Need some advice on tools/processor

Started by dmcmicro April 25, 2005


I wanted to solicit some advice from, what is most certainly, a AD
experienced audience regarding development tools and future processor
selection. These question may seem naive to the experience; I am
working up the learning curve. That is, I have DSP theory in my
history (with cob-webs); I am clearly not an accomplished HW DSP
developer.

I am reintroducing myself to the 21xx series (2181 and 2185) using
the old (1990's vintage) DOS / Win3.1 tools. The intent is to ramp up
to speed on a software defined radio project called the DSP-10 (HAM
radio project). I can get by writing assembly using
asm21/ld21/sim2181 (using DOSBox) for now but am anticipating my
1yr/5year goals in SDR.

So, what I was hoping I could get advice on is:

1) Is VisualDSP worth it with respect to the 21xx?
2) If I purchased VisualDSP can it be use cross processor
(I.e.Sharc/Blackfin) or is it a new purchase per processor?
3) Does anyone have advice for the next processor keeping in mind
my SDR interests. Blackfin looks interesting especially considering
uCLinux? Clearly, I am going through the learning process. As such
Fixed point seems fine, but is Blackfin suited for SDR?
4) Is everyone paying full price for VisualDSP or is AD open to
reduced prices for Nuts-and-volts type?

Thanks in advance,

Dave

It is a separate purchase for each family. You definitely want to
select the family you will be working with before purchasing anything.

I would definitely recommend something in the SHARC, TIGER SHARC, or
Blackfin for SDR. What DSP was used in the DSP-10?

There are a number of vendors who watch this list who might have
"Nuts-and-volts" packages available. Hopefully they will chime in. >Thanks in advance,

Check out www.BeastRider.com for SHARC only. It's the only Nuts-and-volts
package out there. However, you usually can get ez-kits with built in
usb debuggers and that should work for you.

What are the limitations to the VDSP package that comes with the ez-kit? >Mike Rosing

Based on Steve's suggestion, I looked back through my archives. I was
able to find and install a "VisualDSP for the EZ-Kit Release 6" and
disovered that it include only the debugger. So, it's not much, but
it's seems as if it's a step up from the DOS-based debugger running on
XP in a DOSBox window. As I recall, that was a download from the AD
site in 1998. Not sure this will help anyone, but what the hey?

Code size is limited to fit in the allocated C space. If you add external
ram it won't allow you to access it via the architecture file. You can
not eliminate sections (and I don't know if you can even re-size them).

There are work arounds, but it is not as clean as a full linker will
allow. If you can get your application to fit in their defined spaces, it
is a low cost way to go.

Patience, persistence, truth,

Wouldn't it VisualDSP++ 3.5 work for your needs? It
works for me on both Win98 and WinXP

Sure:

http://www.analog.com/processors/resources/crosscore/toolsUpgrades.html

Go to the end of the page, of if need it for another
family rather than ADSP-21xx, go to the "archives"
links.

I forgot about that. I thought you could only get 3.5 for the 2xxx series?
