hi all,
We want to design a product using DSP processor.I want
suggestions for the processor available in market specifically TI's.
the gist of the project is as below..
this project is for medical industry.
a composite video stream either live or archived(usually of 5-8
minutes)is to be compressed.this is fed into a dsp processor which
has to process (involves compression) these images (we are now using
a video capture card at 30fps,704x576 PAL ) .after the compression is
done ,this data is then stored into a hard disk.
pls sugggest me the some processors specifically(TI processor,is the
TI's digital multimedia processor TMS320DSC24 well suited???) suited
for the above requirement.we wanted to use FPGA's but after reading
the above problems i feel,we dnt have more development time and
scarcity of guys in digital hardware.
thanks in advance :-)

Hello all,
I am in similar situation as the originator of this message. I graduated a
year or so ago and have taken DSP courses as part of my curriculum. I
enjoyed the subject matter of DSP & image processing greatly however the
labs were mostly done in MATLAB with minimal hardware integration. I now
have an image processing project I would like to develop and am
contemplating the hardware to use. this posting answered my questions on
FPGA's (thank you) . what I would like to know is the how the following
chips compare to FPGA in design and implementation and if they are worth
considering. Thanks for your help.

FPGAs aren't hard to change, depending on the FPGA. Compiling the algorithm
into something that will fit on a single chip can be hard if the wrong chip is
chosen. Troubleshooting can be hard unless a good emulator is used. With a
modern tool selt, FPGAs are reasonable easy. We use them a lot.

Thats what I meant... probably I should have used better words.... hardware
implementation would anyday be faster than software as far as performance is
concerned.
Moreover, if you need to change your implementation time and again, FPGA
could be a pain.

Hi Hemant,
I assume you mean faster to implement. It is certainly that. However,
you would have to make a terrible mess of the FPGA implementation for
it not to win handsomely in speed of execution.

Steve

The algorithms could likely be implemnted in the FPGA in a highly
parallel fashion, and would then be much faster than on a DSP.
If the DSP is fast enough, though, that should save you much in design
and implementation costs.
What algorithms and how fast does it need to run?

A processor would anyday be faster than an FPGA.

Hi All,
I am working on image compression algo,which needs to be finally
processor based.i need some suggestion regarding the time taken to
code,test the an image processsing algo in a standard DSP processor
such as TI's or in Xilinx FPGA.which one would be better???in terms of
time taken and performance..???
cheers
