Application:
Medical Imaging System
PLX Product:
PCI 6150 – 32-bit FastLane PCI Bridge
Key Benefit:
Consolidates Multi-Rate Bus Signals Using
Asynchronous Bridging
PCI-Based Medical Imaging Systems Use Multiple
Bus Rate Signals
Medical imaging systems combine high-speed
imaging signals and low-speed system control
signals in the same system. For example, the
are placed on the main bus, then the 66MHz signals
will be forced to”fall back” to 25MHz, thereby
downgrading system performance. A PCI bus will always run at the
speed of the slowest device attached to the bus.
The PCI 6150 Bridges from 25MHz thru 66MHz
The traditional Intel PCI-to-PCI bridges do not have asynchronous
bridging, and hence are not able to address this application.
The solution is an asynchronous FastLane
6150 allows 25MHz control plane signals to connect to the
same system bus as the 66MHz imaging signals without dragging the
bus (and hence system performance) down to the lower frequency
range.
