Why dont u draw an ASCII block diagram so things get clarified in ur mind as well for everyone else in the list?
I'm not good at all in drawing so let me try to explain in simple words. I have an NIC. From the NIC, I'll transfer data to the memory of an an FPGA based board. That board will then provide us with the processed data which will be then passed to a userspace application. The application after doing further processing passes it back to the kernel, then to the FPGA board and then again to the NIC. Two things are must: - The processing by FPGA based board - Further processing by some userspace application So, what do you think?
