Yleinen koostumus

Suuremmasta näkökulmasta SOCsisältää:

1.Logiikkaytimet sisältävät suorittimen, kellopiirit, ajastimet, keskeytysohjaimet, sarja- ja rinnakkaisliitännät, muut oheislaitteet, I/Oportit ja liimauksen eri IP-ytimien välillä jne.;

2.Muistin ydin sisältää monenlaisia ​​haihtuvia, haihtumattomia ja välimuistit;

3.Analoginen ydinsisältää ADC:n, DAC:n, PLL:n jajotain nopeita piirejä, joita käytetään Analogisessa piirissä.
