(The core may have more direct access to relatively small amounts of memory (cache or registers), but that's a different issue.) The CPU also communicates with peripherals via buses. WebA floppy-disk controller (FDC) has evolved from a discrete set of components on one or more circuit boards to a special-purpose integrated circuit (IC or "chip") or a component …
