Süsteemikiip (inglise keeles system-on-a-chip, system on chip ehk SoC või SOC) tähendab elektroonikas kiipi, millesse on integreeritud kogu elektroonikasüsteem (näiteks arvuti).


Süsteemikiip võib sisaldada protsessorit ja mälu ning lisaks käskude töötlemiseks vajalikele riistvarakomponentidele ka arvuti tööks vajalikku lisaelektroonikat. Tüüpiliseks rakenduseks on sardsüsteemid, aga süsteemikiipe kasutatakse veel digitaalkaamerates, mobiiltelefonides, nanotehnoloogias, meditsiinis kasutatavas tehnoloogias ja mujalgi.[1] Definitsiooni järgi võib esineda ka muid süsteemikiipe, mis ei sisalda protsessorit. Arvuti süsteemikiibi kohta võidakse kasutada ka mõistet "mikrokontroller".

Komponendid |


Sardsüsteemide süsteemikiibid koosnevad tüüpiliselt näiteks järgmistest komponentidest: [2]



  • operatsioonisüsteem;


  • rakendustarkvara;


  • pingeregulaatorid ja toitehaldusahelad;

  • ajastusvahendid, nagu näiteks faasilukustusahelate kontrollsüsteemid või ostsillaatorid;


  • protsessor või digitaalsignaaliprotsessor;

  • välisseadmed, nagu näiteks reaalajalised kellad ja loendurkellad;

  • välisliidesed, nagu näiteks USB, FireWire, Ethernet, UART (universaalne asünkroontransiiver) või SPI siin;

  • analoogliidesed, näiteks analoog-digitaalmuundurid ja digitaal-analoogmuundurid;


  • muutmälu (RAM) ja püsimälu (ROM)


Eelised |


Süsteemikiibi kasutamise kasuks räägivad järgnevad positiivsed küljed: [3]


  • suurem sooritusvõime, kuna kõik ahelad on ühel kiibil;

  • väiksem ruumivajadus;

  • väiksemad nõuded mälu järele;

  • suurem süsteemi töökindlus;

  • madalamad tarbijakulud.


Piirangud |


Süsteemikiibi kasutamisel tuleb arvestada järgnevate kitsaskohtadega: [3]


  • suuremad kavandamisvajadused;

  • suuremad kulud süsteemi disainile ja prototüüpimisele;

  • pikemad disaini- ja prototüüpimistsüklid;

  • keerukam silumine;

  • madalam mikrokiipide tootlus ja kõrgemad kulud pooljuhtplaatidele.
