Bandpass subsampling?30 (6/19/2013 3:53:44 PM) comp.dsp
There is a need to estimate power which falls into given wide (~30% of
Nyquist) bandwidth. Power spectrum doesn't matter; just overall number.
The power estimate is not needed often; so a decimation facto... Vladimir
AM3358 DSP benchmark10 (6/15/2013 4:19:26 AM) comp.dsp
There is necessity to port BlackFin VDSP code to TI AM3358. The later is
Cortex A8 core with NEON SIMD coprocessor (???).
BlackFin code uses DSP library; namely FFT functions provided with VDSP.
The BTD... Vladimir
VDSP is dead1219 (2/20/2013 4:33:17 PM) comp.dsp 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?... Vladimir
Non-text format for source code6224 (1/31/2013 7:20:31 PM) comp.arch.embedded For great many reasons, it would be convenient to have source code in some
rich format rather then plain ASC text. I could think of embedding
illustrations, links and data into file, custom coloring, indivi... Vladimir
Coherent MFSK1120 (11/28/2012 4:34:36 PM) comp.dsp There are communication systems with orthogonal multitone physical layer.
That is, one of N frequencies in the set is sent at a time. An example of
such system is "Olivia": http://en.wikipedia.org/wiki/Oliv... Vladimir
Video Controller :: Best Practices533 (11/19/2012 3:40:51 PM) comp.arch.embedded I have to design a video subsystem for instrument. Nothing really fancy;

Flag for missed interrupt?1841 (10/20/2012 3:39:22 PM) comp.arch.embedded While developing embedded systems, many times I thought it would be useful

hardware if interrupt request was set again before the i... Vladimir
Random numbers4639 (10/14/2012 2:38:47 AM) comp.dsp Just wonder what methods do you prefer for generation of pseudo random
numbers for applications like simulation or dithering.
Clipped sum of sinusoids2136 (10/2/2012 3:26:10 PM) comp.dsp Let's say there is a sine wave signal, and an amplifier with limited output
amplitude. To produce maximum output power at fundamental frequency, the
sinusoid could be clipped into square wave. So far so goo... Vladimir
Autocorrelation rocks for Engine RPM193 (6/10/2013 10:12:29 PM) comp.dsp A while ago I posted a question about how to extract pitch information

developed which displays the RPM of an engine based on the sound it
