Hi!

I am using DEC's XMedia Audio Developer's Tools.  I wonder if there 
is a news group for XMedia, or if there are people also working
on it?

Any information will be greatly appreciated.

There is a group biz.dec.xmedia.  You're welcome to post your comments
there or here.  I'm sure many people are interested in your experiences.

Frame Grabbers <-> PC RAM

Hi, I hope this is the appropriate news group for the following discussion. I 
have a question regarding image transfer from frame grabbers to PC RAM. I am 
interested in capturing a 1k x 1k x 8 (1 MB) image from a CCD using a frame 
grabber. At what rate can I dump these images from the frame grabber on to the 
PC RAM or possibly a SCSI hard disk. If the CCD operated at 5Hz frame rate, is 
it possible to transfer all 5 MB to the RAM in a second? I have been told data 
transfer is limited by the PC bus. Is this true? How about with a DMA transfer?
If the answer depends on the system, what are the typical transfer rates for
a 486 50 MHz PC with 64 MB RAM and 1 GB SCSI HD.

Any help is appreciated. Thanks. By the way, if this would be more appropriate
for another group let me know. I cross posted this on sci.image.processing.
