Re: [Motion-user] Motion in an embedded device?

[Krzysztof B. <kb...@sy...>]

Let me add my 2 cents :)

I know arm pxa processors and use them but i haven't used them for this 
application but i think:
- it should be possible but with limitied functionality i mean mpeg 
(ffmpeg). i don't know how good (efficient) arm port is.
- any other things should work fine. (i guess)
- amount of input streams: 1 maybe 2 and no more.
- a 400MHz pxa255 has abt 390BogoMips. you can consider it as a PII 200MHz. 
anyway real performance is affected by sdram memory which usually works at 
100MHz. so performance for any image processing way be worse than expected 
as L1 cache is 32kB + 32kB and there is no L2 cache.
there is a chance and the advantage is that whole interface won't draw more 
than 3-4 Watts likely.
