Well, a good rule of thumb for generic 1-bit transfer is divide by 10 for the max speed in Bytes/sec you could expect, here we have 4-bit so the peak raw trasfer speed is ~10MBytes/sec *BUT* after Glamo pulls the data from the card, we have to sit there dragging it into the CPU memory, on top of card latencies and command setup the speed is way slower, still a decent ~2MBytes/sec each way IIRC. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkiIJfYACgkQOjLpvpq7dMq4pgCghgrmfW/rgPdMCgmnJssxnB10 rsAAni9A9EOVbDS9zwa51rj3CLqWCbOK =PhsH -----END PGP SIGNATURE----- _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
