Synchronous, 32-bit, 33MHz PCI-to-PCI Bridge for Video Capture Applications

Industry’s First and Only PCI-to-PCI Bridge that Supports up

to Ten PCI Devices

Total System Cost Savings

The PLX FastLane PCI 6156 reduces total system cost for OEM developers

because rather than needing two cards to support a large number of camera

feeds, only one card is needed. As an example, the typical PCI-to-PCI Bridge

supports four PCI loads. In order to support 8-10 cameras, at least two or

perhaps three, different cards need to be installed in order to address the load

requirements and stay within the PCI load tolerance. But with the FastLane

PCI 6156, only one card is required to support all ten cameras, thus reducing

the overall system add-in card cost by 50%-66%!

The additional cameras on a single card also provides for more system

efficiency. Since the PCI 6156 allows more cameras to be supported on a

single card, more cameras can be accommodated per system. Most surveillance

systems have six slots per system. Each slot can now host, rather than four

cameras, up to ten cameras each. This provides an increased system efficiency

of 40%. This efficiency equates to an overall reduced system cost, as only one,

rather than multiple, surveillance systems are required to support up to 60

cameras.

Performance

The PLX FastLane PCI 6156 offers increased PCI

throughput performance. The PCI 6156 optimizes

performance with “no retry penalty” flow and

uninterrupted zero wait state bursts (for up to

1KB packets). The no retry penalty flow

feature prohibits a requesting device from

being held off from the bus, and “re-tried”

while the PCI Bridge pursues the request

on the secondary bus. A typical retry

policy results in increased overall latency,

as the requesting device will have to continue to retry

the bus, wait until it gains access to the bus, and then subsequently get the data,

once the data is available.

The PLX FastLane™ PCI 6156 PCI-to-PCI

Bridge is a 32-bit, 33MHz device capable of

supporting up to ten PCI devices. Targeted at the

video capture and surveillance add-in card

markets, the PCI 6156 brings unprecedented bridging, through support of the

greatest number of PCI loads, as well as cost savings and increased

performance, to OEM systems.
