SUBJ : comp.dsp FAQ [1 of 4] CONF : (-18) DSP
--------------------------------------------------------------
Archive-name: dsp-faq/part1
Last-modified: Sun May 30 1993
Version: 1.1
Welcome to the comp.dsp FAQ. We are seeking 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 comp-dsp-faq@ohm.Berkeley.EDU.
Meta-comments are all in curly braces, {like this}. Acknowledgements to
people responsible for articles and/or bits of information are in
square brackets, [like so].
You can ftp the very latest version of this FAQ from: evans.ee.adfa.oz.au
(131.236.30.24) in pub/dsp/dsp-faq.help, or from copernicus.Berkeley.EDU
in dsp-faq.help.*.
In version 1.1 of the FAQ, we've included a list of DSP-related FTP sites
at the end of the FAQ (section 7). Be sure to check this if you're looking
for an FTP site, as it may have more up-to-date information on than the text
in the body the FAQ.

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, comp.speech, and sci.image.processing.

An elegant method for designing a time-discrete solution for
realization of a spectral window which is ideal from an energy
concentration viewpoint. This window is one that concentrates the
maximum amount of energy in a specified bandwidth and hence provides
optimal spectral resolution. Unlike the Kaiser window, this window is
a discrete-time realization having the same objectives as the
continuous-time prolate spheroidal function; at the expense of not
having a closed form solution. [Joe Campbell, jpcampb@afterlife.ncsc.mil]

Q1.2: Where can I get free software for general DSP?
The packages listed below are mostly for general purpose DSP, that is,
DSP that is not specific to a particular programmable DSP chip. See
the later sections in the FAQ for software relevant to a particular
programmable DSP chip.
According to Brian Evans: "There was an entire session on this subject
[free DSP software] at ICASSP '92, chaired by Dr. Sally Wood and
Dr. James McClellan. It appears in Volume 4 of the Proceedings, pages
73-112. There will be another such session at ICASSP '93." [Brian Evans,
evans@eedsp.gatech.edu] Much of the information below is from Brian's mail.
--------------------------------------------------
Q1.2.1: What is Gabriel? Where can I get it?
Package: Gabriel
Description:
Gabriel was a hierarchical block diagram environment for prototyping
signal processing systems on single or multiple processors. It has
been superceded by Ptolemy (see below), and is no longer available.
--------------------------------------------------
Q1.2.2: What is Ptolemy? Where can I get it?
Package: Ptolemy
Description:
Ptolemy provides a highly flexible foundation for the specification,
simulation, and rapid prototyping of systems. It is an object
oriented framework within which diverse models of computation can
co-exist and interact. For example, using Ptolemy a data-flow
system can be easily connected to a hardware simulator which in turn
may be connected to a discrete-event system, etc. Because of this,
Ptolemy can be used to model entire systems.
In addition, Ptolemy now has code generation capabilities. From a
flow graph description, Ptolemy can generate both C code and DSP
assembly code for rapid prototyping. Note that code generation is
not yet complete, and is included in the current release for
demonstration purposes only.
Ptolemy has been used for a broad range of applications including
signal processing, telecomunications, parallel processing, wireless
communications, network design, radio astronomy, real-time systems,
and hardware/software co-design. Ptolemy has also been used as a lab
for signal processing and communications courses. Currently Ptolemy
has hundreds of users in over 100 sites, both in industry and academia.
Ptolemy is available for the Sun 4 (sparc), DecStation (MIPS), and HP
(HP-PA) architectures. Installing the system requires 49 Mbytes for
Ptolemy (64 Mbytes after you optionally rebuild) and 16 Mbytes for the
Gnu tools subset. At least 8 Mbytes of physical memory are required.
Ptolemy has been developed at UC Berkeley over the past 3 years.
Further information, including papers and the complete release
notes, is available from the FTP site.
A license is no longer required to receive Ptolemy. The source code,
binaries, and documentation are available by anonymous ftp from

