We're seeking to get maximum throughput from USRP E100. Our goal is to
collect some samples to RAM and then process them offline. Right now
E100 can't achieve even 4MSPS, which is not enough for us. What is
your feeling what is the limiting element? GPMC should be wide enough
to transfer much more data and RAM should be fast enough too. Is it
IRQ, or user-space processing?

We consider replacing Gumstix with a more powerful C6-Integra SoC,
like TMS320C6A8167. But before we dive into hardware modswe want to
make it somehow working with what we have already. :)

This is for the open-source WiMAX scanner project:
