Basic FastVision
Framegrabber
Alacron introduces its newest high-performance framegrabber board
– Basic FastVision. The Basic FastVision is for OEMs and End
Users who anticipate a demand for diverse I/O requirements and higher
bandwidth. The Basic FastVision is a full-length PCI board
with up to two Camera Link inputs, each buffered with 64-128 MB
of dedicated high-speed (528 MB/sec) SDRAM. The Camera Link
inputs and 64 bits of I/O provide the basis for high-speed communication
with any Camera Link datasource. Applications include digital
communications, medical imaging, semiconductor wafer and mask inspection,
radar and sonar signal processing.

Basic FastVision Features
- Single slot PCI board for data capture
- Two 85MHz bi-directional Camera
Link ports for packet switched inter-card
transfers at 2.38 Gbits/sec per port
- 64 to 128 MB of distributed SDRAM per Camera Link port
- Two PMC connections provide support for two 32 or 64 bit (33MHz)
PMC modules and support a 320 MB/s Fast Channel interface
- 33 or 66MHz, 64 or 32 bit primary PCI bus interface with a (non-transparent)
bridge to local PCI bus
- OS support: Linux and WindowsNT
- Fast Channel:
- 80 MHz 32 bit persistent channels in 4 bit increments for
intra- and interboard communication
- Point to point connections at up to 320 MB/s via cross bar
interconnect
- Data traffic does not affect host CPU or PCI bus
