Thomas/Ivan,
I was misleading, you are right, the codec is MPEG4-part2 (simple
profile), not MPEG4-part10 (H.264 basic profile). Sorry for the
confusion, I'm not sure were my mind is today.
Ivan, I would say that is possible to develop an H.264 decoder using
the hardware accelerators, my knowledge on this it that performance
bottleneck are mainly on data transfers, something I will not be
concerned if DM355 architecture is well used. But you better take
advice on the feasibility with a video codec expert taking a look on
the chip accelerators capabilities.
Regards,
Diego

Diego,
I was not aware of H.264, can you provide more info? The TI priority
has been on MPEG4 and JPEG encode and decode.

Hi Ivan,
The DM355 is powerful enough to play H.264, using TI codecs with his
acceleration engine (which does the heavy duty).
With ARM side audio decoders initial tests show around 30% cpu usage
(MP3 fixed point decoder).
We have most of the drivers ported to 2.6.22 (close enough for main
tree). And the beta code will be available for download soon
(hopefully tomorrow).
We also are offering beta reference designs based on it, and some
other software stacks (GUI, networking, multimedia).

Hi Thom,
Do you think this low cost DaVinci unit will be powerful enough to
play
H.264 video?

Dirk,
This is indeed a low cost DaVinci processor.
The DM355 DVEVM (board + dvsdk + 'demonstration version' of
montavista
pro v4.0 + beta 2.6.10 lsp) cost is $495 so we'll have a lower cost
option to help build the community.
The flow will be as follows: beta 2.6.10 MV LSP -> production
2.6.10
MV LSP -> driver up-port to git. The driver up-port will go a lot
quicker if we can get some help from the community. I see this
up-port
activity starting in a couple of months.

Don't know if this is really new but I just found
http://www.ti.com/corp/docs/landing/davinci/dm355.html?
DCMP=dsp_davinci_
dm355&HQS=Other+RA+dm355prbox
Seems to be low cost DaVinci processors without DSP (?).
