Experimental Physics and Industrial Control System
|
I recently got a GigE camera from Prosilica. It
is 1360x1024 resolution. At 8-bits the StreamPix software from Norpix is
able to acheive frame rates of 30Hz at full resolution, and 52 Hz when it is 2x2
binned to 680x512. This is under Windows, using the single GigE port on
the PC, with the camera and PC connected directly to a GigE
switch (which also is connected to the rest of the LAN).

Sorry for not being more clear: I am only interested in
the EPICS and EDM applications you've created for displaying the video,
not in any of the RTEMS-related code. I did
not change any EDM applications or EPICS base. The protocol is
CA. The optimization is implemented at RTEMS
device driver and IIDC1394 library layers. The BSP is
RTEMS-MVME5500. The driver does not have to be linked to EPICS. It is
just another real-time application with the RTEMS-MVME5500 BSP. It
triggers the camera at 30
fps and display at
30Hz simultaneously for the 1024x768x8bit mode (video mode) even under the limited 100MHz
network bandwidth and
indeterministic network environment. Yes, in the 100MHz NIC, the
actual network throughput is not 30Hzx1024x768x8 bits. But it is greater
than 10Hz. Thus, the system does not have to run in a private
network. I do not believe it will be
slower with a non-EPICS application.
Here at the CLS we're using linux-based soft IOCs to
communicate with Flea and Flea2 cameras.
We're having difficulty in achieving video frame rates
greater than about 10 Hz at 640x480 resolution. I'm interested to know how
you are getting such fine performance (aside from using RTEMS :-)
).
Perhaps I will have the
optimization written in a publication, so that hopefully it can help the
Linux or vxWorks users. If so, will you feedback to this list
regarding how much improvement you achieved in the Linux driver
?
