Version: 0.2
Here is the third release of the comp.dsp FAQ. Rather obviously it has a
long way to go. I am eagerly seeking out information on all topics, from
the best layout (e.g. should chips and prototype boards be another FAQ?) to
a good annotated list of DSP articles and reference books. Please email
your suggestions to hards4@ee.adfa.oz.au. My meta-comments are all in curly
braces {like this}
You can ftp the very latest version of this FAQ from: evans.ee.adfa.oz.au

0. What is comp.dsp?
Comp.dsp is a worldwide UseNet news group that is used to discuss various
aspects of digital signal processing. It is unmoderated, though we try to
keep the signal to noise ratio up :-). If you need to ask a question that
isn't in the FAQ, and can't figure out how to post, consult
news.newusers.questions. Other relevant news groups are comp.compression,
sci.image.processing.

=======================================================================
3. Where can I get the Motorola DSP C compilers source?
There are two separate compiler sources. One is the port of gcc 1.40 done
by Andrew Sterian (ASTERIAN@BNR.CA) and the other is a port of gcc 1.37.1
done by Motorola and returned to the FSF. These may be portable to gcc2.x.x
with some effort required. Neither of these compilers includes an
assembler, though a publicly available assembler exists, thanks to Quinn
Jensen (jensenq@qcj.icon.com). The current version is 1.1, and it is
posted to alt.sources, so look for it on mirrors of this newsgroup (like
wuarchive.wustl.edu)
For more information on the Motorola compilers try contacting Jeff Enderwick
(jeff@dsp.sps.mot.com).
>From: Andrew (A.) Sterian <ASTERIAN@BNR.CA>
The source code for the Moto compiler is available on nic.funet.fi.
My own DSP56K port has bowed to Motorola's version. My DSP56156 port is
still the only DSP56156 compiler around and I have just released an updated
version of it. Both this compiler and the previous incarnation are archived
on wuarchive.wustl.edu (in the usenet/alt.sources directory) amongst other
places.
=======================================================================
4. Where can I get a free compiler for the C30/C40 ?
Currently, you can't. {any corrections to this - anyone working on it?}
=======================================================================
5. OK then, where can I pay money for a C30/C40 compiler ?
TI has a C30/C40 compiler for C. Tartan has an ADA compiler. Computer
Motion has a C++ compiler for C3x based on GNU C++, but it appears they
haven't returned the deltas to FSF.
=======================================================================
6. Where can I get some algorithms?
These archives contain things such as matrix operations, FFT's and
generally useful things like that, as opposed to complete applications.
(1) there is host ux1.cso.uiuc.edu - log in as anonymous, get the
file math/README. It summarises the contents of the archive.
(2) there is the netlib host which also serves some of this software via
email. Try mail to netlib@ORNL.GOV with "send help" in the subject
field.
For Europe:
Internet: netlib@nac.no
EARN/BITNET: netlib%nac.no@norunix.bitnet
X.400: s=netlib; o=nac; c=no;
EUNET/uucp: nac!netlib
For the Pacific, try
netlib@draci.cs.uow.edu.au
For background about netlib, see Jack J. Dongarra and Eric Grosse,
Distribution of Mathematical Software Via Electronic Mail,
Comm. ACM (1987) 30,403--407.
A similar collection of statistical software is available from
statlib@temper.stat.cmu.edu.
The symbolic algebra system REDUCE is supported by
reduce-netlib@rand.org.
(3) It may be possible to get an extensive set of fortran routines
produced by the Naval Surface Warfare Centre. { Any one got more data ?}
(?) if you don't know where to find what you're after, try archie.
=======================================================================
7. Yeah, but thats all in fortran and I only wanted some simple stuff for
my 56000...
Firstly, not all of the above stuff is in fortran, some is in C, and you
could always use the f2c fortran to C compiler (use archie to locate the
nearest archive of f2c).
Alternatively, Dr BuB (the Motorola BBS) is mirrored on:
calvin.stanford.edu (36.14.0.43) in /motorola
bode.ee.ualberta.ca (129.128.16.96) in /pub/dos/motorola

doc.ic.ac.uk (146.169.3.7) in
/computing/systems/motorola/digital-signal-processing/dr.bub.sources
Also try nic.funet.fi in /pub/ham/dsp for a lot of good stuff on
communications uses, including some hardware

9. How does pitch perception work, and how do I implement it on my DSP chip?
From: Malcolm Slaney, Apple Computer, and John Lazzaro, UC Berkeley.
Pitch is officially defined as "That attribute of auditory sensation
in terms of which sounds may be ordered on a musical scale." Several
good examples illustrating the subtleties of pitch perception are
included in the "Auditory Demonstrations CD" which is available from
the Acoustical Society of America, Woodbury, NY 10797 for $20.
A good general reference about the psychology of pitch perception is
the book
"An Introduction to the Psychology of Hearing," by B. C. J.
Moore, Academic Press, London, 1989.
This book is available in paperback and makes a good desk reference.
An algorithm implementation that matches a large body of psychoacoustical
work, but which is computationally very intensive, is presented in the paper:
Malcolm Slaney and Richard Lyon, "A Perceptual Pitch Detector,"
Proceedings of the International Conference of Acoustics, Speech,
and Signal Processing, 1990, Albuquerque, New Mexico.
The definitive papers describing the use of such a perceptual pitch
detector as applied to the classical pitch literature is in:
Ray Meddis and M. J. Hewitt. "Virtual pitch and phase
sensitivity of a computer model of the auditory periphery. "
Journal of the Acoustical Society of America 89 (6 1991): 2866-2682.
and 2883-2894.
The current work that argues for a pure spectral method starts with the work
of Goldstein:
J. Goldstein, "An optimum processor theory for the
central formation of the pitch of complex tones," Journal
of the Acoustical Society of America 54, 1496-1516, 1973.
Two approaches are worth considering if something approximating pitch
is appropriate. The people at IRCAM have proposed a harmonic analysis
approach that can be implemented on a DSP
Boris Doval and Xavier Rodet, "Estimation of Fundamental Frequency
of Musical Sound Signals," Proceedings of the 1991 International
Conference on Acoustics, Speech, and Signal Processing, Toronto,
Volume 5, pp. 3657-3660.
The classic paper for time domain (peak picking) pitch algorithms is:
B. Gold and L. Rabiner, "Parallel processing techniques for estimating
pitch periods of speech in the time domain," Journal of the Acoustical
Society of America, 46, pp 441-448, 1969.
Finally, a word of caution: Pitch is not single-valued. We can hear a
sound and match it to several different pitches. Imagine the number
of instruments in an orchestra, each with it's own pitch. Even a
single sound can have more than one pitch. See for example
Demonstration 27 from the ASA Auditory Demonstrations CD.
=======================================================================
10. What are the available DSP chips and chip architectures?
