I'm currently working on dsk6711 dsp board with code composer studio
2.0. I
would like to input image file into dsp board for image processing purpose.
are
there any efficeint way to do it?
sincerely,

The easiest and highest speed method is to write a MS VC++ program that
uses the Win32 API of the DSK. If you can get your 'video image'
into a 'memory image' format, the code to send it to the DSK is fairly
simple. Refer to DSK Help file and \ti\examples\dsk6711\board_util\
directory.

Dear All!<br>
<br>
I would like to use EDMA to write to McBSP on a 6711 DSK. Furthermore, I
would
like the frame sync pulse to be present only when data is being transferred,
I
don't want a continuous frame sync. <br>
I can set up McBsp to operate in this mode and everything is OK when
<br>
I write to McBSP from the CPU, but as soon as I write using EDMA, <br>
the frame sync signal becomes continuous! And it stays so until I reset the
board.<br>
<br>
If anybody knows the solution, please tell me.<br>
<br>

Hi
You can check FPER which and the receive and transmitt control
registers values where frame width goes low it means the start of
receiveng/transmitting the data bits but similarly when u set appropriate bits
in FPER which is nothing but the period at which data transfer can take place
,then u check out the index and counter values in EDMA and set
appropriately u may avoid the continueous transmission.Also use XEVT,REVT
instead of XINT,RINT so that u can reduce the traffic at the bus.
hope this work out

Maybe I did not state it correctly - there is no continuous transmission (DX
is
inactive), but the FRAME SYNC becomes continuous,
although I want it to appear only together with the data bits.

Hi!
DX is in active may be bcos u dont have data bits to transmitt from EDMA to
DXR
registers like which u want(i think u are doing this properly) but when u
come
to FSR where period and width of frame synchronisation signals u are not
matching with how many bits u want to transmitt/receive from EDMA ,if u can
give
me code i may look into that ,but bfor that u verify all the things for the
data
transmission(in RCR,XCR registers are properly configured.and one thing in
which
mode u r doing this in master/slave(SPi) or normal communication....?
hope something may help u!

Hi Mike,
I am also developing MPEG 4 Simple Profile Video Encoder/Decoder
(concurrent implementation) on TMS320C67x using DSKC6711. Could I use the method
below for testing the encoder and what should I do to test the decoder
?
I would be deeply obliged if you can help me.
Regards,
Nalin Pithwa

It is sometimes difficult to give "the best answers" to questions.
Sometimes it is a student needing to prove that a simple project works - in
which case loading an image into an input buffer, and then processing it to an
output buffer is all that is required. Since the message lacked any
concrete technical information, this was the scenario that I answered.
If you are trying to do some "real image processing", then I would
agree with Jeff that TI's IDK card would be the way to go.