FOR STUDENTS: Prentice Hall has published a student edition of matlab
which contains a book and set of disks for PCs and Macs. The software
is limited only in matrix size (32 x 32 matrix; 1024 elements) and in
its ability to import or call C or Fortran subroutines. On the plus
side, it is able to run without a coprocessor (it will use one if it is
present) and it includes a subset of the Signal Processing and Controls
Toolboxes, The Signals and Systems Toolbox, which provides for added
functionality. Book only (about US$30): ISBN = 0138560064; Book + disk:
(about US$50 ISBN=0-13-855974-0 for 3.5" or ISBN=0-13-855982-1 for 5.25
Macintosh version: ISBN=0-13-855990-2. There will be related books out
by mid to late 1993 : Computer Aided Signal Processing with MATLAB, by
Burrus, Oppenheim, McClellan, Parks, Schafer, and Schussler; and Signal
Processing : A Computer Approach, by Etter. More books in this MATLAB
Curriculum Series are planned. For general info: matlab@prenhall.com
[From the Matlab Users Group (Editor, hwilson@ua1vm.ua.edu)]
--------------------------------------------------
Q1.2.6: What are the Signal Processing Packages for Mathematica?
Where can I get them?
Package: Signal Processing Pacakages (SPP) and Notebooks.
Description:
Public domain extensions to Mathematica. Enables the symbolic
manipulation of signal processing expressions: 1-D discrete/continuous
convolutions and 1-D/m-D linear transforms (Laplace, Fourier, z, DTFT,
and DFT). For linear transforms, you can specify your own transform
pairs and see the intermediate computations. Great for showing students
how to take transforms, or for deriving input-output relationships in a
transform domain. Additional abilities include analog filter design,
solving DE's using transforms, converting signal processing expressions
to their equivalent TeX forms, and number theoretic operations (Bezout
numbers, Smith Form decompositions, and matrix factors). Accompanying
SPP are tutorial notebooks on analog filter design, Fourier analysis,
piecewise convolution, and the z-transform (includes a discussion of
fundamentals of digital filter design). These Notebooks illustrate
difficult concepts (such as the flip-and-slide view of convolution)
through animation. A Notebook reader is available in the public domain
for Macintosh computers (a BinHexed version is on the ftp site).
FOR STUDENTS: A student version of Mathematica is available for $175.
The price includes a copy of the reference manual. The only drawbacks
to the student version are that the floating point coprocessor is dis-
abled and that upgrades cannot be ordered.
Contact: Brian Evans, evans@eedsp.gatech.edu.
To obtain: anonymous ftp to gauss.eedsp.gatech.edu (130.207.226.24).
(available in UNIX, Mac, and MS-DOS archive formats).
--------------------------------------------------
Q1.2.7: What is the Control Systems Analysis Packages for Mathematica?
Where can I get them?
Package: Control Systems Analysis Package (COSYPAK) and Notebooks
Description: Public domain extension to Mathematica. Classical and
state-space control analysis and design methods. The Notebooks
supplement the material in the textbook "Modern Controls Theory" by
Ogata. Largely based on the Signal Processing Packages (SPP, see above).
Contact: Dr. Sreenath, sree@veda.esys.cwru.edu.
To obtain: anonymous ftp veda.esys.cwru.edu (129.22.40.9).

Description: Public domain extension to Maple.
Contact: Tony Richardson, amr@mpl.ucsd.edu.
To obtain: anonymous ftp to ftp.egr.duke.edu
file pub/maple/linsys1.2.tar.Z.
--------------------------------------------------
Q1.2.10: Where can I get text to speech conversion software?
Free (but not public domain) text to speech conversion software is
available via anonymous ftp from wilma.cs.brown.edu in the pub directory
as speak.tar.Z. It will compile and run on a SPARC's built-in audio
after modifying speak.c with the path of your libaudio.h (e.g.,
/usr/demo/SOUND/libaudio.h). It's a simple phoneme concatenation
system with commensurate synthesized speech quality (a directory of
phoneme audio files is included). [Joe Campbell, jpcampb@afterlife.ncsc.mil]
--------------------------------------------------
Q1.2.11: Where can I get filter design software?
There are filter design programs available via anonymous FTP. The
following are summarized here and discussed in greater detail below:
1. August 1992 IEEE Trans. on Signal Processing: METEOR FIR filter design
program.
2. DFIR FIR filter design program.
3. Netlib IIR filter design.
4. IEEE Press "Programs for Digital Signal Processing".
-----
The August 92 issue of IEEE Transactions on Signal Processing there is
a paper entitled "METEOR: A Constraint-Based FIR Filter Design Program"
by Kenneth Steiglitz, Thomas W. Parks and James F. Kaiser. They
describe an FIR design program which allows specification of the target
frequency response characteristics in a fairly generalised and flexible
way. As well as designing filters, the program can optimise filter
lengths and push band limits.
The paper contains a footnote which says "Pascal and C versions of
source code are available to anonymous ftp at princeton.edu in the
directory /pub as meteor.p, form.p, meteor.c and form.c".
True, they are. They appear to work. The Pascal versions have been
put through p2c to get the C versions; all the needed Pascal library
stuff is included in the C versions and they built error-free out of
the box for me on an SGI machine.
One catch is, there is no manual - you need the paper to know how to drive
the programs.
[Steve Clift, clift@ml.csiro.au]
-----
Another public domain filter design package is DFIR, for FIR filter designs.
It includes design capabilities for: equiripple linear phase multiband
filters,
linear phase differentiators, linear phase Hilbert transform filters, MMSE
interpolating filters and equiripple Nyquist filters. It is written in
Fortran 77 and has been tested on DECStations and Suns.
It is available via anonymous ftp from aldebaran.ee.mcgill.ca in "pub/dfir".
Additionally, a package to plot filter responses is available in
"pltfilter-V2R0.tar.Z".
[Peter Kabal, via Witold Waldman]
-----

