According to the information from ADI website, Visual DSP exists no longer. Crosscore is official successor, albeit not quite compatible. Does this imply near termination of BlackFin and Sharc product lines? Is this a sign that entire ADI goes south? Vladimir Vassilevsky DSP and Mixed Signal Consultant www.abvolt.com

Hi. I want to use a very large FFT (65536 samples) on a Sharc 21065L. But I encountered a problem with the ADI FFT (rfft65536) with my DSP: the twiddle-factors need to be in the PM, but that is far too much data for the internal memory of the 21065. I tried the FFT from "Numerical Recipies in C", but the results are not really correct, there are errors for low frequencies. Now I'm looking for...

I've just got a couple of samples of the new ADSP-21262 SHARC DSP (1200 MFLOPS!) in the LQFP package. It is a masked-ROM device, and I wondered if there was likely to be anything useful in the ROM. I've started designing a simple PCB so that I can play with them, it'll consist basically of the '21626 and a suitable codec. Leon

I am starting to learn the DSP by using the Analog DSP. I am wondering which one is "best" - I do not have target application now. just for learning DSP. What I mean "best" is that the chip architecture is current, stable, widely used, easy use(?), and the support for the chip last longer - some chip might be outdated. TigerSharc? Sharc? - will be replaced by TigerSharc? Blackfin?

I'm remarkably new to DSPs, and I've got this TigerSHARC. Well, four of them, but I'm just fiddling with one at the moment. I'm used to coding for desktop apps, and whilst my C code runs fine I'm not sure about how long various operations take in terms of clock cycles on this T'SHARC. Looking through the various manuals, I note it has a nice bit barrel and also a multiplication unit. I ...
