AICXC1A : Astronomical Instrumentation and Control with XC1A

<t>Version: 0.01<br/> Status: Under development<br/> License: GPL<br/> <br/> Modern telescopes use electronic sensors/detectors with various optical components in the light path. Based on the science goal the components could be changed under computer control. Traditionally this has been done with m...

Re: XCORE INDIA

Hi,

Anyone know how to get xmos boards in India? The one distributor listed on the xmos page didn't respond after an initial contact.

TIA,

Re: New XCore competition - have your say!

* I also think its important to allow software and not just hardware as it makes it easier for folks to get involved that don't yet have hardware by using the simulator for example. Al This would be nice. And for such contributions it would be nice to get some xmos hardware (dev kits?) to motivate ...

Re: XZPU - an XMOS based ZPU implementation

Sounds like a very nice project. We are currently trying the ZPU on a Spartan 3E board (from http://papilio.cc ). Planning to add more counter/timer modules into the ZPU. Waiting to get our hands on the xmos boards. Maybe a while though (govt purchase procedures...) All the best for your project. Sh...

Re: which xmos for image processing

Hi Al, Jonathan, Thanks for the detailed replies. Yes, the memory requirement would be a bottleneck. I think I could live with that 20MB/sec throughput for the transfer through the ports. This is for a polarimeter. There is a modulating half wave plate rotated by a stepper motor at about 5 to 10hz. ...

which xmos for image processing

Hi, Have been looking at the various options available from XMOS. I have an application wherein about 400 frames of 1024x1024 pixels 14bit size are recorded per second. The total run may last for several minutes. Obviously that requires a large amount of storage. My question is whether any of the xm...

I only see the following pic here : http://imageshack.us/img/blocked_login.jpg repeated for all the photos - not the real photos. Any idea why?

Re: Multi-Purpose Stepper Motor Driver

<t>Hi,<br/> <br/> This looks like a useful idea. Unfortunately, I too don't have any XMOS hardware to test out the code. I have one astronomical instrument that needs an 8phase stepper driver and also 4 or more 16 or 32bit counters (we currently use the venerable 8254 IC for this - it needs to count...
