Ib qhov system ntawm ib lub module (SOM) yog ib lub rooj tsav xwm hauv theem siab uas sib koom ua ke muaj kev ua haujlwm hauv ib tus qauv. Nws muaj peev xwm muab cov zauv digital thiab analog tso rau ntawm ib lub rooj saib xyuas nkaus xwb. Ib daim ntawv thov raug nyob hauv thaj chaw ntawm lub tshuab kos. Tsis zoo li lub tshuab computer ib leeg, ib qhov SOM ua haujlwm pabcuam tshwjxeeb zoo li lub system ntawm lub chip (SoC). Cov cuab yeej ua ke hauv kev SOM feem ntau yuav tsum muaj theem siab ntawm kev sib txuas rau cov laj thawj xws li kev khiav ceev, sij hawm, lub npav dav thiab lwm yam., Hauv ib qho kev sib xyaw ua ke. Muaj cov txiaj ntsig hauv kev tsim kom muaj SOM, xws li SoC; Ib qho tseem ceeb tshwm sim yog kom txo tus nqi ntawm lub rooj tsavxwm los yog lub ntsiab PCB. Ob qho kev ua tau zoo ntawm SOMs yog tsim-siv dua thiab tias lawv tuaj yeem ua ke hauv ntau cov kev siv computer.


Keeb kwm

Qhov kev sau npe ntawm SOM no nws muaj cov hauv paus hniav nyob rau hauv cov tshuab ua raws li. Nyob rau hauv nruab nrab xyoo 1980s, thaum VMEbus cov hniav siv mezzanine modules, [1] no feem ntau hu ua System on a Module (SOM). Cov SOMs tau ua haujlwm tshwj xeeb xws li lej kev ua haujlwm thiab cov ntaub ntawv ntiav. Cov SOMs tau thiab tseem siv ntau yam xws li SUN Microsystems, Motorola, Xerox, DEC, thiab IBM hauv lawv cov tshuab hlwb hlau.


Tsim

Ib qho raug SOM muaj xws li:


tsawg kawg yog ib lub microcontroller, microprocessor lossis digital teeb liab processor (DSP) core

Multipessor systems-on-chip (MPSoCs) muaj ntau tshaj ib tus tub ntxhais ua haujlwm

cov cim xeeb cim xeeb xws li xaiv ROM, RAM, EEPROM thiab / los yog flash nco

lub sijhawm qhov chaw

kev lag luam tus qauv kev sib txuas lus xws li USB, FireWire, Ethernet, USART, SPI, I²C

peripherals nrog rau cov counter-timers, real-time timers thiab lub zog-rau pib dua generators

analog interfaces nrog ADCs thiab DACs

voltage regulators thiab hwj chim tswj circuits

Daim ntaub ntawv

Blade servers

Cia cov hniav

Kev kho mob

Cov ntaub ntawv tshaaj tau

Network khoom siv

Internet yam

Ntug tshuab
