I think the newest version of the compiler (rev 4.0 that came with Code
Composer Studio 1.20) can software pipeline nested loops. Are you using the
newest tools?

Hi, there,
As a new comer in this field, I am bothered by a
question. It may be simple to you. If I want to learn
something about TI DSP, especially C6x, what documents
should I read? --It seems impossible to read all the
stuff since they are in huge packs. Suppose I've got a
starter kit, I want to grasp the DSP coding language,
and want to use it for some kind of algorithm
implementation. Where should I begin, and what
procedures should I take, to be familiar with the
programming as soon as possible?
can someone there figure out a algorithm, a
protocol or some kind of thing that could be easily
put into implementation, i mean, to be programmed into
the code. It should not be too easy to work out in an
hour, and not to be too hard to be implemented. The
one
which needs a month's work is most desirable. I think
it a good way to learn something in the process of
using it to solve problems, right?
Can anyone help me with that?
Thanks in advance and looking for your reply,
badly. __________________________________________________

Hi,

Since my project needs multiple analog I/Os,
I'm looking for a daughter board providing 2-channel 16 bit
A/D and D/A I/Os with 44 KHz sampling.

I just want to connect it from 6211DSK via
80-pin daughter board connector and hope it is very
easy to use :-P
I would be happy if the board works immediately after
installation.
I mean, I would like to skip special extra-configuration (e.g., FPGA
programming...)

Thank you in advance.

i warket it
but there was a error
i cant solve this problem
what must i do

Hello,

I'm trying to interface a TMS320C6211
DSK-Board in order to transfer data
from the DSK-Memory to a Linux PC. I
cant find any information in the
manuals or the general help how to send
data from the DSP to the Parport. The
only hint I found was that the DSP-HPI
is connected via a special chip called
PPC to the port. Can any one help me ?

Werner

The parallel port on the DSK is only used for the emulation control via code
composer studio. I think the HPI port is available at the daughtercard
interface, or you could use the McBSP to the serial port. Either way you
will still need to control the DSK from Code Composer which is a Windows
application.

Hi

I'm developing a JPEG compressor using the C6711 chip. According to TI
documentation, i should be running at around 69 frames / sec. I can only
reach around 35 frames / sec. Does anyone know how to efficiently move data
from external ram to internal ram for processing ??

Thanks

Hello:
       When I ran my program for several times circularly, two wrong messages occured, that is "
      Trouble running Target CPU: Illegal opcode (65737561) at pc = 0x80004488 Illegal opcode at pc = 0x80004488
      Can't Run Target CPU: SIM may not be in stable state, Advisable to correct the error before Running.
      Can anyone told me the possible reason and how to solve the problem?
      Thank you!

How do I program a PCI to communicate between two C67x processors on a board, which has an on-board PCI bus connecting them ?
 
Thanks