Q2.2: What are CELP and LPC? Where can I get the source for CELP and LPC?
CELP stands for "code excited linear prediction". LPC stands for
"linear predictive coding". They are compression algorithms used for
low bit rate (2400 and 4800 bps) speech coding.
The U.S. DoD's Federal Standard 1016 (FS 1016) based 4800 bps code

=======================================================================
Q2.3: What is ADPCM? Where can I get source for it?
ADPCM stands for Adaptive Differential Pulse Code Modulation. It is a
family of speech compression and decompression algorithms. A common
implementation takes 16-bit linear PCM samples samples and converts
them to 4-bit samples, yeilding a compression rate of 4:1.
There is public domain C code available via anonymous ftp at
ftp.cwi.nl in /pub/adpcm.shar written by Jack Jansen (email
Jack.Jansen@cwi.nl). It is very programmer-friendly. The ADPCM code
used is the Intel/DVI ADPCM code which is being recommended by the IMA
Digital Audio Technical Working Group. It allows the following calls:
adpcm_coder(short inbuf[], char outbuf[], int nsample,
struct adpcm_state *state);
adpcm_decoder(char inbuf[], short outbuf[], int nsample,
struct adpcm_state *state);
The routines have been tested on an SGI Indigo running Irix 4.0.2 and
on a Sparcstation 1+ running SunOS 4.1.1. On a Sun, the code will
compress at 250Ksample/sec and decompress at 300Ksample/sec. On an
SGI, the compressor runs at 350Ksample/sec and the decompressor at
700Ksample/sec.
Note that this is NOT a CCITT G722 coder. The CCITT ADPCM standard is
much more complicated, probably resulting in better quality sound but
also in much more computational overhead.
[From Dan Frankowski, drankow@cs.umn.edu; Jack Jansen, Jack.Jansen@cwi.nl]
=======================================================================
Q2.4: What is GSM? Where can I get source for it?
The README file for GSM says:
GSM 06.10 13 kbit/s RPE/LTP speech compression available
--------------------------------------------------------
The Communications and Operating Systems Research Group (KBS) at the
Technische Universitaet Berlin is currently working on a set of
UNIX-based tools for computer-mediated telecooperation that will be
made freely available.
As part of this effort we are publishing an implementation of the
European GSM 06.10 provisional standard for full-rate speech
transcoding, prI-ETS 300 036, which uses RPE/LTP (residual pulse
excitation/long term prediction) coding at 13 kbit/s.
GSM 06.10 compresses frames of 160 13-bit samples (8 kHz sampling
rate, i.e. a frame rate of 50 Hz) into 260 bits; for compatibility
with typical UNIX applications, our implementation turns frames of 160
16-bit linear samples into 33-byte frames (1650 Bytes/s).
The quality of the algorithm is good enough for reliable speaker
recognition; even music often survives transcoding in recognizable
form (given the bandwidth limitations of 8 kHz sampling rate).
The interfaces offered are a front end modelled after compress(1), and
a library API. Compression and decompression run faster than realtime
on most SPARCstations. The implementation has been verified against the
ETSI standard test patterns.

