Hi Eddie,

I saw your message on comp.dsp. I am myself just started learning DSP
too, and have just bought TI C6713 DSK. As I have some knowledge in
video coding like H.263, MPEG4, I will be really interested in joining
you to develop the H.264 coding in DSP, to get more experience in DSP
DSK. Can you tell me more about the project you plan to do ?

Thanks. Hear from you soon.

Regards,
Arthur.

If this is a hobby project, you might want to focus on the techniques
and applications of DSP in general, before you start implementing
low-level algorithms on a certain DSP processor.

You would only need a C compuler and some plotting software to
get started. Having access to matlab or something similar (octave
scilab,...), would ease things considerably.

I would choose one of AD's EZ-kits...like SHARC ADSP-21364. The only 
drawback is the documentation and
support (I think TI's is better), but when it comes to programming it's 
pretty straight-forward.

Hi Eddie,

There are a lot of video platforms based on the TI 64x series
(especially the TMS320DM642), so you couldn't go wrong there. In
addition, it has video port peripherals that are designed to interface
with standard NTSC/PAL encoders/decoder chips (e.g., the Phillips
7115).

That said, in my opinion, you're biting off way more than a beginner
can chew. Entire companies are built on implementing codecs like H.264
(e.g., Ingenient). Even if you forget the DSP theory involved, the
DM642 and its ilk are extremely complex chips.  I've used the DM642
and found it to be an extremely complex chip to use and I've been
doing it for 30 years (well, embedded systems at least, DSP for the
last 15 years or so).

As a beginner, it would be more appropriate to implement something
like a digital filter on a EVM board, say, one based on the 55x
series.

"DSP" itself isn't processor specific -- it's a specialized branch of 
mathematics that lends itself to software solutions.

As far as the specific processor goes, as long as it has enough 
bandwidth it'll do.  I'd look for the one that has the best support and 
tools.  If it's just for learning you may want to choose the Pentium 
that you probably used to write your post, at least initially.  Once you 
understand the algorithmic parts, then consider which processor you want 
to migrate to.

Dear all,
    I want to learn DSP, but I don't know which DSP  i should choose.
TI TMS67xx or ADI blackfin or OMAP or others?
My target is to implement the h.264 standard in it.
Which DSP could satisfy this target?
Could anyone  give me suggestion?
Thanks a lot.

BR,
Eddie Chou
