I updated the wiki paged and added state machines.
(http://gnuradio.org/trac/wiki/UsrpTxModifications)
Here are the issues still unresolved that I am aware of:
- Are the overrun/underrun flag per channel or global? From which fifo
should they be generated?
- When a packet is outdated I still have to walk though it to empty to
skip it. This can be resolved by using a RAM block rather than a fifo
for the N chanX_fifo be will require more coordination between the USB
block and the data block.
- Now I am assuming that the samples are 16bits interleaved, how will
the sample format chosen by the user be reported to the FPGA?
