What about an FPU? It probably wouldn't eat much power, and would help a *lot* for audio applications, since stuff wouldn't need to be rewritten in fixed point arithmetic. On a related note (and perhaps on the wrong end of an NDA), any idea what the specs are on the glamo's built in openrisc processors? Can they do floating point? Randomly access memory? How many of them are there? If they're beefy enough, with the right drivers (like CUDA), I think we'd have the bus bandwidth to offload audio processing (ogg decoding) to them, assuming the bus is symmetric: 48khz * 16bit/sample * 2channels = 187.5 kilobytes / sec = 1.4 mbit/sec -Rusty _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
