Hi Raymond

Motorola offers quite a lot of paper about the DSP56000/1. Ask there for
literature. 
I'm designing a multi DSP system for parallel processing. As RAM I use
the Motorola DSPRAM MCM56824 (8k x 24 bit) plus common chips (32k x 8 bit)
for extended appliactions. Decoding is done via GALs (Lattice 20V8, 16V8).
This is a fast (some ns) and flexible way of decoding and partitioning.

As peripherals serve standard 68xxx devices, but they require different
bus signals and timings. This interface is done with GALs.

My IO devices are Crystal converters: CS4328 (2 x 18 bit D/A)
                                      CS5326 (2 x 16 bit A/D)

That`s all for the moment.. (I mean: good luck!)

Several releases have occured since V2.10 for the TMS320C30 C Compiler.
Function prototyping was offered in V3.00. The latest release is V4.40 with

I'd suggest to get the application notes from Motorola. They show
example schematics and give some details on programming. Motorola
also has a BBS where you can download example software including
the monitor program used on Motorolas development system.

As for hardware, it depends. If you build a small system, the 8x24bit
RAM from Motorola helps to make a very compact design. For me this
memory size wasn't sufficient, so I used 3 32kx8 chips.

Hope this helps,

Hi, all!  Sorry to intrude...
Years ago I used to work on a GenRad system, which was made up of a PDP-11/35
and a couple of racks of custom hardware (for sampling, FFTs, windowing...).
The language used to control all this stuff was called TSL - Time Series
Language, I believe.  

My question: does anyone have one of those little yellow covered TSL reference
manuals?  I'm feeling nostalgic and would like to see what it was like again.

There are so many applications that would benefit from Digidesigh hardware

could really benefit from such support.

The way I understand it, the real bottleneck is some sort of information
witholding from Digidesign to make publicly available their sound drivers

My interest in this question is to have access to a better "dsp" object

Hi Jeff,
   The subjective speech quality of (a correctly implemented) 4800bps
CELP speech compression system is very impressive and is quite suitable
for telephone-quality speech.

   My company, Analogical Systems, has implemented a U.S.F.S 1016 CELP
vocoder based upon a single 27MHz Motorola DSP56001 (the analyzer
searches the entire 512 stochastic vector codebook in real time).
The DSP56001 source and/or object code is available for licensing.

   Demonstration systems are also available, based upon Ariel Corp's
PC-56 or PC-56D boards. A complete demonstration system (including the
Ariel PC-56 board) is available from Analogical Systems for only $595.
This would allow you to assess the speech quality for yourself.

   Feel free to contact me directly at Analogical Systems, 415-323-3232.

Cole Erskine

There's a company in Boston called Sonitech, Int'l, 617-235-6824, who will 
be marketing an emulator & debugging package for the Sun SparcStation (sBus). 
Full X-Windows support, as well as C30 AND C40 support. This should be out by 
mid-October. It's a good, reputable company. You should give them a call.
I don't know the final pricing structure, but look to pay about $6K.

Although floaing point numbers are supported by the 56k C compiler,
Linpack wouldn't be a very good benchmark for fixed point processors,
IMHO. Linpack performance is dominated by floating point performance.
Can you give us some insight?

Annotate is a Motorola program that reads the debug directives in the

Have you looked at the CYPRESS CY7C9101.
This component is effectivly a collection of 4 2901s in a single package.
We have used it in the past to make a 32bit Z-buffer processor, and found
that the price performance was far better than any other choice we could

Hi !

I've designed a 56K system some time (with many aids as I never did such a
large project before) ago using 3 128Kx8 chips to provide P: and X: memory
at a time... This is possible because the 56000/1 can only adress ONE of the
three memory spaces at a time...

I found that there are very little applications using more that 16K of P-Space
But as I used the Host-Interface to upload new code-segments it might be useful
to have more if You want to develop and run 56K code without resetting it...

Your compiler is about a hundred years old. Version 4.4 was out end

TI offers a TMS320C30 EVM for $995. It is a PC plug-in board and includes
debugger software as well as an assembler/linker. The board features a
TLC32044 (linear codec) on one serial port and an off-board connector for the
second serial port. The board and software are easy to use and two
applications are also provided to help you get started.

Thanks for all those people who replied to my post !

I have now got the fft algorithm from `numerical recipes
in C' (which I looked for but couldn't get hold of the book)
which looks just right

Thanks again

Subject: Frequency-domain curve-fitter wanted

Hi,

I am interested in curve-fitting sound pressure and impedance
response functions in the frequency domain using a rational
fraction polynomial formulation. Does anyone have any source
code to such a routine in Fortran, Pascal, or C?.

I have seen a paper titled "A Frequency Domain Curve Fitting
Algorithm With Improved Accuracy", by Jim Adcock (Hewlett-
Packard) and Ron Potter (Consultant) that was presented at a
modal analysis convention a few years ago.

The above algorithm can fit to data that is log-spaced in the
frequency domain, which is the common form for audio/acoustic
measurements as published in loudspeaker manufacturers data
sheets.

My application is related to modelling of loudspeaker systems so
that it will be possible to design crossover networks that take
into account each driver's natural response characteristics.

Any suggestions or pointers where I could obtain program source
code that implements this algorithm will be gratefully received.

Maybe even someone from Hewlett-Packard can help me?

Thank you.