Q2.5: How does pitch perception work, and how do I implement it on my DSP
chip?
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:
B.C.J. Moore, "An Introduction to the Psychology of Hearing",
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 its own pitch. Even a
single sound can have more than one pitch. See for example
Demonstration 27 from the ASA Auditory Demonstrations CD.
[The above from Malcolm Slaney, Apple Computer, and John Lazzaro,
U.C. Berkeley.]
=======================================================================
Q2.6: What standards are there for digital audio? What is AES/EBU?
What is S/P-DIF?
The "AES/EBU" (Audio Engineering Society / European Broadcast Union)
digital audio standard is probably the most popular digital audio
standard today. Most consumer and professional digital audio devices
(CD players, DAT decks, etc.) that feature digital audio I/O support
AES/EBU.
AES/EBU is a bit-serial communications protocol for transmitting
digital audio data through a single transmission line. It provides two
channels of audio data (up to 24 bits per sample), a method for
communication control and status information ("channel status bits"),
and some error detection capabilities. Clocking information (i.e.,
sample rate) is derived from the AES/EBU bit stream, and is thus
controlled by the transmitter. The standard mandates use of 32 kHz,
44.1 kHz, or 48 kHz sample rates, but some interfaces can be made to
work at other sample rates.
AES/EBU provides both "professional" and "consumer" modes. The big
difference is in the format of the channel status bits mentioned above.
The professional mode bits include alphanumeric channel origin and
destination data, time of day codes, sample number codes, word length,
and other goodies. The consumer mode bits have much less information,
but do include information on copy protection (naturally). Additionally,
the standard provides for "user data", which is a bit stream containing
user-defined (i.e., manufacturer-defined) data. According to Tim
Channon, "CD user data is almost raq CD subcode; DAT is StartID and
SkipID. In progfessional mode, there is an SDLC protocol or, if DAT,
it may be the same as consumer mode."
There physical connection media are commonly used with AES/EBU:
balanced (differential), using two wires and shield in three-wire microphone
cable with XLR connectors; unbalanced (single-ended), using audio coax cable
with RCA jacks; and optical (via fiber optics).
"S/P-DIF" (Sony/Philips Digital Interface Format) typically refers to
AES/EBU operated in consumer mode over unbalanced RCA cable. Note
that S/P-DIF and AES/EBU mean different things depending on how much
of a purist you are in the digital audio world; see the Finger article
below.

Q2.7: What is mu-law encoding? Where can I get source for it?
Mu-law (also "u-law") encoding is a form of logarithmic quantization
or companding. It's based on the observation that many signals are
statistically more likely to be near a low signal level than a high
signal level. Therefore, it makes more sense to have more quantization
points near a low level than a high level. In a typical mu-law system,
linear samples of 14 to 16 bits are companded to 8 bits. Most telephone
quality codecs (including the Sparcstation's audio codec) use mu-law
encoded samples.
Desktop Sparc machines come with routines to convert between linear and
mu-law samples. On a desktop Sparc, see the man page for audio_ulaw2linear
in /usr/demo/SOUND/man.
Craig Reese posted the source of similar routines to comp.dsp in August '92.

Q2.8: How can I do CD <-> DAT sample rate conversion?
CD players use a 44.1 kHz sample rate, whereas DAT uses a 48 kHz sample rate.
This means that you must do sample rate conversion before you can get data
from a CD player directly into a DAT deck.
[From Ed Hall, edhall@rand.org:]
For a start, look at "Multirate Digital Signal Processing" by Crochiere
and Rabiner (see FAQ section 1.1).
Almost any technique for producing good digital low-pass filters will be
adaptable to sample-rate conversion. 44.1:48 and vice-versa is pretty
hairy, though, because the lowest whole-number ratio is 147:160. To do
all that in one go would require a FIR with thousands of coefficients,
of which only 1/147th or 1/160th are used for each sample--the real
problem is memory, not CPU for most DSP chips. You could chain several
interpolators and decimators, as suggested by factoring the ratio into
3*7*7:2*2*2*2*2*5. This adds complexity, but reduces the the ter of
coefficients required by a considerable amount.
In any case, your local DSP guru will probably be able to suggest a good
program for designing digital filters (this is a good general question
for the net, anyway). This is one case where going beyond the simpler
windowed-sinc-based approaches might pay off (and I'm afraid I can't
recommend any readily available programs myself).

