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 FPGA! 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 appologize for emailing on this forum, but there are a ton of smart and helpful people here so I thought I would ask.. 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. Thanks!
