hloov pauv no tau txais cov ntaub ntawv GMSL rau hauv hom ntawv uas tuaj yeem ua tiav los ntawm PCIie xaus ntaus ntawv lossis daim npav.

4. PCI pcie Bridging

PCIE Bridging: Tom qab cov ntaub ntawv yog desererized, nws yuav tsum tau mapped rau pcie raws tu qauv los ntawm PCIE choj IC lossis PCIE hloov. Tus choj hloov pauv cov ntaub ntawv sib txuas rau hauv PCE tau sib xws, uas tuaj yeem hloov mus rau cov ntaub ntawv PCA tau sib haum xeeb ntawm cov khoom siv (xws li cov koob yees duab (xws li cov koob yees duab lossis lub sensors) thiab cov tshuab pcie.