Q3.2: Software for Motorola DSPs.
=======================================================================
Q3.2.1: Where can I get a free assembler for the Motorola DSP56000?
A free assembler for the Motorola DSP56000 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 that
newsgroup (like wuarchive.wustl.edu).
=======================================================================
Q3.2.2: Where can I get a free C compiler for the Motorola DSP56000?
There are two separate compiler sources for the Motorola DSP56000. One
is the port of gcc 1.40 done by Andrew Sterian (asterian@eecs.umich.edu) and
the other is a port of gcc 1.37.1 done by Motorola and returned to the
FSF. Andrew's port has bowed to Motorola's version. Both may be
portable to gcc2.x.x with some effort required. Neither of these comes
with an assembler, but you can get a free DSP56000 assembler elsewhere
(see Q3.2.1 above).
The Motorola gcc source is available for FTP from:
nic.funet.fi ~pub/ham/dsp/dsp56k-tools/dsp56k-gcc.tar.Z
evans.ee.adfa.oz.au pub/micros/56k/g56k.tar.Z
From Andrew Sterian, asterian@eecs.umich.edu:
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.
=======================================================================
Q3.2.3: Where can I get algorithms and libraries for Motorola DSPs?
What is the the ter for the Motorola DSP BBS?
Motorola runs "Dr. Bub", a bulletin board for DSPs containing source code
for various libraries and algorithms. You can call it at (512) 891-3771
(9600, 4800, 2400, 1200 bps) or (512) 891-3773 (2400/1200/300 bps).
Format is 8 data bits, no parity, 1 stop bit). Log in as "guest" to
browse the system, or you can open an account by entering "new" at the
account name prompt. [John Fisher, johnf@dsp.sps.mot.com]
Alternatively, Dr. BuB is mirrored on the following sites:
calvin.stanford.edu (36.14.0.43) in /motorola
bode.ee.ualberta.ca (129.128.16.96) in /pub/dos/motorola
nic.funet.fi (128.214.6.100) in /pub/misc/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.
ccrma-ftp.stanford.edu also has a variety of DSP code (much of it NeXT
specific, see below), including the following for the DSP56000:
pub/clm.tar.Z "CLM", a package aimed mainly at composers doing
computer music in Common Lisp, but includes a Lisp
56000 assembler, debugger, loader, large libraries of
DSP56000 routines useful in computer music, and
a compiler from a subset of Common Lisp to
DSP56000 code. [bil@ccrma.stanford.edu]
=======================================================================
Q3.2.4: Where can I get NeXT-compatible Motorola DSP56001 code?
Try the following from ccrma-ftp.Stanford.EDU:
DSP programs for the NeXT platform:
pub/DSP/resample.tar.Z Audio sampling-rate conversion and FIR
filter design.
pub/DSP/ResoLab2.1.tar.Z Interactive filter instrument; sources now
included, online help.
pub/DSP/Spectro.Z Spectrum analysis tool, with source code.
pub/DSP/WaveFormEditor.tar.Z Jean Laroche's real-time waveform editor,
with DAJ's additions.
DSP programming examples for the NeXT platform:
pub/DSP/dsp_dma_stream.tar.Z Fast DSP DMA programming example (two-way
DMA).
pub/DSP/JeanLaroche.tar.Z Low-level sound and DSP programming examples
and docs.

