Several years ago I used the 218x part because we just couldn't stomach 
the 24x assembly language.

More recently we held our noses and used the 28xx part -- it's very 
nice, once you figure out how to use TI technical support in lieu of 
good documentation.

Hi Georgi,

We don�t have any product based on SHARC processors. But I frequently
use the ADSP-21061 EZ-KIT for testing preliminary algorithms and as a
interface with our boards, also for testing purposes.
We make boards for the telecom market, actually based on ADSP-218x
family.
These DSPs do the signaling (E1, ISDN), DTMF generation/detection,
call progress, conferencing, audio play and record, audio volume, etc.
Yes, we use only assembly. When you have 60 channels, every
instruction represents almost half MIPS (@8k[Hz]).
The new boards must process 240 channels, and do things like echo
canceling, compression algorithms for VoIP, etc. (Our customers are
never satisfied!)

I don't like the idea of a DSP farm: communication overhead, a lot of
physical space and pricey. The 218x family is also fading away. So,
it's time to change the DSP.

BlackFin: fast, cheap, but has little internal memory, the program
memory cannot be used as data memory and vice-versa, has no host port
interface (until now), no conditional operations.

SHARC: floating point support and very pleasant to program but not so
fast as BlackFin (16 bit precision), no support for 16 bit operands
and also doesn't have the host port interface.

TigerSHARC: floating point support, 16 bit support, very fast, unified
memory map (there is no program/data memory), it's also pleasant to
program (except for deeper pipeline, principally the stalls from
compute clock dependency), has a powerfull external bus (the host has
full access to it) but it's power hungry and expensive.

TMSC5XX: I do hate it's assembly language.

TMSC6XX: I din't finished my homework yet!

I just indicated the points that are more important for me!

This really is unfortunate. But prices change and not always in the
direction we want. Out of curiosity, which SHARC DSP are you using now? What
are the time-critical functions in the new product? Are you planning to
optimize them in assembly?

Hi Georgi,

You can go now to ADI's web site, and at bottom right corner you will
find a picture of TigerSHARC processor and the advertisement "From
$34.95 to 4 GMACs, 24 Mbits and 5 Gbytes I/O". Clicking on it, you go
to a page that contain the text "Per-unit pricing for the ADSP-TS201,
ADSP-TS202 and ADSP-TS203 in 10,000 units at 500 MHz is $299, $149 and
$34.95 respectively."
That space at the bottom right corner is shared whith other ADI's
advertisements, so you probably must reload the page until you get the
TigerSHARC one.

So, maybe, we must say them to drop that advertisement!!!

One year ago, when I saw that advertisement, I started studying the
manuals, downloaded the VisualDSP, and recoded some routines for
performance testing. I really like the ADI's DSPs. I've been using the
SHARC and 21xx families for a long time. But now we have a new product
that needs a new and faster DSP, and the TigerSHARC seemed to be the
perfect fit. But $47 is not $35, and $61 is also far from what I was
expecting for 100 units (our projected initial consume will lie
between 100 and 1000 units/year). I had a lot of work to persuade
people here of using the TigerSHARC and now I'm not in very
confortable position.
Maybe I've made a mistake of trusting an early advertisement, but that
"lie" is still at ADI's web site.

Luiz,

We obtained our pricing directly from ADI, which told us that the
10,000-unit pricing for the TS203 is $47.  The prices you found on the web
site appear to be outdated.  ADI provided us with similar pricing in the
third quarter of last year, but the pricing for the TS203 has risen since
then.

Best Regards,
Georgi

Has anyone seen this page at BDTI's site?
http://www.insidedsp.com/showArticle.jhtml?articleID=29100482

I'm just curious about the price of ADI TS203 (TigerSHARC).

They say:
"TI’s TMS320C6418, announced this month, is a relatively
low-cost addition to the high-performance fixed-point ’C64x
family. The chip is sampling at 600 MHz and, like the DSP56321VF275,
will cost about $50 in 10,000-unit quantities",
"Analog Devices’ competing TigerSHARC family—the
ADSP-TS203S, which sells for $47 and runs at 500 MHz".
As a comparison I supose this price is for the same 10,000 units.
But at ADI's site we have: "Per-unit pricing for the ADSP-TS201,
ADSP-TS202 and ADSP-TS203 in 10,000 units at 500 MHz is $299, $149 and
$34.95 respectively."

So what's wrong?

It could be an mistake of BDTI people, but I asked ADI's
representative for TS203 price for 100 and 1000 units and I got:
100  units => $61
1000 units => $55

?????????????????????????????
