Thanks for your reply Daixiwen.
I want to ask you was your last reply about the DE-70 board or your talking about the fpgas in general?
So which dsp do you advice me to use because there are a lot of dsps in Texas Instrument?And which on is suitable for my project and has a professional Kit that has a touch screen and can be extendable?
And what about the DSP Development Kits that the altera provides are they suitable and can I add a touch screen module to them because I didn't find touch screen module to them If you know about one please tell me about?
