VxWorks To XPE

[Andy Izsak]

Hi,.

My company is looking to migrate from WindRiver's VxWorks to XPe.

Our products are a network of 10 to 30 systems running on 100bt full duplex
switched network and delivers 1/30 sec response from control (knobs) to
process (DSP) and feedback (Display) system wide.

I'm looking for references of other companies and or projects that had
multiple nodes, high availability and real time performance.

I would think there are many process control apps that are similar to ours.

Any help would be greatly appreciated!

Andy,

I saw your reply in other post, but I still fail to see what answer you
expect to hear.

I'm doing all "real time" control from my driver.
Live video acquisition, video content resizing and multi monitor display of
live video from up to 24 video sources, gigabit network delivery, etc.
From user mode we use compression user interfaces, slow network support,
telemetry, etc.
Since everything is interrupt/event driven, time or windows time slice is
not important at long as everything in driver is handled in 20 ms. Video
capture goes by rate of 50 fields per camera.

If you use network as only mean for input and output, you could handle
communication at NDIS level, so you would be event driven (you would have
fastest response that is possible).

Regards,
Slobodan
