Any practical DSP app notes for TI?

Hello All,

TI's web site is, for the most part, pretty good. However, I find their 
DSP section shallow and horrible. Lots of glitz and fluff, not nearly as 
much "meat" as on their MSP430 section. Worst is when the site starts 
some stupid applet that brings it to a crawl. IOW, quite useless to me.

What I am looking for: Info about what size (and cost...) DSP can do how 
much in terms of running an FFT and other stuff. Pretty much like an app 
note. What is the best source for that? Doesn't have to be TI although 
their 5000 series DSP seem to be favorable since they come in varieties 
under $4 a pop.

There is *lots* of information, technical specs, application notes, etc., 
in their DSP village web site:

DCMP=TIHomeTracking&HQS=Other+OT+home_p_dsp

Here's a (free) DSP library for the C55x:

You'll have to navigate a bit around the site, but I'm sure you'll find 
what you're looking for.

HTH,
George

That's the one I had tried. The second it begins to load 
"ehg.ti-hitbox.com" the browsers (several) on several PCs slow to a 
crawl and after a while a warning comes up that an applet is slowing 
down the browser. The only way out so far was to right click the 
browser, shut it down and re-open it. Why can't they keep it simple like 
with the MSP section?

The only other site where that happens is Philips which is why I stopped 
designing in their parts. With them it seems that is because some 
corporate whiz kid thought that every engineer needs to see their stock 
quote all the time.

Thanks! That is going to be really helpful. AD has something like that 
as well but their DSP prices are too high for most of my projects. Wish 
they had kept ye olde 2105. That one was very cheap, even back in the 
early 90's.

Why not direct that comment to the Philips Webmaster ?

[ Seems to miss the stock quote :) ]

Then, they can fix the website, and you can use their parts again....

Been there, done that. I even wrote the top brass of some companies 
(including Philips). No answer. Oh well, at least I can say that I 
tried. Overall I've pretty much had it with many of the EU semi 
companies anyway. The last bout with one was a few weeks ago when it 
took more than a dozen wake up calls to get samples. Well, at some point 
after I climbed up the hierarchy apologies were made and samples were 
promised. They never came and one of my clients was a bit miffed.

Why is it that National, TI, etc. are so much more efficient? Not just 
in web site design, also in responsiveness to the customer. At least in 
my design practice it has paid off handsomely for them.

Ti have lots of docs, just need to look at the actual processors

What about Anlog Blackfin ?
One of the BF531's?

Yes, but many are following a trend that you also see in uC: 
"Interfacing the xxx to yyy". Not much meat there.

Even in the analog world (my domain) it's going that way. Guess the old 
hands with those great circuit ideas have retired, so I kept all their 
application books.

That is a good DSP. Around $5 which kind of fits the bill and it also is 
less of a power hog (if operated under 100MHz). But no ADC :-(

Separate ADCs wouldn't be a big deal but the ideal situation is to have 
the whole system on one chip, on the DSP.

  Today, I got the same annoying stall-on-Stock-price nonsense, so
I also lobbed a scud their way, and started my 'will they fix it?'
timer...

They won't fix it. Sometimes I wish I was the CEO of one of those EU 
companies for just one month. I bet it would take less than a month to 
teach them how to increase their sales, big time. All that upper mgmt in 
Sales&Marketing has to do is copy what TI, National, AD and others have 
always been doing. Those who wouldn't want to, I'd fire.

Then I'd want a commission of 1/10th of a penny for each extra Dollar in 
sales. After that I'd buy an island, a LearJet and some other 
necessities and retire.
