Very good point.  If you wanted to use one of these for 
prototyping it would probably be a _lot_ less expensive 
overpopulating the memory by a factor of four than it would 
be to buy the unencumbered tools.  Do I understand correctly 
that the limitation is to 1/4 of whatever amount of program 
memory is installed, that you can increase that with this 
kit, and that that is the only limit placed on the software?

Al,

And (I suppose), if you already have a full license, you can take full 
advantage of it, no need to install restricted licenses... Am I right?

As for the FPGA toolset, I'd like tou to clarify something to me: the Web 
Edition of Quartus (from Altera) is free, but only functional for 150 days. 
What happens nect? Someone at comp.arch.fpga mentioned that simply asking 
for a web edition license works just fine, and that it takes just one day, 
two at most. Is that true? Would I need to reinstall the tools? Would I need 
to format the hard drive where it is installed, in order to clean up 
registry entries? Somewhere (maybe comp.dsp?) I read that for example, If 
you want to reinstall a Test Drive (which means: evaluation) version of 
VisualDSP++ on the same computer, you'd had to reformat your hard drive, 
because any newer installation will recognize that a previous installation 
expired. Is it the same as with Altera?

The license restrictions are exactly the same as an EZ-Kit. The SHARC has 
a fairly large memory. You may find that your programs don't grow large 
enough to matter. If you are building large projects, I would speculate 
that your total costs are significantly higher than the tools cost. ADI 
does not charge for upgrades either. VDSP 1.0 customers can update to 
VDSP 4.0 for free.

I know that tool costs are a significant burden to small guys. My wife 
and I own all the shares in Danville, so every tool purchase I make is 
"real" money to me as well.

Oops.  Not so good.  Terrible, in fact.  The cost of the 
unencumbered SW is absolutely prohibitive without corporate 
deep pockets and 1/4 memory is not a viable solution for the 
long term.  Ah, well, it does say "evaluation", not 
"development."

Thanks,

I guess they got moved again. We'll fix this tomorrow.

The board comes with VisualDSP++ Ver 4.0. The version we ship includes an 
EZ-Kit License. An EZ-Kit License works like a full version with no 
restrictions for 90 Days after which it limits you to a maximum program 
size of 1/4 the memory. From a VDSP point of view, our cards look like a 
EZ-Kit.

I am very pleased to announce that we just got a license from ADI to use 
the EZ-Kit debugger on our dspstak SHARC based boards. This means that 
our boards work just like an EZ-Kit. We currently can support the ADSP-
21261, ADSP-21262 & ADSP-21364. You can use VisualDSP with the same 
restrictions that any other EZ-Kit has.

The Altera Tools are Quartus II Web Edition and an Altera ByteBlaster. 

You can download the user manuals from our web site to get more details.

You can buy the whole kit from Arrow for $199. This is a special 
promotional price that is limited to one per customer. Details are also 
on our web site.

Al, I found that these links there are broken:

 
http://www.analog.com/processors/processors/sharc/technicalLibrary/manuals/2126x_core.html
http://www.analog.com/processors/processors/sharc/technicalLibrary/manuals/2126x_peripheral.html

Is there information (I couldn't find any at your site) on 
the Altera and Analog Devices software tools that come with 
the eval board?


Thanks,

Bob

Hi Tony,
I think that you are less of a novice than myself!  I'll start by being
honest and saying that I am going to upsample just because everyone
else does it.  Of course I am not under the impression that upsampling
adds any new information to the audio signal.

I THINK that upsampling is done because with more resolution in that
data, any rounding errors in calculations are less significant.  Also,
the upsampled data stream can be converted back to Analog with a much
simpler LPF.

It looks like I'll order the Danville kit.  It is just in my price
range and seems to pack alot in.

Before you go too far down that path, you might want to check out
this project:
   http://www.dtweed.com/circuitcellar/caj00160.htm#2820

There are COTS chips such as the Philips SAA2505 and Apogee DDX4100
that can basically do what you want to do.

Thanks Jaime for mentioning the new kit. 

The package is described in detail on our website. It comes with Altera 
tools (including a ByteBlaster) and Analog Devices tools. The board 
functions just like an Analog Devices EZ-Kit LITE development board since 
we have a license for the on board debugger.

The special pricing is limited to one per customer (we would like to sell 
you production boards). The price is being subsidized by Analog Devices 
and Altera and the kit (ADDS-21261/Cyclone) is being sold exclusively by 
Arrow Electronics. The promotional price is not forever and I am happy to 
say they are selling well.
