Hi Ed,
Nice to hear from you again. I still appreciate all your help with
umon ;)
I would say the main difference is the ARM core. OMAP3 uses a Cortex-
A8 super-scalar processor at ~500Mhz and this reflects a bit on the
underlaying peripheral architecture and devices, provides floating
point unit and Neon SIMD instruction set, while the Davinci cores are
ARM926EJS at ~270Mhz, and use soft-float. DSP-wise they are pretty
similar. Other than that the peripherals capabilities are similar and
for all tastes. Also the OMAP3 offers OpenGL graphics as well if
that's useful for your needs.
The APIS for accessing the DSP from Linux are standardized if you use
DSPLink and CodecEngine, since Davinci and OMAP chips are supported by
CodecEngine. There is another API called dsp bridge, but is only used
in OMAP space.
The Davinci wiki is a good place to get more information on any
particular subject you may be interest. You can also can ask around
here for the particular differences on any area that you may looking at.

Hi...
I'm brand new to the list and essentially brand new to DaVinci/OMAP.
I'm trying to investigate different embedded options for image
processing
applications. I've played around with Blackfin a bit, now wanna
look at the TI stuff. Can anyone point me to a website/document/
whatever
that summarizes the difference between the OMAP family and the DaVinci
family of SOCs? At first glance they seem pretty similar.
Thanks
Ed
