Desperate to find the right FPGA board

Hi guys. First post to this newsgroup, let's pop the champagne ;)

I need your advice on selecting a FPGA module for my needs.

Anyway. I need to stream data from a PC to a device, and back. Around

For now this will have two applications : streaming many channels of high bandwidth audio (24/192), and instrumentation (DSO). More later.

I have a working prototype with the Atmark Techno Suzaku FPGA module. It handles the full 100 Mbps bandwidth (barely) but not in full duplex. However I do not want to use this module in the final design : it isn't really suited.

After experimenting with the Suzaku which has a MAC chip, and an Atmel NGW100 which has no FPGA but a decent CPU/MAC with smart DMA I have come to the following conclusions :

- I'd like to use the OpenCores MAC core to drive a PHY and DMA the data to a fast memory buffer.

- The FPGA will then forward the buffered data to the IO channels in due time

- I need a CPU, but it will not touch the data, only parse the packet headers (I use UDP which is nice for this application).

- CPU will also handle other stuff like LCD and GPIO

- Microblaze is OK

- No OS will be used

So, I'd need a FPGA module with the following :

- 100BaseT Ethernet PHY connected to FPGA

- FPGA with enough gates to instantiate OpenCores MAC core, Microblaze, some BRAM buffers, some FIR filters, etc.

- 1MB fast memory (SDRAM or SRAM) where I can put my buffers and also my executable code. More is also good !

- Should be small, and not radiate EMI like a radio station

- Max cost $200, cheaper is better obviously !

- It should work ;)

I'd like something like this :

But noone sells it apparently and where is the docs ? I dunno. I could also use a module with a hard CPU if there is a fast access (ie. bus) from CPU to FPGA. I know the Xilinx tools, but I am not a Xilinx fanatic...

So, what is your advice ? I'd rather buy a module instead of having to build it...
