Found a cache of transputer-related chips

Hi,

For anyone looking for inmos/st chips, the following distributor has
several A100s, C012, C011, T2xx, T4xx, T8xx and T9000 available:

Area 51 ESG - http://www.yqcomputer.com/

Dont know how much they are charging, but I frequently get emails from
part locators looking for chips (especially the C012/C011) to supply to
their customers...

Cheers,

Ram

I suspect you might be able to roll your own link adapters in CPLD, and A100
in FPGA relatively easily.

The T9000 though - I thought that never made it to mass production?

Or was full of bugs, ran to slow, or something.

T9000 got to production, but cost too much, for too little and was too
late. The ST20450 (I think that was the number); Yes, well now.... that
was full of bugs!!

Ram, what is an A100?

the A100 is a cascadable signal processor - bank of multiply accumulators on
chip, and a way to tie (cascade) chips together to build bigger MAC arrays.

And 2-dimensional, for image processing.

It was a true DSP in hardware, as opposed to a microcomputer optimised for
DSP in software.


And I have the (rare!) data book for the things! :-)

Don't suppose you could lend me it or scan it ;)
Please?

No. The A100 was 1-dimensional. It had, IIRC, 32 multiply-accumulate
stages. (You could cascade them together to do 2-D processing
of course.)

The A110 was 2-dimensional having 3 on-chip line-stores and 21
multiply-accumulate stages organised as 3 lines of 7 taps.

Ah, that's the one I was thinking of.

It is a thick book - about an inch.

Do you have any particular items that interest you?

I can scan the contents pages for your perusal.

I actually have the IMSB009 and the software for it as well. It comes
with a simulator for the A100. I also have the databook and the single
sheets as well. But, lately, I have been drowning with work to a point
where I cant even look at a *** :-( You can download the drivers
and software here for the time being until I get around to adding a page
for it:


http://www.yqcomputer.com/

Note that it requires the IMSD700 (TDS system), but it does come with
source so you can re-compile it using the toolset's iflat utility. The
TDS can be found here:


http://www.yqcomputer.com/

Note that this is the COMMERCIAL version as distributed by INMOS, but it
has been released freely for personal use. The source code can be found
here (which was also released):

http://www.yqcomputer.com/

A quick search of Amazon.com found the forementioned INMOS DSP book at:

Cheers,

Ram

Also, an A100 simulator (and the other image processing CPUs) can be
found on the INMOS file archive at:


http://www.yqcomputer.com/

And yes, the DSP book is quite RARE and difficult to obtain. It took me
about 3 years to pick one up!

Cheers,

Ram

That is true, but some shops just want a drop-in replacement to handle
their existing designs. This is the first advice I give to these part
locators, but it really all depends on their customers needs. A
re-design of an existing design costs money and possibly locating the
original designer(s) or knowledgable engineers.

Cheers,

Ram

Since, the question has been answered by others, I figure it isnt
necessary for me to give a response ;-)

Except, that the IMSB009 has 4 A100s and a size-4 TRAM site to do some
serious parallel DSP work. The one that I am specifically looking for
is the INMOS image processing tram that contains several A110s and a T8
transputer in a size-4 package. Totally neat! I want one!!!

Cheers,

Ram
