The dogfish is a shark much loved in British fish and chip shops. :-)

I suspect they hit a road block when Intel abandoned the Blackfin work, after getting their butt kicked in the cellular market. ADI recently sold much of their wireless business. They don't seem to have been doing awfully well in that area. Maybe if WiMax achieves some success it could be a chance for them to recover lost ground. Steve

There is a Blackfin Shark (as well as Tuna). So I don't think ADI was thinking catfish..... Al Clark Danville Signal Processing, Inc.

Gee, you're supposed to be the ADI saleman around here. Even Wikipedia can help you here. :-) Catfish and dogfish are actually sharks. Catfish are mostly freshwater. The blackfin shark is one of the few catfish which can tolerate brackish water. Steve

I guess the significance of that might need pointing out to those who have not encountered the ADI Blackfin. The Blackfin core was designed to be a pretty good general purpose MCU core and a pretty good DSP core at the same time. Its the first substantially successful attempt at achieving that. I've never seen a statement that this was the basis of the name choice, but I assume a shark that can stand both fresh and salt water seemed appropriate. Steve

We have a new Blackfin and Sharc flash programmer that I wanted to call "remora" I thought this was a lot better name than "suckerfish" Alas, Bittware beat us to it with an FPGA mezzanine card for their TigerSharc boards. --- How's that for shameless commerce

Being from Minnesota, I have caught both catfish and dogfish. I never heard either was some kind of shark. I'm not even sure what we call a dogfish (bowfin) is the same fish that you're referring to. Al Clark Danville Signal Processing "ADI board designer, manufacturer and salesman"

Actually that was a re-use of the name. The first BittWare Remora product was an add-on memory module for SHARCs, but since it was already obsolete and it was such a great name, we re-used it for the FPGA module. We also had another old add-on memory module called Chum. I'm not sure I'd call it shameless (2 drink minimum not required), but the SHARC brand made naming our products easy, as they were all types of sharks. Snaggletooth, Blacktip, Whitetip, and Hammerhead were popular, while others, like Megamouth and Goblin never saw the light of day. A naming battle I lost was calling an 8 channel audio I/O (analog and digital) module Octapus. And I really wished the plural form was OctapAES, as it supported it. I had not heard about the dual ability of the Blackfin being thought about in terms of its name - perhaps, but we just figured they wanted to draw on the SHARC's popularity, even though it is not a SHARC. ----------- Ron Huizen BittWare
Intel Atom is beginning to look interesting.

How are TI's floating point DSPs compared to TigerSHARC? My experience
with ADI DSPs is somewhat dated. I wish TI processors had those link
ports.

Isn't Atom the name for their new low power notebook chipset?

Yes, it is. I read that its power consumption is in 0.6 to 2 watt
range depending on the operating conditions. This may pose some threat
to traditional floating point DSPs. I know that in Medical Imaging
industry several big players have stopped using traditional DSPs for
back-end processing.

Only TI seems to address broad market needs better than any other DSP
vendor. They have been continuously improving their fixed point line
bringing 64x+ core into several of their offerings. Their new OMAP
application processor looks a lot like a DaVinci.

I haven't looked into this much. One of my colleagues' dream is that
some day all real-time signal processing code will be written in
Matlab. (Too bad, Mathworks is not a public company ;))

Its 0.6 to 2W for a relatively slow device. I don't see what makes that interesting against a dedicated DSP chip.

Medical imaging is Ease of development sensitive Not too power or cost sensitive Not too space sensitive With the floating point capabilities of a current Pentium, basing all image processing on either FPGA solutions or Pentium/Athlon off the shelf boards makes perfect sense. I don't see things like base stations going that way any time soon.

The new OMAP emphasises a fast Cortex applications processor. The DaVinci emphasises the DSP power for things like video. I'm not sure I see too much common ground there.

I wonder if that is the day when all innovation will cease in the world of signal processing? :-) Steve
