Lub tswv yim ntawm industrial embedded computers

1. Los ntawm kev pom kev kho vajtse. Ua ke CPU-raws li peripheral li rau hauv CPU nti. Piv txwv li, hauv cov khoos phis tawj thaum ntxov raws li X86 architecture, CPU tsuas yog muaj lub luag haujlwm ntawm chav lej lej thiab cov khoom sib txuas. Tag nrho cov chips yuav tsum tau cia siab rau sab nraud txuas ntxiv kom nthuav dav thiab siv tau. Serial ports thiab cov zoo li tau siv los ntawm sab nraud 16C550/2 serial chaw nres nkoj maub los chips, thiab tam sim no serial chaw nres nkoj maub los chips tau ntev tau koom ua ke rau hauv CPU. PCs kuj muaj cov ntawv teev lus, thiab feem ntau cov txheej txheem embedded muaj LCD controllers, tab sis nyob rau hauv ib qho kev nkag siab lawv yog sib npaug rau cov duab phaib. IXP network processor CPU nyob rau hauv high-end ARM-based Intel Xscale architecture muaj ib qho kev sib xyaw PCI maub los (uas tuaj yeem teeb tsa los txhawb 4 PCI qhev pab kiag li lawm los yog teeb tsa ua CPI qhev ntaus ntawv nws tus kheej); nws kuj tseem koom ua ke 3 NPE network processor engines, ob qhov sib txuas rau ob qhov chaw nyob MAC thiab tuaj yeem siv rau kev hloov lub rooj vag, thiab lwm yam NPE network processor cav txhawb DSL. Ntev npaum li PHY nti ntxiv rau sab nraud, DSL kev siv Internet tuaj yeem ua tiav. IXP series tuaj yeem ncav cuag qhov siab tshaj plaws ntawm 1.8G, txhawb nqa 2G nco, 1G × 10 lossis 10G × 1 Ethernet chaw nres nkoj lossis Febre channel optical channel. IXP series yuav tsum yog lub processor siab tshaj plaws raws li ARM system qauv kev koom ua ke los ntawm Intel rau hauv Xscale core.
2. Los ntawm qhov kev pom ntawm software, nws yog xaiv cov ntawv thov hauv cov txheej txheem kev ua haujlwm ntawm cov ntsiav tshuaj, thiab rub tawm cov ntsiav mus rau ROM tom qab muab tso ua ke. Daim ntawv thov cov khoom xaiv xaiv thaum customizing lub operating system kernel yog "embedding" ntawm software. Piv txwv li, thaum WinCE hloov kho lub ntsiav, yuav muaj cov kev xaiv sib xws, suav nrog Wordpad, PDF, MediaPlay, thiab lwm yam. Yog tias peb xaiv, peb tuaj yeem pom cov khoom no hauv interface tom qab CE pib. Yog tias nws yog Windows operating system ntawm lub PC dhau los, feem ntau ntawm cov khoom yuav tsum tau rov nruab.
3. Hlawv lub software kernel los yog daim ntawv thov cov ntaub ntawv system thiab lwm yam rau hauv ROM nyob rau hauv lub embedded system hardware platform realizes ib tug tiag tiag "embedding".
