Hi,
i am working with a ep9302 micro (cirrus edb9302 board, where i
mounted a Linux embedded 2.6 kernel.) and it is very important for me
to know if this board can menage data transfer of 4 Mbit/s.
My target is to adquire from a tipical digital video source (for
example satellite) a mpeg2 signal (transport stream format) and then
do the incapsulation of this stream in a LAN.
Every test i did showed me that it can easily menage a 1 Mbit/s
bitrate (tipically from a file source) but when i try to adquire the
signal from satellite (4 ore 5 Mbit/s) the system crashes. It seems
that the board cannot read and demux such a quantity of data even if
i am using the DMA (so that the stream is directly available in the
SDRAM nearly without cpu menagement).

Anyone did some test on it?

Any help you can give me would be greatly appreciated.
