Apologies for the continuation of the off-topic thread, but anyway:

In my application I use an AVR with an Altera FPGA to control some ADCs,
and do other stuff. The ADC result is memory-mapped on the external bus
of the AVR, which works well. The FPGA also performs many other
functions, which are easily memory-mapped into the AVR's address space.

I use the internal SRAM of the FPGA for my ADC, but it can be used for
scratch/heap ram of the AVR (trying to keep roughly on-topic...).

I chose Altera because the tools are free (not libre), but Xilinx tools
are also free (but not libre), so there is no advantage to either.

I recommend you look at the two manufacturers web sites, and decide on a
device, then download the tools etc.

The silicon is very cheap for what you get, but pay attention to the
configuration method; some configuration chips are 5x the price of the

If you need more info, feel free to email me off-list (although I won't
be able to reply for a couple of days as I'll be out of the office).

I've realized that I'm not going to be able to accomplish one of my
projects using an AVR.  I appologize for emailing on this forum, but
there are a ton of smart and helpful people here so I thought I would

I'm looking at using an FPGA, and have never used one.  I was wondering
what a good brand would be - a good dev/learning kit might be - and
ideally something that I can run or program from linux and using fairly
inexpensive hardware to program.  I'm thinking of Xilinks (sp?) as that
brand keeps popping in my head but I've not got a clue as where to
start.  Any pointers would be greatly appreciated.
