I have an application wheremMy FPGA will be Generating Data which needs to be transferred to the PC. The Data is a real-time stream and is so large (512MB) that it all can’t be buffered and sent. What I want is a simple USB interface where my state machine can write data (32-bit) to the PC on a sample by sample basis (1Mega Sample / Sec) rate. It would be desireable on the PC end where I to have to do little driver development. I just want to read the stream data and dump to a file (c++). I can write the C code but have no experience with USB interface stuff. Ideally what I need is something like the FTDI 245 Chip, just faster! The USB interface just looks like a FIFO and I just read and write data from the FIFO
My current FPGA code can fit in the Spartan 3 device, I just want to see if my application is possible with your modules. If needed, small buffers can be created from the data stream (1k chunks for example). I just need to be able to stream the data in real time. I also need a simple mechanism for writing to the FPGA to inidicate the start of a stream.
Is this application possible with your module?
Thanks in Advance,
