PCI (Peripheral Component Interconnect) Express Slot
PCI Express architecture provides a high performance graphics infrastructure for
Embedded Platforms doubling the capability of existing AGP 8x designs with transfer
rates of 4.0 GB/s over a PCI Express x16 lane for graphics controllers
PCI (Peripheral Component Interconnect) Slot
The PCI slot supports LAN cards, SCSI cards, USB cards, and other add-on cards
that comply with PCI specifications. At 32 bits and 33 MHz, it yields a throughput rate
of 133 MBps.
PCI Interrupt Request Routing
The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines
over which devices can send interrupt signals to the microprocessor. The PCI IRQ pins
are typically connected to the PCI bus pins as follows:
32-bit PCI1