Q3.3: Software for Texas Instruments DSPs.
=======================================================================
Q3.3.1: Where can I get free algorithms or libraries for TI DSPs?
What is the number for the TI DSP BBS?
nic.funet.fi has some old, apparently public domain, assembler and
related tools from TI for the TMS320 family. [Antti-Pekka Virtanen,
antsu@utu.fu]
The TI DSP bulletin board is at (713) 274-2323 (300, 1200, 2400, or 9600 bps;
8 data, 1 stop, no parity).
evans.ee.adfa.oz.au has a mirror of the TI DSP bulletin board in
"mirrors/tibbs". See the "00README" file at the top of the
directory tree for info. Please restrict FTP session to outside of
8 am to 6 pm local time (10 pm to 8 am GMT).
This is mirrored from ti.com, in /tms320bbs. The TI site is
the official one, but has no user contributed software.
[Brad Hards, hards4@ee.adfa.oz.au]
{ If anyone knows of any other sources for TI DSP software, please let
us know at comp-dsp-faq@ohm.Berkeley.EDU. Thanks! }
=======================================================================
Q3.3.2: Where can I get a free C compiler for the TI TMS320C30?
Sonitech (see vendors list) has a gcc based TMS320C30 C compiler
that was originally done Computer Motion. Sonitech sells it
for $995, but under the terms of the Gnu Public License, other
people can then give it away. While we haven't heard of any
ftp sites yet, there are bound to be some soon.
=======================================================================
Q3.3.3: Where can I get a free assembler for the TI TMS320C30?
Ted Rossin has written an assembler and linker for the TMS320C30. In
his words, "It is somewhat limited by the fact that it can't handle
expressions but it has worked fine for me over the past few years.
There is no manual because it is a clone of the TI assembler and
linker. However the linker command files use a different (easier to
use) syntax. It runs on HP-UX workstations, Macs, IBM clones and
believe it or not the Atari-ST (because I developed the code on it)."
It is available for anonymous ftp from schutz.ee.uts.edu in
~/pub/DSP/c30/as30.tar.Z".
[Ted Rossin, rossin@fc.hp.com]
=======================================================================
Q3.4: Software for Analog Devices DSPs.
=======================================================================
Q3.4.1: Where can I get algorithms or libraries for Analog Devices DSPs?
What is the number for the Analog Devices DSP BBS?
The number for the Analog Devices DSP BBS is (617) 461-4258 (300, 1200,
2400, 9600, 14400 bps), 8N1.

Q5.0 What DSP operating systems are available?
[This was researched and written by Chuck Corley (chuckc@sr.hp.com)]
Some designers need to use an operating system with a DSP
processor and others don't. The need for DSP operating system seems to
depend on the task(s) to be performed.
For simple DSP tasks where the DSP is doing only a single
repetitive function, an operating system is usually not needed and
could get in the way.
When the number and complexity of DSP tasks increase, an
operating system of some type may be needed in order to allocate system
resources (RAM, etc.) and to perform multi-tasking, where several tasks
take turns executing.
One example: A DSP processor may be required to perform non-DSP
jobs in order to eliminate a 'host' processor. An operating system may
be needed in order to share processing time and resources between the
DSP and non-DSP tasks.
An option for some DSP applications is to write your own DSP
'task-switching' or 'job allocating' operating system. Whether this is
the right choice for you depends on how involved your operating system
needs to be, and how much time you have available to spend writing it.
A number of companies now offer pre-written operating systems
that execute on DSP processors. In exchange for your money they offer
to save you the time and effort of writing and debugging your own
'operating system' or 'task switcher'.
These companies describe their products as 'real-time' operating
systems. What 'real-time' means is debated, but it normally means that
the maximum time for the operating system to respond to an external
event is known. The calculation for measuring this time involves adding
together interrupt response time, task switching time, and other
processor and operating system benchmarks. 'Real-time' also usually
means 'fast'. Embedded CPU or DSP tasks often require a 'real-time'
response time.
Prices and features vary. All companies charge for purchasing
their 'development environment', which allows you to develop code which
will run on their operating system. Some companies also charge a fee
for each product you build that includes their operating system
software. This is usually called a 'target fee' or 'runtime license'
fee. Some operating systems have no 'runtime license' fees.
It is *very* important to negotiate what the runtime license fee
will be *in advance*. If this price is not agreed upon in writing when
the development system is purchased, you could be in a bad position
later. You will have invested a lot of time and effort writing software
to work with a particular operating system, and when your creation is
produced you could discover that the 'runtime license fee' has increased
or is more than you can afford. Considering the amount of work you
would have invested in that operating system, you would be in a very
poor bargaining position.
You will also need to decide if having the source code for the
operating system is important to you. Some companies include it for
free, while others may charge extra.
Features for the DSP operating systems are listed below. Some
vendors claim that a 'No' listing for a feature doesn't necessarily mean
that their operating system is missing something you need. Some
companies state that certain features were not appropriate for either a
'DSP' or a 'real-time' operating system, and so they did not implement
them. Other companies stated that some features were not appropriate
for their targeted users.
One suggestion for comparing features: Make a list of the
features you *really* need and compare it against the list below.
Disclaimer: I've tried to make this information current,
accurate, and impartial, but I can't guarantee this. This document is
provided as is, with no warranty of any kind. You should contact the
vendors listed below for the best and most up-to-date information.
