(Devices) What is PCI?
Back
PCI = Peripheral Component Interconnect

It’s a standard to connect devices s.t. communication between software and I/O hardware is possible.

Deals with:
  • Finding out which devices are in the system
  • Which addresses should each device’s registers appear at?
  • Which interrupt signals from the device should map to which exception vectors?
  • PCI allows Bus Mastering (devices no longer need a DMA controller)
