(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)
