I have a question on USRP E100.
The FPGA sends GPIO interrupts to Gumstix (OMAP) to notify that Data is
available for it to read.
How does the FPGA know that the OMAP system have finished
accessing(reading from) the GPMC CS , so that it can write to that
memory location again. What is the signaling mechanism used to prevent
FPGA from writing new samples while the DMA of OMAP is on the process of
copying the old samples?
