when are these dsp cores introduced to market?

Hi,
    I hope to find when the dsp cores from TI, ADI, and Freescale are
introduced to market? I searched the internet, but haven't found the
useful information.
For TI, it seems that it first introduced C62x of C6000 seires to
market in 1999. C64, C64+ and C67?
For ADI,  blackfin was introduced to market in 2003?
For Freescale, when was SC140 introduced to market?
I hope to learn the history of DSPs from these three companies.

Thanks

How far back did you want to go?

IIRC, ADI introduced the ADSP2100 (the Blackfin/Sharc ancestor) in about 
1986.  TI had the TMS320C25 back then (and the TMS320C10 before that), 
and Motorola (now Freescale) had the 56000.  AT&T had the DSP16A.  But 
DSP's go back further than my own experience with them:

What do you mean by "introduced" ? Whitepaper publication? Samples 
available to public? Shipment in the production quantities?

There could be several years between those dates.

Useful for what?

It seems that you want to trace DSP evolution back to the 80s. If the
company websites don't have this data, then you will have to
reconstruct it from more web research. The info is out there.

That site is pretty accurate, but misses the key stage before 1978, when 
AMD was the king of DSP, with its excellent AM29xx and AM295xx bit slice 
range. Some might not count those, as they were typically not used to 
build programmable machines - though we built microcoded systems with 
them. However, they were the first serious coherent family of building 
blocks for DSP, and were widely used in military and telecoms systems. 
Plenty of TTL and ECL was used to construct DSP platforms before the AMD 
devices, but in very ad hoc ways.

Thanks, Vladimir
    I think maybe the applications determine the architecture of DSPs.
I hope to relate the architectures of DSPs to the applications.

    The high end applications of DPSs are video and wireless. Now I
work on video.
When C64 and blackfin are introduced, latest standards such as H.264
haven't been
finalized. When a new application emerges, which requires higher
performance,
for some DSP vendors, they can enhance their architectures of cores.
But for other DSP vendors, to enhance their architectures of cores is
not enough.
Maybe a new core architecture is needed.
