Hi,

It seems to me that that Blackfin is the processor of choice for your 
application. It's processing power is really high... do you really need 32 
bit precision?

Blackfin has special instruction to efficiently handle video streams, maybe 
you've seen that. Power consumption is low(-er than SHARC's)..

Regards,

I'm starting to look at a home project for creating a stand alone
webcam server. What I'd like to do is have 3-4 usb inputs for webcams,
convert the inputs into mpeg and send the data out an ethernet port. I
want to be able to support real-time (or close to it) video processing
and run a web server in the box also, as well as a few other
housekeeping functions and bells and whistles. I'm looking at several
options for the processor: the ADI Blackfin, the ADI Sharc and the Arm
processor. I'm leaning towards the Blackfin most, but I'd like to know
if it has the processing power needed (being 16 bit fixed point, rather

than the Sharc 32 bit floating point) to handle 4 camera inputs.


I've done some work with DSPs before ( Freescale 56K series) so I'm not

too worried about dealing with any of the procesors I mentioned. I just

need some idea on handling the mpeg processing from multiple cam
inputs. Any comments or suggestions would be appreciated. Thanks.
