Info regarding which DSP board to buy

Started by Unknown August 22, 2005
Hi all,

I am considering buying a DSP board to get some hands-on experience in
working on DSP. I have theoretical knowledge of DSP but zero practical
experience. I will be doing some projects on DSP in say 3-4 months time. So
i need to be prepared for that. (i have no idea what project i'll put in)
I need some help regarding which one to buy. I am not having a concrete idea
about what application i intend to do. Just have a feel that i may work on
speech codecs. Cost is one of my major factors. So i investigated some
boards which cost less that $200.

 The boards that i have considered so far are
1. TMS320C50 board which is available for as low as $150 (planning to use
trial version of codeComposer)
2. TMS320C31 board which is a floating point DSP for almost the same cost.
3. Freescale (motorola ) boards for about $100 with codeWarrior software
IDE.
4. ADSP 2181 for about  $150.

Please clarify some points-

1)I heard that it is always better to go for TI floating point processors
are more companies are using it...Is it true?
2)I was adviced against going for motorola processors as my experience may
not be useful if i work on TI processors in the future?
3)Also please advice me on whether should i stretch my financial constraints
a bit more and consider buying a latest DSP processor, say TMS320C6xx
series?
4) Or is it okay if i just have experience in "some" processor.. i can adapt
to any processor later. ( of course how fast i can adapt is relative and
varies from person to person, but generally speaking what is the opinion?)


Finally if u know some vendor who ships DSP boards, please let me know.
thanx in advance.

Some other boards For a while Analog devices had their blackfin EZdsp kits for US$150 which are now at US$495. Cheapest for Analog Devices dsp's is the blackfin stamp at US$169 at digikey.com search on BF533-STAMP Have a choice of using blackfin-gcc or Visual dsp http://www.analog.com/en/prodDesc/0,2895,BF533%2DSTAMP%5F0,00.html http://www.analog.com/UploadedFiles/Technical_Articles/189464661uClinuxWhiteWP_WEB.pdf http://blackfin.uclinux.org/ http://blackfin.uclinux.org/projects/stamp/ http://www.analog.com/en/epHSProd/0,,BF533-STAMP,00.html http://www.analog.com/processors/processors/blackfin/crosscore/index.html http://docs.blackfin.uclinux.org/doku.php?id=buy_stuff would need the AD1836A Audio Codec Card for audio output I think Danville Signal had a offer on their dspstak 21261zx for a while http://www.danvillesignal.com/ TI dsp starter kits are also around US$495 Can get a board from freescale for their 56f8323 chip http://www.freescale.com/webapp/sps/site/taxonomy.jsp?nodeId=0127956292 http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MC56F8300DSK&nodeId=0162468636QNBX&tid=tdfp http://rocky.digikey.com/WebLib/Motorola/Web%20Data/MC56F8300DBUM.pdf http://rocky.digikey.com/WebLib/Motorola/Web%20Data/MC56F8300DEMOPB.pdf US$79 from digikey.com search on MC56F8300DSK www.newmicros.com sell some 56f805 and 807 boards look at their pod products Cheapest would probably be the dspics from microchip could easily make your own board using a dip chip + crystal http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=75 http://www.microchip.com/ParamChartSearch/chart.aspx?branchID=806&mid=14&lang=en&pageId=75 microchip boards http://buy.microchip.com/ProductDetails.aspx?Catalog=BuyMicrochip&Category=dsPIC%20Boards%20and%20Kits&mid=13 http://www.geocities.com/leon_heller/dspic.html Alex

In the general purpose market, ADI & TI have about equal marketshare. IMHO, the SHARC is much easier to use and program.
> 2)I was adviced against going for motorola processors as my experience
Experience with any DSP family is probably useful. Freescale (Motorola) has lost a lot of market share in the last few years.

All the DSPs you mentioned previuously are essentially obsolete. I would suggest starting with a more contemporary DSP. Probably best choices are dev kits from ADI or TI or one of our dspstak SHARC boards. All of these systems come with software tools which can be very experience otherwise.

Obviously, experience in a specific processor family that matches with a prospective employer is best, experience with any DSP is better than none, etc. When you are looking for a job, you want to have skills that your peers do not have. In marketing we call it a USP (Unique Selling Proposition). What skills will make you special? There may be more students with some TI experience which might mean that ADI is a better choice. I started out my career as an analog engineer when all my peers were mostly digital. I argued then (and now) that its harder to find a good analog engineer than a good digital engineer.

We make boards that include tools. Our least experience (but not necessarily your best choice) is $250 for a ADSP-2186 based system. Our SHARC based dev systems are about the same proice as an EZ-Kit. -- Al Clark Danville Signal Processing, Inc. -------------------------------------------------------------------- Purveyors of Fine DSP Hardware and other Cool Stuff Available at http://www.danvillesignal.com
Ok thanks...

Anyone knows some vendors in bangalore , india?
