Are you sure you don't want to do real-time high-definition video
encoding while playing Quake while you're at it :-) Seriously, it sounds
like your device is no faster than an ARM 7, so wideband is out of the
question. Depending on the actual speed and your assembly skills, you
*may* be able to get narrowband running on it.
