jtag sufficient?

Started by myren April 1, 2004
i'm interesting in ham radio systems (particularly direct sampling 
techniques), and although i will be starting with FPGA's i would like to 
advance to encorporating DSP's into my design.  I am a broke college 
student now though, and was wondering if the JTAG gear i buy for FPGA 
programming would most likely work for DSP's as well?

If not, what sort of interfaces do DSP's usually use?

Even with JTAG everyone has their own proprietary interface. Spectrum Digital has some very cost-effective evaluator boards for TI's DSPs that have the JTAG translation hardware built in. Analog Devices used to use a full-proprietary interface; I don't know if they've gone to JTAG or not. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com
ADI also uses JTAG, and their evaluation boards have a built in USB
connection to the DSP.
