Concurrent Operation
The CPU in a PCI system runs concurrently with PCI bus mastering peripherals. Although bus mastering peripheral
devices are arbitrated, significant data transfer rate improvements can be achieved without splitting resource utilization
between the CPU and a bus mastering device. Peripheral devices can operate at speeds up to 33 MHz in a PCI
environment.
Burst Mode
The PCI specification also provides for burst mode of any length for both reads and writes.
Multiplexing
PCI is a multiplexed bus. Multiplexing allows more than one signal to be sent on the same electrical path. The
control mechanisms have been modified and extended to optimize I/O support.
Using PCI Adapter Cards
The American Megatrends Excalibur PCI motherboard has three PCI expansion slots. The PCI expansion slots can
accept any adapter card that complies with the PCI Revision 2.0 specification. P16 (Slot1), P17 (Slot2) are bus master
PCI slots. P18 (Slot3) is a slave-only PCI slot.
