On Nokia N900, I have similar problems as Intel IPU3 hardware. Meeting notes say that pure software implementation is not fast enough, but that it may be useful for debugging. It would be also useful for me on N900, and probably useful for processing "raw" images =66rom digital cameras. There is sensor part, and memory-to-memory part, right? What is the format of data from the sensor part? What operations would be expensive on the CPU? If we did everthing on the CPU, what would be maximum resolution where we could still manage it in real time? Would it be possible to get access to machine with IPU3, or would there be someone willing to test libv4l2 patches? Thanks and best regards, Pavel --=20 (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blo= g.html --Kj7319i9nmIyA2yE Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEARECAAYFAlsqu04ACgkQMOfwapXb+vIa4wCgwmT55zoDfQFVYKryqeb95Bhx 1jwAnAn3xhrGeuiw5cmlIUu+4oZ5hN5y =bDCw -----END PGP SIGNATURE----- --Kj7319i9nmIyA2yE--
