You are each talking about two seperate things : TI Modules (TIMs) and Multichip Modults (MCMs) The TIM module is a standard 4.2" by 2.5" daughterboard that contains a C40 and anything else the manufacturer decides to put on it - SRAM, DRAM, A/D, etc. The "mini-core on a stick" is as good an analogy as I've heard. Since these daughterboards all conform to a standard, users can mix and match modules from different manufacturers. An overview of the TIM can be obtain from the TI Hotline at 713-274-2442. Ask for literature number SPRV019. It also lists the North American manufacturers of the TIM. In production today are Spectrum Signal Processing (800-663-8986) and Traquair Data Systems (607-272-4417). Multichip modules on the other hand are a packaging technology for cramming a bunch of stuff on to a small surface area. TI has in development a dual and a quad C40 MCM. The dual is the only once that has been "officially" announced and will be sampling in about 3 months. The quad is not "officially" announced which is why the article mentioned didn't give more info. Note that MCMs are not meant as cost-reduction, but for surface area reduction. Military people are probably the only ones who can afford it. The industry as a whole, however, is pushing MCMs and we might see commercial ones in the future.

Hi fellow netters...
I have a question from a fellow, who would much appreciate if you could
reply to him directly, regarding the following:
>>From: RMADSEN@velara.sim.es.com (Ron)
>> The main thing I am looking for right now is self-instruction materials or
>> REALLY GOOD text books which could be used for self-instruction on
>> Calculus, numerical methods, and digital signal processing. I am finding
>> that I need to understand s-plane concepts, Laplace transforms, Fourier
>> Transforms, etc. My current level of comprehension is close to zero.
Note, he doesn't have access to comp.dsp, so direct replies to him are
requested. Thanks for your time.
