PCI/ PCI Express-Communication User Manual 2

1.1 Description

1.1.1 PCI Bus

The PCI Bus is a high-performance bus that provides a processor-independent data

path between the CPU and high-speed peripherals. PCI is a robust inter-connect

mechanism designed specifically to accommodate multiple high performance periph-

erals for series communication, SCSI, LAN, etc.

Advantech serial communication card leverages the “Plug and Play” capability

defined in the PCI 2.1/2.2 bus specification. The board requires only one PCI slot

within the personal computer and provides independent serial channels. All channels

are addressed in a continuous 32 byte I/O block for simplified software access. And,

all channels may also share one PCI interrupt. An interrupt status register is available

for determining the interrupt source.

The Advantech PCI communication card comes standard, containing deeper FIFOs

than serial port. These upgraded FIFOs greatly reduce CPU overhead and are an

ideal choice for heavy multitasking environments.

1.1.2 PCI Express Bus

The PCI Express Bus is a high-speed, scalable I/O serial bus technology that is stan-

dard designed to replace earlier PCI bus. Thus, PCI Express has numerous improve-

ments such as higher maximum system bus throughput, less I/O pin, more detailed

error detection and reporting mechanism, and smaller physical footprint. Although, at

the hardware level, PCI slots and PCIe slots are not interchangeable, at the software

level, PCI Express preserves compatibility with PCI device drivers and OS.

PCI Express is a point-to-point connection, which means it does not share bandwidth

but communicates directly with devices via a switch that directs data flow. By adding

more lanes, scalable features can be achieved for greater bandwidth.

The PCIe link between PC and other devices can consist of 1 to 32 lanes. These

numbers indicate the number of lanes you wish to have. For example, PCIe x16 has

16 lanes.
